Issue will running 2fallingcubes example.

[nburgessCarbon]

Hello,
When running the 2cubesFall.txt example. I get the following error : X11: The DISPLAY environment variable is missingThe GLFW library is not initializedThe GLFW library is not initializedThe GLFW library is not initializedSegmentation fault (core dumped). I think the problem may be that I'm running on a remote machine using a non-x11 terminal. Is there a way to disable the viz and have IPC dump files I can read in later?

Yes, you can use the option-DIPC_WITH_OPENGL=OFF with cmake or set it interactively with ccmake. The output files will be dumped into an output directory located in the directory you run IPC from.

Hi ,

I recompiled with -DIPC_WITH_OPENGL=OFF. But i am getting following message instead of GLFW
[2020-07-12 14:05:54.377] [critical] Not offiline mode supported only with opengl Segmentation fault (core dumped)

Ah, I forgot to mention that in order to run without the viewer you have to change the first argument to the IPC_bin. If the first argument is 10 it runs with the viewer and if it is 100 it runs without. If you compile with -DIPC_WITH_OPENGL=OFF then the only valid option is 100.

If you are using batch.py then change line 30 to:

runCommand += progPath + ' 100 ' + inputFolderPath + inputModelNameI + ' t' + numOfThreads

I will add a cmd-line option to that script to make it easier to choose.

I forgot to mention in my original reply that you only need to compile with -DIPC_WITH_OPENGL=OFF if your system does not have the necessary OpenGL libraries installed. If the compilation works with -DIPC_WITH_OPENGL=ON, then you can still run without the viewer using the above method.

In my latest commit (a02cad1), I added an --offline option to batch.py that runs IPC in offline mode. I also updated the README with the information I wrote above.

Thanks Zach, I'll be trying that tomorrow when I get to work.

Thank you, It worked.

Thanks Zach, everything works great now.
