Thank you very much. Either your alsa-lib version is too old in the build environment (you're doing cross-compilation, right?) or the alsa-lib pkg-config file doesn't exist where pkg-config is looking for it. The pkg-config file for alsa-lib has name alsa.pc. Check that the file exists in the right directory. On my system it's at /usr/lib/x86_64-linux-gnu/pkgconfig/alsa.pc. If I would have compiled and installed alsa-lib myself from source, it would probably be at /usr/local/lib/pkgconfig/alsa.pc. If you're cross-compiling, the right directory may be something else. -- Tanu
