Free Pascal supports the creation of shared libraries on several operating systems. The following table (table (12.1)) indicates which operating systems support the creation of shared libraries.
|Operating systems||Library extension||Library prefix|
The library prefix column indicates how the names of the libraries are resolved and created. For example, under linux, the library name will alwaus have the lib prefix when it is created. So if you create a library called mylib, under linux, this will result in the libmylib.so. Furthermore, when importing routines from shared libraries, it is not necessary to give the library prefix or the filename extension.
In the following sections we discuss how to create a library, and how to use these libraries in programs.
