[shariefbe]

Hello,
I am trying to install ARM tollchain in my GCC. But i am not getting to install correctly. When i try to compile an u boot image i am getting the following errors in last few lines ..

what will be the error. can anyone tell me. i think the path exported is wrong. please help me

[shariefbe]

I think there might be a PATH error
i installed my compiler in /home/CodeSourcery/Sourcery_G++_Lite/bin

So shall i export the path as

export PATH=$PATH:/home//CodeSourcery/Sourcery_G++_Lite/bin
or

export ARM_TOOLCHAIN=/home/ariem/CodeSourcery/Sourcery_G++_Lite/bin/
is it right? which is correct one?

Then what will come for


export CROSS_COMPILE=
why it is needed?

The red text indicates you dont have a permission. You need to use sudo command to grant you superuser priviliges.

I ve managed to set up ARM toolchain (Sourcery G++ Lite allso), but i have a problem compiling source files for ARM9.

First of all check what locations are currently stored in ur PATH enviroment variable. Use command

printenv
to check that. You will see that PATH aint empty. There are numerous locations stored there and are sepparated by ":".

Make sure that when you use command

PATH=/home/codesourcery/lib:"${PATH}" you specify blue and red code. You can read this command just like any program command. First you say that variable (PATH) is (=) path you want to add (/home/codesourcery/lib) then you add blue code to separate this path from other paths and
then you specify variable (PATH) values that are currently saved there.

To make sure you added new directory sucessfully again use setenv command and look if your directory is one of the directories in PATH variable. If it is so then use
comand

export PATH

Hope it helps.
