This project can run under Windows with msys2 and gcc

[asmwarrior]

Hi, I have just tried this project. Looks good!

I'm testing a very simple hello world project under: Windows 10, Code::Blocks IDE, msys2. Note that msys2 supplied many packages, include: freetype, glfw3, flew, opencv.

Here is the screen shot:

I'm not good at CMake, I can only supply Code::Blocks project files.

The above image is my another test to run the test file: examples\graph1.cpp.

When I start the program, an ampty window will first pop up, and I need to wait a few seconds to see the actual graph inside the window, I'm not sure this is by design, I see it also happens in the "hello world" sample code.

I see an error message in the console window, see below:

This message happens in many test cases.

Hi! Thanks for experimenting with the code on Windows. I'm glad you had some success.

The delays you report between window and graphics are not expected, so that's definitely an issue. I wonder what's happening...

The error about failing to make the context current may well be related. you could experiment with Visual::setContext - perhaps theres a short time with this platform during which the GL env is not ready.

Would you like to contribute build instructions for msys2?

I can help, but I'm not good at cmake. In-fact, I'm good at Code::Blocks.

I have a change to my fork: under msys2+gcc, I have to comment out the header files, because I have no such header files, but the build still look OK

With this change, I can build your project under msys2 and mingw64 gcc.

Also, here is the Code::Blocks cbp file content:

You can see the include paths in the cbp file, also you can see the linker options in this cbp file.

Thanks for the info.

Closing this issue as I've incorporated the discussion into the code now.
