Compiling glibc from source with debug symbols

Question

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?

Answer 1

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

How do i later make a sample code link to this particular glibc rather than the one installed on my system?

This is somewhat tricky, and answered here.
