Install Cross compile tools 4.4.3

To compile kernels, Qtopia, bootloader and other programs in Linux you need a cross compile environment. We used arm-linux-gcc-4.5.1, The following steps will introducehow to build a compile environment. 

Step 1: copy the compressed file “arm-linux-gcc-4.4.3.tgz” in the shipped CD into a system’s directory, e.g “tmp\”, enter this directory and execute the following commands: 

#cd \tmp 
#tar xvzf arm-linux-gcc-4.4.3.tgz   –C /   

there is a space after “C” and “C” is a capital letter. 

These commands will install "arm-linux-gcc" in  the "/opt/FriendlyARM/toolschain/4.4.3" 

Step 2: run the command below to add the compiler’s path to system variables: 

#gedit /root/.bashrc 

This is to edit the “/root/.bashrc” file. Update the last line with “export PATH=$PATH:/opt/FriendlyARM/toolschain/4.4.3/bin” in the opened file, save and exit the file. 

Logout and login the system again (no need to reboot the system, just go to “start”-> “logout”)  the  above  settings  will  take  into  effect.  Type  “arm-linux-gcc –v”,  if  the messages depicted in the screen shot below appear it indicates the compile environment has been set up successfully.
