Make sure you have installed a
GNU C compiler supporting your selected device. The C compiler must be present in
the PATH. Also, the ‘make’ utility should be
installed and present in your PATH.
If you checked the "Include Makefile" check box when exporting
the project from Atmel START, the extracted
‘atmelstart.atzip’ file should contain a Makefile
inside the ‘gcc’ folder.
- In the folder where you extracted the
‘atmelstart.atzip’ file, go to the
‘gcc’ sub-folder and open a command prompt.
- Run make.
This will build your project.
