libSystem is the most essential library within DeforaOS, with the aim to become a complete C runtime (thus obsoleting the libc and replacing its API). Regardless of its progress in this regard, libSystem is intended to be portable and work on any system, using any POSIX-compliant runtime provided instead.

With GCC, this should be enough:

$ make

To install libSystem in a dedicated directory, like /path/to/libSystem:

$ make PREFIX="/path/to/libSystem" install

Part of libSystem's API can also be accessed from within the Python programming language. This binding is not compiled or installed by default though. After installing libSystem as documented above, the Python interface can be built and installed as follows:

$ (cd src/python && make install)

Likewise, an alternate installation directory may be specified:

$ (cd src/python && make PREFIX="/path/to/libSystem" install)
