1 | # Sample Makefile to build simple project. |
| 2 | # | |
| 3 | # This Makefile expect all source files (.c) to be at the same level, in the | |
| 4 | # current working directory. | |
| 5 | # | |
| 6 | # It will automatically generate dependencies, compile all files, and produce a | |
| 7 | # binary using the provided name. | |
| 8 | # | |
| 9 | # Set BINARY_NAME to the name of the binary file to build. | |
| 10 | # Set BUILD_TYPE to either debug or release | |
| 11 | # | |
| 12 | # Automatic dependencies code from: | |
| 13 | # http://make.mad-scientist.net/papers/advanced-auto-dependency-generation/#tldr | |
| 14 | BINARY_NAME=exo1 | |
| 15 | LIBOBJS=clist.o # object to put in the library | |
| 16 | LIBRARY_NAME=libtpC | |
| 17 | BUILD_TYPE=debug | |
