I believe those "-W1" options above should be -Wl (that is, dash double-yew ell, not dash double-yew one). Also, if you use gcc to do your linking (as suggested) and if your specs file is correctly set up (as it should be if everything else is working) then you could use -mwindows to do the same thing (and get those extra libraries too) e.g. gcc -o hello.exe foo.o bar.o -mwindows If you are using 0.1.4 of Mingw32 instead of the latest snapshot (the versions included with Jan-Jaap's versions of GCC or Mumit Khan's versions of EGCS also use -mwindows) then you should use -windows, though I suggest you edit the specs file and replace all occurences of %{windows: with %{mwindows: and use -mwindows to be consistent with Cygnus and later Mingw32 releases on this. Also, not specifying the entry point with -e _mainCRTStartup should not give you a warning with the latest snapshot of Mingw32 (or version 0.1.4 either if I remember correctly). Even if you do get the warning (could not find entry point _WinMainCRTStartup or something like that) it is harmless in all the cases I am aware of. -- Colin Peters - colin at fu.is.saga-u.ac.jp -- Saga Univ.
