Re: [Mingw-users] undefined reference to `GetComputerNameExA'

[Greg J. <gv...@gm...>]

The headers are there, in winbase.h; here is a collection of how I compile:

        -lshlwapi  -lws2_32 \
        -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32
-luuid -lcomdlg32 -ladvapi32

some of that won't be needed, of course.
