OpenModelica

OpenModelica is an open-source Modelica-based modeling and simulation environment intended for industrial and academic usage.

Dependencies (Linux/OSX)

Many software packages are included inside the repositories. To get everything running, you will need a few extras:

• C++11 compiler (if you want a GUI)
• autoconf, automake, libtool, g++, gfortran (pretty standard compilers)
• boost (used by omsimulator and cppruntime, configure --with-cppruntime)
• clang, clang++ (optional, but highly recommended)
• cmake
• hwloc (optional; queries the number of hardware CPU cores instead of logical CPU cores)
• Java JRE (JDK is option; compiles the Java CORBA interface)
• Lapack/BLAS
• lpsolve55
• libhdf5 (optional part of the MSL tables library supported by few other Modelica tools, so it does not do much)
• libexpat (it's actually included in the FMIL sources which are included... but we do not compile those and it's better to use the OS-provided dynamically linked version)
• ncurses, readline (optional, used by OMShell-terminal)
• omniORB (optional; CORBA is used by OMOptim)
• OpenSceneGraph
• Qt5 or Qt4, Webkit, QtOpenGL
• Sundials (optional; adds more numerical solvers to the simulation runtime)

Compilation

The OpenModelica Compiler is the core of the OpenModelica project, which is an open-source Modelica-based modeling and simulation environment intended for industrial and academic usage.

Building the OpenModelica Compiler

• Linux/OSX instructions
• Windows instructions
• Windows Subsystem for Linux

Working with the repository

OpenModelica.git is a superproject. Clone the project using one of:

# Faster pulling by using openmodelica.org read-only mirror (low latency in Europe; very important when updating all submodules)
# Replace the openmodelica.org pull URL with https://github.com/OpenModelica/OpenModelica.git if you want to pull directly from github
# The default choice is to push to your fork on github.com (SSH). Replace MY_FORK with OpenModelica to push directly to the OpenModelica repositories (if you have access)
> MY_FORK=MyGitHubUserName ; git clone https://openmodelica.org/git-readonly/OpenModelica.git --recursive && (cd OpenModelica && git remote set-url --push origin git@github.com:$MY_FORK/OpenModelica.git && git submodule foreach --recursive 'git remote set-url --push origin `git config --get remote.origin.url | sed s,^.*/,git@github.com:'$MY_FORK'/,`')

If you are a developer and want to track the latest heads, use:

# After cloning
> git submodule foreach --recursive "git checkout master"
# To update; you will need to merge each submodule, but your changes will remain
> git submodule foreach --recursive "git pull"

In order to push to the repository, you will push to your own fork of OpenModelica.git, etc. You will need to create a fork of each repository that you want to push to (by clicking the Fork button in the GitHub web interface).

If you do not checkout the repositories for GUI clients (such as OMOptim.git), these directories will be ignored by autoconf and skipped during compilation.
