Yade

Installation problem with libQt5OpenGL.so library.

Asked by A Dinesh

Hi all,

I had sucesfully compiled the source and installed yade on my system. I am using Ubuntu 16.04, with python 2.7, ubuntu distribution. After installation I tried to run the binary from install folder.

    import boot
ImportError: /usr/lib/x86_64-linux-gnu/libQt5OpenGL.so.5: undefined symbol: _Z12qTriangulateRK11QVectorPathRK10QTransformd
```

I don't know what's wrong with it. Some one please help.

Thank you.

I saw some answers about compiling it without the opengl extension. But can we make it work with it?

Try running yade as sudo. If it works, you need to modify permissions on your build libraries.

If it doesn't work. Reinstall/update libqt5. Remove your build tree. Re-cmake. Re-make install. Copy cmake output here.

Cheers,

Robert

Okay. I reinstalled qt5. I need to reinstall yade now, but for now here is the cmakw output

I have paraview installed in Documnets folder. Because I had it to update to a latest version. Do you think this creates any problem?

No sense in reinstalling until you get rid of the errors at the end of cmake :-).

>>Do you think this creates any problem?

Well, I want to say no, but it sure appears to be a problem. I would remove Paraview entirely from the computer and try cmake again.

 > runtime library [libexpat.so.1] in /usr/lib/x86_64-linux-gnu may be hidden by files in: /home/dinesh/Documents/Paraview/lib

I would guess you not only installed paraview in a custom path but you also built/installed third party libs in the same path, then declared this path system-wide somehow (e.g. by tricks in ~/.bashrc). Otherwise cmake would not find the wrong library versions.
I would rename Paraview folder to something else, then recompile. If it works it is your home folder which needs fix, since the problem may occur not only with yade.

Thanks for the answers. I removed paraview from path and did a reinstall. Now I get different error.

Let's take a step back.

Why do you need to compile from sources? Is it not enough to simply install the packaged version with

sudo apt-get install yade

>> sudo apt-get install yade

I even did that too. But want to integrate my research so I wanted to build it from source. I can do this later.

I have problem with yade too. When I am trying to view the simulation, I did F11, but I don't see any viewer. The terminal will
just become full screen.

And also to run a python script (bouncing ball exmaple), I tried

```
python bouncing_ball.py
```
I get 'O' is not defined error. I understand this. Yade interpreter by default creates a world O.
But I don't know how to run throught a script.

So you are able to install Yade successfully with sudo apt-get install yade? You can test this by typing "yade --checks" into your terminal.

I am happy to help you with your additional questions. But for organization in Yade's knowledge base, we ask that you separate questions into separate threads. In other words, you need to open a new thread for each of your disparate questions.

Please read through our How To Ask Document [1] if you hope to receive the most effective responses possible.

Thanks for the responses. I will reopen it when I want to build from source.

Please make sure you are speaking of a fresh build. Not rebuilt from the same folder after some changes.
To be sure make a new dir 'buildX' and append SUFFIX to yade built (-DSUFFIX="buildX").

Please answer the requests for more information. Namely #10: test this by typing "yade --checks" into your terminal." (with packaged version)
