for texinfo to be compiled properly). Added --with-curses to bash's configure again like previously done. This now functions as a test to make sure the libraries are setup properly (ie; that symlink created and such) git-svn-id: http://svn.linuxfromscratch.org/LFS/trunk/BOOK@1181 4aa44e1e-78dd-0310-a6d2-fbcd4c07a689

|
<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 the user chroot'ed into $LFS or when he rebooted
|
|
the system into LFS.</para>
|
|
|
|
<para><userinput>--bindir=$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: the /usr partition might be on a separate
|
|
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>--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>It is not strictly necessary for the static bash to be linked
|
|
against libncurses (it can link against a static termap for the time
|
|
being just fine because we will reinstall Bash in chapter 6 anyways,
|
|
where we will use libncurses), but it's a good test to make sure that
|
|
the ncurses package has been installed properly. If not, you will get in
|
|
trouble later on in this chapter when you install the Texinfo package.
|
|
That package requires ncurses and termcap can't reliably be used
|
|
there.</para>
|
|
|
|
<para><userinput>ln -sf bash sh:</userinput> This command creates the sh
|
|
symlink that points to bash. Most scripts run themselves via 'sh'
|
|
(invoked by the #!/bin/sh as the first line in the scripts) which
|
|
invokes a special bash mode. Bash will then behave (as closely as
|
|
possible) as the original Bourne shell.</para>
|
|
|
|
<para>The <userinput>&&</userinput>'s at the end of every line cause
|
|
the next command to be executed only if the previous command exists
|
|
with a return value of 0 indicating success. In case all of these
|
|
commands are copy&pasted
|
|
on the shell, is is important 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.</para>
