Hello!
I have been researching about GUI for control systems and found Taurus framework. One of the dependencies of this framework is PyTango. Tango is installed here but PyTango is not compiling.

I am working on a Linux RHEL 6.
I first tried PyTango 8.1.8 with Tango 9.2.2, but I got many errors, so I followed an advice to use Tango A.B.x with PyTango A.B.y.

Thus I tried PyTango 8.1.8 with Tango 8.1.2 and it turned out to be better, but then I got errors with vars not declared.

I am now trying to compile PyTango 8.1.2 with Tango 8.1.2.
However, I am still having errors with vars not declared.

This is the following issue during PyTango compilation:

$ cd PyTango-8.1.2

$ python2.7 setup.py build

<...compilation goes ok but then: >

<.. more similar error>

Actuallly I had this same issue with the var PyCmd in src/boost/cpp/server/device_class.cpp and I solved it with adding an #include "command.h" (because PyCmd is declared there), but it is strange to change the source code to make it compile.

Can I get any help in this case?

Thanks in advance!

Dear Lais,

I am in now way an expert in PyTango and Taurus (our local expert is out of town) but have you tried to install PyTango from PyPi?

Indeed PyTango 8.x will not work with Tango 9.x. There is a pre-release of PyTango 9.2 on github (https://github.com/tango-cs/PyTango/tree/tango9).

Have you tried that? I hope you have some success soon ...

Kind regards
Andy
