Libtool provides a small library, called libltdl, that aims at hiding the various difficulties of dlopening libraries from programmers. It consists of a few headers and small C source files that can be distributed with applications that need dlopening functionality. On some platforms, whose dynamic linkers are too limited for a simple implementation of libltdl services, it requires GNU DLD, or it will only emulate dynamic linking with libtool’s dlpreopening mechanism.
libltdl supports currently the following dynamic linking mechanisms:
dlopen (POSIX compliant systems, GNU/Linux, etc.)
LoadLibrary (Win16 and Win32)
NSLinkModule (Darwin and Mac OS X)
