Succesfull installation of NI-VISA to my Ubuntu 14.04

[vatpatel]

I have installed NI-VISA to my Ubuntu 14.04, however when i open it it doesnt seem to recognice my equipments that are connected through gpib [this connection is recognized in terminal when i run "lsusb" command]. I might be missing some packages but at this point i have no idea what i'm missing. Any help would be appritiated. Thanks for your help in advance.

Hi,

If your Linux kernel is newer than 2.6.24, then GPIB USB support is not supported.

Check out these other threads for more details:

If this is the case with your system, other GPIB devices should still be supported (although we do not officially support Ubuntu)

Hi:

A consideration should be made to support both Redhat/Centos and Ubuntu streams.

Redhat/Centos has a large server based following and with its very controlled release structure has become a favorite for EDA vendors.

Ubuntu/Debian seems to have a large following in the embedded space.  Most users would choose to put this release on their lab laptop/netbook device.  Debian offers a much larger library of software packages than Redhat/Centos making it a very powerful base upon which to mash up solutions from the wide software basek.

Hey vatpatel,

actually I'm trying to install it on my ubuntu 14.04 but I'm getting this error

gcc	Not found in current path

*** ERROR: Some required tools are missing or were not found. ***

please can you help me ?

Hi Besmati:

gcc is installed by default in 14.04.  I'd need to see a full log as well as the $PATH variable of your current shell to comment further.

All:

I was able to get NI-Visa to install on my Ubuntu14.04 system....partially.

I can't recall what forum I followed, but by using "alien" I was able to convert the NI-Visa RPM's to .deb files.

The NI-VISA package is 32 bits.  This does not play nicely with pyVISA, if you are running on a 64 bit machine. 

Is there any reason why NI-VISA for linux cannot be compiled for 64 bit machines?

I am considering creating a 32 bit Ubuntu 14.04 virtual machine, if only to test the link between pyVISA and the NI-VISA packages...... of course this won't connect me to real hardware......

You could try to install a 32-bit version of Python. It's a long process, but its doable in Ubuntu and you don't have to sacrifice any other software that supports Python x64.

The alternative I ended up using was to write C programs and control them with Python via popen, etc.

This is strange. I installed NI-VISA in ubuntu 16.04, it worked, I caould connect to my tektronix, but could not read or write anything. But,today when I tried again, nothing worked, Idont think it loaded the modules. So tried to reinstall everything but it doesnt work anymore. Very strange. I haveno idea why it worked or why it doesnt work anymore. I installed it with

"

"sudo apt-get install alien"    to be able to install rpm:s

and then

"sudo ./INSTALL --nodeps"
