Comment by HolyBlackCat on Make bitmask from enum definition
Add mask = (1 << 18) - 1 to the end of the enum, and you're done! Or better mask [[maybe_unused]] = (1 << 18) - 1.
View ArticleAnswer by HolyBlackCat for MSYS2 Clang++ produces error with filesystem library
After some testing, this is a bug in libstdc++, the GCC's C++ standard library. It's already fixed in the newer versions.This happens any time you do std::filesystem::copy("file", "directory"),...

"Convertible to some T matching concept C" is fundamentally impossible, the compiler isn't going to check all possible conversion targets."Decays to a type matching concept C" is possible, but not with...
View ArticleComment by HolyBlackCat on C++ emscripten setup
First you need a proper build system, e.g. CMake (I assume you're using VS projects right now). Then use emcmake (see Emscripten manual). Making VS compile with Empscripten probably isn't trivial, I'd...

Don't add "solved" to the title. You should just delete the question (or self-answer it, but you can't do it in the staging ground).

@JodyHagins My point is that no, compilers are not moving in this regard, they are being very very conservative. People widely rely on this stuff working.

Sounds like a job for semantic highlighting. I don't know if the stock C++ plugin can do it, but Clangd surely can.
View ArticleComment by HolyBlackCat on GLADloadproc: what exactly does it do?
Are you asking how to read complex typedefs? The rest is fairly straightforward, the address returned by that function is saved into a variable (of a function pointer type).

Can you tell what exactly the (perceived) problem is here?

Sometimes it figures it out and still installs the packages, supposedly from other sources (look at the end of the output). Sometimes rerunning the command helps. If neither works, go ask your network...
View ArticleComment by HolyBlackCat on Can't link to SDL3 using MinGW
This happens when you use x32 libs with an x64 compiler or vice versa. I recommend installing prebuilt SDL3 and MinGW from MSYS2, those are guaranteed to be compatible.

Boost.preprocessor probably.

Can you prepare a minimal reproducible example. It looks like it should work.

This doesn't do much on Windows. This is a good idea, but not doing this will at worst give argv in non-UTF8 encoding I think?

What is a "code server"? And yes, you just install a compiler (Clang) and a text editor (Nano).

@Rud48 Huh? I'm explaining why this isn't feasible too implement, because of language limitations. "Your code in CE" What code, I didn't post any.
