Re: Succes using crosstool on Mac OS X

[David Wuertele <dave-gnus at bfnet dot com>]

Hi Martin, thanks for posting your OS X experience!  I too am trying
to get crosstool to work on OS X, and I have a few questions.

On my OS X 10.3, I already have cvs, rsync, libtool, awk, and sed.
Was there a specific incompatibility that motivated you to install
these using fink?  Or did you just not have them on your system?

I got past this by just removing the "as --version" check from the
configure.in file and running autoconf.

I don't understand how this solves the problem.  Doesn't "as" have to
be a native as?  How would using a powerpc assembler allow you to
build a cross compiler that actually runs on the Mac?
