gcc7 @7.3.0: Selftests fail with "Illegal instruction: 4"

Reported by: chucko58 (Chuck Fry) Owned by:

Component: ports Version: 2.4.2
Keywords: sierra x86_64 Cc:
Port: gcc7

Description

'port install gcc7' fails repeatably on this MacBook Pro running macOS 10.12.6. The failure appears to be in the selftests. This copy of MacPorts was built w/o sysadmin privileges, and we are running some funky security stuff here, so this may be unique to our configuration.

The complete build log (with tracing enabled) is attached as a gzipped file. The key part of the log:

We have an old version of XCode installed on this machine. I am going to pursue updating it with our local system support people.

Apparently that error indicates your processor is trying to run instructions that it can't understand:

<https://stackoverflow.com/questions/14268887/what-is-the-illegal-instruction-4-error-and-why-does-mmacosx-version-min-10>

Some instruction set has become enabled that your processor is not able to run, some linked library like gmp built on another processor but moved onto your machine somehow, some misconfiguration in mmacosx-version-min, etc?

The problem apparently resulted from restoring a copy of MacPorts from a backup of a 2015 MacBook Pro to a 2010 model. Rebuilding from scratch resolved the issue. Please close this ticket as invalid.
