| 17 | If the base system is running a 2.0 kernel and the Glibc version is
|
|---|
| 18 | 2.1 then a user 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 he has problems executing the
|
|---|
| 21 | m4 program in the chroot'ed environment (for example when he installs
|
|---|
| 22 | the autoconf and automake packages) he'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 he runs kernel 2.0, 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 any problems.

| 47 | this can be done
|
|---|
| 48 | after having rebooted into the LFS system rather than chrooting into it.
