ImportError: libDummyDevice.so.0: cannot open shared object file: No such file or directory #70

Open wd15 opened 9 years ago

wd15 commented 9 years ago

When importing the pcl Python library the following happens

 >>> import pcl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/dwheeler/anaconda/lib/python2.7/site-packages/pcl/__init__.py", line 2, in <module>
    from ._pcl import * 
ImportError: libDummyDevice.so.0: cannot open shared object file: No such file or directory

The OS is Ubuntu 14.04. PCL was installed using the instructions in http://pointclouds.org/downloads/linux.html. pcl-python was installed from f17c686b63fe. Some more information,

 $ ldd _pcl.so
 linux-vdso.so.1 =>  (0x00007ffcc290b000)
 libpcl_io.so.1.7 => /usr/lib/libpcl_io.so.1.7 (0x00007fd39dede000)
 libOpenNI.so.0 => /usr/lib/libOpenNI.so.0 (0x00007fd39dc65000)

Follow up comment: setting

$ export LD_LIBRARY_PATH=/usr/lib/OpenNI2/Drivers/

allows the import pcl to work and the examples work.

I have the same problem, but the above does not work

ldd _pcl.so gives the libDummyDevice.so.0 is found, after running

export LD_LIBRARY_PATH=/usr/lib/OpenNI2/Drivers/

but within with python I still get

ImportError: libDummyDevice.so.0: cannot open shared object file: No such file or directory.

Any ideas why?

Hi strawlab,

from ._pcl import * ImportError: libDummyDevice.so.0: cannot open shared object file: No such file or directory

I am stuck on this for last 3 days. Any help is appreciated.

Thank you,

Thank you
