Fpcmake is a makefile generator. It generates a makefile named "Makefile" from a definition file called "Makefile.fpc" and its own built-in template. It is used in the FPC source tree (e.g. in FPC 2.6.0), but is planned to be succeeded by FPMake.

This template is located in utils/fpcm/fpcmake.ini, but since fpcmake.ini is included in the binary (to avoid path-searching issues), fpcmake has to be regenerated for each fpcmake.ini change.

The manual has a quite good chapter about Makefile.fpc syntax, and examples teach the rest (fpcmake.ini, the various Makefile.fpcs in the FPC source tree).

It defines some default targets that are always present:

  • Clean -- clean all programs and the units explicitly stated to be cleaned, but not other units.
  • Cleanall -- also clean all units (*.ppu).


  • I get an error message that the command __missing_command__ is missing. -- This happens when a tool required by the make process is not found. Remedy: Add the path to the tool as an option to make, like DATA2INC=/path/to/data2inc, for the tool data2inc
  • Clean does not delete the files I expect. -- This happens when the files were generated by a call to make where certain options were given. Remedy: Call make clean with the same options. Options which may affect this are:
    • FPC or PP (Tells make which version of the compiler created the files, this affects *.*w files generated for Windows for fpc < 1.1. To erase these files, please give an fpc 1.0 compiler as a parameter)
  • Make cannot find tools asw, ldw. Happens only when making for fpc 1.0.*. Remedy: Make a copy of the tools as and ld, rename them asw, ldw.
  • Target not supported: bad parameters were used when generating the makefile, you need to regenerate it with -Tall (see next paragraph)

Regenerating makefiles

Regenerating a Makefile from Makefile.fpc is quite easy. The basic syntax is

fpcmake -w -Tall

  • -w : actually _write_ the Makefile.
  • -Tall : generate the makefile so as to work on all platforms (default is only the host platform). DON'T FORGET THIS WHEN COMMITTING TO FPC / LAZARUS SVN SERVER!. For lazarus developers: YOU MUST USE THE FPC DEVELOPER VERSION (trunk, e.g. 2.7.1) TO GET ALL PLATFORMS.
  • It is possible to add -v to increase verbosity.

If you regenerate makefiles outside the fpc/ SVN tree, (e.g. for lazarus in projects), and fpcmake complains it can't find package.fpc for the RTL package, try setting the environment variable FPCDIR to the FPC source directory.

(Unix/Linux/OSX bash/sh) E.g. if your FPC directory is located in /location/to/fpc:

export FPCDIR=/location/to/fpc

(DOS/Windows/OS/2) E.g. if your FPC directory is located in c:\location\to\fpc:

set FPCDIR=c:\location\to\fpc
