makefile

This is a makefile I have been using for a while in a variety of projects, intended to be drop-and-use so that minimal maintenance is needed in the makefile itself, as long as I keep consistent directory and file naming schemes. It works mainly for C and C++ with partial support for Fortran sources as well.

What does it do?

Coupled with makedepend.py, this makefile attempts to automatically setup linking dependencies (which .o files are necessary for linking a certain program?) without ever having to manually modify the makefile itself. Note that header dependencies (which .h files are necessary to compile a given .c file?) are not dealt with directly and instead are taken care of by GCC's -MMD -MP -MF flags.

How to make it work?

In order for the setup to work, a couple of conventions must be followed.

• Name source files containing main() function or PROGRAM subroutine as main_name.*, which will generate binary files bin/name
• Put all header files (.h, .hpp, .inc, ...) in include/ directory
• Put all source files (.c, .cpp, ...) in src/ directory
• For Fortran only, name_*.f are set as dependencies of bin/name

How do I use it?

Make targets include:

• cleanbuild delete all temporary files (*.o, *.mod)
• clean cleanbuild + delete binary programs (bin/*)
• cleanall clean + delete dependency information (.d/)
• [default] when called without target, builds every main_name.*
