Re: RPi build issue on OSX

[Nathan Plesnicher <nplez1 at gmail dot com>]

Hi Bryan,

I actually was able to get it working. It turned out that just
switching to eglibc 2_17 (the default for the RPi sample was 2_16)
fixed the problem when combined with my other patches to get the build
working on OSX.

For others trying to build this toolchain, the patches I had to apply
were as follows:

http://sourceware.org/ml/crossgcc/2012-05/msg00012.html
Need libintl linked in, and this diff did the trick. Not sure if the
ncurses and escdelay change is actually needed

http://sourceware.org/ml/crossgcc/2011-05/msg00094.html
(optional; only use if you are building gdb) Include the host expat so
that gdb works as expected

The following one actually needs to be applied to the eglibc source
that is downloaded...
http://sourceware.org/ml/crossgcc/2013-03/msg00109.html
Patch rpc/types.h so that it doesn't redefine the types on OSX
(already in sys/types.h)

I hope this helps someone in the future.

Nathan
