Hi, all,
I have 5 up-to-date gentoo machines, all of them running gcc-4.1.1-r3.
On 4 of them, emerging libstdc++ proceeds as one might expect, just
installing
the current version of libstdc++ for gcc-4.1.1. But the 5th machine does
something quite different. Why?
On the 5th machine emerge -pv libstdc++ gives this output:
[ebuild NS ] sys-devel/gcc-3.3.6-r1 USE="fortran gcj gtk (-altivec)
-bootstrap -boundschecking -build -doc (-hardened) -ip28 -ip32r10k
(-multilib) -multislot (-n32) (-n64) -nls -nocxx -nopie -nossp -objc
-test -vanilla" 23,534 kB
[ebuild N ] virtual/libstdc++-3.3 0 kB
Why should it install gcc-3.3.6-r1 for machine 5? That doesn't seem to
be necessary for
machines 1-4.
I've tried running emerge -pdv libstdc++ on all machines to get debug
info, hoping that it would
enlighten me, but it doesn't - perhaps that's my shortcoming rather than
emerge's... For what
it's worth, the first few lines of output from emerge -pdv libstdc++ on
the machine that wants to install gcc are:
myaction None
myopts {'--pretend': True, '--debug': True, '--verbose': True}
These are the packages that would be merged, in order:

and the first few lines from machines that don't want to install gcc are:
myaction None
myopts {'--pretend': True, '--debug': True, '--verbose': True}
These are the packages that would be merged, in order:
