gcc and glibc

gcc and glibc

[Bill Cunningham]

    I want to compile a new gcc and glibc. Glibc and how to switch it over 
to be the main library is complicated enough to me and OT so I will not 
mention that.

    As far as gcc goes  I want to upgrade from the 3.x.x series to 4.6.0. 
How can I create a working compile that uses the least amount of glibc as 
possible. Maybe it is a cross compiler I am looking for. I want to upgrade 
my whole system. The reason I am not just getting a newer version of linux 
is that the newer flavors are not to my liking. Any suggestions?

You should be able to compile your new version of gcc using the existing gcc  
that you have installed.

P.S. There's nothing wrong with trying to rebuild your own system all by  
yourself. It's a good learning experience. But it won't be easy. That's why  
distributions exist.

I suppose one way you could build a gcc that uses very little from glibc
would be to first build a cross-compiler which uses newlib, and then use
that cross-compiler to build gcc.  I'm sure you would run into a number
of hurdles, but I expect they could be overcome with effort.
