There are detailed instructions for building libsamplerate on Win32 in the file docs/win32.md.

Building on macOS should be the same as building it on any other Unix platform.

To compile libsamplerate on platforms which have a Bourne compatible shell, an ANSI C compiler and a make utility should require no more that the following three commands:

autoreconf -vif
./configure
make
make install

There is a new CMake-based build system available:

mkdir build
cd build
cmake ..
make

• Use cmake -DCMAKE_BUILD_TYPE=Release .. to make a release build.
• Use cmake -DBUILD_SHARED_LIBS=ON .. to build a shared library.
