I'm trying to build Qt 5.15.2 from source on Windows 11, using llvm-mingw. The configuration succeeded, but building (with mingw32-make) kept giving error "invalid argument" at "llvm-ar" line (picture below).
I tried to test "ar --help" but it also gave the same thing, so I consider the error came from ar itself, but I don't know why. Btw, to avoid special characters all the paths don't have any spaces.
Anyone could give me some advices?
