I have tried using buildroot, but I didn't see an option to compile gcc/g++. Also, whenever I try to make it, it fails with: "/bin/sed: no input files" I am building it on Debian in a virtualbox on Mac OS X Mavericks. I also tried it on an iMac G3 running Debian powerpc, but that failed too, with this error message: "*** glibc detected *** genext2fs: free(): invalid next size (fast): 0x105d4998 ***

" It looks like it compiled the rootfs properly, but it couldn't make the image, it also fails if I tell it to make an ext4 image instead of ext2.

EDIT: I just tried rebuilding it without the ext2 filesystem, and it worked! but I still don't see gcc/g++ in the target packages... should I select binutils?

gcc/g++ still aren't there after I press 'z'. Also, whenever I startx the calc freezes

I don't know how the option is called, but you can always show all options in the config tool if you press 'z' and then '?' on the appropriate item to find out why it is disabled.

You have to enable "deprecated packages" or something like that. Anyway, gcc/g++ are really slow on the nspire, so there's not much of a point in using them.

Either something is broken in your buildroot or with the kernel.. What does /var/log/Xorg.0.log say?

Somewhere there is one - maybe stdout of the Xserver?

Which buildroot config do you use? This is the one use for the xconfig image.

Weird, I know that the latest "extended" kernel works fine together with the latest xconfig.
