Hi, I am newbie of linux and I got some stupid questions when I am trying to install OR1Ksim, GNU Toolchain and ORPSOC into linux(Ubuntu12.04).

I start to install GNU Toolchain first:
1)Downloaded "OpenRISC newlib toolchain 1.0rc1 compiled under Ubuntu x86/i686 (32-bit)" into direction /home/dan
2)sudo -i
3)cd /opt
4)tar xjf path to or32-elf-1.0rc1-x86.tar.bz2
5)sudo ln -s or32-elf-1.0rc1 or32-elf
6)sudo ln -s or1ksim-0.5.1rc1 or1ksim
7)~/.bashrc
8)export PATH=$PATH:/opt/or32-elf/bin:/opt/or1ksim/bin

At step(4), it said
tar(child):path:cannot open:No such file or directory
tar (child): Error is not recoverable: exiting now
tar:Child returned status 2
tar:Error is not recoverable: exiting now
Is it because or32-elf-1.0rc1-x86.tar.bz2 is not in the /opt? How to download it using svn co? I have tried svn co ftp://ocuser:ocuser@openrisc.opencores.org/toolchain/or32-elf-1.0rc1-x86.tar.bz2 but it doesnt work.

In step(7), it said Permission denied. But I think I have entered the admin account by typing sudo -i and the terminal becomes root@ubuntu:. Why will this happen?

Thank you for the help and sorry about those stupid questions
Dan

Hi Dan,

Problem with step 4 is that you have literally typed the words "path to or32-elf-1.0rc1-x86.tar.bz2". The "tar" command therefore thinks you are asking it to open an archive in a file called "path".

What the instructions mean is that you should substitute the actual file path to where the downloaded file is. In your case you say you downloaded into /home/dan, so you want

tar xjf /home/dan/or32-elf-1.0rc1-x86.tar.bz2

I don't know why you are trying to do step 7. ".bashrc" is a file in your home directory (i.e. /home/dan, shortened to "~") which is sourced (not executed) each time you start a new bash shell. What I believe you should be doing is editing that file, to add at the end the line:

export PATH=$PATH:/opt/or32-elf/bin:/opt/or1ksim/bin

The environment variable "PATH" is a ":" separated list of all the directories where the shell looks for programs. You are just adding the location of the tool chain and or1ksim binaries to the end of that list. Once you have done this any new shell will automatically find commands like or32-elf-gcc. If you want to automatically find commands in the existing shell, then use the command:

source ~/.bashrc

One other practical tip. It's generally a good idea to do as little programming as possible as root (i.e. after running "sudo -i"). It is quite common to make /opt writable by all users, so anyone can install programs there without needing to be root. You can do this with the command:

sudo chmod ugo+rwx /opt

and entering your password to enable the sudo. Then you'll be able to carry out all the above steps without needing to use "sudo -i".

If you need more help, post here, or for a quicker (probably) response, use IRC on freenode.net, channels #opencores and #openrisc.

HTH
