How to Install a Cross-Compiler Toolchain (Successfully Compiled)

First, copy the file arm-linux-gcc-4.3.2.tgz from the CD directory linux\ to a local directory such as tmp\, then

navigate into that directory and execute the extraction command:
#cd /tmp
#tar xvzf arm-linux-gcc-4.3.2.tgz –C /
Note: There is a space after –C, and C must be uppercase. It stands for the word "Change", meaning to change the target directory.
Executing this command will install arm-linux-gcc into the /usr/local/arm/4.3.2 directory.

Second, add the compiler path to the system environment variables by running:
#gedit /root/.bashrc
Edit the /root/.bashrc file, and add the following line at the end:
export PATH=$PATH:/usr/local/arm/4.3.2/bin
Save the file and exit, as shown in the figure.

Third, log back into the system (no need to reboot—just log out via Start -> Logout) to activate the above settings. Then type the following command in the terminal:
arm-linux-gcc –v
If you see output similar to the one shown below, the cross-compilation environment has been successfully installed.

The key point in the above installation process is identifying the directory where the arm-linux-gcc executable resides after extracting the package (you must manually verify its presence—otherwise, you'll waste time guessing).

Once you locate the command, use the pwd command to display the current path, then copy this path into the /root/.bashrc file.
