The purpose of libfixposix is to offer replacements for parts of POSIX whose behaviour is inconsistent across *NIX flavours.

• Compilation

If you've downloaded this library through git, you'll first need to generate the ./configure script; in order to do that you need to have at least autoconf-2.67, automake-1.10, libtool-2.2.6b, pkg-config and check (for the test suite: see http://check.sf.net) then run this inside the top directory:

autoreconf -i -f

For best results use a dedicated build directory instead of running the configure script directly in the source tree:

mkdir build ; cd build ../libfixposix/configure make make install

On Linux, you might need to run «ldconfig» as superuser after installing, otherwise the *nix linker won't be able to find the library

• Installation through distro repositories

For a certain number of Linux distributions, there are officially supported repositories. You can find the instructions to configure the binary repository at https://software.opensuse.org/download.html?project=home:sionescu&package=libfixposix. Just click on your distribution, if present.

http://article.gmane.org/gmane.lisp.iolib.devel/422 also has a set of older instructions about installing on Debian-based distros.
