I was trying to install compat-gcc-34-3.4.6-7.src.rpm on Fedora core7 i386. Following command and error occur. I have change the yum entry by adding baseurl=file:///media in all yum files of yumrepos.d. Pleace tell me how to solve it little urgent.

Well,
Not sure what you did to your repository entries, but if you go here and copy and past the missing dependencies in the search field, click "search" and find your distribution and download the file and install it with rpm install command, for example:
Copy and paste "libc.so.6", on the fourth page, the package for Fedora 7 64bit is 'glibc-2.6-3.x86_64.rpm'
Copy and paste "dejagnu", on the first page, the package for Fedora 7 64bit is 'dejagnu-1.4.4-7.noarch.rpm'
Copy and paste "libc.so" on the sixth page, the package for Fedora 7 64bit is 'glibc-devel-2.6-4.x86_64.rpm'
Copy and paste "elfutils-devel", on the second page, the package for Fedora 7 64bit is 'elfutils-devel-0.129-1.fc7.x86_64.rpm'

Chances are, if you would have left your repositories the way they were, these packages would have been automatically installed instead of getting the errors.
Install with command:
You say you have Fedora 7 i386 which is 32bit, why do the errors look in /usr/lib64 & /lib64?, there should be no such thing (64) in a 32bit system.

BTW:
Why are you trying to install the source rpm?
Take a look at this exellent guide to see how to install compat-gcc-34.

Thanks "Junior Hacker"
The Problem is solved.
Sorry I did not answer earlier because I was too busy in my project work.I Solve the problem by copying gcc file FC-3 CD disk.
I donot know why my Laptop giving /lib64 error. Does it is due to installing i386 on dual core.

It should not make a difference, the Dual core is strictly 32bit (i386), the Core 2 Duo is multi-architecture, which means you can install either 32bit (i386) or 64bit (x86_64). And the package was not architecture specific according to it's name as it is a source rpm.
What's strange is that the output suggests installing "---> Package compat-gcc-34.ppc" which is for Apple computers with the IBM processor, not an Intel processor like the Dual Core and Core 2 Duo and Pentium line. Plus it has those references to 64bit libraries in the output also. So something is really funny in the output of that Yum Install Process.
By typing uname -ra in a terminal you should get something similar to the one quoted below from my fresh installation of F7 i386, which shows "i386" towards the end instead of "x86_64" which would be 64bit:
I don't have any "lib64" directories in my i386 installation.

As per instructions in the Personal Fedora 7 installation link I provided, all you needed to do to install Compat gcc-34 was issue command:
To install compatible gcc-2 and gcc-3 libraries:
These two commands should install packages designed for Fedora 7.
