Title: Building a Cygwin version of GCC that targets the PowerPC...






Does anyone know of, or have a pointer to instructions on how to build the latest GCC on Cygwin that targets a PowerPC processor?  IE:   GCC hosted on Windows that builds PowerPC .elf object files...

Thanks,


Adrian

just spotted an errata for the above:
the line

'get cygwin, and source for binutils-2.10 gcc-2.95.2-core, gcc-2.85.2,
newlib-1.82'

should read
'get cygwin, and source for binutils-2.10 gcc-2.95.2-core, gcc-2.95.2,
newlib-1.82'

(just in case anyone got confused ;)

This is how I unzipped the packages:


gzip -dc package_name.tar.gz | tar xvf -


Also, the "core" and the non-core package all got unzipped into the same directory... Is this bad?


Thanks,


Adrian

did you extract the tar.gz's with tar? if you used winzip all the soft links
will be broken and files will appear to have gone missing.


(i'll add this to my instructions ;)

true, but I've never been able to figure out a simple way to configure it so it
just builds a core - If anyone knows a straightforward way, please let me know
;)
This is the just the way I learnt to do it, and it's pretty foolproof.

Hmm. nope. here's my output from mount

$ mount
Device              Directory           Type         Flags
C:\cygwin\bin       /usr/bin            user         binmode
C:\cygwin\lib       /usr/lib            user         binmode
C:\cygwin           /                   user         binmode

I get the following error when typeing in "make" for the gcc-core section of those instructions you gave me.. Any idea what is wrong here?:

  A couple of things jumped out at me from that text file:-

>get cygwin, and source for binutils-2.10 gcc-2.95.2-core, gcc-2.85.2,
>newlib-1.82

  I don't understand this. Surely gcc-2.95.2-core is a subset of what's
in gcc-2.95.2, so that step should be unnecessary? (And I'm assuming that
85 is a typo for .95)

  The reason for this would be that the drive on which you're doing
the build is mounted in text mode, most likely. If you have a binary mode
mount point in your cygwin setup, you can create a build directory there,
and it should work fine.

  This will come in handy! Thanks!
