FreeBASIC - A multi-platform BASIC Compiler Copyright (C) 2004-2012 The FreeBASIC development team. Official site: http://www.freebasic.net/ Forum: http://www.freebasic.net/forum/ Online manual: http://www.freebasic.net/wiki/DocToc fbc project page: http://www.sourceforge.net/projects/fbc/ IRC channel: ##freebasic at irc.freenode.net FreeBASIC consists of fbc (the command line compiler), the runtime libraries (included into FB programs by fbc), compiler tools (assembler, linker) used by fbc, and headers and bindings for third-party libraries. Documentation of language features, compiler options and many other details is available in the FB manual. For help & support, visit the FB forum! Features: http://www.freebasic.net/wiki/CompilerFeatures Requirements: http://www.freebasic.net/wiki/CompilerRequirements o Installation & usage The fbc project provides installers and/or archives for multiple operating systems. After installing or extracting FreeBASIC, fbc[.exe] is ready for use. fbc is typically used from the command line, via build-systems such as makefiles, or through IDEs. When run from a command prompt, without command line arguments, it shows a list of options. In order to compile a .bas program into an executable, the file name must be passed on fbc's command line: fbc example.bas this should create the output executable next to the .bas file. If you are using an IDE or text editor, it is usually possible to configure it to use fbc[.exe] to compile FB programs. Please look at the IDE's configuration options or documentation. o Licensing The FreeBASIC compiler (fbc) is licensed under the GNU GPLv2 or later. The FreeBASIC runtime library, in both normal (libfb) and thread-safe (libfbmt) versions, is licensed under the GNU LGPLv2 or later, with this extension to allow linking to it statically: As a special exception, the copyright holders of this library give you permission to link this library with independent modules to produce an executable, regardless of the license terms of these independent modules, and to copy and distribute the resulting executable under terms of your choice, provided that you also meet, for each linked independent module, the terms and conditions of the license of that module. An independent module is a module which is not derived from or based on this library. If you modify this library, you may extend this exception to your version of the library, but you are not obligated to do so. If you do not wish to do so, delete this exception statement from your version. The FreeBASIC graphics library (libfbgfx) is licensed under the GNU LGPLv2 or later. The FreeBASIC documentation is licensed under the GNU FDL. Dependencies on third-party libraries: The FreeBASIC runtime library uses LibFFI to implement the Threadcall functionality. This means that, by default, FreeBASIC programs will be linked against LibFFI when using Threadcall. LibFFI is released under the MIT/Expat license, see doc/LICENSE.libffi. By default, FreeBASIC programs are linked against various system and/or support libraries, depending on the platform. Those include the DJGPP libraries used by FreeBASIC for DOS and the MinGW/GCC libraries used by FreeBASIC for Windows. o Included/used third-party tools and libraries: - DJGPP http://www.delorie.com/ - GCC http://gcc.gnu.org/ - GNU binutils http://www.gnu.org/software/binutils/ - GNU debugger http://www.gnu.org/software/gdb/ - GoRC http://www.godevtool.com/ - LibFFI http://sourceware.org/libffi/ - MinGW http://www.mingw.org/ - OpenXDK http://www.openxdk.org/ - TDM-GCC http://tdm-gcc.tdragon.net/ o Credits Project members: - Andre Victor T.
