Installing Speex is as easy as: 1. Using the autotools build system: % ./configure [--prefix=] % make % make install Note that if you are using the code from Git, you will need to run "autogen.sh" and then "configure". 2. Using the Meson build system: % meson setup builddir [--prefix=] [-Doption=value] % meson configure builddir (to see configuration options and default values) % ninja -C builddir % ninja -C builddir install The Meson build has been tested for Linux, macOS, iOS, Android and Windows (MingW + MSVC) targets, both native builds and cross builds. See meson_options.txt for a list of available configuration options. More information on how to install Meson and use it can be found here: https://mesonbuild.com/Quick-guide.html
