@bluehole
thank you for reply!!!
I will explain my requirement in detail...
The host machine has centOS 5.0 linux installed. And the target device is AT91SAM9M10G45EK arm processor.
Now, I have the source code of bootstrap, uboot, kernel and rfs of the embedded linux which I have to install on the target device. But, for installation I must compile the source code and get the binary file of it.
If I compile the source code on the host linux machine, it will be compiled for 32 bit processor(i.e. the host processor)
So, in order to compile the source code for the target device, I must have the cross compiler installed on the host machine which will compile the source code on the host machine for the target device.
Please let me know the name of cross compiler, toolchain for the same purpose.
