Compile error using QT

[Kraj413]

Making compile error in Tutorial_204_Viewer_Qt and Mapple using QT when using Visual Studio 2022

error C2065: 'GL_MAJOR_VERSION': undeclared identifier error C2065: 'GL_MINOR_VERSION': undeclared identifier error C2065: 'GL_RENDERBUFFER_SAMPLES': undeclared identifier error C2065: 'GL_MAX_SAMPLES': undeclared identifier error C3861: 'glDepthRange': identifier not found error C3861: 'glDepthRange': identifier not found

• OS: [e.g. Windows 10
• Compiler MSVC2022
• Debug and release?
• QT version: 5.6.3

I see GL_MAJOR_VERSION is in glew.h but once I include that header file by #include <easy3d/renderer/opengl.h> or directly including glew.h, getting other compile error.

I will appreciate if anyone can help me to compile two projects successfully.

Can you post your complete CMake log and VS compilation log here? I suspect that an unsupported Qt was used by your visual studio.

[Kraj413]

Thank you for your feedback. I used Qt 5.6.3 and VS 2022. CMakeConfigureLog.yaml.txt

[LiangliangNan]

That is not the log of the CMake process of the project. Besides, please also attach the VS complication log.

Nowadays it is quite common multiple Qt versions exist in a machine and these log may tell us which Qt was used.

[Kraj413]

Actually I am not good at cmake. I will appreciate if you let me find the right cmake log. Here is VS log. Tutorial_204_Viewer_Qt.log

What is the prefered QT version? Testing with Qt5.12.7, it makes no compile errors but so much link errors regarding Qt.

[LiangliangNan]

Is your Qt targetted for (or built by) VS 2022? Your used Qt libraries must be compitable with your compiler. The path to the Qt libraries on my tested machine is D:\dev\Qt5.15.2\5.15.2\msvc2019_64\lib. On this path you see msvc2019_64. This means the libraries are for VS 2019 (and they are typically not compitable with other VS versions).

Again, nowadays it is quite common multiple Qt versions exist in a machine, you must make sure you used the intended version of Qt and the existing Qt libraries are compitable with VS 2022.

I need the complete log (not part of it), which is the output of VS when you compile/build the project. On my machine it looks like vs-log.txt.

Similarly, the CMake log is the log information CMake produced when you configure the project using CMake:

  Tutorial_203_Viewer_wxWidgets requires wxWidgets but wxWidgets was not
  found.  You can set 'wxWidgets_ROOT_DIR' to the root directory of wxWidgets
  (e.g., 'D:/dev/wxWidgets-3.2.1') to help CMake find wxWidgets.  Without
  wxWidgets, you will still be able to use all other features provided by
  Easy3D.

I will close this issue because it is not related to Easy3D bug or issues, but programming skills and use of develpment tools.

Many thanks for your help. You are right I installed the other Qt version 5.15.2 and Easy3D is working well now.
