Harbour Forks

Harbour by vszakats (version 3.4)

Forked in April of 2013 in an attempt to focus on a narrower set of platforms and contrib libraries while also freeing up resources by distancing from project/community management tasks. This fork focuses on Linux, Windows (64-bit) and macOS, and some selected C compilers (clang, gcc/MinGW). It has the stated goal to adapt all mainline (non-fork) updates with minimal delay. To ease maintenance, this fork has the policy to disable all deprecated components by default (they can be enabled though, with no promises). Other goals are compatibility with mainline core, continuous maintenance, build automation and security (hbcrypto contrib and curl/OpenSSL builds). It also features a large number of fixes and cleanups, many of which are eventually retrofitted to mainline.

This fork accepts donations.

This fork is largely compatible with mainline, with the notable exception for deprecated parts, which are disabled by default.


Forked in 2001 with the goal of providing a more aggressive development path with a different approach to language extensions and compatibility and more focus on the Windows platform along with commercial offerings.
