msvc-wine VS NGL

Okay, I am trying it, but it does not exactly work out of the box. Do you remember how you got a hand on the MSVC libraries? I use https://github.com/mstorsjo/msvc-wine to download the MSVC toolchain using python, and then I simply wget this file https://raw.githubusercontent.com/llvm/llvm-project/main/llvm/cmake/platforms/WinMsvc.cmake, and call CMake like in the example the file has as a comment in the first few lines. I installed clang-tools-15 and lld-15 using apt. Does this sound somehow correct? I set all the paths correctly and I get a CMake Error "include could not find requested file: [...] //ClangClCMakeCompileRules.cmake", the error occurs while CMake is testing the C compiler if it works.

That's a nice lead! - I'll try looking into that more. If you have or remember some more details - please share! Thanks!

(One of my use cases is https://github.com/mstorsjo/msvc-wine - and invocation of `cl.exe` or `link.exe` taking 250ms at each is not going to be great (then again `cl.exe` can be made to input several .cpp/.c files, but it becomes more awkward to express that at the build level).

you can run the C++ compiler via wine: https://github.com/mstorsjo/msvc-wine

I guess I should try installing MSVC again one of these days. Maybe it's finally possible to setup a "real" Windows cross compilation build environment without msvc-wine.

I have a number of instructions on my Github pages here https://github.com/NCCA/NGL/blob/main/Windows.md whilst aimed at my own library the first part about installing Visual Studio and the basic setup will help.

code here https://github.com/NCCA/NGL

My Windows build is here https://github.com/NCCA/NGL/blob/main/.github/workflows/windows.yml I use vcpkg for installing 3rd party libs and the msvc-dev command from here https://github.com/ilammy/msvc-dev-cmd

Also I have just done an experimental version of my code that uses WSL2 (which supports graphics). You could try that. https://github.com/NCCA/NGL/blob/NewShaderLib/WSL.md

I also have a ShaderLib class that does similar stuff keeping everything in a static map (used to be a singleton class). Been using it for teaching for a number of years you can see it here https://github.com/NCCA/NGL

There are loads of edge cases and gotcha's as well. I have a full(ish) parser here with unit tests if it helps. (Note I use pystring to do the string processing). https://github.com/NCCA/NGL/blob/main/src/Obj.cpp unit tests here https://github.com/NCCA/NGL/blob/main/tests/ObjTests.cpp. May give you some ideas.

I use glfw in a number of projects here are my instructions for building my library https://github.com/NCCA/NGL/blob/main/Windows.md You should be able to use the bits you need from here to setup vcpkg etc. I suggest using the free Visual Studio community edition and installing most of the tools you need from there. After that install vcpkg and setup the paths required. (see my notes).

The one I use in my teaching is here. https://github.com/NCCA/NGL it also includes Math / Vec class which you may not need if you use something like GLM. Also this uses TDD so get into writing unit tests as part of it.

typically I just have classes with static factory methods to keep things together, usually with a std::unordered_map s_things; so I can create by name. This is an example for an OpenGL Vertex Array Object https://github.com/NCCA/NGL/blob/master/include/ngl/VAOFactory.h

I have several using a Factory design pattern here https://github.com/NCCA/NGL Checkout https://github.com/NCCA/NGL/blob/master/include/ngl/AbstractVAO.h for the basic structure, then I have different versions depending upon context and usage.
