devkitPro

Hi
I am trying to compile very basic example - helloworld using DevkitPro and Programmers Notepad for Wii
[AMD Sempron mobile processor, Win XP SP2, fresh install of DevkitPro]
I got this error: I modified wii_rules ::
MACHDEP = -DGEKKO -mrvl -mcpu=750 -meabi -mhard-float
like:
MACHDEP = -DGEKKO -mhard-float

but still I get this error:
cc1: error: invalid option `cpu=750'

When I tried to compile the same code at my computer at work everything was fine...
I am sure that all paths [msys, devkitpro, devkitppc ...] are correct

What should I do???
How can I detect correct compiler flags?

I'm certainly no expert, but I had some trouble with environment variables myself, and since you say you've checked them yourself, I have to ask if any of them contain C:\. Because DevKit doesn't like C:\, it likes /c/.

Another potential problem I can see you having is that, if you do any other programming, you may be calling the wrong make. I always specify the fully qualified path to the make that comes with DevKit, just to be sure I don't end up with any errors that way.

Good luck.

Somehow you're managing to make gcc use the wrong compiler, I suspect you have GCC_EXEC_PREFIX set in your environment. Delete that variable and try again ( after replacing the original wii_rules ).
