Might be related to #30054

Why did gcc_select fail to install? Please attach its main.log file.

Replying to ryandesign@…:

Why did gcc_select fail to install? Please attach its main.log file.

I'm pretty sure it was to do with the macports user not existing (see #30054). Once I edited macports.conf to set the user to 'root', I was able to get by this step.

However the original main.log file for gcc_select is in the bug description above.

[ryandesign (Ryan Carsten Schmidt)]

Oh, that's all of it. I see. "4294967295" is a pretty large user id or group id -- in fact that's the largest unsigned 32-bit integer, so that's probably an error somewhere.

[jmroot (Joshua Root)]

Could we have debug output please? The error isn't happening in the portfile context so it doesn't show up in the log for the port. The big number is actually -1 (converted to unsigned), which is what name_to_uid returns when you give it a nonexistent username. But the call to that proc should only happen if privileges had been dropped previously.

Should be fixed by r80229, reopen if not.
