Compiling ffmpeg leads to this error: ERROR: aom >= 1.0.0 not found using pkg-config media-libs/libaom-1.0.0 is installed. See the attached logs for gentoo specific information. Further investigation leads to this on the libaom side: ``` % pkg-config --print-provides aom aom = 0.1.0 % cat test.c #include <stdio.h> #include <aom/aom_codec.h> int main() { int v = aom_codec_version(); printf("%d,%d,%d\n", AOM_VERSION_MAJOR(v), AOM_VERSION_MINOR(v), AOM_VERSION_PATCH(v)); } % gcc -laom -lm -lpthread test.c -o test-aom % ./test-aom 0,1,0 ``` FFmpeg configure defines this line: ``` enabled libaom && require_pkg_config libaom "aom >= 1.0.0" aom/aom_codec.h aom_codec_version ``` I'm not sure, where the bug is.

The problem is definitely on the libaom side. I will adjust the title. I searched a bit more in the aom source code. The version is set per cmake with build/cmake/version.cmake. This script first tries to extract the version out of the git tags. This would work, because the git tree is correctly tagged. However, in the source archive used by the libaom ebuild is no git tree, so it extracts as second step the version with another script (build/cmake/version.pl) out of the CHANGELOG file. This file is incorrect within the 1.0.0 release (see here: https://aomedia.googlesource.com/aom/+/v1.0.0/CHANGELOG). So the wrong v0.1.0 version is extracted and used. I tried to fix it. One way seems to be to create an own "config/aom_version.h" file. This would be taken by cmake. Far more easy (but kind of dirty) is the following patch.
