Hi Justin, In your makefile, add the CC and CXX defined variables: --------8<-------- CC := gcc -idirafter /home/justin/kcool CXX := g++ -idirafter /home/justin/kcool # yada yada yada... --------8<-------- Or you can do it from the command line: make CC='gcc -idirafter /home/justin/kcool' CXX='g++ -idirafter /home/justin/kcool' -f MyKCoolProject If your makefile isn't using $(CC) and $(CXX) for compilation (**gasp**!), you'll need to find an alternative.
