OpenGL/glew 未解析的外部符号

Question

我遇到了 glew 和链接器错误的问题。我有：

1. 把glew32.dll和glew32d.dll放到system、System32和SysWOW64中
2. 将 glew.h 放入 GL 文件夹中
3. 将glew32.lib、glew32d.lib、glew32s.lib放入Lib文件夹中
4. 将 glew32.lib、glew32d.lib、glew32s.lib、glut32.lib、opengl32.lib 放入附加依赖项中
5. 将 GLEW_STATIC 放入预处理器定义中

但是，我仍然收到以下错误：

1>project2.obj : error LNK2001: unresolved external symbol ___glewGetProgramInfoLog
1>project2.obj : error LNK2001: unresolved external symbol ___glewGetShaderInfoLog

1>project2.obj : error LNK2001: unresolved external symbol ___glewUniform1f
1>project2.obj : error LNK2001: unresolved external symbol ___glewUseProgram

我有什么明显的遗漏吗？还有什么我可以尝试的吗？谢谢。

如果您使用的是静态库 glew32s.lib，则需要定义预处理器标志 GLEW_STATIC 以便解析符号。

您可以在源代码中使用

#define GLEW_STATIC

或将其添加到项目的预处理器指令中

Project Properties > C/C++ > Preprocessor > Preprocessor Definitions

如果你之后还有未解析的外部符号you may also need to add opengl32.lib as an additional dependency for the linker.

如果在此之后您仍然有未解决的有关 glew 的符号，请确保您实际上已将 .lib 添加到链接器搜索的库目录中。您可以将其添加到

Project Properties > Linker > General > Additional Library Directories
