You +do not need to use the development kernel, just have its headers where +glibc can get at them. The easiest way to do this is to unpack a +development kernel in a directory such as `/usr/src/linux-dev'. In that +directory, run `make config' and accept all the defaults. Then +configure glibc with the option +`--with-headers=/usr/src/linux-dev/include'. Use the latest +development kernel you can get your hands on. + + An alternate tactic is to unpack the development kernel and run +`make config' as above. Then rename or delete `/usr/include', create a +new `/usr/include', and make the usual symbolic links of +`/usr/include/linux' and `/usr/include/asm' into the development kernel +sources. You can then configure glibc with no special options. This +tactic is recommended if you are upgrading from libc5, since you need +to get rid of the old header files anyway. + + Note that `/usr/include/net' and `/usr/include/scsi' should *not* be +symlinks into the kernel sources. GNU libc provides its own versions +of these files. + + Linux expects some components of the libc installation to be in +`/lib' and some in `/usr/lib'. This is handled automatically if you +configure glibc with `--prefix=/usr'. If you set some other prefix or +allow it to default to `/usr/local', then all the components are +installed there. + + If you are upgrading from libc5, you need to recompile every shared +library on your system against the new library for the sake of new code, +but keep the old libraries around for old binaries to use.
