Hi Chris,<br>
I met this, so I add export INCLUDES=-I%{_includedir}:<br>

I saw but I am concerned there is more to this. I think INCLUDES is specific to automake.<span class=""><br>

This is a CPP action and not a CC action. This is the root of the problem as the CPPFLAGS is not being set.<span class=""><br>

The include path to the BSP headers is present in CFLAGS but there is no CPPFLAGS defined by the RSB and we need to have the path in the CPPFLAGS. I have a patch I am testing which adds this. Once the symbols issue is resolved and I can test the whole process I will push the change.<div class="HOEnZb"><div class="h5"><br>
