When building a target for the simulator I get a fatal error

[greatjack]

I am trying to create a rockbox build for a ui simulator and when i run the make command the command ends with the following error /Users/jack/documents/rockbox/rockbox/firmware/include/rbendian.h:27:10: fatal error:
      'endian.h' file not found

Anyone know how to fix this?

Can you provide some more details about your build environment? What operating system, word size (32 or 64), and what compiler?

I am compiling on mac os x el capitan, using  a 64 bit system.

In the end I just ended up using my ubuntu machine and everything works fine.

Unless something has changed, you need gcc on OSX, not llvm.  Since you didn't mention which compiler you used, I'm guessing you tried the default (llvm), not gcc.
