[kenneth.f.cunningham@…]

I just installed gcc5 on Snow Leopard without issue. I do have my Snow Leopard systems set up with the LibcxxOnOlderSystems variant, if that makes any difference to the process.

I did notice that your build log indicated gcc-5.3.0.tar.bz2, whereas I just built gcc-5.4.0.tar.bz2, so perhaps you haven't updated macports in a while?

As a suggestion, you might consider trying to

sudo port clean gcc5
sudo port selfupdate
sudo port upgrade outdated

and then try gcc5 again.

Replying to kenneth.f.cunningham@…:

I just installed gcc5 on Snow Leopard without issue. I do have my Snow Leopard systems set up with the LibcxxOnOlderSystems variant, if that makes any difference to the process.

All versions of gcc5 were built successfully on Snow Leopard by our buildbot, which is not using libc++, so that would not be the reason for the failure. (Chris is using a custom MacPorts prefix, which is why he can't use the binaries produced by our buildbot.)

The main.log contains five installation attempts. This should not happen with MacPorts 2.3.4 or earlier, but there is a bug with MacPorts trunk which does cause the logfile to fail to be cleared between attempts. Are you actually running MacPorts trunk, and not 2.3.4 as indicated? Please sudo rm $(port logfile gcc5) before cleaning and trying again per Kenneth's instructions above.

Also, please let us know what version of Xcode you have. If it's older than 3.2.6, please upgrade to 3.2.6.

Failing to get any additional information from the submitter for months and not being able to reproduce the problem, I'm closing this ticket as worksforme. If there are still problems, please submit a new ticket after updating macports & port definitions and after a clean attempt.
