Question on compiling glibc

[Tim Rühsen]

Hi Jason,

I am also new to glibc and didn't have much time for it yet.

You should read or search
[1] https://sourceware.org/glibc/wiki/Testing/Builds
[2] https://sourceware.org/glibc/wiki/FAQ
[3] https://sourceware.org/glibc/wiki/HomePage

Especially [1] helped me to build&run test code with a home-made glibc.

Regards, Tim
