They seem to already know (some part of?) this, as shown by the last paragraph of the question.

This is usually fixed by reordering directories in PATH to make MSYS2 be first. In the (non-msys2) terminal, run echo $env:PATH to print the PATH and confirm that MSYS2 is first.
View ArticleComment by HolyBlackCat on System cannot find glfw3 even though it is installed
"instead using GLFW instead of glfw3" Do you mean -lGLFW? It should be -lglfw, I believe. "GLAD fails to initialize" This is a better error compared to "glfw3: no such file or directory", it means...

Works for me out of the box on MSYS2 GCC, without any compiler flags. Don't try to use MinGW with MSVC's headers, get a version of MinGW that directly supports headers you need.

Can a PCH be involved? Also try going to the VS settings and increasing the log level, maybe the compiler will tell you what includes those files.
View ArticleComment by HolyBlackCat on Gcc and clang reject move constructor with =default
I didn't downvote this, but eel.is/c++draft/dcl.fct.def.default#2 seems relevant, I'd quote it too. My current reading is that OP's =default should become =delete automatically in this case, but I...

std::allocator is an empty class, I don't understand why it has a custom copy constructor in the first place.

Function types can't exist without the return type. I highly doubt this was the intent, it looks like the new "T may be empty" wording only tries to handle conversion operators.

Clangd has this silly habit of inserting placeholders for function arguments. --function-arg-placeholders=false stops it.

If you have an rvalue expected and call .value() on it, you want it to return an rvalue, to be able to move from it.

@Gene You can't do this with std::allocator, or at least not directly. Allocator requirements force it to be copyable, and the copy must be able to free the memory allocated by the original.

This is makefiles 101. The makefile targets should be named after the files they produce, then they're not going to be re-run.

You can build in verbose mode and look at the compiler commands.
View ArticleComment by HolyBlackCat on Switch case: Return from impossible default case
"putting an assert at the end doesn't seems correct" Why not? Also if you only have two states, it sounds like a job for bool, not a enum, then you won't have this problem. Also I recommend not adding...
