[CinCVS] A vision of Cinelerra v3 (hopefully)
Hi,
Just following up on some discussion on IRC about CinV3 options, here's
a hypothetical example based on the concept of 'libcinelerra', the main
video editing engine, on top of which any gui is very thin and very
cleanly separated.
Cheers
David

No, probably not, but I think that's ok. --with-pic is kind of ugly. You can build if that option is not specified, right? Does removing both --enable-mmx and --with-pic build for you? Does it auto detect mmx and build with it anyway in that case? ffmpeg/libavcodec/.libs/libavcodec.a(fdct_mmx.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC ffmpeg/libavcodec/.libs/libavcodec.a(fdct_mmx.o): could not read symbols: Bad value did not look into it but must be a change after my patch from earlier this year. This it the error I see, but it's because ffmpeg does not build with PIC, even though the rest of the build does. An additional problem may be that there was trouble building the mmx portion of ffmpeg some time ago with PIC. I need to verify of that is why we've had so much trouble with it. I noticed from your older emails, j, that you were not using internal ffmpeg. I think that is why this was not noticed before. If the build was using external ffmpeg, then I would not expect to see the error you posted. On 2007-08-19 10:50, Graham Evans wrote: ...

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.

Re: [CinCVS] Re: [Cinelerra-commits] r1007 - in trunk/hvirtual: . libmpeg3/video
I was running into the same error, until I disabled mmx. I finally was able to compile Cinelerra with AMD64 ubuntu, for the first time ever, before I always had to muddy up my repositories with stuff from Debian unstable that made upgrading a pain and installing certain software from repositories difficult. Does anyone know if MMX optimizations will make enough of a performance difference that I should try recompiling with the fix. I will check my logs to see if I used --with-pic, I think that I did. for what its worth svn up ./autogen.sh ./configure --enable-mmx --with-pic make does *not* work on my amd 64 / ubuntu box right now. ffmpeg/libavcodec/.libs/libavcodec.a(fdct_mmx.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC ffmpeg/libavcodec/.libs/libavcodec.a(fdct_mmx.o): could not read symbols: Bad value did not look into it but must be a change after my patch from earlier this year. j ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra

Thanks Graham, I suspect no one knew the full impact of this change. I think it will fix my build problem also. Does anyone have a system that builds without -fPIC on a 64 bit platform (either amd64 or Intel?) I think that is the only case that may break with the change. I don't see any results for this case, although there are some comments that fPIC should not be needed in all cases. -- Kevin ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
