surf1 example: dynamic module does not define init function (initlibyade) about dem-fem-coupling

[stranskyjan]

ImportError: dynamic module does not define init function (initlibyade)

this indicates that python tries to import some shared library libyade, not the intended libyade.py from demfem/install directory

Do you have another Yade installed on the system?

[zoheir1928]

I do not think so! is there a way to make sure there is only one Yade installed?
Can you think of any other reason behind this error?
Much appreciated

what is the output of terminal commands:

sudo updatedb
locate libyade

?

Here is the output:

[stranskyjan]

it seems python is trying to import one of libyade.so files instead of libyade.py file..

could you try instead of

import libyade

use

import imp
libyade = imp.load_source("libyade","/home/zoheir/FEMDEM/Installation/_build/install/libyade.py")

?

This time, it could not find "libyade.py" with an error: No such file or directory. There was a broken symbolic link.
I tried re-installing the codes using your makefile that I remembered during my first installation, I came across this error:

Before, I just made the directory (/_build/oofem/build/_build/oofem/source) and copied the source code from "/_build/oofem/build/source" to it in order to make it work. Looking back, it might have not been such a good idea. This error came up during the installation of both Yade and OOFEM.

Any ideas why makefile looks for "/_build/oofem/build/_build/oofem/source" instead of "_build/oofem/source"?

[stranskyjan]

Sorry, I tried it with different, but not the default location. Now it should work

[zoheir1928]

I re-installed the code successfully.

Thanks
