OK to use GPLed class libraries in DNA sequencers ( was Re: [dna-dev] Required headers on all files)

[Gregory Haber]

Hi Randall,

  I've made a first pass at DNA-105 (delimited text sequencer).  In it I
use the Ostermiller Utils classes
(http://ostermiller.org/utils/download.html) to do the delimited text
parsing.

Before I do any more work on it (and "officially" pick it up from the
JIRA queue), though, it occurred to me - these classes are GPL, where
DNA is LGPL.

Is it OK to build sequencers using class libraries that are GPL? or do
they need a less restrictive license like LGPL or Apache?

It isn't a problem to implement this individual connector (there are
lots of good delimited text parsing classes out there under a variety of
licenses - and although this is something I could do myself, this
parsing is actually a lot more difficult a problem than it appears
initially, so I would prefer not to do it), but I was curious as to
whether using GPLed libraries is OK.

Thanks,

Greg
