[Q20] ``How can I compile gcc 2.7.2.1 from the gcc source code using
glibc 2.x?
[A20] {HJL} There is no support in gcc for glibc 2.0 before gcc 2.8. It
is very tricky to compile gcc 2.7.2.1 using glibc 2.x. You have to
build it manually or with one pass only. You also have to use the
specs file in this FAQ while compiling gcc.
A pre-compiled binary version of gcc 2.7.2.1 linked with glibc 2.x for
Linux/x86 is available in the same directory at the glibc 2.x source
code ftp sites.
