2. Installation

The installation instructions seem to change over time, so your best bet is to review the instructions at https://www.openmodelica.org/

Below are notes about issues when building for Mac OS X and Linux.

2.1 12/21/2015 Building OpenModelica Under Mac OS X 10.11.1 (El Capitan)

Mac: checking LAPACK/BLAS flags... configure: error: dgesv or dswap not found

While running ./configure ...:

Solution: Run ./configure with --with-lapack="-llapack -lblas"

Could not find qmake (QT4)

Solution:

 export PATH=/opt/local/libexec/qt4/bin:${PATH}

Installing via Macport does not include buildproject.

Installing with Macports as per https://openmodelica.org/download/download-mac results in an installation that cannot build fmus:

The workaround was to install and build from Github.

CMake Error at cmake/Config.cmake:11 (message): Unsupported version of OS X : 10.11.1

Solution: In OpenModelica/OMOptim/ParadisEO-2.0.1/cmake/Config.cmake, change:

     string(REGEX REPLACE "10\\.([0-9]).*" "\\1" MACOSX_VERSION "${MACOSX_VERSION_RAW}")

to:

     string(REGEX REPLACE "10\\.([0-9]*).*" "\\1" MACOSX_VERSION "${MACOSX_VERSION_RAW}") 

2.2 12/20/2015 Building OpenModelica Under RHEL 6.7

See Under RHEL, make install in OMCompiler failed for how to install.

Below are the various error messages I ran in to when determining the above.

Git fails with Error Setting Certificate Verify Locations

The message error setting certificate verify locations is from curl. My workaround was:

autoconf fails because common/m4/pre-commit.m4 is not found.

The OpenModelica/README.md file says to run autoconf:

This is because the OpenModelica repo is a superproject and requires further work.

The OpenModelica GitHub repo is a superproject, see https://github.com/OpenModelica/OpenModelica RHEL 6.7

The README.md file says

Configure fails with: Could not find qmake (QT4)

Under RHEL 6.7, configure fails:

Solution: Install qt4-devel

then

libomniORB4.so.2: cannot open shared object file: No such file or directory

While running make:

Solution:

Variable inVarInfo.numStateVars not found in scope SimCodeUtil.getDefaultValueReference

To replicate:

#2512 can't compile trunk because of template incompatibilities suggests removing rm build/bin/omc and then rerunning make, which seemed to work. #2512 suggests configuring with --without-omc, which we are already doing.

Under RHEL, make install in OMCompiler failed:

My workaround was to run make -n install and then run the remaining commands by hand:

2.3 5/11/2015 Updating under Linux

Log in to terra as the jenkins user

• I had to run autoconf because configure was failing with config.status: error: cannot find input file: PythonInterface/Makefile.in'
• I removed --without-rml because configure said configure: WARNING: unrecognized options: --without-rml

2.4 3/18/2015 Update OpenModelica from sources under Mac OS X
