Questo e' il file CMakeLists.inc che dovrei modificare per addattarlo alla toolchain mipsel:Hi, porting the libgbee to MIPSEL/OpenWRT shouldn't be too difficult. Each libgbee port implements a defined set of operations allowing the libgbee to communicate with the XBee module. The libgbee calls these routines using C-Macros. Check out the gbee-port.h file of an existing port to get an idea what each port needs to implement. For your MIPSEL/OpenWRT port you could start with the existing x86/Linux port: it should build out of the box for your target system. To create a new port, you can copy the files from src/port/x86/linux to a new directory, e.g. src/port/mips/linux. Edit the file src/port/mips/linux/CMakeLists.inc to invoke your cross-compiler (check out the CMakeLists.inc for the AT91SAM7 port for an example). Now build your libgbee, see doc/build-instructions.pdf for more information. Hope this helps... please tell me if it works. Best regards, Daniel
