This document describes the changes made to the asn1 application.
Asn1 5.3.1
Fixed Bugs and Malfunctions
Fixed a cosmetic but harmless issue with the ASN.1 compiler passing on the
undec_rest
option to the Erlang compiler.
Asn1 5.3
Fixed Bugs and Malfunctions
Multiple bugs has been eliminated in the specialized decode feature.
Own Id: OTP-18813 Aux Id: PR-7790
Improvements and New Features
Specs have been added to all
asn1ct
API functions.Own Id: OTP-18804 Aux Id: PR-7738
The documentation has been migrated to use Markdown and ExDoc.
Own Id: OTP-18955 Aux Id: PR-8026
The
jer
(JSON Encoding Rules) for ASN.1 now use the newjson
module for encoding and decoding JSON. Thus, there is no longer any need for an external JSON library.Own Id: OTP-19018 Aux Id: PR-8241
Asn1 5.2.2
Fixed Bugs and Malfunctions
An ASN.1 module that contains named
BIT STRING
values would fail to compiled if both the BER and JER back-ends were enabled.Own Id: OTP-19039 Aux Id: GH-8291, PR-8297
Asn1 5.2.1
Fixed Bugs and Malfunctions
Fix benign warning from gcc 11 about mismatching call to free().
Own Id: OTP-18844
Asn1 5.2
Fixed Bugs and Malfunctions
The ASN.1 compiler would ignore a constraint such as
(SIZE (1..4), ...)
, causing incorrect behavior of the encoding and decoding function for the PER and UPER backends. Corrected to handle the constraint in the same way as(SIZE (1..4, ...))
.Own Id: OTP-18729 Aux Id: PR-7575
Improvements and New Features
The JER backend has been internally refactored in a way that is compatible for applications that use the documented API. However, for a group of ASN.1 modules that depend on each other (for example,
S1AP-PDU-Descriptions
, S1AP-Contents, and so on), all modules in the group must be recompiled if on of the group members is recompiled.Own Id: OTP-18748 Aux Id: ERIERL-957, PR-7637
Asn1 5.1
Fixed Bugs and Malfunctions
The ASN.1 compiler used to reject correctly specified RELATIVE-OID values containing other RELATIVE-OID values. This is now corrected.
Own Id: OTP-18534 Aux Id: ERIERL-737, PR-7039
Improvements and New Features
Minor code improvements.
Own Id: OTP-18441
Handling of
on_load
modules during boot has been improved by adding an extra step in the boot order for embedded mode that runs allon_load
handlers, instead of relying on explicit invocation of them, later, when the kernel supervision tree starts.This is mostly a code improvement and OTP internal simplification to avoid future bugs and to simplify code maintenance.
Own Id: OTP-18447
Asn1 5.0.21.1
Fixed Bugs and Malfunctions
Fix benign warning from gcc 11 about mismatching call to free().
Own Id: OTP-18844

andSET OF
constructs with 16384 items or more is now supported.Own Id: OTP-18245 Aux Id: ERIERL-859
Asn1 5.0.20
Improvements and New Features
There is a new configure option,
--enable-deterministic-build
, which will apply thedeterministic
compiler option when building Erlang/OTP. Thedeterministic
option has been improved to eliminate more sources of non-determinism in several applications.Own Id: OTP-18165 Aux Id: PR-5965
Asn1 5.0.19
Fixed Bugs and Malfunctions
The atom
maybe
has been quoted in the source code.Own Id: OTP-17980

maps
option in combination with thejer
backend.Own Id: OTP-17959 Aux Id: GH-5757
Asn1 5.0.17
Fixed Bugs and Malfunctions
A parameterized type with a SEQUENCE with extension ("...") made the compiler backend to crash. The previous fix for this in GH-4514 was not complete.
Own Id: OTP-17522 Aux Id: GH-4902
Asn1 5.0.16
Fixed Bugs and Malfunctions
Fixed a bug in the
asn1
compiler that potentially could cause it to fail to open a file.Own Id: OTP-17387 Aux Id: OTP-17123
Asn1 5.0.15.1
Fixed Bugs and Malfunctions
A parameterized type with a SEQUENCE with extension ("...") made the compiler backend to crash. The previous fix for this in GH-4514 was not complete.
Own Id: OTP-17522 Aux Id: GH-4902
Asn1 5.0.15
Fixed Bugs and Malfunctions
A parameterized type with a SEQUENCE with extension ("...") made the compiler backend to crash.
Own Id: OTP-17227 Aux Id: GH-4514
For JER encoding rules an INTEGER value outside the declared range is now reported as error during decode.
Own Id: OTP-17306 Aux Id: ERIERL-506
Improvements and New Features
For the JER encoding rules, the declared order of the fields in a SEQUENCE is now maintained in the resulting JSON object. Previously a map was used which caused an undefined order of the fields which was not friendly for debugging.
Own Id: OTP-17297 Aux Id: ERIERL-607
Asn1 5.0.14
Improvements and New Features
Changes in order to build on the Haiku operating system.
Thanks to Calvin Buckley
Own Id: OTP-16707 Aux Id: PR-2638
Asn1 5.0.13

Improvements and New Features
Refactored the internal handling of deprecated and removed functions.
Own Id: OTP-16469
Improve handling of ellipsis in a CHOICE
Own Id: OTP-16554 Aux Id: ERL-1189
Asn1 5.0.12
Improvements and New Features
Dialyzer warnings of type
no_match
are now suppressed in the generated files.Own Id: OTP-16636 Aux Id: ERIERL-145
Asn1 5.0.11
Improvements and New Features
The compiler now has limited support for the JSON encoding rules (ITU-T X.697 ASN.1 encoding rules: Specification of JavaScript Object Notation Encoding Rules).
Own Id: OTP-16030
Asn1 5.0.10
Improvements and New Features
Fix 'DEFAULT' with 'OCTET STRING' and 'SEQUENCE OF CHOICE' with extensions.
Own Id: OTP-16542 Aux Id: PR-2159
Asn1 5.0.9
Fixed Bugs and Malfunctions
All incorrect (that is, all) uses of "can not" has been corrected to "cannot" in source code comments, documentation, examples, and so on.
Own Id: OTP-14282 Aux Id: PR-1891
Corrected problems with the following value definitions:
- value of SEQUENCE OF CHOICE with extensions
- value of CHOICE with extensions
- DEFAULT used with OCTET STRING
Own Id: OTP-15697 Aux Id: PR-2159
Asn1 5.0.8
Fixed Bugs and Malfunctions
Handle erroneous length during decode (BER only) without crashing.
Own Id: OTP-15470 Aux Id: ERIERL-278
Asn1 5.0.7
Fixed Bugs and Malfunctions
A bug in ASN.1 BER decoding has been fixed. When decoding a recursively enclosed term the length was not propagated to that term decoding, so if the length of the enclosed term was longer than the enclosing that error was not detected.
A hard coded C stack limitation for decoding recursive ASN.1 terms has been introduced. This is currently set to 8 kWords giving a nesting depth of about 1000 levels. Deeper terms can not be decoded, which should not be much of a real world limitation.
Own Id: OTP-14440 Aux Id: ERIERL-220
Asn1 5.0.6
Improvements and New Features
Update to use the new string api instead of the old.
Own Id: OTP-15036
Asn1 5.0.5.2
Fixed Bugs and Malfunctions
Handle erroneous length during decode (BER only) without crashing.
Own Id: OTP-15470 Aux Id: ERIERL-278

Own Id: OTP-14440 Aux Id: ERIERL-220
Asn1 5.0.5
Fixed Bugs and Malfunctions
Dialyzer suppression has been added for the generated ASN.1 helper function to_bitstring/1 that previously created irrelevant warnings.
Own Id: OTP-13882 Aux Id: ERIERL-144
Asn1 5.0.4
Fixed Bugs and Malfunctions
There was a issue with BER encoding and the
undec_rest
option in generated decoders. An exception could be thrown instead of returning an error tuple.Own Id: OTP-14786 Aux Id: ERL-518
The asn1ct:test functions crashed on decoders generated with options
no_ok_wrapper
,undec_rest
.Own Id: OTP-14787 Aux Id: ERL-518
Asn1 5.0.3
Fixed Bugs and Malfunctions
Compiling an ASN.1 module using the option {n2n, EnumTypeName} when EnumTypeName contains a hyphen like for example Cause-Misc caused syntax errors when compiling the generated Erlang code. This is now corrected.
Own Id: OTP-14495 Aux Id: ERL-437
Asn1 5.0.2
Fixed Bugs and Malfunctions
Default values now work in extension for PER, so if you give the atom
asn1_DEFAULT
instead of a value it will become the default value.Own Id: OTP-13011 Aux Id: ERIERL-60
Asn1 5.0.1
Fixed Bugs and Malfunctions
Fixed compilation error of generated code caused by a missing quotation of function names as part of an external call for encoding.
Own Id: OTP-14519 Aux Id: ERIERL-49
Asn1 5.0
Fixed Bugs and Malfunctions
Add compile option
-compile(no_native)
in modules withon_load
directive which is not yet supported by HiPE.Own Id: OTP-14316 Aux Id: PR-1390
Improvements and New Features
The
error
tuple returned from theencode
anddecode
functions will now include the stack backtrace to make it easier to understand what went wrong.Own Id: OTP-13961
The deprecated module
asn1rt
has been removed. The deprecated functionsasn1ct:encode/3
andasn1ct:decode/3
have been removed. The undocumented functionasn1ct:encode/2
has been removed.* POTENTIAL INCOMPATIBILITY *
Own Id: OTP-14146
The new '
maps
' option changes the representation of the typesSEQUENCE
andSET
to be maps (instead of records).Own Id: OTP-14219
Asn1 4.0.4
Fixed Bugs and Malfunctions
Compiling multiple ASN.1 modules in the same directory with parallel make (make -j) should now be safe.
Own Id: OTP-13624
Asn1 4.0.3
Improvements and New Features
Internal changes
Own Id: OTP-13551
Asn1 4.0.2
Fixed Bugs and Malfunctions
When compiling to the PER format, the ASN.1 compiler would crash when attempting to compile an ASN.1 module with a constrained INTEGER with more than 65536 values and named values. (Thanks to Ingars for reporting this bug.)
Own Id: OTP-13257
The ASN.1 compiler will now emit Dialyzer suppressions for improper lists. Thus, there is no longer any need to use
--Wno_improper_lists
when analyzing modules generated by the ASN.1 compiler.Own Id: OTP-13324
Asn1 4.0.1
Fixed Bugs and Malfunctions
Trying to encode an empty named BIT STRING in BER would fail with a
function_clause
exception. (Thanks to Svilen Ivanov for reporting this bug.)Own Id: OTP-13149
Asn1 4.0
Fixed Bugs and Malfunctions
Many bugs have been eliminated in the ASN.1 compiler so that it can now successfully compile many more ASN.1 specifications. Error messages have also been improved.
Own Id: OTP-12395
Improvements and New Features
The documentation for
asn1ct:test/1,2,3
andasn1ct:value/2
has been updated with information about the limitations of the functions.Own Id: OTP-12765 Aux Id: seq12866, seq12867
Asn1 3.0.4
Fixed Bugs and Malfunctions
The ASN.1 compiler would crash if a SEQUENCE ended with a double set of ellipses (
...
).Own Id: OTP-12546 Aux Id: seq12815
Asn1 3.0.3
Fixed Bugs and Malfunctions
When decoding BER, primitives with an indefinite length will be immediately rejected. (Thanks to Simon Cornish for reporting this bug.)
Own Id: OTP-12205
BER: A bug with compliance to X.680 (200811) s31.2.7 has been fixed. Basically, when TagDefault is AUTOMATIC then tags are IMPLICIT unless EXPLICIT is given.
Own Id: OTP-12318
Usage of the
EXTERNAL
1994 variant type was broken.Own Id: OTP-12326
Asn1 3.0.2
Fixed Bugs and Malfunctions
Several problems where the ASN.1 compiler would crash when attempting to compile correct specifications have been corrected.
Own Id: OTP-12125
Robustness when decoding incorrect BER messages has been improved.
Own Id: OTP-12145
Asn1 3.0.1
Fixed Bugs and Malfunctions
The ASN.1 compiler now generates code that don't trigger Dialyzer warnings. Along the way, a few minor bugs were fixed.
Own Id: OTP-11372 Aux Id: seq12397
Asn1 3.0
Fixed Bugs and Malfunctions
Subtyping an extensible ENUMERATED would cause an compilation error. (Thanks to Morten Nygaard Åsnes for reporting this bug.)
Own Id: OTP-11700
When specifying the value for an OCTET STRING in a specification, the ASN.1 standard clearly states that the value must be either a bstring or an hstring, but NOT a cstring. The ASN.1 compiler will now generate a compilation error if the value of an OCTET STRING is given as a character string.
That is, the following example is now illegal:
string OCTET STRING ::= "Now illegal"
* POTENTIAL INCOMPATIBILITY *
Own Id: OTP-11727
Application upgrade (appup) files are corrected for the following applications:
asn1, common_test, compiler, crypto, debugger, dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe, inets, observer, odbc, os_mon, otp_mibs, parsetools, percept, public_key, reltool, runtime_tools, ssh, syntax_tools, test_server, tools, typer, webtool, wx, xmerl
A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP.
(Thanks to Tobias Schlager)
Own Id: OTP-11744
Improvements and New Features
By giving --enable-static-{nifs,drivers} to configure it is now possible to statically linking of nifs and drivers to the main Erlang VM binary. At the moment only the asn1 and crypto nifs of the Erlang/OTP nifs and drivers have been prepared to be statically linked. For more details see the Installation Guide in the System documentation.
Own Id: OTP-11258
Code generation for the
per
anduper
backends has been somewhat improved.Own Id: OTP-11573
The OCTET STRING and BIT STRING types now have a more natural mapping to Erlang types (binary and bitstring, respectively), which is more efficient and will avoid useless conversions between lists and binaries/bitstrings.
This is an incompatible change. To revert to the old mapping to support existing applications, use the
legacy_erlang_types
option.Impact: There is a potential for better performance, as it is now possible to avoid conversions between lists and binaries both in the generated ASN.1 encode/decode code and in the application itself.
* POTENTIAL INCOMPATIBILITY *
Own Id: OTP-11594
All functions in the
asn1rt
module, as well asasn1ct:decode/3
andasn1ct:encode/3
, are now deprecated.Own Id: OTP-11731
Generated .hrl files are now protected from being included more than once.
Own Id: OTP-11804
Asn1 2.0.4
Fixed Bugs and Malfunctions
The default value for a
BIT STRING
would not always be recognized, causing the encoding to be incorrect for the DER/PER/UPER encodings.Own Id: OTP-11319
The ASN.1 application would fail to build if the
.erlang
file printed something to standard output.Own Id: OTP-11360
An union of integer ranges in an INTEGER constraint could sometimes be interpreted as the intersection of the range.
Own Id: OTP-11411 Aux Id: seq12443
Extensible, multiple single value constraints (such as
INTEGER (1|17, ...)
) would be incorrectly encoded.Own Id: OTP-11415
The ASN.1 compiler would fail to compile a constraint with values given for the extension part (such as
INTEGER (1..10, ..., 11..20)
).Own Id: OTP-11504
Improvements and New Features
The new option '
no_ok_wrapper
' generates M:encode/2 and M:decode/2 functions that don't wrap the return value in an {ok,...} tuple.Own Id: OTP-11314
Asn1 2.0.3
Fixed Bugs and Malfunctions
Open types greater than 16383 bytes will now be correctly encoded and decoded.
Own Id: OTP-11262 Aux Id: seq12386, OTP-11223
Improvements and New Features
For the PER and UPER formats, code generation especially for encoding has been improved.
When encoding BIT STRINGs, values longer than the maximum size for the BIT STRING type would be truncated silently - they now cause an exception.
Open types greater than 16383 bytes will now be correctly encoded and decoded.
IMPORTANT NOTE: For ASN.1 specifications that depend on each other, such as the S1AP-* specifications, it is important to recompile all specifications (compiling some with this version of the compiler and some with an older version will not work).
Own Id: OTP-11300
Asn1 2.0.2
Fixed Bugs and Malfunctions
Fix some Makefile rules that didn't support silent rules. Thanks to Anthony Ramine.
Own Id: OTP-11111
PER/UPER: A semi-constrained INTEGER with a non-zero lower bound would be incorrectly decoded. This bug was introduced in R16.
PER/UPER: Given
INTEGER (10..MAX, ...)
, attempting to decode any integer below 10 would cause the encoder to enter an infinite loop.PER/UPER: For a type with an extensible SIZE constraint, sizes outside of the root range were incorrectly encoded.
Given a constraint such as
(SIZE (5, ...))
, encoding a size less than 5 would fail (PER/UPER). Similarly, for BER decoding would fail.PER: The encoder did not align a known multiplier string (such as IA5String) of length 16 bits (exactly) to an octet boundary.
In rare circumstances, DEFAULT values for the UPER backend could be wrongly encoded.
Own Id: OTP-11134
UPER: The compiler would crash when compiling an ENUMERATED having more than 63 extended values.
PER/UPER: A SEQUENCE with more 64 extended values could not be decoded.
Own Id: OTP-11153
When decoding a SEQUENCE defined inline inside a an extension addition group, the record named generated by the decoding code would not match the name in the generated .hrl file.
Own Id: OTP-11154 Aux Id: seq12339
Improvements and New Features
Postscript files no longer needed for the generation of PDF files have been removed.
Own Id: OTP-11016
Asn1 2.0.1.2
Fixed Bugs and Malfunctions
When an object set is an actual parameter, the extension marker for the object set could get lost (which would cause the decoding of unknown values to fail).
Own Id: OTP-10995 Aux Id: seq12290
Asn1 2.0.1.1
Fixed Bugs and Malfunctions
The generated decoder for the 'per' and 'uper' backends did not correctly decode ENUMERATEDs with a single value.
The generated encoder for the 'per' and 'uper' backends generated an empty binary for a top-level type that did not need to be encoded (such as an ENUMERATED with a single value). The correct result should be a binary containing a 0 byte.
Own Id: OTP-10916 Aux Id: seq12270
Asn1 2.0.1
Fixed Bugs and Malfunctions
Fixed broken table constraints within a SET OF or SEQUENCE OF for the BER backend.
Own Id: OTP-10853 Aux Id: seq12245
Asn1 2.0
Fixed Bugs and Malfunctions
Encoding SEQUENCEs with multiple extension addition groups with optional values could fail (depending both on the specification and whether all values were provided).
Own Id: OTP-10664
Improvements and New Features
The options for the ASN.1 compiler has been drastically simplified. The backend is chosen by using
ber
,per
, oruper
. The optionsoptimize
,nif
, anddriver
are no longer needed. The old options will still work, but will issue a warning.Another change is that generated
encode/2
function will always return a binary (some backends used to return an iolist).* POTENTIAL INCOMPATIBILITY *
Own Id: OTP-10410 Aux Id: kunagi-254 [165]
The ASN.1 compiler generates faster decode functions for PER and UPER. Some minor improvements have also been made for PER/UPER encoding, and to the BER backend.
Own Id: OTP-10519 Aux Id: kunagi-322 [233]
The ASN.1 compiler will now always include necessary run-time functions in the generated Erlang modules (except for
asn1rt_nif
which is still needed). If the option 'inline
' is used the ASN.1 compiler will generate a warning. But if '{inline,OutputFile}
' is use, the ASN.1 compiler will refuse to compile the file. (Use a.set.asn
file if you need to remove the output file.)The '
BIT STRING
' type will now be decoded as Erlang bitstrings by default. Use the newlegacy_bit_string
option to encode as lists of ones and zeroes. (Thecompact_bit_string
option still works as before.)Open types are now always returned as binaries (when there is no information allowing them to be decoded).
* POTENTIAL INCOMPATIBILITY *
Own Id: OTP-10588 Aux Id: kunagi-341 [252]
Asn1 1.8.1
Fixed Bugs and Malfunctions
ASN.1 decoders generated with the options
-bber_bin +optimize +nif
would decode open types with a size larger than 511 incorrectly. That bug could cause decoding bypublic_key
to fail. The bug was in the NIF libraryasn1_erl_nif.so
; therefore there is no need re-compile ASN.1 specifications that had the problem.Own Id: OTP-10805 Aux Id: seq12244
Encoding SEQUENCEs with multiple extension addition groups with optional values could fail (depending both on the specification and whether all values were provided).
Own Id: OTP-10811 Aux Id: OTP-10664
Asn1 1.8
Fixed Bugs and Malfunctions
Encoding and decoding of integer ranges can now be done with an upper bound larger than the previous limit of 16^10. The new upper bound in per encoding and decodings for constrained whole numbers is 2^2040 (close to 16^508)
Own Id: OTP-10128
Per encoding/decoding now works correctly for single value subtyping of an integer type where a subtype is a predefined value. Previously a predefined value could cause a non-valid range-check in the generated Erlang code for per encoding/decoding due to a bug in the constraint checking.
Own Id: OTP-10139
Fix typo error in selected decode function (Thanks to Artem Teslenko)
Own Id: OTP-10152
Better error indication when detecting unexpected tags during decoding of BER encoded data.
Own Id: OTP-10186

Own Id: OTP-10233
Improvements and New Features
Add support for multiple ExtensionAdditionGroups
Own Id: OTP-10058
Add support for extensible enumeration types in n2n generated functions.
Own Id: OTP-10144
Asn1 1.7
Improvements and New Features
Some ASN.1 INTEGER type and SEQUENCE constructor variants previously not handled by the ASN.1 compiler are now correctly handled
Own Id: OTP-9688
An INTEGER with a value constraint where unions are used e.g. X1 ::= INTEGER (1..4 | 6 | 8 | 10 | 20) is not handled correctly. For PER the value is encoded in wrong number of bits.
Own Id: OTP-9946
Asn1 1.6.19
Improvements and New Features
The linked-in driver used for ber decode and per encode has been replaced with nifs. To enable the usage of nifs pass the nif option to erlc or asn1rt:compile when compiling. If you previously used the linked-in driver, you have to recompile your ASN1 modules with the current version of asn1 application as the linked-in driver modules have been removed.
* POTENTIAL INCOMPATIBILITY *
Own Id: OTP-9419
A few of the heavy calculations which are done for encoding and decoding operations when dealing with SEQUENCE OF and DEFAULT in runtime have been moved to be done in compile time instead.
Own Id: OTP-9440
When compiling an ASN.1 ber module with the +nif option, the module will use a new nif for ber encoding, increasing performance by about 5%.
Own Id: OTP-9441
Tuple funs (a two-element tuple with a module name and a function) are now officially deprecated and will be removed in R16. Use '
fun M:F/A
' instead. To make you aware that your system uses tuple funs, the very first time a tuple fun is applied, a warning will be sent to the error logger.Own Id: OTP-9649
Asn1 1.6.18
Fixed Bugs and Malfunctions
Implement or fix -Werror option
If -Werror is enabled and there are warnings no output file is written. Also make sure that error/warning reporting is consistent. (Thanks to Tuncer Ayaz)

asn1ct: Make formatting of errors and warnings consistent
Consistently format warning and error reports. Warning and error options from erlc now also work in asnc1ct. (thanks to Tuncer Ayaz)
Own Id: OTP-9062
Shut off some dialyzer warnings
Own Id: OTP-9063
Improvements and New Features
Crash in asn1ct_check, componentrelation_leadingattr fixed. (Thanks to Stephane Pamelard for finding the bug)
Own Id: OTP-9092
Asn1 1.6.15
Fixed Bugs and Malfunctions
The encoding of ExtensionAdditionGroup (for PER and UPER) is corrected.
Own Id: OTP-8866 Aux Id: OTP-8797, SEQ-11557
A race condition when several processes in parallel start to do encode/decode using the driver could cause an error log regarding crashing port owner process. This race is now eliminated.
Own Id: OTP-8948 Aux Id: seq11733
Asn1 1.6.14.1
Fixed Bugs and Malfunctions
Extension Addition Groups are now supported by the parser and in all backends.
Own Id: OTP-8598 Aux Id: seq-11557
Extension Addition Groups are now supported in nested types within a SEQUENCE and CHOICE as well (missed that in previous fix)

Own Id: OTP-8779
Minor corrections in the User Guide.
Own Id: OTP-8829
Asn1 1.6.14
Improvements and New Features
By default, the ASN.1 compiler is now silent in the absence of warnings or errors. The new '
verbose
' option or the '-v
' option forerlc
can be given to show extra information (for instance, about the files that are generated). (Thanks to Tuncer Ayaz.)Own Id: OTP-8565
Asn1 1.6.13
Fixed Bugs and Malfunctions
Harmless buffer overflow by one byte in asn1 and ram_file_drv.
Own Id: OTP-8451
Improvements and New Features
Cross compilation improvements and other build system improvements.
Most notable:
- Lots of cross compilation improvements. The old cross compilation support
was more or less non-existing as well as broken. Please, note that the cross
compilation support should still be considered as experimental. Also note
that old cross compilation configurations cannot be used without
modifications. For more information on cross compiling Erlang/OTP see the
$ERL_TOP/INSTALL-CROSS.md
file. - Support for staged install using
DESTDIR. The old
broken
INSTALL_PREFIX
has also been fixed. For more information see the$ERL_TOP/INSTALL.md
file. - Documentation of the
release
target of the topMakefile
. For more information see the$ERL_TOP/INSTALL.md
file. make install
now by default creates relative symbolic links instead of absolute ones. For more information see the$ERL_TOP/INSTALL.md
file.$ERL_TOP/configure --help=recursive
now works and prints help for all applications withconfigure
scripts.- Doing
make install
, ormake release
directly aftermake all
no longer triggers miscellaneous rebuilds. - Existing bootstrap system is now used when doing
make install
, ormake release
without a precedingmake all
. - The
crypto
andssl
applications use the same runtime library path when dynamically linking againstlibssl.so
andlibcrypto.so
. The runtime library search path has also been extended. - The
configure
scripts oferl_interface
andodbc
now search for thread libraries and thread library quirks the same way as ERTS do. - The
configure
script of theodbc
application now also looks for odbc libraries inlib64
andlib/64
directories when building on a 64-bit system. - The
config.h.in
file in theerl_interface
application is now automatically generated in instead of statically updated which reduces the risk ofconfigure
tests without any effect.

- Lots of cross compilation improvements. The old cross compilation support
was more or less non-existing as well as broken. Please, note that the cross
compilation support should still be considered as experimental. Also note
that old cross compilation configurations cannot be used without
modifications. For more information on cross compiling Erlang/OTP see the
Add support for prefixing macro names generated by the compiler
This is useful when multiple protocols that contains macros with identical names are included in a single module.

Asn1 1.6.11
Improvements and New Features
A new option
{n2n,TypeName}
can be used to enable generation of conversion functions from name to number and vice versa for selected ENUMERATION types. The option can be repeated many times in order to specify several types in the same file.
If theTypeName
specified does not exists or is not an ENUMERATION type, the compilation will be terminated with an error code.
Below follows an example on how to use the option from the command line witherlc
