Hi Robin,

Thank you for the suggestion. Yes, I had to install the package gcc-multilib as part of the build process. 

My issue is now solved. I first used the script "fix_x86_64-unknown-linux-gnu", and then had to install a few other packages (such as automake, gcc-multilib, autoconf, gnome-core-devel, etc.) to resolve dependencies.

Regards,
Swarnendu Biswas.

Hi Swarnendu,

Do you have the package gcc-multilib installed ?
