Programming with FPC
This page attempts to give an overview of the tools that the Free Pascal
compiler puts at your disposal when you are programming.
Free Pascal comes with several command-line tools that you can use to ease
Among the tools are a source formatter, a makefile
generator, a C header translator, a unit dependency lister and even TP lex
The Free Component Library is meant as a free and portable alternative
to Delphi's VCL (Visual Component Library). It is a low-level library,
meaning that it doesn't include GUI (graphical) components. It is meant to
provide people that implement a GUI with basic routines such as stringlists,
streaming, XML routines, Database access and many more things.
It tries to provide as many Delphi-compatible components as possible, to ease
porting, but it also presents alternative components that offer different
functionality, not found in the Delphi components.
Free Pascal comes with a series of packages; mainly these are import units
for important libraries, or some tools that have been developed by the Free
There are many such packages, they range from GUI packages such as GTK and
OpenGL to database packages such as interbase and MySQL.
Most of the tools are included with the official releases of the
compiler, some of them are not, because they were developed after the compiler
The sources of these tools and units can always be downloaded from the development pages or checked out from the CVS server. Compiling should be as easy as
