What should i do?mail me at tanmoy.justu@gmail.com

Have you checked your build environment to see that you satisfy dependencies?

Try this
 

Your problem is with building, not installing. There are other problems with actually installing that I don't know how to solve yet. But you may be able to get a good build by adding CFLAGS=" -march=i386 -O2" to your configure command---or whatever architecture you have in the -march= specification. I think this has been required since glibc version 2.6. Omitting the architecture produces errors like those you posted, though I don't know for sure if this will solve your build problem

Good call, Garlictoast. However, glibc2.7 or later won't build with -march=i386, but setting -march=i486 or higher will allow the build to proceed. For my environment, I did the following:
