OK , thanks!

I precise also that package corr 0.6.5 installs well under Windows ,and not corr 0.6.9 (because of spead module with C extensions)

Hi,
For anyone who runs into these dependency problems: Please note that
you can simply install the katcp_wrapper.py file into your python path
and it will work independently of the rest of corr (you'll still need
katcp installed of course). You can then use the functions simply by
doing:

import katcp_wrapper
fpga = katcp_wrapper.FpgaClient(....

Hi Jason,

SPEAD seems unfortunately mandatory, even for basic FPGA interfacing

I doubt you'll get SPEAD compiled for Windows! Fortunately, you don't
actually need SPEAD to use the basic FPGA interfacing functionality of corr.
But if you want to use corr to control a packetised correlator, then you'll
want the SPEAD metadata to be issued.

Thanks Jason.
I have still a problem with python package spead-0.4.0 installation:
Lot of things due to Windows C++ compiler, not found .h files, and so on....

Would you have an example of a Windows configuration, which works well, to
install spead  (and its C dependencies) and then be able to use corr
package?

You don't need to use all of corr. The package will install without any of
the dependancies. But if you try to do "import corr", you will get
dependency errors. Instead, try "from corr import katcp_wrapper". Then do
myfpgaobject=katcp_wrapper.FpgaClient...

Detailed requirements and explanations can be found here:

Hi,

I want to configure a Roach 2 board from Python(2.7)/Windows 7
I intend to use Python Corr package.
There are a lot of Python packages dependencies, it seems that Coor package
can make a lot of sophisticated things and I want to do only basic
configuration: load a firmware, and that's all for the moment.

I will have to do that with others Windows PC.
Does a minimal Python package exists to do that, with a minimum additionnal
packages to install ?

Thanks a lot for your informations !

Patrice
