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

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

• autoconf, automake, libtool, g++, gfortran (pretty standard compilers)
• boost (optional; used with 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 and OMShell)
• OpenSceneGraph (optional, part of Modelica3D which should be compiled but is actually not yet compiled)
• Qt4, Webkit
• Sundials (optional; adds more numerical solvers to the simulation runtime)

$ autoconf
$ ./configure CC=clang CXX=clang++
$ make -j8
$ build/bin/omc --version
$ (cd testsuite/partest && ./runtests.pl -j8)

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=MyName ; git clone https://openmodelica.org/git-readonly/OpenModelica.git --recursive && (cd OpenModelica && git remote set-url --push origin [email protected]:$MY_FORK/OpenModelica.git && git submodule foreach --recursive 'git remote set-url --push origin `git config --get remote.origin.url | sed s,^.*/,[email protected]:'$MY_FORK'/,`')

To keep the project updated, use something like:

# Note: Changes the head to the latest one; your changes might be lost
git pull --recurse-submodules && git submodule update --recursive

If you have push access to the submodules, you can push them all together and let hudson run the tests before this project is updated (only necessary if you change an interface or the test suite at the same time as OMCompiler):

git submodule foreach --recursive "git push"

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"

git clone https://openmodelica.org/git-readonly/OpenModelica.git OpenModelica-minimal
cd OpenModelica-minimal
git submodule update --init --recursive libraries testsuite OMCompiler common
