One Object Pascal codebase that builds and passes its tests on both Delphi and Lazarus/FPC 3.2.2. Use when a Delphi project must also run on Lazarus (or vice versa); when something compiles or works on one compiler but not the other; when writing {$IFDEF FPC} code, .inc files, {$MODE DELPHI} vs objfpc, .dpr/.dproj/.lpr/.lpi/.lpk/.groupproj/.lpg files, mirrored DUnitX+FPCUnit tests or FPC/Linux CI; when writing or porting anything RTTI-driven (TypInfo, TRttiContext, TValue, attributes…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Dual-compiler Delphi/Lazarus

Consolidated knowledge from 5 real-world open-source projects that keep a single codebase compiling on both Delphi and Lazarus/FPC. The goal of this skill is to avoid re-discovering, project after project, the same divergences between Delphi's RTL and FPC's RTL — and to give a project structure that is dual-compiler-ready from day one.

Reference projects used as live examples throughout this skill (all public on GitHub, MIT/Apache-licensed by their author):

| Project | Repository | Role |
|---|---|---|
| pascal-amqp-faa | https://github.com/fabianoallex/pascal-amqp-faa | Canonical source of the RTL/threading/socket gotcha table — the sibling projects below explicitly cite this one as their reference |
| pascal-dfe-broker | https://github.com/fabianoallex/pascal-dfe-broker | Best example of structured documentation (`CLAUDE.md` + `CONTRIBUTING.md` + `docs/`) and the only one with real CI (GitHub Actions running the FPC suite) |
| pascal-pipes-faa | https://github.com/fabianoallex/pascal-pipes-faa | Example of a 3rd platform axis (Windows/Linux/Android) and of why `{$IFDEF}` ordering matters |

How to install

The exact contents, by fingerprint
mdr add fabianoallex/pascal-skills-faa/dual-compiler-delphi-lazarus@sha256:b0230457defae6c5

The line at the top of this page pins the label git:20261022.f5758f2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
