Howto specify library location when compiling

rated 0 times [ 0] [ 0] / answers: 1 / hits: 1578 / 1 Year ago, wed, december 28, 2022, 8:58:25

How do I specify the location of a library when running ./configure ?

I have searched around and think the answer lies in setting LDFLAGS and CPPFLAGS, but I,m not sure how to do it.

Specifically, I have compiled libx264 and I now want to compile libav and enable libx264 support, but dont know how to point ./configure to my libx264 include and lib folders.

Thanks.

Thanks for the pointer. I did more reading and discovered how to do this. The solution is two-fold.

Compile x264 with '--enable-shared' as well as '--enable-static'. Without specifying '--enable-shared', the library was never found.

Specify the location of the 'lib' and 'include' files generated by the x264 make process like this :-

./configure --extra-ldflags="-L/path/to/extra/lib" --extra-cflags="-I/path/to/extra/includes" --enable-x264 ..etc ..etc

I have now successfully compiled libav, with x264 support, and have the following binaries :-

avconv, avplay, avprobe, avserver, ffmpeg.

Off course I am sure if I had just installed libav using apt-get I would have saved myself a lot of trouble, but as this was a learning process I think I have learned a lot.
