<para>
|
|
<userinput>--enable-static-link:</userinput> This configure
|
|
option causes Bash to be linked statically
|
|
</para>
|
|
|
|
<para>
|
|
<userinput>--prefix=$LFS/usr:</userinput> This configure option installs
|
|
all of Bash's files under the $LFS/usr directory, which becomes the /usr
|
|
directory after you chroot into $LFS or when you reboot the system into LFS.
|
|
</para>
|
|
|
|
<para>
|
|
<userinput>--bindir=$LFS/bin:</userinput> This installs the executable
|
|
files in $LFS/bin. We do this because we want bash to be in /bin, not in
|
|
/usr/bin. One reason being: your /usr partition might be on a seperate
|
|
partition which has to be mounted at some point. Before that partition is
|
|
mounted you need and will want to have bash available (it will be hard to
|
|
execute the boot scripts without a shell for instance).
|
|
</para>
|
|
|
|
<para>
|
|
<userinput>--disable-nls:</userinput> This disables the build of NLS
|
|
(National Language Support). It's only a waste of time for now as Bash
|
|
will be reinstalled in the next chapter.
|
|
</para>
|
|
|
|
<para>
|
|
<userinput>--with-curses:</userinput> This causes Bash to be linked
|
|
against the curses library instead of the default termcap library which
|
|
is becoming obsolete.
|
|
</para>
|
|
|
|
<para>
|
|
<userinput>ln -s bash sh:</userinput> This command creates the sh
|
|
symlink that points to bash. Most scripts run themselves via 'sh'; sh
|
|
being a symlink to the default system shell. Because programs and
|
|
scripts don't know what shell you use by default (could be bash, ksh,
|
|
korn, tch, csh and others) they use the common symlink sh which, if the
|
|
system is properly setup, always points to the system's default shell.
|
|
</para>
|
|
|
|
<para>
|
|
The <userinput>&&</userinput>'s at the end of every line cause
|
|
the next command only to be executed when the previous command exists
|
|
with a return value of 0 indicating success. In case you copy&paste
|
|
all of these commands on the shell you want to be ensured that if
|
|
./configure fails, make isn't being executed and likewise if make fails
|
|
that make install isn't being executed, and so forth.
