Floating point exception core dumped about dex-net HOT 6 OPEN

I have the exact same issue...

from dex-net.

I have exactly the same problem.

from dex-net.

Great, we are starting to make some progress. Looks like you are missing some necessary GL libraries.

This link suggests the following command:

sudo apt-get install libxmu-dev libxi-dev

@maxixb Can you run this command and try to compile again? Let me know if you have any errors.

from dex-net.

I suspect the meshrender binary didn't install properly. Let's see if you can find the binary

Open a Python terminal and find the location of meshpy

python
>>> import meshpy
>>> print meshpy.__file__

Then look for the file meshrender.so in the directory that is printed from the above statements.

If you do not find it, then your build failed. Change directories to /path/to/meshpy/clone and run the commands in this file from the command line. Paste any errors here.

from dex-net.

At first thank you for fast reply.
You are right, the problem ist meshrender.so file, it dosn´t exist.
I tried to run the comands like you sad, but i get instant an error if i run cmake ...

Great, it worked! Thank you!
But now I have trouble with the comand make...

I get this output...
