rtems-4.11 toolchain (lm32 one) builds fine for me under Mac OS X 10.6
(Snow leopard)

I wrote a Portfile for MacPorts to ease installation of lm32-rtems
toolchain :

http://trac.macports.org/ticket/30767
http://trac.macports.org/ticket/30766

It works for me (and enables me to generate a .dmg installation file in
one command)

The only problem I had with gcc 4.5.2 is that -arch= was passed to Apple
gcc during compilation of libgcc which is not supported and it made the
compilation fail at the exact same point in the logs posted in the
original e-mail from Eric Norum.

This issue (-arch) is fixed by the following files in the gcc Portfile :

# the generated compiler doesn't accept -arch
if {[info exists build_arch] && ${os.platform} == "darwin"} {
     configure.cc_archflags
     configure.cxx_archflags
     configure.objc_archflags
     configure.pre_args-append --build=${build_arch}-apple-darwin${os.major}
}

I thought it was the same issue, it seems it is not.

If I can do something or test something that can help, tell me :)
