1. Create a directory for your project, and copy one of the example project makefiles into the project directory.
2. Open the copied makefile and set the variable DEVICE to the target device.
3. Set the variable GCC_DIR to point to the directory where the GCC MSP430 package is installed.
4. Include all of the project source files (that is, the *.c files) as a dependency for the first target of the makefile.
5. Go to the project directory in a terminal. Type make to build the project or make debug to debug the project.
