Why don't recent GCC versions support compiling? (and some workaround)

[jorgicio]

As an Arduino developer, I use crossdev for creating toolchains (in this case, avr), but then I found recent versions (from 4.6.4) don't support cross-compiling, and I don't know why.

4.6.2-r2 has some errors at compiling, and I had (for a while) to use a pretty older version, 4.3.3.

 

Anyway, as a workaround, I had to download the Gentoo GCC ebuilds (that support toolchain), and all works flawlessly.

Also, I made a script for that.

#!/bin/bash

URL="data.gpo.zugaina.org/gentoo/sys-devel/gcc/"
#URL="sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-devel/gcc/"
PORTDIR="/usr/local/portage/cross-avr"
wget -r --no-parent --reject "index*" --quiet "http://$URL"
if [[ -e "$PORTDIR/gcc" && -L "$PORTDIR/gcc" ]];then
    rm -v $PORTDIR/gcc
fi
cp -r $URL $PORTDIR
if [[ "$?" == "0" ]];then
    echo "Success!"
else
    echo "Something failed"
fi
echo "Cleaning..."
rm -rv $URL

Now, my question is: it will be (re)supported in future ebuilds for, at least, most of the Funtoo GCC ebuilds?

Drobbins made some improvements to gcc since the 4.6.2 ebuilds, and they are not cross-compile friendly.  You have the right idea though, I've been using the Gentoo ebuilds for cross-compiling for over a year now, all works great that way, no fuss once you figure that out.  I'm a heavy distcc user with a good assortment of different machines here (including arduino).  My 1st mega on the way for this

Um, how much for the hat?

For the record, all things related to improving the state of GCC in Funtoo are being tracked on FL-1424.

Well, I understand, while Gentoo's GCC is working for toolchains, everything's ok :)
