Just tried compiling "media-video/mkvtoolnix-1.5.5". It fails, complaining that libmatroska can't be found, when it's already definitely installed on the system. During it's configure: ... checking size of long long... 8 checking for posix_fadvise... yes checking for iconv... yes checking for iconv declaration... extern size_t iconv (iconv_t cd, char * *inbuf, size_t *inbytesleft, char * *outbuf, size_t *outbytesleft); checking for nl_langinfo... yes checking for ogg_sync_init in -logg... yes checking ogg/ogg.h usability... yes checking ogg/ogg.h presence... yes checking for ogg/ogg.h... yes checking for vorbis_synthesis_init in -lvorbis... yes checking vorbis/codec.h usability... yes checking vorbis/codec.h presence... yes checking for vorbis/codec.h... yes checking for FLAC__seekable_stream_decoder_new in -lFLAC... yes checking for FLAC__StreamMetadata_StreamInfo.sample_rate... yes checking for FLAC__seekable_stream_decoder_skip_single_frame in -lFLAC... yes checking for libebml version >= 0.7.3... yes checking if linking against libebml requires -DEBML_DLL... no checking for libmatroska version >= 0.7.5... yes checking if linking against libmatroska requires -DMATROSKA_DLL... not found *** libmatroska was not found.
Created attachment 76141 [details] Log file from the failed configure run. Added this as instructed by the emerge failure code.
Try rebuilding libmatroska, as it seems to have been linked against an old version. If still an issue, reopen with emerge info output.
had the same problem here. worked after re-emerging libmatroska
