Hi Cenk, Thanks for your reply, I finished read the Makefile.modules and fully understood!
Hi all, I also curious about the RIOT platform, do we have the STL tools or map, multimap or linked list utility directly for use? Or I can work my own data structure for use, if has, I can focus only on functionality.
