compilation failure on PPC without AltiVec

[eternalsword@…]

I'll attach full logs of running configure and make in a reply. I've got svn revision 26606 on a fully up to date debian testing. I'm using the debian-multimedia repository for some of the libraries. I built x264 against whatever the current git head was two days ago.

I have tried building with --disable-altivec with no difference. I have tried building with --enable-altivec and it builds successfully but get the following error when I try to run it.

MPlayer dev-SVN-r26606-4.2.3 (C) 2000-2008 MPlayer Team
AltiVec not found

MPlayer interrupted by signal 4 in module: demux_open

• MPlayer crashed by an 'Illegal Instruction'. It usually happens when you run it on a CPU different than the one it was compiled/optimized for. Verify this!
• MPlayer crashed by bad usage of CPU/FPU/RAM. Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
• MPlayer crashed. This shouldn't happen. It can be a bug in the MPlayer code _or_ in your drivers _or_ in your gcc version. If you think it's MPlayer's fault, please read DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and won't help unless you provide this information when reporting a possible bug.

I tried using the mplayer made available by the debian-multimedia repository and that one worked. Here's the mplayer version output: MPlayer dev-SVN-r25315

diff file used by debian-multimedia control system

[eternalsword@…]

I'm including this because when I tried to build the working revision used by debian-multimedia, the build failed (though at a different point, see error below). So their diff file is probably a good starting point for figuring out what's wrong.

The error I got when building debian-multimedia's working revision was

make -C libswscale

I'll try to sort through the diff file to see what might be helpful.

Just to clarify, I have not yet tried applying debian-multimedia's patch, so I have not yet been able to build a working mplayer myself to this point.

[diego@…]

I just fixed the compilation failure. There is still a linking issue left, but I have already analyzed it and will commit a fix shortly.

[eternalsword@…]

unfortunately compilation still does not work for me. I'll post updated logs for revision 26632

problem fixed as of revision 26642

[eternalsword@…]

Unfortunately, I spoke too soon. The mplayer that was working was the one from debian-multimedia which I had forgotten to remove. So mplayer built successfully, but I had the MPlayer crashed by an 'Illegal Instruction' error when trying to run it.

[eternalsword@…]

the configure from r26643 now forces altivec even when the --disable-altivec flag is provided.

diff between mplayer libmpeg2 and ​svn://svn.videolan.org/libmpeg2/trunk

generated by using: diff -u /build/mplayer/libmpeg2 /build/libmpeg2/libmpeg2

[eternalsword@…]

forgot to mention that I am attaching this because I was able to successfully compile and run mpeg2dec from this version of libmpeg2

[eternalsword@…]

I was able to build and run r26676 by doing the following, I'm guessing because of the updates to libmpeg2.

1)Run configure
2)Edit config.h to change
#define HAVE_ALTIVEC 1 -> #undef HAVE_ALTIVEC
#define ENABLE_ALTIVEC 1 -> #define ENABLE_ALTIVEC 0
#define HAVE_ALTIVEC_H 1 -> #undef HAVE_ALTIVEC_H
3)Edit config.mak to remove all -maltivec -mabi=altivec occurrences
4)make and make install

I'm guessing undoing the revision 26642 changeset to the configure file will fix having to change the config.h and config.mak files, since as of that revision, I could no longer even manually disable altivec via --disable-altivec

[diego@…]

Next try, should really be fixed now...
