If you don't want to wait for the toolchain to build, you can use http://autobuild.buildroot.org/toolchains/tarballs/br-arm-basic-2013.05-1.tar.bz2 as an external toolchain. It's a basic ARM uClibc toolchain (with no option enabled: no WCHAR, no largefile, no IPv6, no RPC, no locales). > > 2) The libunwind code seems to contain some architecture-specific > > code.

No, you shouldn't abandon the process. Your contributions are very welcome! I think you're very close to have something that can be merged, just keep sending new revisions of your patch that takes into account the comments from contributors. > It is no skin off my nose whether it gets put into BuildRoot, I was > only pushing it back as I didn't know it was there until someone else > I work with pointed out that this *seems* to be the basic library GDB > is based off of, thus could be useful in our embedded system. Yes, it would certainly be useful.
