Build a program with Make.gfxtools.rules

These steps describe how to compile a hello world program with the $G makefiles. For now, we will walk you through doing this in your home directory. Normally, once you have a file or two to work with, you will then take this source and put it in CVS under $G/src, then continue to develop in that directory. You will find out how to import the simple program you make here into the $G/src tree in the next tutorial.
  1. cd
  2. mkdir testprog
  3. cd testprog
  4. edit main.cpp to contain the following example program: 
    #include <stdio.h>

int main(int argc, char **argv)
{
  printf("hello world\n");
  return 0;
}
  5. edit Makefile to contain the following 
    PROJECT_NAME=testprog
OBJDIR=obj

SRC=main.cpp

# by default, compile just the debug version
all:   progg

# rule to compile the debug version
debug: progg

# rule to compile the optimized version
opt:   progo

# rule to compile the profiling version
prof:  progp

include $(G)/lib/Make.gfxtools.rules
-include Makefile.depend
  6. make all
  7. try running it with: "obj/testprog-d"
  8. try making an optimized version: make opt
  9. try running it: "obj/testprog"
  10. you can also run "make clean" to delete all the compiled sources
Notes: The -d is appened automatically to debug version of programs and libraries. A -p is appended for the profiling versions. The name for the optimized version is taken directly from the PROJECT_NAME Makefile variable.
