I'm probably doing something wrong but I don't know how to proceed. Would like a pointer if anyone knows.
I can compile the library. But now I want to cross-compile to ARMv8.
When i change the build command from
cmake ..
to
cmake .. -DCMAKE_C_COMPILER="aarch64-linux-gnu-gcc"
The compiler command changes from
/usr/bin/cc -Dmraa_EXPORTS -I/home/erik/projects/dragonboard-sensors/vendor/mraa/api -I/home/erik/projects/dragonboard-sensors/vendor/mraa/api/mraa -I/home/erik/projects/dragonboard-sensors/vendor/mraa/include -I/usr/include/json-c -Wall -Werror=main -Wformat -Wmain -Wuninitialized -Winit-self -Werror=implicit -Werror=missing-parameter-type -DONEWIRE=1 -DX86PLAT=1 -DJSONPLAT=1 -fPIC -std=gnu99 -o CMakeFiles/mraa.dir/mraa.c.o -c /home/erik/projects/dragonboard-sensors/vendor/mraa/src/mraa.c
/usr/bin/aarch64-linux-gnu-gcc -Dmraa_EXPORTS -I/usr/include -I/home/erik/projects/dragonboard-sensors/vendor/mraa/api -I/home/erik/projects/dragonboard-sensors/vendor/mraa/api/mraa -I/home/erik/projects/dragonboard-sensors/vendor/mraa/include -I/usr/include/json-c -Wall -Werror=main -Wformat -Wmain -Wuninitialized -Winit-self -Werror=implicit -Werror=missing-parameter-type -DONEWIRE=1 -DX86PLAT=1 -DJSONPLAT=1 -fPIC -std=gnu99 -o CMakeFiles/mraa.dir/mraa.c.o -c /home/erik/projects/dragonboard-sensors/vendor/mraa/src/mraa.c
The added -I/usr/include will cause the wrong headers to be included and compilation will fail.
-I/usr/include
This is fixed when I remove line https://github.com/intel-iot-devkit/mraa/blob/0a12c5a0177f9fa8e7c4c564e70a65c4a0bb81af/CMakeLists.txt#L143
When cross compiling, you might need to specify a cmake toolchain file.
