Unofficial macOS Lazarus and FPC Snapshots

I am currently making daily, automated, untested builds of the Lazarus development version (trunk in svn, main in git) for macOS -- Cocoa, 64 bit, Intel + aarch64 (M1) processors -- available on SourceForge.

There is also a daily, automated, untested build of the development version (trunk in svn, main in git) of the Free Pascal Compiler for macOS -- aarch64 (M1) processor only.

The only guarantee is that the software compiled successfully using a recent development version of FPC. THIS IS COMPLETELY UNTESTED SOFTWARE. Caveat Utilitor!

Official Snapshots

This page is kept in the hope that at some time it may be restored.

Snapshots are nightly builds of lazarus using the latest available sources and with the latest fixes and new bugs. There are several lazarus snapshots available:

  • Source: Lazarus fixes in zip and bz2

I have written a program with fpcunit and lNet to check, if the daily snapshots are refreshed. You can view the report, which is refreshed every 15 minutes. stopped working.


Warning: These snapshots are generated automatically and are untested. The only thing we can say is, that the compiler found the source good enough to compile. These snapshots are provided as a courtesy only. If they don't work, too bad! If they destroy your project files, crash your machine, and eat your disk: tough luck! (just to say that YOU ARE USING COMPLETELY UNTESTED SOFTWARE)
