[gentoo-user] sys-devel/gcc-4.6.3 fails with Bootstrap comparison failure!

[gentoo-user] sys-devel/gcc-4.6.3 fails with Bootstrap comparison failure!

[Mick]

I'm trying to run revdep-rebuild --library '/usr/lib/libmpc.so.2' &&
rm '/usr/lib/libmpc.so.2' following the elog message after I updated
dev-libs/mpc-1.0.1. (I think).

Anyway, one (rather ancient) box continuous to fail with:

sys-devel/gcc-4.6.3 was built with the following:

Any ideas how I can complete this emerge?  Last time it was emerged
(whenever it became stable in portage) I don't recall having any
problems.

Thanks Alan.  I failed to find it when I looked, which can only mean one thing 
... that I'm going blind!  LOL!

The strange thing is that I didn't have a problem emerging it last time.  
Anyhow, I've just changed the CFLAG -march=pentium3 and emerging it again with 
-march=i686.

Thanks again.

I know the feeling ...

Searching bgo for "gcc" is just painful, so I added the error you posted
to the search string:

gcc Bootstrap comparison failure!

Often times the searchstring makes all the difference and searchstrings
are an advanced technology therefore indistinguishable from magic. If
they were easy and not magic-like, they would be insufficiently advanced
for our needs (with apologies to a certain mr Clarke)

:-)
