TD5/C/Makefile

   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=infovols
  15 BUILD_TYPE=debug
  16 #BUILD_TYPE=release
  17 LDLIBS=-lmysqlclient
