Hi, Buildd machine's CPU is PPC970MP, so it supports AltiVec.
ppc64 buildd nodes add no additional build option, so, ppc64 port fundamentally does not support AltiVec except intentionally being added AltiVec option by package maintainer in source package. The source package of ffmpeg seems to add AltiVec option intentionally, so it was compiled as AltiVec enabled (-maltivec -mabi=altivec). https://buildd.debian.org/status/fetch.php?pkg=ffmpeg&arch=ppc64&ver=7%3A3.0.2-4&stamp=1466611924 *** standard *** install prefix /usr source path /«PKGBUILDDIR» C compiler cc C library glibc ARCH ppc (generic) version string suffix 4 big-endian yes runtime cpu detection yes AltiVec enabled yes VSX enabled no POWER8 enabled no PPC 4xx optimizations no dcbzl available yes debug symbols yes strip symbols no optimize for size no optimizations yes static yes shared yes postprocessing support yes new filter support yes network support yes threading support pthreads safe bitstream reader yes SDL support yes opencl enabled no texi2html enabled no perl enabled yes pod2man enabled yes makeinfo enabled yes makeinfo supports HTML yes (snip) cc -I. -Isrc/ -Wdate-time -D_FORTIFY_SOURCE=2 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -D_ISOC99_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_POSIX_C_SOURCE=200112 -D_XOPEN_SOURCE=600 -DPIC -DZLIB_CONST -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -fno-strict-overflow -fstack-protector-all -std=c99 -fomit-frame-pointer -fPIC -maltivec -mabi=altivec -pthread -I/usr/include/p11-kit-1 -I/usr/include/harfbuzz -I/usr/include/glib-2.0 -I/usr/lib/powerpc64-linux-gnu/glib-2.0/include -I/usr/include/freetype2 -I/usr/include/fribidi -I/usr/include/freetype2 -I/usr/include/bs2b -I/usr/include/freetype2 -I/usr/include/freetype2 -I/usr/include/fribidi -I/usr/include/opus -D_REENTRANT -I/usr/include/p11-kit-1 -I/usr/include/schroedinger-1.0 -I/usr/include/orc-0.4 -D_GNU_SOURCE=1 -D_REENTRANT -I/usr/include/SDL -g -Wdeclaration-after-statement -Wall -Wdisabled-optimization -Wpointer-arith -Wredundant-decls -Wwrite-strings -Wtype-limits -Wundef -Wmissing-prototypes -Wno-pointer-to-int-cast -Wstrict-prototypes -Wempty-body -Wno-parentheses -Wno-switch -Wno-format-zero-length -Wno-pointer-sign -O3 -fno-math-errno -fno-signed-zeros -fno-tree-vectorize -Werror=format-security -Werror=implicit-function-declaration -Werror=missing-prototypes -Werror=return-type -Werror=vla -Wformat -fdiagnostics-color=auto -Wno-maybe-uninitialized -MMD -MF tools/qt-faststart.d -MT tools/qt-faststart.o -c -o tools/qt-faststart.o src/tools/qt-faststart.c Mathieu Malaterre wrote: > Hi, > > On Tue, Jun 21, 2016 at 1:57 PM, Hiroyuki Yamamoto <yama1...@gmail.com> wrote: >> -----BEGIN PGP SIGNED MESSAGE----- >> Hash: SHA256 >> >> Hi, Mathieu, >> >> Mathieu Malaterre wrote: >>> It looks like ffmpeg fails to build on ppc64 due to a timeout: >>> >>> https://buildd.debian.org/status/fetch.php?pkg=ffmpeg&arch=ppc64&ver=7%3A3.0.2-4&stamp=1465651053 >>> >>> gb ffmpeg_7:3.0.2-4 . ppc64 >>> >>> comments ? >>> >>> >> >> To be certain, I will give back ffmpeg_7:3.0.2-4 after gcc-6_6.1.1-7 has >> been built, >> but ffmpeg has failed to build on ppc64 from changing to ver. 3.0 by same >> point: >> >> TEST ffprobe_xml >> /?PKGBUILDDIR?/tests/fate-run.sh fate-ffprobe_xml "" "" >> "/?PKGBUILDDIR?/debian/standard" 'run ffprobe -show_streams -show_packets >> -show_format -show_frames -bitexact tests/data/ffprobe-test.nut -of xml' '' >> '' '' '1' '' '' '' '' '' '' '' '' >> /?PKGBUILDDIR?/debian/standard/ffprobe -show_streams -show_packets >> -show_format -show_frames -bitexact tests/data/ffprobe-test.nut -of xml >> make[2]: Target 'check' not remade because of errors. >> make[2]: Leaving directory '/?PKGBUILDDIR?/debian/standard' >> dh_auto_test: make -j1 check -k returned exit code 2 >> debian/rules:225: recipe for target 'override_dh_auto_test-arch' failed >> make[1]: *** [override_dh_auto_test-arch] Error 2 >> make[1]: Leaving directory '/?PKGBUILDDIR?' >> debian/rules:185: recipe for target 'build-arch' failed >> make: *** [build-arch] Error 2 >> dpkg-buildpackage: error: debian/rules build-arch gave error exit status 2 > > Indeed.
