Please bear with me - in the past, I've dabbled with C and assembly, but
that was long ago, and I never really had to mess with configuring much
(it was a hobby).  But now, I want to put more effort into learning
assembly (still as a hobby, though).

I don't know what you mean by 'configure triple'.  I'm using a PKGBUILD
at https://aur.archlinux.org/packages/insight/ - you can view the
PKGBUILD from the web page, if you like.  If you look there, you might
also look at the comments at the bottom of the page, as well as this
thread, started by me in the forums:
https://bbs.archlinux.org/viewtopic.php?id=157819

AFAICT, There seems to be a bug in gcc-4.7.2 with a "struct siginfo"
that should be "struct siginfo_t", per this page:
http://sourceware.org/ml/libc-alpha/2012-03/msg00414.html

At any rate, other users get stuck with errors like this:
"/home/briphi/builds/gcc46/src/gcc-4.6.3/libgcc/../gcc/config/i386/linux-unwind.h: In function âx86_fallback_frame_stateâ:
/home/briphi/builds/gcc46/src/gcc-4.6.3/libgcc/../gcc/config/i386/linux-unwind.h:138:17: error: field âinfoâ has incomplete type
make[3]: *** [unwind-dw2.o] Error 1"

This applies to me in trying to build older versions of gcc (the snippet
above applies to building gcc-4.6.3) and the same applies to configuring
'insight'

With my limited knowledge and in using the PKGBUILD at
aur.archlinux.org, I'm pretty much stuck to using the source provided in
that script, which is 6.8.1a from sourceware.org.  I've tried to monkey
with the source line here, adjusting the first md5sum as needed, but
didn't get any where, due to the linux-unwind.h error above.

I have a dual-boot system with Ubuntu 12.10. Would you mind explaining
what I should do to build from source on Ubuntu?  So far, I've tried
uncompressing the source, and compiling from an alternate directory
using just "../src/configure", but that gave me the following errors:

config.status: creating po/Makefile.in
config.status: executing depfiles commands
config.status: executing libtool commands
config.status: executing default-1 commands
config.status: executing bfd_stdint.h commands

Here is my gcc --version output from ubuntu:

brian@ubuntumachine:~/builds/insight$ gcc --version
gcc (Ubuntu/Linaro 4.7.2-2ubuntu1) 4.7.2

Many thanks for the reply and being willing to help!

And regarding building gbd, will I be okay doing this in a /home/user
directory?  I don't want to screw up my Ubuntu (or Arch) install, so I'm
a bit hesitant.

Kind regards,
Brian
