libres

libres is part of the ERT project: Ensemble based Reservoir Tool.

Building libres

1. Build libecl

Build and install libecl. When configuring libecl you should used the option -DCMAKE_INSTALL_PREFIX to tell cmake where to install libecl. The value passed to CMAKE_INSTALL_PREFIX will be needed when running cmake to configure libres in point 4 below. For now let us assume that the prefix /local/ert/install was used.

2. Install Python dependencies

pip install -r requirements.txt 

3. Update environment variables

To ensure that the build system correctly finds the ecl Python package you need to set the environment variables PYTHONPATH and LD_LIBRARY_PATH to include the libecl installation:

bash% export LD_LIBRARY_PATH=/local/ert/install/lib64:$LD_LIBRARY_PATH
bash% export PYTHONPATH=/local/ert/install/lib/python2.7/site-packages:$PYTHONPATH

Observe that path components lib64 and lib/python2.7/site-packages will depend on your Python version and which Linux distribution you are using. The example given here is for RedHat based distributions.

4. Run cmake to configure libres

When running cmake you must tell cmake where the libecl code is located with -DCMAKE_PREFIX_PATH and also where some Python/cmake interoperability modules are found with -DCMAKE_MODULE_PATH, i.e. in addition to other possible arguments you must at least add:

-DCMAKE_PREFIX_PATH=/local/ert/install \
-DCMAKE_MODULE_PATH=/local/ert/install/share/cmake/Modules \

in addition you probably want to pass -DCMAKE_INSTALL_PREFIX to configure where the libres distribuion should be installed, normally that will be the same location where you have already installed libecl.

5. Run make to compile libres

After you have run cmake you should run make and make install to build and install libres:

bash% make
bash% make install
