Description Vitaly Novichkov 2017-01-30 21:14:41 UTC 
Just wanted to review how libresample works, but I'v got failed to build SDL and use libsamplerate statically:

I have been built libsamplerate (downloaded from here http://www.mega-nerd.com/SRC/) and built it statically (with the --enable-static=yes --enable-shared=no configure flags)

However, SDL's configure can't detect header and don't wanna use it.

Configure arguments of SDL:

./configure \
   --prefix=/home/me/project/_Libs/_build/linux \
   --includedir=/home/me/project/_Libs/_build/linux/include \
   --libdir=/home/me/project/_Libs/_build/linux/lib \
   --enable-libsamplerate=yes --disable-libsamplerate-shared

In the referred include path is the samplerate.h file.
In the referred library path is the libsamplerate.a, libsamplerate.la and pkgconfig/samplerate.pc.

libsamplerate itself built with next arguments:
./configure \
   --prefix=/home/me/project/_Libs/_build/linux \
   --includedir=/home/me/project/_Libs/_build/linux/include \
   --libdir=/home/me/project/_Libs/_build/linux/lib \
   CFLAGS=-fPIC CXXFLAGS=-fPIC --enable-static=yes --enable-shared=no

In result:
...
checking audio/audiolib.h usability... no
checking audio/audiolib.h presence... no
checking for audio/audiolib.h... no
...
and then:
Using libsamplerate : NO

Okay, adding next global variables are fixing trouble:

export CFLAGS='-I/home/me/project/_Libs/_build/linux/include'
export LDFLAGS='-L/home/me/project/_Libs/_build/linux/lib'

and SDL has been successfully linked with static build of libsamplerate (which installed into the custom prefix)
