@dusty storm Your compile command is incorrect

If you send it in text I can better point out why

[sterile tulip]

why did you write c++ after g++?

It comes down to how you configured that extension then

g++ c++ 17.cpp -o c++ means take source code files "17.cpp" and "c++" and output an executable called "c++"

which doesn't really make sense, hence the error, and you also don't have a source file called "c++"

If you need to check if your compiler supports c++20 you can simply do g++ -std=c++20 someprogram.cpp

why did you write "c++" in the compilation line?

oh, I see, your filename has a space

but yes, if you had an old version of gcc that didn't know what c++20 was it would give you an error
