Reproducible: Always
Steps to Reproduce:




I had to add the following to the patch so that crossdev.sh would build anything
without the '-u' flag.  GCC 3.3.3 is broken for the avr target on Gentoo.  See
bug 46401 ( http://bugs.gentoo.org/show_bug.cgi?id=46401 )

We still need an ebuild for avr-libc, but avr-gcc and avr-binutils can go away.

please :-)

grovell grovell :-). Please Joshua show us how good your stuff is.

[Comment 3 Radek Podgorny 2004-11-03 05:34:42 UTC]

Add to portage, please...

[Comment 4 Pavel Semerad 2004-12-03 07:19:35 UTC]

And what about adding support not only for avr, but for generic gcc target,
which will compile only kernelgcc. I did this patch and compiled
mips-dec-ultrix target as I was asked for :-) I will compile avr too, because
I am using it.

<=crossdev-0.4 is no longer supported ... please upgrade to crossdev-0.9 and if
you're still having problems, re-open the bug and re-assign to [e-mail]
