FMU Built with CPP under Linux

[weber@…]

Hey,

we tried to build an FMU compiled in cpp under the OpenmodelicaVM (and on Ubuntu) delivered on the webpage using omc fmu.mos

Basically we are missing two folders:

• /usr/lib/x86_64-linux-gnu/omc/cpp
• /usr/include/omc/cpp

It works on windows and copying the include folder from windows solves compilation errors, but leaving us with the linker errors.

DETAILS

with fmu.mos:

loadModel( grid); getErrorString();
setCommandLineOptions("-d=newInst"); getErrorString();
setCommandLineOptions("-d=initialization"); getErrorString();
setCommandLineOptions("--simCodeTarget=Cpp"); getErrorString();
setCommandLineOptions("-d=-disableDirectionalDerivatives"); getErrorString();
translateModelFMU(grid.network); getErrorString();

grid.network should be exported as FMU

Strange, I guess it doesn't install the cpp runtime?
Adding apt-get install libomccpp should fix it.

I now added that when installing omc in the VM.
Let's see on the next build if you will have that.

You can also do it in the current VM you have to install the CPP runtime if you want:
sudo apt-get install libomccpp
