VC编译器的编译链接参数非常之多，对程序生成在细节上的控制也是非常强大的。要深入了解编译器参数是比较困难的，但作个初步认识还是不太难。
编译参数可以在Project Setting中查看(Project菜单再选择Setting)，如下图：
这些参数究竟代表什么意思了？可以通过在CMD窗口下输入cl /help(注1)查看各个参数的含义。

/Tp<source file> compile file as .cpp /Yu[file] use .PCH file
/TC compile all files as .c /YX[file] automatic .PCH
/TP compile all files as .cpp /Zm<n> max memory alloc (% of default)
-LINKING-链接
/MD link with MSVCRT.LIB /MDd link with MSVCRTD.LIB debug lib
/ML link with LIBC.LIB /MLd link with LIBCD.LIB debug lib
/MT link with LIBCMT.LIB /MTd link with LIBCMTD.LIB debug lib
/LD Create .DLL /F<num> set stack size
/LDd Create .DLL debug libary /link [linker options and libraries]
全英文看着慢，其实在MSDN上可以找到中文说明。运行MSDN后，点击“目录”再在右边选择——开发工具和语言-->Visual Studio文档-->Visual C++-->生成C/C++程序-->C/C++生成参考-->编译C/C++程序-->编译器选项。下图展示了MSDN对编译器选项的说明，当然登录MSDN的网站也可以得到相同的信息。
下一篇将详细解释VC编译器在Debug和Release设置下编译参数的区别。
注1．cl.exe 是一种控制 Microsoft C 和 C++ 编译器和链接器的工具。编译器产生通用对象文件格式 (COFF) 对象 (.obj) 文件。 链接器产生可执行文件 (.exe) 或动态链接库文件 (DLL)。更多内容可以访问MSDN的网站。
