How to install PBS using the configure script.

0. Disable SELinux.

  OpenPBS does not support SELinux. With SELinux enabled, initial start fails
    with datastore permission error. You can also define proper policy but it is
    out of scope of this guide.

1. Install the prerequisite packages for building PBS.

  For CentOS-8 systems you should configure and enable powertools
  repo for hwloc-devel and libedit-devel packages.

  You should run the following commands as root:

    dnf install -y dnf-plugins-core
    dnf config-manager --set-enabled powertools

    dnf install -y gcc make rpm-build libtool hwloc-devel \
      libX11-devel libXt-devel libedit-devel libical-devel \
      ncurses-devel perl postgresql-devel postgresql-contrib python3-devel tcl-devel \
      tk-devel swig expat-devel openssl-devel libXext libXft \
      autoconf automake gcc-c++ cjson-devel

  For CentOS-7 systems you should run the following command as root:

    yum install -y gcc make rpm-build libtool hwloc-devel \
      libX11-devel libXt-devel libedit-devel libical-devel \
      ncurses-devel perl postgresql-devel postgresql-contrib python3-devel tcl-devel \
      tk-devel swig expat-devel openssl-devel libXext libXft \
      autoconf automake gcc-c++

  For openSUSE systems you should run the following command as root:

    zypper install gcc make rpm-build libtool hwloc-devel \
      libX11-devel libXt-devel libedit-devel libical-devel \
      ncurses-devel perl postgresql-devel postgresql-contrib python3-devel tcl-devel \
      tk-devel swig libexpat-devel libopenssl-devel libXext-devel \
      libXft-devel fontconfig autoconf automake gcc-c++ cJSON-devel

  For Debian systems you should run the following command as root:

    apt-get install gcc make libtool libhwloc-dev libx11-dev \
      libxt-dev libedit-dev libical-dev ncurses-dev perl \
      postgresql-server-dev-all postgresql-contrib python3-dev tcl-dev tk-dev swig \
      libexpat-dev libssl-dev libxext-dev libxft-dev autoconf \
      automake g++ libcjson-dev

  For Ubuntu-18.04 systems you should run the following command as root:

    apt install gcc make libtool libhwloc-dev libx11-dev \
      libxt-dev libedit-dev libical-dev ncurses-dev perl \
      postgresql-server-dev-all postgresql-contrib python3-dev tcl-dev tk-dev swig \
      libexpat-dev libssl-dev libxext-dev libxft-dev autoconf \
      automake g++

  For macOS systems using MacPorts you should run the following command as root:

    port install autoconf automake libtool pkgconfig \
      expat hwloc libedit libical openssl postgresql14 python310 \
      swig-python tcl tk xorg-libX11 xorg-libXt

2. Install the prerequisite packages for running PBS. In addition
  to the commands below, you should also install a text editor of
  your choosing (vim, emacs, gedit, etc.).

  For CentOS systems you should run the following command as root:

    yum install -y expat libedit postgresql-server postgresql-contrib python3 \
      sendmail sudo tcl tk libical chkconfig cjson

  For openSUSE systems you should run the following command as root:

    zypper install expat libedit postgresql-server postgresql-contrib python3 \
      sendmail sudo tcl tk libical1 libcjson1

  For Debian (jessie) systems you should run the following command as root:

    apt-get install expat libedit2 postgresql python3 postgresql-contrib sendmail-bin \
      sudo tcl tk libical1a

  For Debian (stretch) systems you should run the following command as root:

    apt-get install expat libedit2 postgresql python3 postgresql-contrib sendmail-bin \
      sudo tcl tk libical2

  For Debian (buster) systems you should run the following command as root:

    apt-get install expat libedit2 postgresql python3 postgresql-contrib sendmail-bin \
      sudo tcl tk libical3 libcjson1

  For Ubuntu-18.04 systems you should run the following command as root:

    apt install expat libedit2 postgresql python3 postgresql-contrib sendmail-bin \
      sudo tcl tk libical3 postgresql-server-dev-all

  For macOS systems using MacPorts you should run the following command as root:

    port install expat libedit libical openssl postgresql14-server python310 \
      tcl tk

3. Open a terminal as a normal (non-root) user, unpack the PBS
  tarball, and cd to the package directory.

    tar -xpvf openpbs-20.0.0.tar.gz
    cd openpbs-20.0.0

4. Generate the configure script and Makefiles. (See note 1 below)

    ./autogen.sh

5. Display the available build parameters.

    ./configure --help

6. Configure the build for your environment. You may utilize the
  parameters displayed in the previous step. (See note 2 below)

  For CentOS and Debian systems you should run the following
  command:

    ./configure --prefix=/opt/pbs

  For openSUSE systems (see note 3 below) you should run the
  following command:

    ./configure --prefix=/opt/pbs --libexecdir=/opt/pbs/libexec

  For macOS systems using MacPorts you should run the following commands:

    export CPATH=/opt/local/include/postgresql14:/opt/local/include
    export LIBRARY_PATH=/opt/local/lib/postgresql14:/opt/local/lib
    ./configure --with-swig=/opt/local --with-tcl=/opt/local

  If PTL needs to be installed along with PBS use the option
  "--enable-ptl" (see note 5 below)
    eg ./configure --prefix=/opt/pbs --enable-ptl

7. Build PBS by running "make". (See note 4 below)

    make

8. Configure sudo to allow your user account to run commands as
  root. Refer to the online manual pages for sudo, sudoers, and
  visudo.

9. Install PBS. Use sudo to run the command as root.

    sudo make install

10. Configure PBS by executing the post-install script.

    sudo /opt/pbs/libexec/pbs_postinstall

11. Edit /etc/pbs.conf to configure the PBS services that
  should be started. If you are installing PBS on only
  one system, you should change the value of PBS_START_MOM
  from zero to one. If you use vi as your editor, you would
  run:

    sudo vi /etc/pbs.conf

12. Some file permissions must be modified to add SUID privilege.

    sudo chmod 4755 /opt/pbs/sbin/pbs_iff /opt/pbs/sbin/pbs_rcp

13. Start the PBS services.

    sudo /etc/init.d/pbs start

14. All configured PBS services should now be running. Update
  your PATH and MANPATH variables by sourcing the appropriate
  PBS profile or logging out and back in.

  For Bourne shell (or similar) run the following:
    . /etc/profile.d/pbs.sh

  For C shell (or similar) run the following:
    source /etc/profile.d/pbs.csh

15. You should now be able to run PBS commands to submit
  and query jobs. Some examples follow.

bash$ qstat -B

--------------------------------------------------------------------

NOTES:

Note 1: If you modify configure.ac or adjust timestamps on any files
  that are automatically generated, you will need to regenerate them
  by re-running autogen.sh.

Note 2: It is advisable to create a simple shell script that calls
  configure with the appropriate options for your environment. This
  ensures configure will be called with the same arguments during
  subsequent invocations. If you have already run configure you can
  regenerate all of the Makefiles by running "./config.status".
  The first few lines of config.status will reveal the options that
  were specified when configure was run. If you set envirnment
  variables such as CFLAGS it is best to do so as an argument to
  configure (e.g. ./configure CFLAGS="-O0 -g" --prefix=/opt/pbs).
  This will ensure consistency when config.status regenerates the
  Makefiles.

Note 3: The openSUSE rpm package expands %_libexecdir to /opt/pbs/lib
  rather than /opt/pbs/libexec which causes problems for the post-
  install scripts. Providing the --libexecdir value to configure
  overrides this behavior.

Note 4: You need to use a POSIX (or nearly POSIX) make. GNU make
  works quite well in this regard; BSD make does not. If you are
  having any sort of build problems, your make should be a prime
  suspect. Tremendous effort has been expended to provide proper
  dependency generation and makefiles without relying on any
  non-POSIX features. The build should work fine with a simple call
  to make, however, complicating things by using various make flags
  is not guaranteed to work. Don't be surprised if the first thing
  that make does is call configure again.

Note 5: PTL gets installed in the parent directory of where PBS
  is installed. For example if you have given install prefix=/opt/pbs, then
  you can find PTL installation in the directory /opt/ptl . You may need to
  log out and log in from the terminal for PATH and PYTHONPATH to update.



Using valgrind with PBS.
-------------------------------------
Here is a set of steps to detect memory errors/leaks within PBS code.

1. Install the valgrind development package.

   yum install valgrind-devel (zypper for OpenSUSE).


2. Compile Python in a way that valgrind can work with it, as follows:

   ./configure --prefix=<installdir> --without-pymalloc --with-pydebug --with-valgrind
   make; make install


3. Compile PBS with the special python and in debug mode as follows:

   ./configure --prefix=<installdir> --with-python=<python-dir>  CFLAGS="-g -DPy_DEBUG -DDEBUG -Wall -Werror"


4. Run pbs daemons under valgrind.

   a) To detect memory errors (not leaks) run pbs daemons as follows:

   export LD_LIBRARY_PATH=/opt/pbs/pgsql/lib:/opt/pbs/lib:$LD_LIBRARY_PATH
   valgrind --tool=memcheck --log-file=/tmp/val.out /opt/pbs/sbin/pbs_server.bin


   b) To detect memory leaks use the supplied leaks suppression file valgrind.supp, as follows:

   export LD_LIBRARY_PATH=/opt/pbs/pgsql/lib:/opt/pbs/lib:$LD_LIBRARY_PATH
   valgrind --tool=memcheck --log-file=/tmp/val.out --suppressions=./valgrind.supp --leak-check=full --track-origins=yes /opt/pbs/sbin/pbs_server.bin
