GeoModelExamples

GeoModelExamples contains example programs showing how to use the GeoModel libraries and tools.

Please, refer to the instructions contained in the single subfolders to build specific examples.

Dependencies

Qt5

Please, refer to the notes in the Appendix, at the bottom of this page.

GeoModelCore

You can install the packaged version of the GeoModelCore library by following the instruction in the package repository:

https://gitlab.cern.ch/GeoModelDev/GeoModelCore

Alternatively, and only if you are interested in developing the base libraries or a packaged version is not available for your system, you can build a fresh local copy from the HEAD by using the CMake's CMAKE_INSTALL_PREFIX variable, as below:

git clone ssh://git@gitlab.cern.ch:7999/GeoModelDev/GeoModelCore.git
mkdir build_gmcore
cd build_gmcore
cmake -DCMAKE_INSTALL_PREFIX=../install -DCMAKE_BUILD_TYPE=RelWithDebInfo ../GeoModelCore
make -j 4
make install

GeoModelIO

You can install the packaged version of the GeoModelCore library by following the instruction in the package repository:

https://gitlab.cern.ch/GeoModelDev/GeoModelCore

Alternatively, and only if you are interested in developing the base libraries or a packaged version is not available for your system, you can build a fresh local copy from the HEAD by using the CMake's CMAKE_INSTALL_PREFIX variable, as below:

git clone ssh://git@gitlab.cern.ch:7999/GeoModelDev/GeoModelIO.git
mkdir build_gmio
cd build_gmio
cmake -DCMAKE_INSTALL_PREFIX=../install -DCMAKE_BUILD_TYPE=RelWithDebInfo ../GeoModelIO
make -j 4
make install

Build

You can build all the examples together by issuing the command below from your work folder. If you built a local version of the GeoModelCore and GeoModelIO libraries, then they will be taken into account during the build (because of the -DCMAKE_INSTALL_PREFIX=../install statement).

git clone ssh://git@gitlab.cern.ch:7999/GeoModelDev/GeoModelExamples.git
mkdir build_hellogeo
cd build_hellogeo
cmake -DCMAKE_INSTALL_PREFIX=../install ../GeoModelExamples
make -j4

You can also build a single example, by addressing its source folder instead of the top one, as in the example below:

cmake -DCMAKE_INSTALL_PREFIX=../install ../GeoModelExamples/HelloGeoWrite

Run

You can run the example by launching them from their "build" directory, for example:

./HelloGeoWrite/hellogeoWrite

Visualization

You can visualize it by opening it with VP1Light. Please refer to the Visualization documentation.

Appendix

Notes on Qt5

To build and run GeoModel I/O libraries, you must have a working Qt5 installation on your computer. Qt5 classes are used for I/O operations with the underlying SQLite daemon, to store/handle data, and to handle logging.

If you are not sure how to install it, please take a look at the notes on Qt5, in the GeoModelIO repository.
