Build Error on OSX - can't find rsa.h


When getting a fresh git clone of mesh-develop or feature/ble-peripheral I get the following error after make clean all:

src/handshake.h:31:25: fatal error: mbedtls/rsa.h: No such file or directory

If I look in /usr/local/include/mbedtls I see rsa.h. I’ve installed all the listed tools for osx. Any tips on what’s missing from the make recipe?

BLE Central Mode

Do a git submodule update --init --recursive in the root directory and try again


Well, this certainly made a difference but I get a new error shown below. BTW, I’m following directions from here. No mention there of building for mesh targets so perhaps I need some more make flags?

I think you’re missing a parameter in the build command. You’re building for Core, but you can’t build mesh-develop for core. Try something like:

cd firmware/modules
make clean all PLATFORM=xenon


Thanks! With the PLATFORM=xenon and cd firmware/modules it built without errors. Now I just need to figure out how to use the output for debugging. Is this documented anywhere for the mesh devices?
