Re: canadian cross error

Kai,
Yes, you're right. I didn't know which source files generated 
'Makefile' for 'go32-to-m68k-coff', but what I did, just deleted
all 'objective-c' in all created 'Makefile'.
It worked !!! Thank's again.
Now it comes to the last part ... convert the binaries to. exe's
and cope with DOS's 8.3 file name restriction.
I use package dosrel-1.0, downloaded from ftp.cygnus.com.
Well, this scripts also have bugs !!
The compiler which is used is not refer to sun-x-i386.
Created 'Makefile' will have something like this :
CC = i386-go32-gcc
......
So I just refer the compiler to sun-x-i386, but as it compile
'doschk.c', 'alloc.h' is needed. I couldn't find this 'alloc.h'
in anywhere, not in include from sun-x-i386 or GNU source code.
Where does this file hide???
