GNU Libtool

GNU Libtool is a software development tool, part of the GNU build system, consisting of a shell script created to address the software portability problem when compiling shared libraries from source code. It hides the differences between computing platforms for the commands which compile shared libraries. It provides a command-line interface that is identical across platforms and it executes the platform's native commands, allowing software authors to offer build support for their code across many diverse platforms such as Linux, BSD variants, Windows (via Cygwin), HP-UX, Solaris (including on SPARC processors), AIX, and IRIX.
