Fpcmake is a makefile generator. It generates a makefile named "Makefile" from a definition file called "Makefile.fpc" and its own built-in template.
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, examples teach the rest (fpcmake.ini, the various Makefile.fpc's 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).
Trouble Shooting
- 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 was generated by a call to make where certain options was given. Remedy: Call make clean with the same options. Options which may affect this are:
- OS_TARGET
- CPU_TARGET
- 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 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 devels: YOU MUST USE THE FPC DEVELOPER VERSION (e.g. 2.3.1) TO GET ALL PLATFORMS.
- It is possible to add -v to increase verbosity.
If you regenerate makefiles outside the fpc/ CVS tree, (e.g. for lazarus in projects), and fpcmake complains it can't find package.fpc for the RTL package, try setting the enviroment variable FPCDIR to the fpc source directory fpc/:
(bash/sh) export FPCDIR=/location/to/fpc
(dos/windows/OS/2) set FPCDIR=c:\location\to\fpc
