GeoModelIO

GeoModelIO contains all tools needed to read and write the persistent GeoModel tree data from and to file.

Quick Installation

On macOS and Ubuntu you can quickly install the pre-compiled library, with all the dependencies.

macOS

brew tap atlas/geomodel https://gitlab.cern.ch/GeoModelDev/packaging/homebrew-geomodel.git
brew install geomodelio

on macOS Mojave, the command above will install pre-compiled binaries, so the installation is quick. On other macOS versions, brew will build the library from its source code.

Ubuntu

sudo add-apt-repository ppa:kaktusjoe/geomodel

sudo apt-get update

sudo apt install geomodel-io-dev

Build

If you want to work on the library code, you have to build it by yourself.

First, install or build the GeoModelCore dependency, by following its instructions.

Then, get the code of this library and compile it:

git clone https://gitlab.cern.ch/GeoModelDev/GeoModelIO.git
mkdir build_geomodelio
cd build_geomodelio
cmake ../GeoModelIO
make

Local 'install' path

If you want to build a custom version of the library to be used to develop client code, you can create a self-contained area by defining a local install path; you can do it by adding the option -DCMAKE_INSTALL_PREFIX=../install when running CMake:

cmake -DCMAKE_INSTALL_PREFIX=../install ../GeoModelIO
make
make install

The make install command will install the headers and the shared libraries into the ../install folder. Then, use the same -DCMAKE_INSTALL_PREFIX=../install when compiling your client code, to let it find the custom version of the GeoModelIO library.
