djgcpp cross assembler for PPC

Wed Dec 16 06:11:00 GMT 1998

Hi Tom,

Yes,  what I have been trying to do is find some GNU-based cross compiler
for PPC (PPC821) running in an embedded system but with tools hosted on
Win95/98 or NT platform.  The djgcpp cross compiler has almost filled that
need (I have verified it properly does everything Big Endian but not so
sure about Little Endian). But I cheated - the www.objsw.com site has
prebuilt binaries for PPC (and other processors) for Windoze systems.

I am still trying to get the Cygnus B20.1 tools to create a PPC cross
compiler but no luck so far, I keep bombing out in "configure"!!  Maybe I
should just try the mingw32 side of things....

Are you building the cross compiler for and embedded system?  I'm curious
because I've been tryingto build a cross-compiler for a PPC based RS/6000
running AIX and I've been having no luck.

Peace....

Hi,
I am having problems with the cross assembler (djgcpp as downloaded from
the www.objsw.com/download site) for the PPC cross assembler and the
little-endian runtimes.
When compiling a small test program the assembler seems to be creating a
big-endian object file which then links to the little-endian libs and
fails.
Is it possible that the as built for this was built assuming big-endian?
Thanks for info,
Michel
