Hi Anil!

I've finished compiling mspgcc4 under Ubuntu 11.04 x86, and it works well! :)

I followed these instructions http://rubenlaguna.com/wp/2011/02/11/compiling-openchronos-in-windows/ with few modifications to Ubuntu.

Modded steps for Ubuntu:

First step: You will need to install these packages wget, patch, make, python, perl(these are installed in basic install of Ubuntu), and install texinfo, gcc-4.4, g++-4.4, and git.

...follow Rubén's 2.-3. step...

Fourth step: Before you start to build mspgcc4, you have to edit the buildgcc.pl(or use the version I've sent with this mail). In line 137 there is $GNU_MIRROR="http://ftp.uni-kl.de";
you should change it to $GNU_MIRROR=http://mirrors.usc.edu; because the ftp.uni-kl.de gives 404 to the binutils 2.21 sourcefile.
Change the URL at line 15 in do-binutils.sh . Now you can follow Rubén's fourth step.(Rubén's selections [gcc-4.4.5, no gdb, no insight, ti_20110130, and the rest of the defaults] worked for me here)(It takes 2,5 hours)

...follow Rubén's 5. step...

Sixth step: Add export PATH=$PATH:/opt/msp430-gcc-4.4.5/bin to /etc/bash.bashrc

After that, you can follow Rubén's steps until your first finished firmware! :)
