| 17 | If you're base system is running a 2.0 kernel and your Glibc version is
|
|---|
| 18 | 2.1 then you will most likely get problems executing M4 in the
|
|---|
| 19 | chroot'ed environment due to incompatibilities between the M4 program,
|
|---|
| 20 | Glibc-2.1 and the running 2.0 kernel. If you have problems executing the
|
|---|
| 21 | m4 program in the chroot'ed environment (for example when you install
|
|---|
| 22 | the autoconf and automake packages) you'll have to exit the chroot'ed
|
|---|
| 23 | environment and compile M4 statically. This way the binary is linked
|
|---|
| 24 | against Glibc 2.0 (if you run kernel 2.0 you're Glibc version is 2.0 as
|
|---|
| 25 | well on a decent system. Kernel 2.0 and Glibc-2.1 don't mix very well)
|
|---|
| 26 | and won't give you any problems.

| 45 | Now you can re-enter the chroot'ed environment and continue with the
|

| 46 | next package. If you wish to recompile M4 dynamically, you can do that
|
|---|
| 47 | after you have rebooted into the LFS system rather than chroot'ed into it.
