At most one of these is true, the rest are false. TARGET_CPU_PPC - Compiler is generating PowerPC instructions for 32-bit mode TARGET_CPU_PPC64 - Compiler is generating PowerPC instructions for 64-bit mode TARGET_CPU_68K - Compiler is generating 680x0 instructions TARGET_CPU_X86 - Compiler is generating x86 instructions TARGET_CPU_MIPS - Compiler is generating MIPS instructions TARGET_CPU_SPARC - Compiler is generating Sparc instructions TARGET_CPU_ALPHA - Compiler is generating Dec Alpha instructions TARGET_OS_* These conditionals specify in which Operating System the generated code will run. At most one of the these is true, the rest are false. TARGET_OS_MAC - Generate code will run under Mac OS TARGET_OS_WIN32 - Generate code will run under 32-bit Windows TARGET_OS_UNIX - Generate code will run under some non Mac OS X unix TARGET_RT_* These conditionals specify in which runtime the generated code will run. This is needed when the OS and CPU support more than one runtime (e.g. Mac OS X supports CFM and mach-o). TARGET_RT_LITTLE_ENDIAN - Generated code uses little endian format for integers TARGET_RT_BIG_ENDIAN - Generated code uses big endian format for integers TARGET_RT_64_BIT - Generated code uses 64-bit pointers TARGET_RT_MAC_CFM - TARGET_OS_MAC is true and CFM68K or PowerPC CFM (TVectors) are used TARGET_RT_MAC_MACHO - TARGET_OS_MAC is true and Mach-O/dlyd runtime is used ****************************************************************************************************/ /* * gcc based compiler used on Mac OS X */ #if defined(__GNUC__) && ( defined(__APPLE_CPP__) || defined(__APPLE_CC__) || defined(__MACOS_CLASSIC__) ) #define TARGET_OS_MAC 1 #define TARGET_OS_WIN32 0 #define TARGET_OS_UNIX 0 #if defined(__ppc__) #define TARGET_CPU_PPC 1 #define TARGET_CPU_PPC64 0 #define TARGET_CPU_68K 0 #define TARGET_CPU_X86 0 #define TARGET_CPU_MIPS 0 #define TARGET_CPU_SPARC 0 #define TARGET_CPU_ALPHA 0 #define TARGET_RT_LITTLE_ENDIAN 0 #define TARGET_RT_BIG_ENDIAN 1 #define TARGET_RT_64_BIT 0 #ifdef __MACOS_CLASSIC__ #define TARGET_RT_MAC_CFM 1 #define TARGET_RT_MAC_MACHO 0 #else #define TARGET_RT_MAC_CFM 0 #define TARGET_RT_MAC_MACHO 1 #endif #elif defined(__ppc64__) #define TARGET_CPU_PPC 0 #define TARGET_CPU_PPC64 1 #define TARGET_CPU_68K 0 #define TARGET_CPU_X86 0 #define TARGET_CPU_MIPS 0 #define TARGET_CPU_SPARC 0 #define TARGET_CPU_ALPHA 0 #define TARGET_RT_LITTLE_ENDIAN 0 #define TARGET_RT_BIG_ENDIAN 1 #define TARGET_RT_64_BIT 1 #define TARGET_RT_MAC_CFM 0 #define TARGET_RT_MAC_MACHO 1 #elif defined(__i386__) #define TARGET_CPU_PPC 0 #define TARGET_CPU_PPC64 0 #define TARGET_CPU_68K 0 #define TARGET_CPU_X86 1 #define TARGET_CPU_MIPS 0 #define TARGET_CPU_SPARC 0 #define TARGET_CPU_ALPHA 0 #define TARGET_RT_MAC_CFM 0 #define TARGET_RT_MAC_MACHO 1 #define TARGET_RT_LITTLE_ENDIAN 1 #define TARGET_RT_BIG_ENDIAN 0 #define TARGET_RT_64_BIT 0 #else #error unrecognized GNU C compiler #endif /* * CodeWarrior compiler from Metrowerks/Motorola */ #elif defined(__MWERKS__) #define TARGET_OS_MAC 1 #define TARGET_OS_WIN32 0 #define TARGET_OS_UNIX 0 #if defined(__POWERPC__) #define TARGET_CPU_PPC 1 #define TARGET_CPU_PPC64 0 #define TARGET_CPU_68K 0 #define TARGET_CPU_X86 0 #define TARGET_CPU_MIPS 0 #define TARGET_CPU_SPARC 0 #define TARGET_CPU_ALPHA 0 #define TARGET_RT_LITTLE_ENDIAN 0 #define TARGET_RT_BIG_ENDIAN 1 #elif defined(__INTEL__) #define TARGET_CPU_PPC 0 #define TARGET_CPU_PPC64 0 #define TARGET_CPU_68K 0 #define TARGET_CPU_X86 1 #define TARGET_CPU_MIPS 0 #define TARGET_CPU_SPARC 0 #define TARGET_CPU_ALPHA 0 #define TARGET_RT_LITTLE_ENDIAN 1 #define TARGET_RT_BIG_ENDIAN 0 #else #error unknown Metrowerks CPU type #endif #define TARGET_RT_64_BIT 0 #ifdef __MACH__ #define TARGET_RT_MAC_CFM 0 #define TARGET_RT_MAC_MACHO 1 #else #define TARGET_RT_MAC_CFM 1 #define TARGET_RT_MAC_MACHO 0 #endif /* * unknown compiler */ #else #if defined(TARGET_CPU_PPC) && TARGET_CPU_PPC #define TARGET_CPU_PPC64 0 #define TARGET_CPU_68K 0 #define TARGET_CPU_X86 0 #define TARGET_CPU_MIPS 0 #define TARGET_CPU_SPARC 0 #define TARGET_CPU_ALPHA 0 #elif defined(TARGET_CPU_PPC64) && TARGET_CPU_PPC64 #define TARGET_CPU_PPC 0 #define TARGET_CPU_68K 0 #define TARGET_CPU_X86 0 #define TARGET_CPU_MIPS 0 #define TARGET_CPU_SPARC 0 #define TARGET_CPU_ALPHA 0 #elif defined(TARGET_CPU_X86) && TARGET_CPU_X86 #define TARGET_CPU_PPC 0 #define TARGET_CPU_PPC64 0 #define TARGET_CPU_68K 0 #define TARGET_CPU_MIPS 0 #define TARGET_CPU_SPARC 0 #define TARGET_CPU_ALPHA 0 #else /* NOTE: If your compiler errors out here then support for your compiler has not yet been added to TargetConditionals.h.

The short term work around is to set the TARGET_CPU_ and TARGET_OS_ on the command line to the compiler (e.g. -DTARGET_CPU_MIPS=1 -DTARGET_OS_UNIX=1) The long term solution is to add a new case to this file which auto detects your compiler and sets up the TARGET_ conditionals.
