I need to compile glibc from source with debug symbols .
1.Where do i specify the '-g' option for this
2.How do i later make a sample code link to this particular glibc rather than the one installed on my system?

You will have hard time compiling glibc without debug symbols. A default ./configure && make will have -g on compile line.

This is somewhat tricky, and answered here.
回答2:
It is probably a matter of configure tricks. First, try configure --help and then, either configure --enable-debug or perhaps configure CC='gcc -g' or even configure CFLAGS='-g'
For your sample code, perhaps consider playing LD_LIBRARY_PATH or LD_PRELOAD tricks (assuming linking to dynamic library).
But be very careful, since the Glibc is the cornerstone of Gnu/Linux like systems.
