GEE Build Setup for CentOS 6, CentOS 7, RHEL 6, and RHEL 7

Enable Additional Repositories

Specific Yum repositories need to be enabled for different distributions to install the required development tools.

CentOS 7

sudo yum install epel-release

RHEL 7

sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

CentOS 6

wget http://people.centos.org/tru/devtools-2/devtools-2.repo -O /etc/yum.repos.d/devtools-2.repo
sudo yum install -y epel-release

RHEL 6

NOTE: The EPEL URL below assumes that your RHEL 6 installation has the latest updates.

# For RHEL 6 Workstation:
sudo subscription-manager repos --enable=rhel-x86_64-workstation-dts-2

# For RHEL 6 Server:
sudo subscription-manager repos --enable=rhel-server-dts2-6-rpms

# For all RHEL 6 Editions:
sudo subscription-manager repos --enable=rhel-6-server-optional-rpms
sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

Install Git

Install the system default version:

sudo yum install -y git

Alternatively, install the latest version from the IUS repository (recommended). See the Getting Started page to find the RPM URL for your system. Use this URL below:

sudo yum install -y wget
cd /tmp

# CentOS 7
wget https://centos7.iuscommunity.org/ius-release.rpm
sudo yum install -y ius-release.rpm
sudo yum install -y git2u-all

Install Git LFS

Execute the following commands:

curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.rpm.sh \
  | sudo bash
sudo yum install git-lfs

GCC 4.8

CentOS 7 and RHEL 7

yum install ant bzip2 doxygen gcc-c++ patch python-argparse python-setuptools \
  swig tar

CentOS 6

yum install -y devtoolset-2-gcc devtoolset-2-binutils devtoolset-2-toolchain devtoolset-2-gcc-gfortran

RHEL 6

sudo yum install -y devtoolset-2-gcc devtoolset-2-binutils \
  devtoolset-2-toolchain devtoolset-2-gcc-c++ devtoolset-2-gcc-gfortran

The GCC 4.8 installation will be located in the /opt/rh/devtoolset-2/root/usr/bin/ directory.

The GEE build scripts will detect this compiler automatically. However, if you wish to switch the environment to use GCC 4.8 in a shell, execute:

source /opt/rh/devtoolset-2/enable

Install additional packages

NOTE: If you are upgrading from GEE 5.1.3 or earlier, you must run this step after uninstalling older versions of GEE. Otherwise, some of the prerequisites will be missing and the build will fail.

CentOS 7 and RHEL 7

Execute:

sudo yum install -y scons perl-Perl4-CoreLibs xorg-x11-server-devel \
  python-devel perl-Alien-Packages openssl-devel libxml2-devel \
  libXinerama-devel libXft-devel libXrandr-devel libXcursor-devel gdbm-devel \
  libmng-devel libcap-devel libpng12-devel libXmu-devel freeglut-devel \
  zlib-devel libX11-devel bison-devel openjpeg-devel openjpeg2-devel \
  geos-devel proj-devel ogdi-devel giflib-devel xerces-c xerces-c-devel \
  cmake GitPython rpm-build rpmrebuild rsync

CentOS 6 and RHEL 6

Execute:

sudo yum install -y scons perl-Perl4-CoreLibs xorg-x11-server-devel \
  python-devel perl-Alien-Packages openssl-devel libxml2-devel \
  libXinerama-devel libXft-devel libXrandr-devel libXcursor-devel gdbm-devel \
  libmng-devel libcap-devel libpng-devel libXmu-devel freeglut-devel \
  zlib-devel libX11-devel bison-devel openjpeg-devel openjpeg2-devel \
  geos-devel proj-devel ogdi-devel giflib-devel xerces-c xerces-c-devel \
  cmake GitPython rpm-build rpmrebuild rsync shunit2 python-unittest2

If you encounter an error about git dependency conflicts, consider experimenting with the --skip-broken parameter.

GTest 1.8

CentOS 7 and RHEL 7

GTest is included in the EPEL and RHEL Extra Repositories. Install the RPM with:

yum install -y gtest-devel

CentOS 6 and RHEL 6

You will need to compile, package, and install an updated version of GTest as an RPM for RHEL6. This build process also depends on GCC 4.8, as does the rest of the GEE build process.

To clone this Git repository and build the RPM on RHEL6, execute the following:

mkdir -p ~/opengee/rpm-build/
cd ~/opengee/rpm-build/

git clone https://github.com/thermopylae/gtest-devtoolset-rpm.git

cd gtest-devtoolset-rpm/
./bin/build.sh --use-docker=no

NOTE: The GTest RPM can be built on other Linux systems using Docker. Simply execute build.sh without the --use-docker=no argument. See the README.md for more details.

Install the RPM:

sudo yum install -y ./build/RPMS/x86_64/gtest-devtoolset2-1.8.0-1.x86_64.rpm

shunit2

shunit2 is used for unit testing shell scripts in the GEE repository. It is currently used only for testing package-building scripts.

CentOS 7 and RHEL 7

The EPEL repositories for RHEL and CentOS 7 do not include shunit2. If you want to run these tests on one of these platforms, you must install shunit2 from the EPEL repositories for RHEL and CentOS 6. To do so run the following:

sudo yum install -y http://download-ib01.fedoraproject.org/pub/epel/6/x86_64/Packages/s/shunit2-2.1.6-3.el6.noarch.rpm

CentOS 6 and RHEL 6

shunit2 was installed in a previous step.
