I'm not sure why this would not happen for you. [Prashant] Actually after looking at the config status, I found gcc was looking for x86_64-unknown-linux-gnu prefix [Prashant] before all binutils utilities, but I did not configured binutils with --program-prefix. After doing that while configuring binutils, it seems to proceed and use the custom linker. And I see that the built is successful. So, now I can take my built tree completely and relocate to all the machines. Is there a way to check this by seeing "--print-search-dirs" or some other option with gcc/g++, before actually relocating the tool-chains. >>[Prashant] After copying the tool-chain onto a different machine, I am seeing the gcc/g++ still looks for the complete sysroot path, which is not present on this machine, so I am not able to use the tool chain. How is it possible ? Thanks Ian
