今天本想把在游戏中用到的FreeType字体的使用给总结一下,写一个Demo出来的.郁闷的事发生了,用vs2008建了一个空项目,装FreeType相关的一些代码给copy整理出来后,编译后Link是给我来了一大堆的error LNK2005错误:

     反复的检查过代码和工程的属性,发现好像没什么问题,基本上都是libcmtd.lib和MSVCRT.lib的冲突.后来在网上查到这个问题的所在了.问题出在原来snmp_d.lib原来是用MTd方式编译的,而没有办法知道它是这么编译的,但在VC6环境下加入这个库,把工程设为MDd,它居然能够成功编译,这就是问题所在,在VC2008下就没法编译了.所以在VC2008下,必须以MTd方式才可以编译成功.
    解决办法:
       在"Property Pages(项目属性) -> Configuration Properties(配制属性) -> Linker(链接器) -> Command Line(输入) -> Additional options(附加依赖项)"中加入 /NODEFAULTLIB:libc.lib /NODEFAULTLIB:libcmt.lib /NODEFAULTLIB:msvcrt.lib /NODEFAULTLIB:libcd.lib /NODEFAULTLIB:libcmtd.lib
重新编译就可以了.
