Generic Makefile For C Projects. Supports different building modes (Debug and Release preconfigured).
Supports building mode specific configurations.
C source code dependencies are computed automatically by the compiler and included into the makefile.
All object files are put under directory $(TargetDir)/$(buildmode)/$(Project)/.

| # Generic Makefile (c) 2013 Jörg Seebohn | |
| # Version 1.0 | |
| # Use it at your own risk ! | |
| # This Makefile depends on GNU make. | |
| # The clean command uses "@echo rm -rf $(TargetDir)" | |
| # remove the echo if you know that $(TargetDir) is set to a valid value. | |
| # The target test builds the project in Release mode and starts it. | |
| # Adapt project specific part to your own project. | |
| # Adapt compiler specific part to your own compiler. | |
| # Compiler gcc is preconfigured. | |
| # Mode specific values are added after the mode agnostic values. | |
| # The generated binary is stored as $(TargetDir)/$(Project)_$(buildmode) | |
| # except for the Release binary. It is named $(TargetDir)/$(Project). | |
| # You can change the location by changing macro TargetFilename. | |
| # The object files are stored in directory $(TargetDir)/$(buildmode)/$(Project) | |
| # You can change the location by changing ObjectFilename | |
| # Variable "Modes" contains the list of build modes. Add your own mode with "Modes += mymode" if you like and add | |
| # additional compiler and linker flags with "CFlags_mymode := " and "LFlags_mymode := ". | |
