This is illegal if you later provide a different definition of CTest.

What is your OS and compiler? What library are you installing?
View ArticleComment by HolyBlackCat on C++ compiles but doesn't run (VSCode only )
You don't need -lstdc++fs in modern GCC. Also try compiling and running directly from MSYS2 terminal.

@DominicGrenier You don't need any of that (patching SDL). When MinGW says "undefined reference to WinMain", it will happily accept eitherWinMainormain.

@PauloCarvalho I was going to suggest submitting a bug, but you already did that. :) If you have time, I'd recommend trying to reduce this error to a minimal example that doesn't depend on VTK (or...

You need to sit and think about it. You're stuck for a specific reason, figure out what is it (what exactly you have difficulty with?). We can't help you because we have no idea what game you're trying...

Why exactly four? Is this a homework/exam question?
View ArticleComment by HolyBlackCat on Import C single header library in C++
Report it as a bug to the library developers. Keeping C libraries compatible with C++ is usually desired.

n = name; h = health; a = attack; this looks backwards. You would've noticed this if you used your debugger.

Did you build SDL2 yourself or install from the package manager? Self-built versions will sometimes do this if you fail to install the required dependencies before building them (the list of packages...
View ArticleComment by HolyBlackCat on Weird behaviour with std::vector in c++
Modifying a container while iterating over it with a ranged-for loop results in UB. Anyway, it seems you want std::map rather than std::vector (but debugging the issue with vector probably has learning...

@cpprust There are two different things here: bit order in bytes (on hardware level), and the order of bitfields (as chosen by GCC). The former can't exist in the first place, because there is...

You don't need the placement-new, this reproduces on a plain array: godbolt.org/z/Y5Pc3TKvT (on both Clang and GCC). Interestingly, I can also repro on non-thread-local array (but only on GCC, Clang...

Under common sense this is a false positive. I'd silence it with a pragma and move on.

Unsure if auto is supposed to work or not, but the fact that it starts working when you change fun() to the second snippet is definitely a bug.

Compilers don't optimize away function calls with side effects. If it's get_tzdb_list that initializes the database, then (void)std::chrono::get_tzdb_list(); is enough.

I think some linkers (LLD?) don't have this limitation. Otherwise not sure why it worked for you before. I don't really want to write an answer, this is likely a duplicate.
