Yeah, this is a completely invalid makefile. You need some tutorial on writing those.
View ArticleComment by HolyBlackCat on How to static link SDL library with gcc?
When linking libraries statically, you must also statically link all their dependencies. Try running pkgconf --libs --static sdl2, this should give you the correct flags (or pkg-config instead of...

You should tag your programming language too, for better visibility.

Show the output from file libSDL3.so.0. Maybe it's a broken symlink?

Make will never run a target more than once. I can instead recommend generating all your targets using foreach and eval, and using that to add common code to them.

Operators should always be in namespaces where ADL can find them, otherwise they don't work reliably. This means that it's not possible to add operator overloads for std::vector<int>, since...

...You're missing -Iinclude/SDL2, and all other compiler/linker flags needed to use SDL2. This is unrelated to makefiles. Also your stated directory structure doesn't match include/SDL2/SDL.h, where's...

Please always tag c++, not just c++XX alone. Also please don't add line numbers to code, we want to be able to copy-paste it.

Last time I checked, you couldn't have tuples with more than 1-2k elements. Check how many elements your compiler can handle.

@user12002570 Are you saying that typedefs are not instantiated before the first use? Okay, but it works everywhere, not only in typedefs: gcc.godbolt.org/z/3noqYPGP7

Everything else aside, not omitting includes is customary (and good manners). We don't want to add them every time we copypaste the code from a question to test it.

Never happened to me. We're going to need a minimal reproducible example (your directory structure, compile_commands.json and/or Clangd config, etc).

You need to start lifetimes of individual array elements using placement-new (when resizing the vector), and destroy them when the vector dies (by manually calling the destructor).

@463035818_is_not_an_ai I don't like that duplicate and am tempted to reopen this question. SDL is notoriously weird in its handling of main (does #define main ...) and what not, and I don't even know...

What's wrong with keeping that std::string as a long-term storage for the characters? Why do you want to copy them elsewhere?

This is not how C++ works. All variable names are fixed at compile-time, you can't use a runtime string as one. After a program is compiled, variable names disappear completely.

This is usually caused by having g++ of an older version than gcc. What does gcc --version say?
