Hi All
I'm feeling like a Luddite here! I've used pyvisa before on a windows
machine, but am now trying to get it running on Ubuntu (9.10).
At first I tried some of the National Instruments links, but
eventually got a response suggesting the linux-GPIB-drivers. These I
installed along with the python components using synaptic.
I then installed pyvisa, and got the following:
*******************************************************************
>>> import visa
Traceback (most recent call last):

return self._dlltype(name)
File "/usr/lib/python2.5/ctypes/__init__.py", line 348, in __init__
self._handle = _dlopen(self._name, mode)
OSError: /usr/local/vxipnp/linux/bin/libvisa.so.7: cannot open shared
object file: No such file or directory
******************************************************************
It seems that the /usr/local/vxipnp/linux/bin/libvisa.so.7 file is
important, and I get the impression that if I were ever lucky enough
to stumble through an NI installation that file might be created.
Anyway, let me quickly say what I'm trying to do. I have a national
instruments GPIB-USB-HS, and I want to control some standard GPIB
devices using python. I'm running a laptop with Ubuntu 9.10 on it.
Many thank!
