[erlang-patches] Crypto Compile Problem on x86_64 OTP-R11B

[Daniel Schutte]

I have seen a few postings on the web regarding this error - specifically in 
the e-jabberd lists.  The solution is given as compiling with gcc 4.0 instead 
of 4.1.
Erlang Compiles fine, it's just the crypto module that is incomplete - more 
specifically the driver.

in the make file the following appears:

/usr/bin/ld: /usr/lib64/libcrypto.a(x86_64cpuid.o): relocation R_X86_64_PC32 
against `OPENSSL_cpuid_setup' can not be used when making a shared object; 
recompile with -fPIC
/usr/bin/ld: final link failed: Bad value
collect2: ld returned 1 exit status
make[4]: *** [../priv/lib/x86_64-unknown-linux-gnu/crypto_drv.so] Error 1
make[3]: *** [opt] Error 2

============================
Tracing this you get this command that failed

[olympus@REDACTED c_src]$ 
gcc -shared  -o ../priv/lib/x86_64-unknown-linux-gnu/crypto_drv.so ../priv/obj/x86_64-unknown-linux-gnu/crypto_drv.o  /usr/lib64/libcrypto.a

recompile with -fPIC
/usr/bin/ld: final link failed: Bad value

============================
else you will find it doing this: 

1> crypto:start().
exec: 1: ok
2> crypto_drv: not found

============================= Solution / Fix ===

Right or wrong this fixed the problem

after 

./configure
make

go to the directory  %ERL_TOP%/lib/crypto/c_src
issue the command:

gcc -shared  -o ../priv/lib/x86_64-unknown-linux-gnu/crypto_drv.so ../priv/obj/x86_64-unknown-linux-gnu/crypto_drv.o  /usr/lib64/libcrypto.so

now do: make install

crypto:start().
