====== Check out, build & install paclink-unix ======
  * [[https://groups.yahoo.com/neo/groups/paclink-unix/conversations/topics/331 | setup for getting paclink-unix working on Ubuntu]] - from paclink-unix forum on Yahoo.
    * These instructions are old & use the un-maintained code from SourceForge. Keep reading to see how to get the latest code from the github repository.
===== Get current source code for paclink-unix =====
  * To get a copy of the current repository use [[https://github.com/nwdigitalradio/paclink-unix | this link]]:

<code>
git clone https://github.com/nwdigitalradio/paclink-unix
</code>

  * Old notes for reference only from [[plu:install_plu:oldnotes | deprecated SourceForge repo]]
===== Satisfy all paclink-unix build requirements =====

  * Install required build tools
<code bash>
sudo apt-get install build-essential autoconf automake libtool
</code>
 
  * During the installs shown below if any prompts come up just choose default
    * postfix will prompt for the type of installation you want but for this case the config files are manually edited so your choice is not critical.

==== On Debian (6.x) Squeeze ====

  * Required packages for Debian Squeeze
<code bash>
sudo apt-get install postfix libdb-dev libglib2.0-0 zlib1g-dev libncurses5-dev libdb4.8-dev libgmime-2.4-dev
</code>

==== On Debian (7.x) Wheezy ====

  * Required packages for Debian Squeeze
<code bash>
sudo apt-get install postfix libdb-dev libglib2.0-0 zlib1g-dev libncurses5-dev libdb5.1-dev libgmime-2.6-dev 
</code>

===== On Raspian Wheezy ====
  * Note that the RPi Raspian install is identical to Debian Wheezy
 <code bash>
sudo apt-get install postfix libdb-dev libglib2.0-0 zlib1g-dev libncurses5-dev libdb5.1-dev libgmime-2.6-dev
</code>

===== On Raspian Jessie, Stretch or Buster ====
  * Note that the RPi Raspian install is identical to Debian Jessie
 <code bash>
sudo apt-get install postfix libdb-dev libglib2.0-0 zlib1g-dev libncurses5-dev libdb5.3-dev libgmime-2.6-dev
</code>

===== On Debian bullseye ====

  * Even though libgmime 3.0 is available, use the older libgmime 2.6 until port to 3.0 is complete.
 <code bash>
sudo apt-get install postfix libdb-dev libglib2.0-0 zlib1g-dev libncurses5-dev libdb5.3-dev libgmime-2.6-dev
</code>
===== Build paclink-unix =====
  * Before you build paclink-unix you need to know which [[plu:before_you_start#mta | MTA]] is installed & configure the build for that package
    * Set the proper command line args for sendmail
      * postfix & exim4 //sendmail// program use %%-bm%%
      * sendmail //sendmail// program uses -ba
      * See Makefile.am
      * no argument selects sendmail MTA <code>--enable-postfix</code> selects postfix MTA
    * find the version of //automake// you are using & copy the //missing// script locally
      * The version I have installed is 1.14
<code bash>
ls -l /usr/share/automake*
cp /usr/share/automake-1.14/missing .
./autogen.sh --enable-postfix
  ** ./configure not required if autogen.sh is run -> ./configure --enable-postfix
</code>
  * **Note:** if after running ./autogen.sh or ./configure and you see this line on the console:
<file>
config.status: error: cannot find input file: `Makefile.in'
</file>
  * then run these commands:
<code bash>
automake --add-missing
./configure --enable-postfix
</code>
  * Obviously only use the --enable-postfix if that is the [[plu:before_you_start#mta | MTA]] you selected (my preference).
  * Continue the build
<code bash>
make
sudo make install
</code>
  * need to run 'make install' as root
  * mail.wl2k should be in  /usr/local/libexec
  * Verify both wl2ktelnet & wl2kax25 are installed
<code bash>
whereis wl2ktelnet
whereis wl2kax25
</code>
===== A note about wl2kserial =====
  * Nick n2qz, the founder of paclink-unix, developed //wl2kserial// to interface to an SCS-PTC-IIpro modem using PACTOR III
====== After install need to do some config ======
  * Add user to the following groups, change username //<your_user_name>// to something appropriate.
<code bash>
usermod -a -G postdrop <your_user_name>
usermod -a -G mail <your_user_name>
usermod -a -G adm <your_user_name>
</code>
  * verify that user is in group //mail// by executing:
<code bash>
groups
</code>
  * As root set permissions in the outbox directory:
    * change //<your_user_name>// to something appropriate.
<code bash>
cd /usr/local/var/
chown -R <your_user_name>:mail wl2k
</code>
  * Edit paclink-unix config file in /usr/local/etc/wl2k.conf
  * uncomment lines that you edit
    * set //mycall// to your callsign & **use uppercase**
    * set //timeout// to 190
    * set //email// to <username>@localhost
    * set //wl2k-password// 
      * For official Winlink documentation go [[https://www.winlink.org/tags/password | here]] and look for the section that starts with:
<file>
If you’re using a different Winlink e-mail client program, you must follow these steps:
</file>
    * set ax25port to the //portname// in /etc/ax25/axports
  * All the rest of the defaults should be fine
