> Mike, are you using llvmgcc or normal gcc from toolchain4 at present? If
normal gcc, then I'd recommend that you guys build from the latest of the
cctools-llvm branch to get the latest fixes (llvmgcc is disabled at
present, IMHO it was never very reliable, even the official Apple
binaries).
Normal gcc and yes, I am using the latest cctools-llvm branch.
> Georg, there's no reason to use darwin11 instead of darwin10. When I
started this work it was with a darwin11 SDK so it's purely a matter of
habit for me. The merge to crosstool-ng is being done by Yann Diorcet and
myself; I handle the darwin11 samples and he does the same for the
darwin10 ones.

feel free to base your version on i686-apple-darwin10 (e.g. flosoft's
MacOSX10.6.sdk) and the i686-apple-darwin10 sample instead.
That was actually the reason why I asked. We use already flosoft's
MacOSX10.6.sdk and I hoped to avoid using the 10.7 SDK to get a compiler
to use that one with the 10.6 SDK... Good.

Thanks I'll think about doing an own while I digest that whole system.

exact ISO and any scripts you use to prepare it for development? I will
then make a new VM.
The gitian build system is working with (at least) the current LTS
(12.04). I order to build the Mac TBB you do the following
{{{
git clone https://git.torproject.org/builders/tor-browser-bundle.git
cd tor-browser-bundle/gitian
make prep
}}}
Install all the stuff you are asked to and run
{{{
make prep
}}}
again until you have all the necessary sources (i.e. until |make prep|
does not give you any errors anymore)
Then do
{{{
./mkbundle-mac.sh
}}}
and it should give you (after a while) Mac TBBs in a new directory
(currently 3.0-alpha-4). Anyway, if you have issues with setting it up.
Just write me a mail and we'll sort these things out.

So I have found so far three issues (disclaimer: I am not sure yet if
there is anything you can do about as this might actually be things
belonging to the source packages used in building the compiler):
1) I hit intermittent GMP configure failures due to newly created files
being older than distributed ones. (log: cross_mac_gmp1) That is likely
due to the gitian build environment but it would be good to somehow avoid
that. I am wondering whether the reason here is some old version of GMP? I
have been building mingw-w64 from source for a while with a similar gitian
environment but never hit this problem.
2) 'groff' was missing (the check in the configure script is there but
although 'groff' is needed for building the script is not returning with
an error if it is not available) (cross_mac_build1). Installing the
necessary package probably solves the issue.
3) a Makefile.config(?) is missing? (cross_mac_build2).
Now, what bothers me most, though, is that Firefox 24 is not working with
a gcc4.2 anymore (at least Mozilla is saying that in the configure script
and I don't have a reason to doubt that). I am under the impression that
your cross-compilers are (by default) gcc4.2, no? If so, what are our
options here? Are there non-interactive ways to change the gcc version?
