BinaryToolchain

Attached are binary of the tools to run on Linux PC and root fs from buildroot. You can use it to compile kernel and apps.

Login as a user account on Linux PC, eg, hippo. The user home dir will be /home/hippo, short form as ~/ .

Use wget to download the cross tools (69MB). Best thanks to Altera's kindly hosting these files. (but don't use Windows ftp, it corrupt the files)

wget http://www.niosftp.com/pub/gnutools/...080203.tar.bz2

sha1sum nios2gcc-20080203.tar.bz2

6873249d8eae7c2981aac6791f044ddaab507566  nios2gcc-20080203.tar.bz2

Open a terminal. Run as root or use sudo,
sudo tar jxf nios2gcc-20080203.tar.bz2 -C /

The cross gcc tools was expected to be installed in /opt/nios2 dir. But you may install in any other dirs. Then setup the PATH for the cross gcc, you can add a line at the end of file ~/.bash_profile (or ~/.profile on Debian/Ubuntu) ( the file is hidden, you have to use "ls -a" to find it . For "gedit" use open Location, and enter the file name)

Check with,
echo $PATH
It should display like this, with nios2 path at the end,
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/nios2/bin

To verify the cross gcc, try out,
nios2-linux-uclibc-gcc -v
It should display the info,
Reading specs from /opt/nios2/lib/gcc/nios2-linux-uclibc/3.4.6/specs
Configured with: /root/buildroot/toolchain_build_nios2/gcc-3.4.6/configure --prefix=/opt/nios2 --build=i386-pc-linux-gnu --host=i386-pc-linux-gnu --target=nios2-linux-uclibc --enable-languages=c --enable-shared --disable-__cxa_atexit --enable-target-optspace --with-gnu-ld --disable-nls --enable-threads --disable-multilib --enable-cxx-flags=-static

Then try build kernel and apps as in the uClinuxDist.
