3.3.7. Build on CentOS

This section describes how itom and its plugins are built on CentOS (tested with CentOS 7). For general information about building itom under linux, see the build instructions for linux.

In the following, all required steps are indicated to get the dependencies, get the sources and compile itom by the command line. The folder structure is chosen to be equal than the one from the linux instructions, however itom will only be build in a release version.

Please execute the following commands in the command line to get the dependencies for itom (comments after the hash-tag should not be copied to the command line):

sudo yum install epel-release
sudo yum install cmake3 cmake3-gui
sudo yum install git gcc gcc-c++
sudo yum install python36 python36-devel python36-numpy
sudo yum install opencv opencv-devel libv4l libv4l-devel
sudo yum install qt5-qtbase-gui qt5-qtwebkit qt5-qtwebkit-devel
sudo yum install qt5-qtsvg qt5-qtsvg-devel qt5-designer qt5-qttools-static qt5-qttools-devel

These dependencies does not include support for point cloud libraries. To enable this support, you have to get further packages. Please sett build on fedora for more hints.

Now, change to the base directory, where the sources and builds of itom and its plugins should be placed. The following commands are not executed with super-user rights; prepend sudo if this is required. In comparison to building itom under Debian based Linux versions, the CMake configuration process under CentOS needs some more hints about where to find some libraries etc. Therefore, it might be, that you have to adjust some pathes below. Currently, Qt5 is still built with webkit-support under CentOS, such that the WebEngine-support is not available. Therefore, the built-in helpviewer of itom has to be disabled. For building itom without point cloud support use:

mkdir itom
cd itom
mkdir sources
cd sources

git clone https://bitbucket.org/itom/plugins.git
git clone https://bitbucket.org/itom/designerplugins.git
