Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-4.2 failed with exit code 255

Does anyone know why this is happening? I get this error when compiling for the simulator, and it's project specific (I tried another project and it worked), so there's probably something wrong with my project settings. Anyone know what exactly?

Answer 1

Fixed the problem. I changed the architectures to Standard(armv6 armv7) rather than just armv6 armv7 .
