Mac OMEdit doesn't start

[Adam Dershowitz]

I have openmodelica-devel installed, using macports on my Mac.
Recent versions were working. But, upgrades over the last little while build and install, but if I try to run OMEdit, it does not open and I get the following error:

It looks like the port is failing to install a required library, or not linking it correctly.

[Martin Sjölund]

I'll add Lennart and Adeel here since they're the ones adding OMSimulator to the makefiles. I assume they forgot to add it to make install...

[Lennart Ochel]

I don’t know anything about Mac OSX specific requirements. For me it works at least to build and run OpenModelica and OMSimulator from source.

[Adam Dershowitz]

It seems that OMSimulator is being built, but not being properly linked for a Mac, so that is why OMEdit won't run. I'm not sure why, or where it is supposed to happen in the port file, so I'm not sure about the correct fix. But, the following is a wor- around that makes it work, and should also provide a clue:

sudo install_name_tool -change libOMSimulatorLib.dylib /opt/local/lib/libOMSimulatorLib.dylib /Applications/MacPorts/OMEdit.app/Contents/MacOS/OMEdit
sudo install_name_tool -change MAC64/libomtlmsimulator.dylib /opt/local/lib/libomtlmsimulator.dylib /Applications/MacPorts/OMEdit.app/Contents/MacOS/OMEdit
sudo install_name_tool -change MAC64/libomtlmsimulator.dylib /opt/local/lib/libomtlmsimulator.dylib /opt/local/lib/libOMSimulatorLib.dylib

So, the libraries: libomtlmsimulator.dylib and libOMSimulatorLib.dylib are being installed into /opt/local/lib, but OMEdit (and libOMSimulatorLib.dylib) are then searching in wrong places for them (and in two slightly different places, note "MAC64").
After doing the above I can run OMEdit. It seems like this is a similar problem to what was going on with these old tickets:
https://trac.openmodelica.org/OpenModelica/ticket/2680
https://trac.openmodelica.org/OpenModelica/ticket/3378

Martin, whatever magic you did for those, I'm sure that something similar is what it will take to get these two libraries to be found by OMEdit.

I believe this issue is no longer valid. Feel free to reopen the ticket.
