MAME Compiling Error

[MADsix]

hi,

i've been trying for hours now to apply the hi score diff patch to mame 0.139.
i am sure that i have all the correct files, however when using mame compiler 64 1.20 i always get this error message:

Compiling Mame...
Using Parameters OSD=windows TARGETOS=win32 -j3 ARCHOPTS=-march=pentium4
mkdir.exe -p obj/windows/mame
process_easy: DuplicateHandle(In) failed (e=6)
process_easy() failed to launch process (e=6)
mkdir.exe -p obj/windows/mame
Counted 3 args in failed launch
Finished!

nothing changes if i check or uncheck the boxes and i have tried this both on a win xp and a win7 system.
the same happens with mame 0.140. i only got it to work once with 0.119 but then mame crashed when loading up a game ...

i really don't know what to do and i hope someone can help me out. also if someone could just compile it for me i would be very grateful (if asking for this is not allowed, please ignore).

thanks in advance!


edit: i forgot to add that i tried the manual compiling method too --> same error

Appears like you're using a cusom MinGW install. The one that comes with Mame compiler has been modified so the output can be redirected to the window. Without it you will get errors like that.

You should also try using the auto optimize option.

Right! My bad, I got so confused that I thought I'd had to install MinGW separately. Works fine now. Thanks a lot!
