visual-studio-2010 - 编译 GLUI 库，VS2010 给我一个奇怪的命名空间错误

Question

我有一个我所在类(class)的 OpenGL 项目，它基于 GLUI。提供的 GLUI 库不起作用，这就是我尝试自己编译它的原因。所以，我从 SourceForge 下载了源代码并尝试编译 _glui 库。它给了我这个，但我找不到任何关于它的信息:

等等等等

我查看了 glui.h 源文件，第 1718 和 1719 行是这样的:

#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

有人以前见过这个吗？

Answer 1

我刚遇到这个问题。那我就跟着做，你可以试试。

(1) 从gib下载最新vision。
(2) 使用vs2010构建。
(3) 你会遇到的问题

#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

只需将代码从类中取出，重新构建。
(4) 你会生成glui.lib.
(5) 使用glui.lib和glui.h
