Win32 & Win64 Lazarus+FPC snapshots

About

Since the maintainer for Windows Snapshot builds of Free Pascal and Lazarus snapshots seems to have stopped building them, I set up a system for building compatible (“drop-in”) archives using FPCup. These archives are built manually about once a week. BE WARNED: These are development snapshots. The only check I do is whether it builds, no guarantee is made if the package runs, crashes or destroys your data. You have been warned.

Downloads

• Main Location: Google Drive
• The build skript used: Gitlab

File names follow the scheme Lazarus-{$versionName}-{$svnRev}_fpc-{$versionName}-{$svnRev}_{$buildDate}-{$buildTime}.zip, so newer versions will most likely be showing up at the bottom of the list.

Contents

• Lazarus built from trunk for Platform i368-Win32
• Freepascal built from trunk native for Platform x86_64-Win64 (ppc64)
• Freepascal built from trunk native for Platform i368-Win32 (ppc386)
• GDB 8.3.1 with custom fixes (i386-Win32, x86_64-Win64)
• SVN Changelogs

The directory structure is identical to the one created by the Installers available from the regular repositories, so it is possible to “upgrade” an existing installation by extracting the archive into the same folder and keep file associations.

GDB is a custom-built version containing the following fixes:

• Handle EXCEPTION_INVALID_HANDLE as SIGSYS or ignore, depending on setting ‘stoponinvalidhandle’ (defaults to “ignore”)
• Fix for readline/getch/backspace bug in interactive sessions

FPC is built with the following patches:

• 0032079: always generate rangechecks on case labels, if jumptables are used
• 0025873: {$OPTIMIZATION LEVELn} is equivalent to -On
• 0033603: Add operators as and is for enumerated types (patch 02: including assigned enums)
• 0033093: Casenode: generate more optimizer-friendly code for jumptables
• 0033963: Fix currency multiplication with constant

To see what patches were used for a particular build, starting from 2018-01-21 the patchlist is included in the SVN changelogs.

Installation

1. Extract the archive to suitable location

2. Run makeconfig.cmd to adjust local fpc.cfg

3. Adjust paths in Lazarus config. Use platform macros $(TargetCPU)-$(TargetOS) where needed. A good setup is:

   Compiler Path:	$(LazarusDir)\fpc\3.3.1\bin\$(TargetCPU)-$(TargetOS)\fpc.exe
   FPC Source Directory:	$(LazarusDir)\fpc\$(FPCVer)\source
   Make Path:	$Path($(CompPath))make.exe
   Debugger path:	$(LazarusDir)\mingw\bin\$(TargetCPU)-$(TargetOS)\gdb.exe

   Note: you may have to adjust 3.3.1 to the actual version.

4. Rebuild your IDE to reintegrate your package choices. These are stored in your user profile and should be migrated without issues.

   I tend to build as “Optimized IDE” at this point since it doesn’t actually take that much more time, but gives a noticable speed improvement.
