If you follow the link below: https://dlang.org/dmd-windows.html#switch-L
It's written: " -Llinkerflag pass linkerflag to the linker link.exe , for example, -L/ma/li "But at least on Windows, you need to put a space between -L and the PATH. Which It's weird, since with "-I" flag you don't need any space.
It took me 30 minutes until I find why my program wasn't compiling. (I found the tip on a forum elsewhere).
Is this a bug or a mistake? Bubba.
