Mac openmodelica-devel with modelica3d fails to build

[Adam Dershowitz <dersh@…>]

I wanted to try to view some simulations. I am building on a Mac. I tried to build with:
sudo port install openmodelica-devel +modelica3d

But it gives a build error. I have attached the log file. It looks like the problem is that it is attempted to copy libproc3d.so and libm3d-osg-gtk.so but these are built with the common Mac name suffix of .dylib.

I also tried to run this simple example, without building with +modelica3d variant:
​https://build.openmodelica.org/Documentation/OpenModelica.Scripting.loadModelica3D.html

I just did the default install.
I didn't really expect it to work, but the error that I get is not a link error, so I'm not sure if it some part of modelica3d is already being built, or what exactly is happening with it:

I also have been building with the +libraries variant. So that means that I have omlib-modelicaservices-3.2.1-modelica3d installed. So, it is not clear if I do need to use the +modelica3d variant to not.
Are these two separate?
If I look at the list file->system libraries I don't see anything related to 3d.

[Martin Sjölund]

The libraries required for modelica3d are built by the openmodelica package (libmodcount, libmodbus, libproc3d) and is enabled by the +modelica3d flag.

[Adam Dershowitz <dersh@…>]

But, the build fails with +modelica3d.

[Martin Sjölund]

OK, that should work now. Close this if so.

[Adam Dershowitz <dersh@…>]

No. Not working. Now it seems to build, but won't install.

This looks a lot like this bug that showed up while trying to fix this, but then you were able to fix:
https://trac.openmodelica.org/OpenModelica/ticket/2701

[Martin Sjölund]

Similar, but different. In this case, the .dylib has already been linked against.

[Martin Sjölund]

I hope r21115 works because I should go prepare for a business trip early Sunday morning.

[Adam Dershowitz <dersh@…>]

I was out, and could not try it until now. But, it doesn't work. Upgrade, or install, both report:

Error: openmodelica-devel: Error executing modelica3d: can't set "depends_lib": invalid depspec: configure.args-delete
Error: Unable to open port: Error evaluating variants
To report a bug, follow the instructions in the guide:
    http://guide.macports.org/#project.tickets

Have a good business trip.

[Adam Dershowitz <dersh@…>]

Looks like it was just a typo. There was an extra end of line. This is in the Portfile:

  port:OpenSceneGraph \
configure.args-delete --disable-modelica3d

I changed deleted that line extension and now it builds:

  port:OpenSceneGraph 
configure.args-delete --disable-modelica3d

[Adam Dershowitz <dersh@…>]

It does seem to build fine, but I can't seem to get it to run. I'm not sure if this ticket is the best place for this, but here goes:
In order to get dbus-server.py to run I had to install the py27-gobject3 port (so this should probably be a dependent port). dbus-server.py as included, just checked for Mac and exited with a message about it being untested. So, I changed it to this:

elif (platform.system() == 'Darwin'):
    viewer = CDLL("/opt/local/lib/libm3d-osg-gtk.dylib")  # GTK/OSG backend
    proc3d = CDLL("/opt/local/lib/libproc3d.dylib") # procedural 3d

Now, I can run it, and I get a message. "Running dbus-server..."

Next, I ran OMEdit, I unloaded ModelicaServices and then loaded "ModelicaServices 3.2.1 modelica3d". I then try to run Modelica.Mechanics.MultiBody.Examples.Elementary.Pendulum and it builds and starts to simulate. But there is no progress in the simulation window. It just hangs like that until I hit cancel.

So, I think that the above steps are correct. I am not sure if I have made a mistake in my running process, or if there is a bug in the Mac build.

[Adam Dershowitz <dersh@…>]

Am I correct that ModelicaServices modelica3d should use dbus to connect to dbus-server.py. And, when run this way, the simulation will wait until it can successfully "talk". So, I think that the simulation is just not connecting, so it is just waiting to try before it can make any progress?

[Martin Sjölund]

This was fixed at some point... I think.

[Adam Dershowitz <dersh@…>]

Yes, this now works. Thanks.
