glew - 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. 将 glew32.dll 和 glew32d.dll 放入系统，System32 和 SysWOW64
2. 将 glew.h 放在 GL 文件夹中
3. 将 glew32.lib、glew32d.lib、glew32s.lib 放入 Lib 文件夹
4. 将 glew32.lib、glew32d.lib、glew32s.lib、glut32.lib、opengl32.lib 放在附加依赖项中
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

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。

您可以在源代码中执行此操作

#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

如果之后您仍然有未解析的外部符号，您可能还需要添加opengl32.lib作为链接器的附加依赖项。

如果在那之后您仍然有关于 glew 的未解析符号，请确保您实际上已将其.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
