clang14 compiler error?

[queen forum]

Everything you need to see is below. In short, it’s failing to compile because of the experimental-library flag that I need for std::format. Not sure where to go from here

That's some old Clang. Are you forced to use it?

• for above. Maybe this version doesn't support the flag yet?

[queen forum]

It’s the version in Debian stable. I could upgrade but i dont want to go through the hassle just for a docker container. 😂

[outer thorn]

this CLang version is almost 2 years old.

The exact reason why I don't like Debian.

The packages are always so behind

[queen forum]

The exact reason I’m using that flag is because it’s what’s listed on cppref compiler support page. I doubt it doesn’t support it

[raw elbow]

https://apt.llvm.org/ should give you the latest Clang

It's a bit weird to want to use the latest features, but at the same time try to use them on an old compiler

Fair enough
