Before starting to build TeX Live, set up your PATH so
|
|
that the system can properly find the files. If you set up your login
|
|
scripts as recommended in <xref linkend='postlfs-config-profile'/>, update
|
|
the needed paths by creating the
|
|
<filename>texlive.sh</filename> script. The programs are always
|
|
installed in an <ARCH>-linux subdirectory and on 32-bit x86 this is
|
|
always i386-linux. For x86_64 and i?86 we can generate this as $TEXARCH:

<para>
|
|
If upgrading from a previous year's version, you should manually
|
|
edit <filename>texlive.sh</filename> to ensure that the version for
|
|
the year you wish to use is the only TeX present (some people need to
|
|
keep multiple years available to ensure there are no regressions in
|
|
their documents).

<!-- EOF should NOT be in double quotes, we want it to evaluate $TEXARCH -->

<para>Now, create the texlive.sh script as the &root; user:</para>

<para>

The standard MANPATH and INFOPATH path are specified above to
|
|
ensure they are included. If they are already set in the boot script
|
|
procedure, the pathappend function will ensure duplicates are
|
|
removed, so including them here will do no harm.

The backslashes before the dollar signs in the script above are to

facilitate a copy/paste operation. The backslashes should not

appear in the actual script.

The new paths can be immediately activated by running <command>source

You should now proceed either to <xref linkend="tl-installer"/> for

a binary installation of texlive, or to <xref linkend="texlive"/> to begin

installing from source.
