C++ 在Windows上构建Qt 5.9项目时出现OpenGL链接错误

我正在尝试使用MSVC2017 64位并使用预构建的Qt二进制文件在Windows上构建Qt 5.9项目。 该项目依赖于创建自定义项，该自定义项用作生成原始OpenGL调用的渲染后端

在尝试构建时，它似乎链接到系统版本OpenGL（Windows上为1.0），并返回大量未解析的外部符号，如果我没有弄错的话，这些都是OpenGL 1.0上不存在的函数。您可以在下面看到未解析符号的列表

我已经尝试过各种解决方案，比如将

LIBS+=opengl32.lib

添加到我的

.pro

文件中，但它一直链接到系统版本。GPU驱动程序更新到最新版本。由于每次修改

.pro

时都运行

qmake

，因此没有重新生成makefile的问题

如何链接正确的OpenGL版本以使编译成功返回

它不是的副本，我在每次编辑

.pro

文件后运行

qmake

，如上所述。

看起来您没有链接现代OpenGL函数的实现。opengl32.dll不提供这些功能。您可能想使用一些辅助程序库，如glew。我尝试使用glew，但没有效果，它不断出现相同的错误。它已被修复，正确的库未链接。有关更多信息，请访问Github。
