Well, this has been a long and somewhat painful investigation. :) I can answer why the original patch is not or should not be committed as is, Graham. It breaks 32 bit intel/amd platform builds. I've extended it and will commit a change that should work on all intel/amd 32 and 64 bit systems. Please let me know if anyone sees trouble with builds afterwards. The short version, is that ffmpeg/libavcodec in our tree needs -prefer-non-pic for 32 bit platforms, but not 64 bit (on the platforms I tested and for the people who reported in this thread.) If you disable PIC completely on 64 bit platforms, you will normally fail to link, either the ffmpeg portion or a higher level library. On 32bit, it's a little more complicated. ffmpeg/avcodec builds with PIC, but selectively. The mpegvideo_mmx file can not build with PIC, else it will not have enough registers to compile successfully. The -prefer-non-pic causes ffmpeg to build some files with PIC and some without, mpegvideo_mmx being built without PIC. I suspect you can break the build by overriding all this with one of --with-pic or --without-pic on the top level configure.

Hi Kevin Let me know if I have gone wrong but I think I have the neccessary skills to answer your questions. Note all the following tests are performed on cinelerra CV svn 1017 with Hermann's patch as attached to my last email. This builds and runs succesfully and performs well as far as I can see. Firstly - I am guessing this is a typical gcc command for cinelerra: gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I./.. -DHAVE_MMX -DUSE_MMX -DX86_CPU -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -g -O2 -MT idct.lo -MD -MP -MF .deps/idct.Tpo -c idct.c -fPIC -DPIC -o .libs/idct.o I'm not sure if that includes the PIC flag you were looking for. Also, if you have a build log, would you show me the compile options of mpegvideo_mmx when it builds? (If it builds... It will only build if mmx is specified or auto detected as true. I'd like to know if it does not auto detect mmx also.) MMX is detected I suppose from this: 'CPU_CFLAGS='-DHAVE_MMX -DUSE_MMX -DX86_CPU ' Compile options for mpegvideo_mmx: if /bin/sh ../../../../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I../../../..-D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -DHAVE_MMX -DUSE_MMX -DX86_CPU -DHAVE_MMX -msse -DHAVE_BUILTIN_VECTOR -O3 -D_GNU_SOURCE -DHAVE_AV_CONFIG_H -I./../.. -I../.. -g -O2 -MT mpegvideo_mmx.lo -MD -MP -MF .deps/mpegvideo_mmx.Tpo -c -o mpegvideo_mmx.lo mpegvideo_mmx.c; \ then mv -f .deps/mpegvideo_mmx.Tpo .deps/mpegvideo_mmx.Plo; else rm -f .deps/mpegvideo_mmx.Tpo; exit 1; fi gcc -DHAVE_CONFIG_H -I. -I. -I../../../.. -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -DHAVE_MMX -DUSE_MMX -DX86_CPU -DHAVE_MMX -msse -DHAVE_BUILTIN_VECTOR -O3 -D_GNU_SOURCE -DHAVE_AV_CONFIG_H -I./../.. -I../.. -g -O2 -MT mpegvideo_mmx.lo -MD -MP -MF .deps/mpegvideo_mmx.Tpo -c mpegvideo_mmx.c -fPIC -DPIC -o .libs/mpegvideo_mmx.o Thanks all, And a quick comment about ffmpeg external option - my understanding is that ffmpeg versions since about August 2006 are incompatible with the current cinelerra. There is already a bug filed about that. I think the recommended way to build cinelerra at present is to somehow get internal ffmpeg working. On debian etch + going to a version of ffmpeg early enough to get a successful build breaks dependencies in lots of unrelated deb packages.

I faintly recall that I have even encouraged j not to touch USEMMX in ffmpeg, because it has a different meaning/purpose there. What's your problem? I suspect it is that MMX is now enabled in ffpmeg where it was not before, and fPIC is not set properly for the ffpmeg build. I am seeing an fPIC error while trying to link mpegvideo_mmx.o in ffmpeg/libavcodec. The failure is because the mmx .o file is built without -fPIC. Note that the patch adds a x86_64 cpu target to configure.in which auto detects mmx, it seems. This enables mmx for all sublibs on x86_64, which was not the case before. There is a new USEMMX32 define for non-64 bit targets... Also, the configure for 3dnow was left off the x86_64 arch block in configure.in, was this intentional? Anyway, we should be able to enable mmx across the board on x86_64, I would think. I'll look in to why ffmpeg doesn't configure the same as other parts of the build with respect to -fPIC. I noticed there was a change to it's -fPIC preference also. This may relate to the trouble. Do you recall what platform j was using? I assume the patch fixed the build on his platform while breaking SUSE. I can build if I pass --disable-mmx to configure, skipping the trouble files in ffmpeg. -- Kevin ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

I faintly recall that I have even encouraged j not to touch USEMMX in ffmpeg, because it has a different meaning/purpose there. What's your problem? I suspect it is that MMX is now enabled in ffpmeg where it was not before, and fPIC is not set properly for the ffpmeg build. I am seeing an fPIC error while trying to link mpegvideo_mmx.o in ffmpeg/libavcodec. The failure is because the mmx .o file is built without -fPIC. Note that the patch adds a x86_64 cpu target to configure.in which auto detects mmx, it seems. This enables mmx for all sublibs on x86_64, which was not the case before. There is a new USEMMX32 define for non-64 bit targets... Also, the configure for 3dnow was left off the x86_64 arch block in configure.in, was this intentional? Anyway, we should be able to enable mmx across the board on x86_64, I would think. I'll look in to why ffmpeg doesn't configure the same as other parts of the build with respect to -fPIC. I noticed there was a change to it's -fPIC preference also. This may relate to the trouble. Do you recall what platform j was using? I assume the patch fixed the build on his platform while breaking SUSE. Sorry, I can't remember the details, not even my own arguments. Please search in ML archives. I'd appreciate if you could go over this issue again. I don't have the hardware to help. Let's hope that j is listening and can give feedback. -- Hannes ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
