在编写跨平台的程序时，我们经常使用预定义宏来检测编译环境。虽然编译器的手册中有预处理宏的介绍，但是不够详细，而且还有很多宏没有介绍。于是，我编写了一个小程序，显示常见C/C++编译器的编译器的预定义宏。
一、心得
最直接的办法是逐个逐个的用#ifdef判断宏是否存在，然后再printf显示其内容。可是预定义宏有些是整数、有些是字符串，还有些是关键字不能直接用printf输出，用起来挺麻烦的。
在网上发现一种不错办法，出自《关于CPP的预定义宏：unix、linux、i386、i586，大家中过招吗？》4楼“太平绅士”——

#include <stdio.h> #define PT_MAKE_STR(x) { #x, PT_MAKE_STR_ESC(x) } #define PT_MAKE_STR_ESC(x) #x typedef struct { const char *name; const char *value; } MACRO_T; /* Compilers */ const MACRO_T g_compilers[ ] = { #ifdef __INTEL_COMPILER /* Interl C++ */ PT_MAKE_STR( __INTEL_COMPILER ), #endif #ifdef _MSC_VER /* Visual C++ */ PT_MAKE_STR( _MSC_VER ), #endif #ifdef __GNUC__ /* GCC */ PT_MAKE_STR( __GNUC__ ), #endif #ifdef __DMC__ /* DMC++ */ PT_MAKE_STR( __DMC__ ), #endif #ifdef __ARMCC_VERSION /* ARM C/C++ */ PT_MAKE_STR( __ARMCC_VERSION ), #endif }; /* Operation system */ const MACRO_T g_platforms[ ] = { #ifdef _WIN32 /* Windows 32 or Windows 64 */ PT_MAKE_STR( _WIN32 ), #endif #ifdef _WIN64 /* Windows 64 */ PT_MAKE_STR( _WIN64 ), #endif #ifdef __MINGW32__ /* Windows32 by mingw compiler */ PT_MAKE_STR( __MINGW32__ ), #endif #ifdef __CYGWIN__ /* Cygwin */ PT_MAKE_STR( __CYGWIN__ ), #endif #ifdef __linux__ /* linux */ PT_MAKE_STR( __linux__ ), #endif #ifdef __FreeBSD__ /* FreeBSD */ PT_MAKE_STR( __FreeBSD__ ), #endif #ifdef __NetBSD__ /* NetBSD */ PT_MAKE_STR( __NetBSD__ ), #endif #ifdef __OpenBSD__ /* OpenBSD */ PT_MAKE_STR( __OpenBSD__ ), #endif #ifdef __sun__ /* Sun OS */ PT_MAKE_STR( __sun__ ), #endif #ifdef __MaxOSX__ /* MAC OS X */ PT_MAKE_STR( __MaxOSX__ ), #endif #ifdef __unix__ /* unix */ PT_MAKE_STR( __unix__ ), #endif }; /* Other useful */ const MACRO_T g_others[ ] = { #ifdef __DATE__ PT_MAKE_STR( __DATE__ ), #endif #ifdef __TIME__ PT_MAKE_STR( __TIME__ ), #endif #ifdef _BSD_SOURCE PT_MAKE_STR( _BSD_SOURCE ), #endif #ifdef _POSIX_SOURCE PT_MAKE_STR( _POSIX_SOURCE ), #endif #ifdef _XOPEN_SOURCE PT_MAKE_STR( _XOPEN_SOURCE ), #endif #ifdef _GNU_SOURCE PT_MAKE_STR( _GNU_SOURCE ), #endif #ifdef __GNUC_MINOR__ PT_MAKE_STR( __GNUC_MINOR__ ), #endif #ifdef __VERSION__ PT_MAKE_STR( __VERSION__ ), #endif #ifdef __unix PT_MAKE_STR( __unix ), #endif }; int main( int argc, char **argv ) { int i; printf( "/* Compiler definitions. */\n" ); for( i = 0; i < sizeof( g_compilers ) / sizeof( g_compilers[ 0 ] ); ++i ) { printf( "#define %s %s\n", g_compilers[ i ].name, g_compilers[ i ].value ); } printf( "\n" ); printf( "/* Platform definitions. */\n" ); for( i = 0; i < sizeof( g_platforms ) / sizeof( g_platforms[ 0 ] ); ++i ) { printf( "#define %s %s\n", g_platforms[ i ].name, g_platforms[ i ].value ); } printf( "\n" ); printf( "/* Other definitions. */\n" ); for( i = 0; i < sizeof( g_others ) / sizeof( g_others[ 0 ] ); ++i ) { printf( "#define %s %s\n", g_others[ i ].name, g_others[ i ].value ); } printf( "\n" ); return 0; }
该方法巧妙的利用“#”运算将宏转成了字符串并填写数组，然后程序只需显示数组内容就行了。
我在该方法的基础上做了三点改进——
1. main函数中有很多相似的代码，区别仅仅是数组的不同。可以编写一个print_MACRO_T函数来显示MACRO_T数组，然后在main函数中对每一个数组调用该函数。
2. 当某个数组的宏均不存在时，编译器会报错。可以在数组的第一行填上该类别的描述信息，保证编译通过。另一个好处是精简了main函数中显示不同类别描述信息的代码。
3. 某些编译器不支持内容为空的宏（如BCB6）。这时只有手动#if做兼容性处理了。
二、全部代码
预定义宏的数据来自——C11标准、C++11标准，及VC、BCB、Intel、GCC这些编译器。
最初想删除重名的宏，后来考虑到需要对照各个编译器的手册，所以还是允许重名比较好。
