Building LDMS For Generic Linux Distributions

Modify your build environment to use the gnu compiler

• Using the "module" command
  • module avail -- prints available modules
  • module list -- lists currently loaded modules
  • module unload <module name> -- unloads named module
  • module load <module name> -- loads named module
• Examples (actual file names and responses will be system dependent):

 $ module list
 Currently Loaded Modulefiles:
   1) intel/vtune/2017.0.2

 $ module unload intel

 $ module list
 No Modulefiles Currently Loaded.

 $ module load gcc
 $ module list
 Currently Loaded Modulefiles:
  1) binutils/2.26.0  2) gcc/6.2.0

• If not using "modules" then set PATH and LD_LIBRARY_PATH environment variables appropriately

Building LDMS and support libraries and headers

• Download ovis and gpcd from github.com/ovis-hpc
• Download libevent-2.0.x-stable from libevent.org
• In this example source files are assumed to be in ~/Source and builds in ~/Build

Building libevent-2.0

• cp <path>/libevent-2.0.x-stable.tar.gz ~/Source
• cd ~/Source
• untar libevent-2.0.x-stable.tar.gz
• cd libevent-2.0.x-stable
• Run autogen.sh

 ./autogen.sh

• Create config file with the following: -- in this example configure.sh

 ../configure --prefix=<absolute path>/Build/libevent-2.0_build

• make configure.sh executable

 chmod +x configure.sh

• Create a build directory

 mkdir build

• cd to build directory and run configure.sh

 cd build
 ../configure.sh

• Build and install libevent-2.0 libs and includes

 make && make install

Building LDMS

• cp <path>/ovis-master.zip ~/Source
• cd ~/Source
• unzip ovis-master.zip
• cd ovis-master
• Run autogen.sh

 ./autogen.sh

• Create config file with the following: -- in this example configure.sh

 #!/bin/bash
 #
 # SYNOPSIS: Remove existing build directories, do the automake routine, rebuild,
 #           and install everything.
 #
 # REMARK: This script doesn't do uninstall. If you wish to uninstall (e.g. make
 # uninstall), please go into each build directories ( */build-$HOSTNAME ) and
 # call make uninstall there, or just simply do the following
 #     for D in */build-$HOSTNAME; do pushd $D; make uninstall; popd; done;

• make configure.sh executable

 chmod +x configure.sh

• Create a build directory

 mkdir build

• cd to build directory and run configure.sh

 cd build

• Build and install ldms libs, executables, and includes

 make && make install

Running LDMS

• README files and sample scripts reside in the ovis-master/util/sample_init_scripts/XXX directory.
  • Note that the scripts must be modified, as described in the README file, to fit a particular deployment configuration.
