Here is the relevant portion of 'ffbuild/config.log' for Opus. Please
can some experienced person help out with this?
I can tell that the linker flag "-lm" seems to be missing.
You information is a bit sparse. Can you show us your complete
configure command line as well please?
../ffmpeg/configure --enable-gpl --enable-version3 --disable-podpages
--enable-gnutls
--enable-libx264 --enable-gmp --enable-libopus --enable-libmp3lame
--enable-libtheora
--enable-libvorbis
And also the content of opus.pc
# Opus codec reference implementation pkg-config file
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
Name: opus
Description: Opus IETF audio codec (floating-point, custom modes build)
URL: https://opus-codec.org/
Version: 1.3
Requires:
Conflicts:
Libs: -L${libdir} -lopus
Libs.private: -lm
Cflags: -I${includedir}/opus
(I hope you didn't rename it).
The log I posted was generated on my initial attempt to build, before I
decided to start renaming things. Since I only prepended 'lib', it is
easy enough to restore the original names.
Possibly, you only built a static libopus,
Yes. I built all libs static only, because I am building only the static
version of ffmpeg. No problem for me to go back and rebuild the libs,
enabling the dynamic builds also.
but pkg-config is being
called for synamic linking (and thereby omits Libs.private).
(A quick workaround may be to add "--extra-ldflags=-lm".)
I can try that. Thank you, Moritz, I seriously appreciate your help.
Jeff
