<p>This document outlines the steps needed to install Apache
onto an IBM TPF4.1 system. (There are separate
<a href="install-ztpf.html">installation instructions for z/TPF</a>.)
</p>
<p>You should first review <a href="readme-tpf.html">readme-tpf.html</a>
for basic information on the port of Apache to TPF including a list of
supported modules and required PUT levels.</p>
<p>The allocated <tt>CHTA</tt> program name is used throughout
these instructions to refer to Apache. You can use a different
program name if you wish.<br />
Likewise the directory structure <tt>apache/src</tt> is used
for the Apache source code directory. You can use different
directories than <tt>apache</tt> if you wish.</p>
<p>If you change the program or directory names be sure to
change the entries shown in these instructions.</p><br />
<center>
<h2><a id="download" name="download"></a>Download</h2>
</center>
<p>Releases of the Apache server are compressed into a "tarball" file
which must be downloaded to your PC. Additionally the source code from
the tarball will need to be copied onto an OS/390 UNIX System Services
machine (later referred to simply as "OS/390 UNIX") for compiling. Here
are all the details on how to get Apache and how to get it where it
needs to be:</p>
<ol>
<li><p>Download the compressed Apache 1.3 files (the "tarball") from
<a href="http://httpd.apache.org/download.cgi">http://httpd.apache.org/download.cgi</a>
to your PC. The file name on the web site will be
<tt>apache_1.3.<i>vv</i>.tar.Z</tt>, where "<tt><i>vv</i></tt>" is
the version number. Replaced "<tt><i>vv</i></tt>" throughout these
instructions with the actual version number.</p>
<p><font color="#CC6600"><font size="+1">TIP:</font></font> Be sure
to keep the <tt>.tar.Z</tt> extension when saving the file.</p>
</li>
<li>
<p>Decompress the tarball on your PC using WinZip or some other PC
decompression tool.</p>
<p><font color="#CC6600"><font size="+1">TIP:</font></font> If you
are using WinZip verify that the
<i>"TAR File Smart CR/LF Conversion"</i> option (under Options,
Configuration) is <em>not</em> checked.</p>
<p>This is what you can expect if you use WinZip:</p>
<ul>
<li>open the tarball with WinZip (this can usually be done simply
by double-clicking on the downloaded tarball)</li>
<li>you will be told that the archive contains one file
(apache_1.3.<i>vv</i>.tar) - allow WinZip to decompress it to a
temporary folder</li>
<li>extract the archived files onto your PC - you'll be using
files from the <tt>conf, htdocs,</tt> and <tt>icons</tt>
directories later in the install phase<br /><br />
</li>
</ul>
</li>
<li><p>FTP the tarball to your OS/390 UNIX machine using binary mode:
</p>
<ul>
<li>activate FTP in an MSDOS window:<br />
<b><tt> ftp <i>your.os390.unix.machine.com</i></tt></b> </li>
<li>sign in </li>
<li>set mode to binary: <b><tt>binary</tt></b> </li>
<li>send the file to OS/390 UNIX:<br />
<b><tt> send "c:/<i>path</i>/apache_1.3.<i>vv</i>.tar.Z" apache_1.3.<i>vv</i>.tar.Z</tt></b></li>
<li>exit FTP: <b><tt>bye</tt></b></li>
</ul>
<p><font color="#CC6600"><font size="+1">TIP:</font></font> UNIX file
names are case sensitive. If you use an NFS client to transfer files
from your PC to OS/390 UNIX (instead of using FTP as described above)
verify that the NFS drive will transfer the file names
with upper/lower case preserved.</p>
</li>
<li><p>On your OS/390 UNIX machine, decompress and extract the
archived files necessary for compiling Apache:</p>
<p class="indented"><b><tt>pax -rvzkf apache_1.3.<i>vv</i>.tar.Z -o from=ISO8859-1,to=IBM-1047 "*/src"</tt></b></p>
</li>
<li><p><a id="delete-expat" name="delete-expat"></a> Remove
unnecessary subdirectories:</p>
<p class="indented"><b><tt>cd apache_1.3.<em>vv</em>/src/lib<br />
rm -r expat-lite sdbm<br />
cd ../os<br />
rm -fr bs2000 cygwin mpeix netware os2 os390 unix win32<br />
cd ..</tt></b></p>
</li>
</ol>
<center>
<h2><a id="compilation" name="compilation"></a>Compilation</h2>
</center>
<p>Apache supports the notion of "optional modules". However,
the server has to know which modules are compiled into it. In
order for those modules to be effective, it is necessary to
generate a short bit of code (modules.c) which simply has a
list of them. If you are using the <tt>Configure</tt> utility
and <tt>make</tt>, modules.c and other necessary files will be
created for you automatically.</p>
<p>The provided instructions assume a c89 compiler and have
been tested on an OS/390 UNIX machine running at version 2.6
that contained both OS/390 UNIX and TPF C header files. If you
are using a platform other that OS/390 UNIX you may need to
modify src/os/tpf/TPFExport and src/Configure to match your
environment.</p>
<p><font color="#CC6600"><font size="+1">TIP:</font></font>
Editing files on your PC prior to moving them to OS/390 UNIX
may result in the loss/addition of unprintable characters.
Files of concern include shell scripts and src/Configuration.
The most common problems are with tab characters and CR/LF
characters. Most editors will handle the CR/LF problem
correctly but none seem to handle tab characters. If you need
to edit files prior to moving them to OS/390 UNIX, edit them in
a UNIX editor such as vi or emacs.</p>
<p>Note that OS/390 UNIX commands in this section are shown in
<b><tt>bold</tt></b>, are case sensitive, and must be made from
the "src" directory.</p>
<ol>
<li><p>Switch to the Apache source code subdirectory:</p>
<p class="indented"><b><tt>cd apache_1.3.<em>vv</em>/src</tt></b></p></li>
<li><p>Overlay src/Configuration with src/Configuration.tmpl:</p>
<p class="indented"><b><tt>cp Configuration.tmpl Configuration</tt></b></p></li>
<li><p>The src/Configuration file controls which optional
modules are compiled into Apache.<br />
Leave the file as-is if you want to use the default set of
modules.<br />
Otherwise edit the src/Configuration file to customize which
modules are used:</p>
<ul>
<li>Comment out (by preceding the line with a "#") lines
corresponding to those modules you do <em>not</em> wish to
include.</li>
<li>Uncomment (by removing the initial "#", if present) lines
corresponding to those modules you wish to include.<br />
(The <a href="readme-tpf.html">readme-tpf.html</a> document
lists the modules that have been tested on TPF).</li>
<li>Add lines for any custom or third party modules you wish
to include.<br />
The modules placed in the Apache distribution are the ones that
have been tested and are used regularly by various members of
the Apache development group. Additional modules contributed by
members or third parties with specific needs or functions are
available at
<a href="http://modules.apache.org/">http://modules.apache.org/</a>.
There are instructions on that page for linking these modules
into the core Apache code.</li>
<li>If you did not delete the src/lib/expat-lite directory as
noted in the <a href="#delete-expat">download instructions</a>,
add "<tt>Rule EXPAT=no</tt>" to the src/Configuration
file.</li>
<li>Adjust the other rules, <tt>EXTRA_CFLAGS</tt>,
<tt>EXTRA_LIBS</tt>, <tt>EXTRA_LDFLAGS</tt>, and
<tt>EXTRA_INCLUDES</tt> settings if you feel so inclined.<br />
</li>
</ul>
</li>
<li><p>Indicate whether the <tt>non_socket_select</tt> function is
implemented on your system.</p>
<p>If you are on a PUT12 or higher system, or have PJ26895 installed,
then you probably support <tt>non_socket_select</tt>.<br />
You can verify this by looking for the <tt>non_socket_select</tt>
prototype in your system header files (specifically
<tt>i$pwbl.h</tt>).</p>
<p>If your TPF system supports <tt>non_socket_select</tt> do
<em>one</em> of the following:</p>
<ul>
<li>add "<tt>#define TPF_HAVE_NONSOCKET_SELECT</tt>" to
<tt>src/os/tpf/os.h</tt> <em>or</em></li>
<li>add "<tt>-DTPF_HAVE_NONSOCKET_SELECT</tt>" to the
<tt>_C89_OPTIONS</tt> export in src/os/tpf/TPFExport</li>
</ul>
<p>Otherwise:</p>
<ul>
<li>add "<tt>#define TPF_NO_NONSOCKET_SELECT</tt>" to
<tt>src/os/tpf/os.h</tt> <em>or</em></li>
<li>add "<tt>-DTPF_NO_NONSOCKET_SELECT</tt>" to the
<tt>_C89_OPTIONS</tt> export in src/os/tpf/TPFExport</li>
</ul>
<p>Without <tt>non_socket_select</tt> CGI output is buffered and
only sent to the browser when the CGI program finishes.</p></li>
<li><p>Indicate whether the <tt>tpf_sawnc</tt> function is
implemented on your system.</p>
<p>If you are on a PUT10 or higher system, or have PJ27387/PJ26188
installed, then you probably support <tt>tpf_sawnc</tt>.<br />
You can verify this by looking for the <tt>tpf_sawnc</tt> prototype
in your system header files (either <tt>tpfapi.h</tt> or
<tt>i$fsdd.h</tt>).</p>
<p>If your TPF system supports <tt>tpf_sawnc</tt> do <em>one</em> of
the following:</p>
<ul>
<li>add "<tt>#define TPF_HAVE_SAWNC</tt>" to
<tt>src/os/tpf/os.h</tt> <em>or</em></li>
<li>add "<tt>-DTPF_HAVE_SAWNC</tt>" to the <tt>_C89_OPTIONS</tt>
export in src/os/tpf/TPFExport</li>
</ul>
<p>Otherwise:</p>
<ul>
<li>add "<tt>#define TPF_NO_SAWNC</tt>" to
<tt>src/os/tpf/os.h</tt> <em>or</em></li>
<li>add "<tt>-DTPF_NO_SAWNC</tt>" to the <tt>_C89_OPTIONS</tt>
export in src/os/tpf/TPFExport</li>
</ul>
<p>The use of <tt>tpf_sawnc</tt> allows for a cleaner shutdown of
Apache.</p></li>
<li><p><a id="syslog" name="syslog"></a>Indicate if you have the
Syslog Daemon message logging facility.</p>
<p>If you are on a PUT13 or higher system, or have PJ27214 installed,
you can use syslog for Apache's ErrorLog.<br />
To have the option of using syslog you must do <em>one</em> of the
following:</p>
<ul>
<li>add "<tt>#define HAVE_SYSLOG</tt>" to
<tt>src/os/tpf/os.h</tt> <em>or</em></li>
<li>add "<tt>-DHAVE_SYSLOG</tt>" to the <tt>_C89_OPTIONS</tt>
export in src/os/tpf/TPFExport</li>
</ul>
<p>You also need to add "<tt>INCLUDE OBJLIB(CSYLOG40)</tt>" to your
link JCL.</p>
<p>See the
<a href="readme-tpf.html#syslog">syslog section of readme-tpf.html</a>
for more information.</p></li>
<li><p>Indicate if you would like to use the TCP/IP network services
database. (This only applies if you are using TCP/IP native stack.)</p>
<p>If you are on a PUT16 or higher system, or have PJ28195 installed,
you can use the TCP/IP network services database. To do so, you must
do <em>one</em> of the following:</p>
<ul>
<li>add "<tt>#define TPF_HAVE_NSD</tt>" to
<tt>src/os/tpf/os.h</tt> <em>or</em></li>
<li>add "<tt>-DTPF_HAVE_NSD</tt>" to the <tt>_C89_OPTIONS</tt>
export in src/os/tpf/TPFExport</li>
</ul>
<p>See "Network Services Database Support" in the
<a href="http://www.ibm.com/tpf/pubs/tpfpubs.htm">IBM TPF Product Information Center</a>
for details.</p></li>
<li><p><a id="export" name="export"></a>Set the TPF environment
variables:</p>
<p class="indented"><b><tt>. os/tpf/TPFExport</tt></b> </p>
<p>This script will set the environment variables required to compile
the programs for TPF. Verify that the export variables are valid for
your installation, in particular, the system include file
directories. The system include files must reside on your OS/390 UNIX
system in the appropriate file structure similar to /usr/include and
/usr/include/sys. Do <em>not</em> modify the <tt>TPF=YES</tt> export
variable. If this is changed, the "Configure" script will not
recognize TPF.</p></li>
<li><p><a id="run-configure" name="run-configure"></a>Run the

<p>If you receive an error such as "<tt>Configure 146: FSUM7351 not

in the flagged file do not have trailing spaces. Using the vi editor
and the sample error above as an example...</p>

</li>
<li><p>Edit src/os/tpf/os.h if you want to use the
<tt>sigaction()</tt> function.</p>
<p>The <tt>sigaction()</tt> function supersedes the <tt>signal()</tt>
interface and should be used in preference. This function was
implemented with APAR PJ26188 which shipped with PUT10.</p>
<p>To use <tt>sigaction()</tt> remove <tt>#define
NO_USE_SIGACTION</tt> in os.h.</p>
<p>The change will only take effect after Apache is (re)compiled.</p></li>
<li><p>Edit src/os/tpf/os.h if you do <em>not</em> want the
scoreboard kept in shared memory.</p>
<p>The default behavior for Apache on all platforms <em>except</em>
TPF is to use the file system for maintaining the scoreboard (which
holds current Apache children status). The default behavior for
Apache on TPF is to use shared memory. This reduces file activity and
improves performance.</p>
<p>If you are on a pre-PUT10 system, or for some reason you do not
want to use shared memory for the scoreboard, you must remove
"<tt>#define USE_SHMGET_SCOREBOARD</tt>" from os.h</p>
<p>The change will only take effect after Apache is (re)compiled.</p></li>
<li><p>Now compile the programs:</p>
<p class="indented"><b><tt>make</tt></b></p>
<p>Besides compiling, <tt>make</tt> also runs
src/main/gen_test_char.c and src/main/gen_uri_delims.c in order to
create src/main/test_char.h and src/main/uri_delims.h respectively</p>
<p>The following compilation warning may or may not occur.
It should be ignored:</p>
<p class="indented">main/http_main.c: <tt>Infinite loop detected in function child_main. Program may not stop.</tt></p>
<p>If during compilation you get a warning about a missing 'regex.h',
set <tt>WANTHSREGEX=yes</tt> in the src/Configuration file and start
back at the <a href="#run-configure"><tt><b>Configure</b></tt></a>
step.</p>
<p>If you get a
'<tt>Duplicate type specifier "long" ignored</tt>'
error, add "<tt>-W 0,langlvl(extended)</tt>" to the
<tt>_C89_OPTIONS</tt> export in src/os/tpf/TPFExport and start back
at the <a href="#export"><tt><b>export</b></tt></a> step</p>
</li>
</ol><br />
<center>
<h2><a id="installation" name="installation"></a>Installation</h2>
</center>
<p>The allocated <tt>CHTA</tt> program name is used throughout
these instructions to refer to Apache. You can use a different
program name if you wish.</p>
<ol>
<li><p>Link the compiled object files into a DLL. Sample link JCL
has been included as src/os/tpf/samples/linkhttp.jcl. You will
need to modify this JCL:</p>
<ul>
<li>Change the IDs, data set names, and libraries for your
particular site.</li>
<li>Add/remove <tt>mod_<i>xxx</i>.o</tt> files so they correspond
to the <tt>mod_<i>xxx</i>.o</tt> lines in your src/Configuration
file.</li>
</ul>
<p><font color="#CC6600"><font size="+1">TIP:</font></font>
Do <em>not</em> include gen_test_char.o or gen_uri_delims.o in the
link JCL since these files are only used during the <tt>make</tt>
step.</p>
<p>If you receive an "Unresolved references" error for
"<tt>XML_ErrorString</tt>" you probably need to
<a href="#delete-expat">remove the expat-lite directory</a> and start
back at the
<a href="#run-configure">"Run the Configure script" step</a></p>
<p>If you receive an "unable to open" error for
<tt>lib/expat-lite/hashtable.o</tt>" you probably need to remove all
of the expat-lite .o's from your link JCL</p>
<p><font color="#CC6600"><font size="+1">TIP:</font></font>
Apache uses cinet6 from CLTY, which is part of the Internet Daemon
(zinet). Ensure that you link Apache with the proper version of CLTY
for your system. If you apply changes to CLTY you should re-link
Apache to prevent the <code>inetd_getServer</code> and/or
<code>inetd_getServerStatus</code> functions from failing.</p></li>
<li><p>Create a loadset. Sample loadset JCL has been included as
src/os/tpf/samples/loadset.jcl. You will need to modify this JCL for
your particular site.</p>
<p>A JCL condition code of 4 is expected since the C load module will
contain no link map data.</p>
<p>If you require a link map refer to the
<a href="#linkmap">instructions below</a>.</p></li>
<li><p>Load (<tt>zoldr load</tt>) and activate (<tt>zoldr act</tt>)
the loadset on your test system.</p></li>
<li><p>Ensure that the program name you are using for Apache has
<tt>RESTRICT</tt> and <tt>KEY0</tt> authorization:</p>
<p class="indented"><tt><b>zdpat chta</b> (c-c)</tt></p>
<p>If necessary you can use the <tt>zapat</tt> entry to alter the
authorization:</p>
<p class="indented"><tt><b>zapat chta restrict key0</b> (c-c)</tt></p>
<p>Note that if the program name is unallocated, you must have the
loadset for it activated or you will receive <tt>INVALID PROGRAM
NAME</tt> from the <tt>zdpat/zapat</tt> entries.</p></li>
<li><p>General documentation for Apache is located at
<a href="http://httpd.apache.org/docs/">http://httpd.apache.org/docs/</a>
and in the HTML pages included with the distribution (tarball) under
the <tt>htdocs/manual</tt> directory.</p></li>
<li><p>Create the Apache run-time configuration file. The server
requires a configuration file to initialize itself during activation.<br />
Copy the distribution version, conf/httpd.conf-dist from the
decompressed tarball on your PC, to conf/httpd.conf and then edit the
conf/httpd.conf copy with your site specific information.</p>
<p>You must change every occurrence of "<tt>@@ServerRoot@@</tt>" to
your document server root (for example "<tt>/usr/local/apache</tt>")</p>
<p>You should also add the following line to the httpd.conf file to
prevent Apache from doing a host name lookup on your test system:</p>
<p class="indented"><tt>ServerName 127.0.0.1</tt></p></li>
<li><p>On TPF activate your TCP/IP Offload (ZCLAW) or Native Stack
communications device.<br />
Refer to the
<a href="http://www.ibm.com/tpf/pubs/tpfpubs.htm">IBM TPF Product Information Center</a>
for details.</p></li>
<li><p>Using either TFTP or FTP, transfer the configuration file,
icons, and web pages to your TPF system. A typical directory
structure for Apache is as follows:</p>
<p class="indented"><tt>/usr/local/apache/conf<br />
/usr/local/apache/logs<br />
/usr/local/apache/icons<br />
/usr/local/apache/htdocs<br /></tt></p>
<p>At a minimum you will need these files on TPF:</p>
<p class="indented"><tt>/usr/local/apache/conf/httpd.conf<br />
/usr/local/apache/conf/mime.types<br />
/usr/local/apache/htdocs/index.html.en<br />
/usr/local/apache/htdocs/apache_pb.gif<br /></tt></p>
<p>All gif, jpg, and zip files should be transferred as binary; the
configuration file and html pages should be transferred as text.</p>
<p>Refer to the
<a href="http://www.ibm.com/tpf/pubs/tpfpubs.htm">IBM TPF Product Information Center</a>
for details on TFTP and FTP.</p></li>
<li><p>The logs directory must exist and be accessible in order to
avoid an <tt>fopen</tt> error while running Apache:</p>
<p>If you're running a PUT10 or higher version of TPF make the directory using a zfile commands:</p>
<p class="indented">
<b><tt>zfile mkdir /usr/local/apache/logs<br />
zfile chmod 777 /usr/local/apache/logs</tt></b></p>
<p>If you're running TPF version PUT09 TFTP an empty file into the
logs subdirectory to create it. <br />
Then make sure Apache can write into the logs subdirectory:</p>
<p class="indented"><b><tt>zfile chmod 777 /usr/local/apache/logs</tt></b></p></li>
<li><p>Add Apache to the Internet Daemon's tables using zinet
entries</p>
<p>For PUT11 and later use the "DAEMON" model for Apache:</p>
<p class="indented">
<tt><b>zinet add s-<i>apache</i> <i>pgm-chta</i> model-daemon user-root</b></tt></p>
<p>On pre-PUT11 systems use the "NOLISTEN" model instead:</p>
<p class="indented">
<tt><b>zinet add s-<i>apache</i> <i>pgm-chta</i> model-nolisten</b></tt></p>
<p><font color="#CC6600" size="4">TIP:</font> Logic changes
implemented with PUT11 cause zinet to <i>not</i> restart NOLISTEN
servers after <tt>zoldr act</tt> and <tt>zoldr deact</tt>
entries. This means that Apache running as NOLISTEN on a PUT11 or
later system will exit whenever any <tt>zoldr act</tt> or
<tt>zoldr deact</tt> entry is made. Therefore at PUT11 you
should switch to the DAEMON model and ensure that you have APARs
PJ25761 and PJ27363 applied.</p>
<p>Refer to the
<a href="http://www.ibm.com/tpf/pubs/tpfpubs.htm">IBM TPF Product Information Center</a>
for details on the Internet Daemon and zinet commands.</p></li>
<li><p>Start the server:</p>
<p class="indented"><b><tt>zinet start s-<i>apache</i></tt></b></p></li>
<li><p>Verify Apache was successfully started:</p>
<p class="indented"><b><tt>zfile cat /usr/local/apache/logs/error_log</tt></b></p>

<h2><a id="linkmap" name="linkmap"></a>Generating an Apache Link Map</h2>
</center>
<p>Three different tools can be used to generate a link map for Apache:
TPF Build Tools, TPF Toolkit, and VisualAge TPF.</p>
<h3>TPF Build Tools on OS/390 UNIX</h3>
<ol>
<li>Download and install the
<a href="http://www.ibm.com/software/htp/tpf/download/bldtools.htm">TPF Build Tools</a>
if you have not already done so.</li>
<li>Follow the instructions to set up any necessary variables for
your installation.</li>
<li>Create a shell script in your Apache <code>src</code> directory:
<table class="indented" summary="shell script">
<tr><td class="output"><pre>
ld -M --dlm -O'<your-dsd-dsn>(CHTA<vv>)' \
CSTRTD40 \
CINET640 \
buildmark.o \
modules.o \
ap/ap_base64.o \
.
.
.
regex/regexec.o \
regex/regfree.o
</pre></td></tr>
</table>In your script...
<ul>
<li>Each line must end with a backwards slash (\) except for the
last line. Be sure there are no trailing blanks after the backward
slashes.</li>
<li>Replace the two items in angle brackets (< >) with your
dataset name and program version.</li>
<li>Add any additional libraries prior to the first ".o" line.</li>
<li>Add a line for each .o to be linked into your configuration of
Apache.</li>
</ul><br />
</li>
<li>Change the shell script's permission settings to executable using
the <code>chmod</code> command.</li>
<li>Run the script.<br />
If you get a duplicate object warning for <tt>@@DLMHDR</tt> remove
the <tt>CSTRTD40</tt> line from the script and re-run.<br />
(You'll see this warning if the ld processing is automatically
including <tt>CSTRTD</tt>.)</li>
</ol>
<h3>TPF Toolkit</h3>
<ol>
<li>Copy the sample <tt>linkhttp.dlm</tt> file from the
<tt>src/os/tpf/samples</tt> directory to your Apache <tt>src</tt>
directory on OS/390 UNIX.</li>
<li>This sample file contains the components for the default
configuration of Apache. Add and delete components (such as modules)
as necessary so it matches your configuration of Apache. Basically,
it should match your link JCL with the "<tt>.../apache/src</tt>"
portion of the filenames removed.</li>
<li>Change items in angle brackets (< >) to also match your
JCL. Be sure to remove the angle brackets as well.</li>
<li>In the TPF Toolkit create a project with your modified dlm file
as its sole contents.</li>
<li>Right click on the dlm file in your new project and choose "Build
DLM".</li>
</ol>
<h3>VisualAge TPF</h3>
<ol>
<li>Copy the sample <tt>linkhttp.dlm</tt> file from the
<tt>src/os/tpf/samples</tt> directory to your Apache
<tt>src</tt> directory on OS/390 UNIX.</li>
<li>This sample file contains the components for the default
configuration of Apache. Add and delete components (such as modules)
as necessary so it matches your configuration of Apache. Basically,
it should match your link JCL with the "<tt>.../apache/src</tt>"
portion of the filenames removed.</li>
<li>Change items in angle brackets (< >) to also match your
JCL. Be sure to remove the angle brackets as well.</li>
<li>In VisualAge TPF create a container with your modified dlm file
as its sole contents.</li>
<li>Right click on the dlm file in your new container and choose
"Build DLM".</li>
