I tried 3.11-rc3 yesterday on my RP3440. It works, but has acquired a

There is no file named conftest present after emerge, so it must have
been some temporary program.

Those warnings are uncritical - but you should update binutils.
See: http://permalink.gmane.org/gmane.linux.ports.parisc/3834

I did a full deep emerge update on Gentoo taht also installed binutils
2.23.1. I will look for further messages when there is something new to upgrade - during the same upgrade, it got messages about locale- archive.


conftest is the name of the test program used by configure. It's output log is in config.log in the directory
being configured.

As I said, the above messages typically occur when a core dump occurs. This is because the core dump flushes all the mappings that the application has and the kernel detects the inequivalent aliases. Probably,
this occurred twice in the package being configured.

It is easy to generate inequivalent aliases with a custom linker script. It's quite likely they are being generated
by the eglibc package but that's just a guess.
