[erlang-bugs] R16A : 2 issues in WX driver compilation

[PAILLEAU Eric]

Hello Patrick and Dan,

I uninstalled everything related to wx of my system with rpm,
then I removed all manually compiled wx 2.9 libraries.
Then I installed again wx 2.8.10 packages of my system with rpm.

#) configure, make and install for R15B03 is OK :

But I encountered a little issue when launching observer :
=ERROR REPORT==== 19-Feb-2013::21:43:20 ===
ERROR: Could not find 'wxe_driver.so' in:
/usr/local/lib/erlang/lib/wx-1.0/priv

certainly due to my former install of R16A (without wx) there was still
an empty wx-1.0 directory and then erl try to use the most
highest driver version.

/usr/local/lib/erlang/lib/wx-0.99.1/priv/wxe_driver.so
/usr/local/lib/erlang/lib/wx-0.99.2/priv/wxe_driver.so
/usr/local/lib/erlang/lib/wx-1.0/priv/                  <-- empty

I suppose that install *should not create wx directories when wx is not
enabled*, or erl to use the highest non empty priv directory of wx...

By removing this directory everything fine.
observer works.


#) Now R16A :
WX is OK but compilation fails on :
obj/i686-pc-linux-gnu/opt/smp/unix_efile.o: In function `efile_fallocate':
/home/eric/otp_src_R16A/erts/emulator/drivers/unix/unix_efile.c:1013:
undefined reference to `fallocate64'

As I told before my libc does not export fallocate64,
see my former mail on such subject.

=================================================================
The whole R16A compile, except WX...

So the problem is my _FILE_OFFSET_BITS=32 overriding ! ...

Maybe you can understand where the problem is and do a fix
in order to let use of 32 bit offset if needed .

Best regards.
