Free Pascal package guidelines

This page explains on how to write PKGBUILDs for software built with the Free Pascal Compiler (FPC). There currently exists two options for building software of Linux, as well as a handful of options for building software on other targets using FPC cross compilers:

• fpc provides a compiler targeting only your host CPU (i686 or x86_64).
• fpc-multilib^{AUR[broken link: archived in aur-mirror]} provides a x86_64 host compiler targeting both i686 and x86_64 CPU Linuxes. This will also provide the ppcross386^{AUR[broken link: archived in aur-mirror]} FPC compiler driver package.

Package naming

The project name alone is usually sufficient. However, in the case of cross-compiling, the package should be prefixed with fpc32- when targetting i686 Linux from multilib and named in the format of fpc-cpu-system-pkgname when targetting non-Arch Linux systems.

Helpful snippets

• Determine FPC's version and the CPU and OS of the units to output:

_unitdir=`fpc -iSP`-`fpc -iSO`
_fpcver=`fpc -iV`

Packaging

Please adhere to the following when making an FPC-based package:

• always add fpc to either makedepends or depends
• always put all compiled units (*.a, *.compiled, *.o, *.ppu, *.res, *.rst) under /usr/lib/fpc/$_fpcver/units/$arch-linux
• add staticlibs to options if installing an import library

Cross compiling

• always add the corresponding cross compiler package mentioned above (fpc-cpu-system-rtl or fpc-multilib^{AUR[broken link: archived in aur-mirror]} for multilib) to depends
• always add !strip to options for non-Unix-based systems
• always put all compiled units (*.a, *.compiled, *.o, *.ppu, *.res, *.rst) under /usr/lib/fpc/$_fpcver/units/$_unitdir (or if multilib, /usr/lib/fpc/$_fpcver/units/i386-linux)
• always use any (x86_64 if multilib) as the architecture
• add staticlibs to options if installing an import library
