osg与VC++6.0

Guogenhua

我写了一个简单的基于windows控制台的osg程序，平台是vs 2005，运行没有问题。由于需要，我把它移植到了VC++ 6.0,工程属性设置都没变，但是无法编译，出现了以下错误和警告，不知道为什么？

osg在VC++ 6.0下需要进行什么特殊的配置吗？我用的osg是2.2的

array

osg很早就不再提供对vc6的支持了，主要是由于vc6对于C++ STL模板的糟糕支持实在让人无法容忍。网络上的说法是可以使用STLPort替换vc6自己的破旧模板库，然后再编译osg。不过由于编译器比较古老，很难说这样会产生什么问题，osg官方也明确表示不再提供vc6环境相关的技术支持
