How can I setup my environment to build my own ril library?

Question

I want to modify Radio Layer Interface(RIL), but I just have the ril source and when I try to build my own binary of rild with NDK's toolchain (arm-linux-androideabi-4.6) I get a bug like this:

rild.c:27:27: fatal error: telephony/ril.h: No such file or directory
compilation terminated.

How can I setup my environment, step by step, to build my own ril library?

Answer 1

Apparently your project is not able to find the request library. Have a look in this detailed tutorial:

• Working with the Radio Layer Interface (RIL) in Android

After following all the step, take care to double check if you have all the files visible to your project or properly set in your environment path.
