编译GLUI库，VS2010给了我一个奇怪的名称空间错误 [英] Compiling GLUI library, VS2010 gives me a weird namespace error

问题描述

我为所在的类提供了一个OpenGL项目，它基于GLUI.提供的GLUI库无法正常工作，这就是我尝试自己编译它的原因.因此，我从SourceForge下载了源代码，并尝试编译_glui库.它给了我这个，我找不到关于它的任何信息:

I've got an OpenGL project for a class I'm in, and it's based on GLUI. The provided GLUI library won't work which is why I'm trying to compile it myself. So, I downloaded the source code from SourceForge and try to compile the _glui library. It gives me this, and I can't find any information on it:

等，等等等等

我看了glui.h源文件，第1718和1719行是这样的:

I look at the glui.h source file, and lines 1718 and 1719 have this:

#ifdef _MSC_VER
// Explicit template instantiation needed for dll
template class GLUIAPI std::allocator<GLUI_String>;
template class GLUIAPI std::vector<GLUI_String, std::allocator<GLUI_String> >;
#endif

有人看过吗?

推荐答案

如果有人有更多信息，我很高兴听到它，但是我发现注释掉glui.h中的这一节可以编译它.现在，我们将了解编译后的库是否真正起作用....

If anyone has more info, I'd be glad to hear it, but I found that commenting out the section in glui.h allows it to compile. Now we'll find out if the compiled library actually works....
