Re: [Pytables-users] Indexed & .createIndex() runtime

[kevin l. <lke...@ya...>]

Hi Francesc,

First, let me say that the field variable change did
allow indexing.(thanks).
 
After My last email, I re-Installed all packages. At
first nothing worked. IDE's and DOS command executions
just crashed immediately. After Fooling around for
quite some time, I got things to work by not including
the SZLIB files(and .dll). 

But... PythonWin (which is the IDE I was using before
all this crashing) is still crashing. It was
performing before, but did need to be re-booted after
nearly each file upload. I don't necessarily care to
use it. Hopefully I'll find the stability in the IDE
I'm going to try to work with now (SPE).

Not being as computer savvy yet as I'm going to be
;-), I had trouble with knowing which of the
optionable versions of szlib I needed. But, is szlib
even necessary??? I did'nt get that impression from
HDF5's instructions.

At this point I was also able to utilize 'lzo' & 'ucl'
for compression.  

Anyway I'm going to see how things progress and I'll
give a report later.

Many, many thanks,
Kevin
