Harbour

An open source, multi-platform object-oriented xBase database compiler that uses a C compiler as a back end to generate binaries. Although it has been forked a couple of times, Harbour is the oldest open source Clipper clone out there (if we ignore old xBase in Clipper DOS tools like nanoBase) and has by far the largest mindshare out there, not the least because they have had a rather conservative attitude towards development and platform support.

Versions

• Latest version: v.3.0.0

Prerequisites

• Open Watcom C compiler, used to compile the output of the xHarbour compiler into machine code.
• GCC compiler, alternative tool to compile the output of the xHarbour compiler into machine code, available in versions for both the 3.x and 4x GCC Branches.

Note that using the GCC back end means that the complied binary will rely on GCC DLL's
