[casper] Corr test

[Zhu Renjie]

Dear all,

  I try the basic ROACH board interaction. 
  When I instantiate an FpgaClient object with 'from corr import katcp_wrapper' 
with python. The error message is:

>>> from corr import katcp_wrapper
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.6/dist-packages/corr/__init__.py", line 11, in 
<module>
    import cn_conf, katcp_wrapper, log_handlers, corr_functions, corr_wb, 
corr_nb, corr_ddc, scroll, katadc, iadc, termcolors, rx, sim, snap
  File "/usr/local/lib/python2.6/dist-packages/corr/corr_functions.py", line 
53, in <module>
    import corr, time, sys, numpy, os, logging, katcp, struct, construct
ImportError: No module named construct

  How can I deal with this problem?


Best Regards
