platform.h: created to allow for much better platform detection
platform.h is a tool I made to allow for effortless detection of the
compiler, OS, and architecture that the app is being compiled for.
- To check the operating system, you can check whether these macros are
defined:
TARGET_OS_WINDOWS
TARGET_OS_MACOSX
TARGET_OS_LINUX
TARGET_OS_SOLARIS // OpenSolaris, Solaris, etc
TARGET_OS_FREEBSD
TARGET_OS_OPENBSD
TARGET_OS_NETBSD
TARGET_OS_DOS
TARGET_OS_NDSFIRMWARE // NDS == Nintendo DS
- To check whether the platform is 32 or 64-bit:
TARGET_CPU_BITS == 32
TARGET_CPU_BITS == 64
- To check your platform's endianness (byte ordering), check whether
these are defined:
TARGET_LITTLE_ENDIAN // x86, x86_64, Alpha, IA64, ARM
TARGET_BIG_ENDIAN // PowerPC, SPARC
- To check for a compiler, you can check whether these macros are
defined:
TARGET_COMPILER_MSVC // Visual C++
TARGET_COMPILER_ICC // Intel C/C++ compiler
TARGET_COMPILER_GCC // GCC
Note that there are some subsets of GCC that you may want
to check for (these macros will be defined *in addition*
to the TARGET_COMPILER_GCC macro:
TARGET_COMPILER_CYGWIN
TARGET_COMPILER_MINGW
TARGET_COMPILER_DJGPP // DOS port
TARGET_COMPILER_BORLAND
