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=liste_chainee | |
15 | BUILD_TYPE=debug | |
