And did you set the -std=c++20

lusty oriole
#

/usr/local/opt/llvm/bin
/clang++ main.cc -std=c++2a

graceful forge
#

Ah clang

#

Holup

lusty oriole
#

no such argument

graceful forge
#

Standard C++ modules are enabled automatically when the language standard mode is -std=c++20 or newer

#

Which clang version

#

And i believe you need to name file .cppm

#

Instead of .cc

graceful forge
#

Huh wait

#

Nah they good

Check it out

lusty oriole
#

ok, I got it.
I think I need to compile the module first, and then use the module with main.cc

#

what the hell ?
