C++20 not working (no u8path, no u8string)

[UnrealKaraulov]

And crash at

// OneDrive
auto oneDrive = std::make_unique<FileTreeNode>(_wgetenv(L"OneDriveConsumer"));
m_treeCache.emplace_back(std::move(oneDrive));

because _wgetenv returns NULL

[UnrealKaraulov]

Also crash at

		glGenerateMipmap(GL_TEXTURE_2D);

Hi @UnrealKaraulov, can you tell which os are you working on? And the example requires opengl, did you install them on your system?

Visual Studio 2022

OpenGL 3.3

I think probably the env for onedrive on your machine is different, probably just "OneDrive". Can you check what is the env variable for Onedrive on your machine? You can follow this guide to see if it is there.

glGenerateMipmap(GL_TEXTURE_2D); crashes

This probably due to the incorrect layout of data passed to the glTexImage2D, can you try check what are the real data format on your machine?

Sorry I have only one Windows machine so I can't test all situations, glad you brings these up.

No 'OneDrive' variable on my Windows 11

And if I choose C++20 for build, I got error 'in C++20 removed u8path u8string', now just string()/wstring() and path()

Ummm that's interesting, that new feature is disable by /Zc:char8_t- in the CMakeLists.txt, are you using MSVC on Windows?
