Open Source BASIC Compilers

Open-source, free, multi-platform BASIC compiler, with syntax similar MS-QuickBASIC (including the GFX statements), that adds new features such as pointers, unsigned data types, inline assembly, a pre-processor and many others.

GCBASIC is an open-source BASIC compiler for 8 bit Microchip PIC, Atmel AVR legacy, AVRDx and LGT microcontrollers. See https://ko-fi.com/post/The-Story-of-GCBASIC-Making-Microcontroller-Progr-D1D319SJ72 for story of GCBASIC. This is a continuous release project. The latest release is always available. This will give you the most complete development toolchain to create and program 8-bit PIC, AVR and LGT microcontrollers. We have added new capabilities that make GCBASIC the easiest tool set available - supporting over 1400 microcontrollers with tools to make this fun and simple. Please see the download section for your options. We have two IDEs, we have just the compiler and we have a minimal install - it is your choice. Please see the homepage here: https://gcbasic.com

X11-Basic is a dialect of the BASIC programming language with graphics capability that integrates features like shell scripting, cgi-Programming and full graphical visualisation into the easy to learn basic language on modern computers.

An Open Source Basic Compiler with ability to use OpenGL. Complete with IDE (Windows only).

The purpose of this project is to create and update a beginners guide to FreeBASIC. Over the years I have noticed that there was only three real ways to learn FreeBASIC. The FreeBASIC Documentation, the FreeBASIC Community Forum, and A old beginners guide written by Richard D. Clark and Ebben Feagan. Each of these sources are great, but they all assume some experience with a programming language. This Project is taking Richard D. Clark's and Ebben Feagan's "A Beginner's Guide to FreeBasic" and is editing, updating, reorganizing, and simplifying this guide. Mr. Clark and Mr. Feagan generously open sourced there guide so I could start this project. Without being able to stand on their shoulders I could not have even started this project. Please check out my homepage for updated information and ways you can help with this ongoing project. If you can please buy me a hamburger as it is hard writing a book.

John's Mutant contains several projects. The current project is an ECMA-55 Minimal BASIC compiler for Linux systems using AMD64 compatible CPUs. You can download the MinimalBASIC compiler source in the Files section.

SpeedBasic Translator. Converts basic oop syntax to c++.

Amiblitz is the further develop of BlitzBasic 2 from Amiga. Acid Soft was so friendly to release the BB2 source as Opensource. BlitzBasic is port to PC and further develop here too. We choose the Name Amiblitz for Amiga Version to make clear its different now. Newer Versions are available from https://github.com/AmiBlitz !

Basic4Games will be a BASIC programming language for Windows and Linux. Will be the successor to Basic4GL.

A compiler and cross-compiler for (Currently) Cobol (with Fortran being added later). It is intended to be the first self-hosted open-source Cobol Compiler, e.g. the compiler itself will be written using Cobol.

An open source compiler for the Crystal programming language.

Modular BCX. BASIC translator based on BCX project hosted at: http://groups.yahoo.com/group/bcx/. Modular Cross platform implementation targeting C, C++, C#, Java and possibly other output languages.

BASIC programming language for Windows and Linux.

A dynamic and object-oriented programming language for developing extensions of modifiable applications. Features: OOP, flexible syntax, vectorial operations, dynamic linked lists, IDE, HTML generator, includeable DLL an so on.

Modern object oriented Basic compiler, generates equivalent C++ code, maganing QT widgets and classes natively.

QuickerBasic is a QuickBasic 4.5 compatible compiler which attempts to implement as much of the QuickBasic language as possible, as well as extending it.

UltraBasic is a QBasic compatible compiler, written originally by Gabriel Fernandez, and continued until 2004 by Angelo Rosina. It was hosted on Geocities, and has been moved here because of Geocities shutdown. Source code is in QB PDS 7.

Vilegust - named for the codesmells that eventually come of such projects - is a basic-like interpreter/compiler project in vb.net that will eventually be self-compilable.

Elice is a free compiler for programs written in the proprietary language PureBasic. It compiles those programs to C++ and then uses g++ to generate an executable. This is an old version. Development has moved to https://gitorious.org/elice/

ForceBasic - This is programming language for development software. Selecting unit library you can write program for some operation system. ForceBasic compiler can build crosspatform code, who executing with help virtual machine.

nbasic - bytecode compiler+vm for middle level programming language, like basic. nbs - small and fast C-coded object orientated basic (compiler+vm) for embeded applications. Purpose: scripting support for C/C++ project.

Hello Here is a small easy example to write Basic Code in C ++. It helped me to learn c ++. You can easily create a gui. When changing the window sizes, the buttons change propotionally! write Basic directly in the C ++ compiler. Simply create the Gui in Linux have fun ;-)

BCX (Basic to C Translator) BCX is a small command line tool that inputs a BCX BASIC source code file and outputs a C source code file which can be compiled with many C or C++ compilers.
