You're right!
In addition to setting GCC_DEFAULT_VERSION to 4.7, one also needs
to adjust the following in Mk/bsd.gcc.mk:
. if ${_USE_GCC} == ${GCC_DEFAULT_VERSION}
_GCC_PORT:= gcc
. else
_GCC_PORT:= gcc${V}
. endif
The most correct way of doing this would be replacing the first line by
. if ${_USE_GCC} == 4.6
yes, this solves my problem, thank you.
However, it's not portable.
When the default is no longer 4.6,
but, say 4.7, then one would have
to change this to 4.7, right?
I understand that one should not just
mess with bsd.gcc.mk at will, but would
be great if only a single change was
needed for situations like mine.
Thank you
Anton
That should then do the right thing; or you could just remove everything
except for
_GCC_PORT:= gcc${V}
Either should work.
(I'd love to update GCC_DEFAULT_VERSION to 4.7 one of these days; is
the cluster sufficiently recovered for a test run?)
