I tried to include my external library as an external module, but it doesn’t work ! I have still the same issue. When we’re trying to compile it, it seems that the makefile isn’t able to find the functions include in this libmbed.a.
As you can see in my Makefile, I use this var:
AJOUT MODULE MBED
EXTERNAL_MODULE_DIRS += “YOUR_PATH”/RIOT-master/examples/test USEMODULE += libmbed INCLUDES += -I/”YOUR_PATH”/RIOT-master/MBED
I export all .o depending on my board and create the libmed.a with the command “ar -q libmed.a” . I use the mbed export to gcc, compile it with the “GCC ARM Embedded 4.7 update 4” Toolchain and it works ! But when I tried to compile with RIOT-OS, its like it isn’t able to find the functions include in this lib.
