libstdcxx is not building for me. main.log attached.

Can you please try this as a workaround:

It took a while but it worked. FYI, this was on a Mac Pro 2008 with 6 GB RAM.

I spoke too soon. Macports keeps finding linking errors and rebuilding it.

Please install libstdcxx using port install --no-rev-upgrade libstdcxx, run port -d -y rev-upgrade and attach the output.

This is fixed in llvm's ​r163761, so we'll just have to try future XCode releases to see when the fix makes it to us.

So... there have been a few XCode releases since then... has the fix made it to us yet?

[jeremyhu (Jeremy Huddleston Sequoia)]

Yeah, it's fixed in clang-3.2 and clang-3.3

So does this mean that libstdcxx can have --disable-bootstrap added back to it now? Bootstrapping it takes so long...

[jeremyhu (Jeremy Huddleston Sequoia)]

Right now, we can either bootstrap libstdcxx or add clang-3.2 as a dependency.

XCode 4.6 contains clang-425.0.24 which is based on llvm-3.2, but I'm not sure if it was before or after r163761 was merged in ... you can always just give it a try ;)

I'll take a look at this when I get some free cycles, but cpu cycles are MUCH cheaper than human cycles ;)

Would it be possible to add a variant to let the user choose? Or would that be too difficult considering that libstdcxx is already a sub-port?

[jeremyhu (Jeremy Huddleston Sequoia)]

I'm not a fan of compiler variants, so I'm going to say no for now. Please just be patient (or report back if clang-425 works).

[larryv (Lawrence Velázquez)]

clang-425.0.24 works fine, without bootstrapping.

[jeremyhu (Jeremy Huddleston Sequoia)]

great, thanks.
