• C/C++跨平台的的预编译宏

    我们在编译一些跨平台的程序的时候难免会遇到_WIN32  __linux__什么之类的SDK或者编译器环境预定义的宏。有很多，之前还分不清_WIN32 和WIN32的区别。不过这里还好有个列表，做个备忘。

    AIX

    TypeMacroDescription
    Identification _AIX  
    Version _AIX'VR' V = Version
    R = Revision
    Identification __TOS_AIX__ Defined by xlC
    Example

    If _AIX is defined, then the following macros can be used to determine the version. Notice that the macros indicates the mentioned version or higher. For example, if _AIX43 is defined, then _AIX41 will also be defined.

    GNU aka GNU/Hurd

    The official name of this operating system is GNU. Hurd is the kernel in the GNU operating system. It is often listed as GNU/Hurd since there is also GNU/Linux and GNU/kFreeBSD, which are most of the GNU operating system with the Linux and FreeBSD kernels respectively.
