Installing and Uninstalling the Komodo Tool under Linux

This document shows you how to install and uninstall the precompiled Komodo Tool for the DSLMU microcontroller Board under the Linux operating system.

In this document, “$” will indicate the ordinary user’s shell prompt, and “#” will indicate the root superuser’s shell prompt. Anything in a bold monospaced font is what you are expected to type in; an ordinary monospaced font is used for the computer’s response. Please note that this document doesn’t always show every response from the computer!

Minimum System Requirements

The board/software/linux The precompiled binaries of the Komodo debugger for the Linux operating system have been compiled with GNU C compiler version 3.2.2, GNU C library version 2.3.2, GTK library version 1.2.10, and XFree version 4.3.0, on Red Hat Linux operationg system version 9.0, with kernel version 2.4.20-28.8.

In order to successfully install and run the Komodo Tool, you will need to meet at least the following requirements:

1. A relatively modern Linux system with kernel version 2.0 or later, with the GNU C library version 2.2.3 or later, GTK wrapper for low-level windowing library version 0.8.0 or later GTK advanced widget set library version 1.28 or later, and with XFree 3.3 or later as the graphical interface.
Any modern Linux distribution (anything later than about 2000), such as Debian GNU/Linux 3.0 or Red Hat Linux 7.2, will satisfy these requirements. Of course, later versions will, as well… If you wish to be certain, however, you can check for yourself:
a) You can determine the operating system version by running uname -r. Anything later than version 2.0 is OK (eg, 2.2.19 or 2.4.17). For those technically inclined, the only requirement that the Linux kernel must satisfy is the ability to run ELF binaries.
b) All modern Linux systems will most definitely be running version 2 of the GNU C Library. If you need to be certain, you can check by typing ls -l /lib/libc.so.6; this should be a symbolic link to libc.version.so, where version is the version number; this should be 2.x.y for some values of x and y. The complete version number needs to be 2.2.3 or later. If you get the error message “No such file or directory”, or if your library version number is less than 2.2.3, you will need to install the Komodo Tool from source.
c) You can check the version of GTK library by typing gtk-config --version. This should be 1.2.x for some value of x, or 2.x.y for some values of x and y. Please note that you may need to run this command as the root superuser, depending on your system.
d) You can check the version of XFree86 that you are running by typing XFree86 -version. This should be 3.3.x for some value of x, or 4.x.y for some values of x and y. Please note that you may need to run this command as the root superuser, depending on your system.
2. At least 10 MB of free disk space.
The df command will give you this information. If your system is correctly set up, man df will give you some documentation on how to run this command and how to interpret its results. Remember that the man (manual page) command is your friend!
3. The password for the root superuser’s account on your system.

Installation Instructions

Installing the Komodo Tool is quite simple, but be careful that you type in the commands exactly as shown! These instructions assume that you have already mounted the CD-ROM on your computer, and that the mount point (where the CD-ROM can be found within the file system) is /mnt/cdrom. See the instructions for mounting the CD-ROM for more details.

1. Log in as an ordinary user, not as the root superuser. This is highly recommended and is standard Unix practice. In fact, you should never directly log in as the root superuser; this helps save you from your own mistakes and/or any viruses that can destroy the working of your system!
2. Check that your path contains /usr/local/bin:
$ echo $PATH
/usr/local/bin:/bin:/usr/bin:/usr/bin/X11
The response on your system might be different — that is OK as long as it contains /usr/local/bin. If it does not, you will need to read your system manuals to determine which file you need to modify (usually /etc/profile) and how to do so.
3. Become the root superuser (you will need the superuser’s password here) and change to the root directory:
$ /bin/su
# cd /
4. Unpack the Komodo Tool archive:
# tar xzvf /mnt/cdrom/board/software/linux/komodo-linux-i386-2006-02.tar.gz
By the way, the cautious (ie, good) system administrator will check the contents of this archive before installing it! To do this, use tzvf instead of xzvf in the above command.
5. Exit the root superuser’s shell:
# exit
6. You have successfully installed the Komodo Tool under Linux!

Uninstallation Instructions

Removing the precompiled Komodo Tool from your system is as easy as installing them. These instructions assume that you have the CD-ROM mounted on /mnt/cdrom before you begin.

1. Log in as an ordinary user, not as the root superuser. Once again, this is highly recommended for security reasons.
2. Become the root superuser and change to the root directory:
$ /bin/su
# cd /
3. Execute the uninstall script:
# /mnt/cdrom/board/software/linux/komodo-linux-i386-2006-02.uninstall
By the way, any system administrator worth his or her salt will check the contents of this uninstall script before running it! You wouldn’t open an executable attachment sent to you in an e-mail, now, would you?
4. Exit the root superuser’s shell:
# exit
5. You have successfully uninstalled the Komodo Tool from your system.

Common Problems

In most cases, you will not encounter any problems in installing the Komodo Tool. There might be exceptions, however. You should check the following if any step terminates with an error:

• Check that you entered all commands exactly as specified. Please note that your browser may split up commands over a number of lines (depending on the width of your browser window); that does not mean you do the same! Each shell prompt (“$” or “#”) indicates a single command line.

If your efforts at installing the Komodo Tool fail, please consult your lecturer or another suitably competent person. Good luck!
