Created attachment 555918 [details] build.log I'm trying to compile media-plugins/gst-plugins-libav with USE=libav to fix another problem (#654628) which prevent ANY update on my system. Compilation fails with errors such as In file included from src/libavutil/internal.h:169:0, from src/libavutil/common.h:467, from src/libavutil/avutil.h:296, from src/libavutil/samplefmt.h:24, from src/libavcodec/avcodec.h:31, from src/libavformat/avformat.h:319, from src/libavformat/amr.c:30: src/libavutil/libm.h:458:41: error: static declaration of ‘trunc’ follows non-static declaration static av_always_inline av_const double trunc(double x) ^~~~~ In file included from /usr/include/features.h:428:0, from /usr/include/bits/libc-header-start.h:33, from /usr/include/stdint.h:26, from /usr/lib/gcc/x86_64-pc-linux-gnu/7.3.0/include/stdint.h:9, from src/libavutil/channel_layout.h:25, from src/libavformat/amr.c:29: /usr/include/bits/mathcalls.h:302:1: note: previous declaration of ‘trunc’ was here __MATHCALLX (trunc,, (_Mdouble_ __x), (__const__)); ^ In file included from src/libavutil/internal.h:169:0, from src/libavutil/common.h:467, from src/libavutil/avutil.h:296, from src/libavutil/samplefmt.h:24, from src/libavcodec/avcodec.h:31, from src/libavformat/avformat.h:319, from src/libavformat/amr.c:30: src/libavutil/libm.h:465:40: error: static declaration of ‘truncf’ follows non-static declaration static av_always_inline av_const float truncf(float x) ^~~~~~ In file included from src/libavutil/common.h:36:0, from src/libavutil/avutil.h:296, from src/libavutil/samplefmt.h:24, from src/libavcodec/avcodec.h:31, from src/libavformat/avformat.h:319, from src/libavformat/amr.c:30: /usr/include/bits/mathcalls.h:302:1: note: previous declaration of ‘truncf’ was here __MATHCALLX (trunc,, (_Mdouble_ __x), (__const__));
Please show 'emerge --info'. gst-libs/ext/libav/libavutil/libm.h declares the relevant functions conditionally based on HAVE_* macros. Example: #if !HAVE_TRUNC static av_always_inline av_const double trunc(double x) { return (x > 0) ? floor(x) : ceil(x); } #endif /* HAVE_TRUNC */ HAVE_* macros which are set in gst-libs/ext/libav/configure. You need to find why they were not detected for you.
You might also check media-plugins/gst-plugins-libav-1.14.4.3.4.5 which requires patch from bug #666674.
I'm kinda lost. It seems HAVE_TRUNC is not defined (though it really seems that my sys-libs/glibc-2.27-r6 provides it). : berlioz /tmp/portage/media-plugins/gst-plugins-libav-1.14.2 # ack HAVE_TRUNC -w work/gst-libav-1.14.2-abi_x86_64.amd64/gst-libs/ext/libav/config.asm 261:%define HAVE_TRUNC 0 work/gst-libav-1.14.2-abi_x86_64.amd64/gst-libs/ext/libav/config.h 277:#define HAVE_TRUNC 0 work/gst-libav-1.14.2-abi_x86_64.amd64/gst-libs/ext/libav/ffbuild/config.mak 409:!HAVE_TRUNC=yes work/gst-libav-1.14.2/gst-libs/ext/libav/libavutil/libm.h 457:#if !HAVE_TRUNC 462:#endif /* HAVE_TRUNC */ It took me some time to understand that libav config log is not in the usual /tmp/portage/media-plugins/gst-plugins-libav-1.14.2/temp but rather in /tmp/portage/media-plugins/gst-plugins-libav-1.14.2/work/gst-libav-1.14.2-abi_x86_64.amd64/gst-libs/ext/libav/ffbuild/config.log But i dont understand why HAVE_TRUNC is set to false. I have a pretty boring/common x86_64-pc-linux-gnu-7.3.0.

You have again attached a build log, not config.log. Please try media-plugins/gst-plugins-libav-1.14.4.3.4.5 which is now in the tree. Also please show full 'emerge --info'.
Oops, sorry for the build.log, indeed. I've just tried media-plugins/gst-plugins-libav-1.14.4.3.4.5:1.0/1.0::gentoo, which fails with the same errors.
