Linux Host Installation

The GNU software development tools were tested on a Celeron computer running Linux Fedora Core 5.

Tip

The GNU software tools for Linux that are set up in this procedure enable you to build the examples for all chapters except Chapter 12. The examples in Chapter 12 are intended to run on the Arcom board’s embedded Linux operating system. The GNU tools installation for building the Chapter 12 example code is covered in Appendix E.

GNU Software Tools Installation

The GNU software tools are installed under the /opt directory. To install them and make them usable, follow these steps. (You will need to ensure that you have permission to become superuser (root) in order to perform the Linux setup successfully).

  1. Open a terminal window and change to the /opt directory with the command:

  3. The Linux version of the ARM-based GNU tools is located in the file linuxhost.tar.gz. Copy this file to the /opt directory. Next, decompress the file on your hard drive using the command:

  4. # tar xvzf linuxhost.tar.gz
  5. Finally, set the path to the GNU tools location in your bash shell profile. This ensures the path is set correctly each time the bash shell is started. Edit the bash profile file named $HOME/.bash_profile (where $HOME is specific to your environment). Add the following to the last line in this file:

  6.                      PATH=/opt/gnutools/arm-elf/bin:$PATH ; export PATH

You should notice that the GNU development tools are installed under /opt/gnutools. The executable files, such as arm-elf-gcc ...
