Stephan, The changes you checked in seem to have solved this problem. Thanks for taking care of this!

Is there a preferred branch > or version of LKB for building cheap? the no-MRS problem is unrelated to selective unpacking (in fact i had noticed it several months ago, but not needing to extract MRSs in PET, i did not find time to look into it until today).  both ann and i have made non-trivial changes to the MRS Lisp library, and unfortunately we do not always have the time or opportunity to test against PET. the problem you encountered is vaguely interesting.  we had introduced a call to vsym() where its argument was a symbol (`ING') rather than a string.  the LKB implementation of vsym() is robust to such variation, but the PET-side implementation was not.  lacking a full specification of the interface, neither side is to blame :-). i just checked in a few changes in `pet- interface.lisp' (making vsym() more accomodating) and `mrsoutput.lisp' (converting `ING' to a string), so once you update from CVS or fetch the latest `test' build, i expect the problem should disappear. at the same time, PET will then support a new output format: `mrs=mrx' should yield MRS output in XML (as provided by ann).  finally, i added some debugging code in `pet-interface.lisp': once the ECL MRS library is compiled with the :debug feature on, it will write a trace of calls back from ECL into the PET core as the file `/tmp/mrs.debug'.                                                      all best  -  oe +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +++ Universitetet i Oslo (IFI); Boks 1080 Blindern; 0316 Oslo; (+47) 2284 0125 +++     CSLI Stanford; Ventura Hall; Stanford, CA 94305; (+1 650) 723 0515 +++       --- <a href="mailto:oe@csli.stanford.edu">oe@csli.stanford.edu </a>; <a href="mailto:oe@ifi.uio.no">oe@ifi.uio.no</a>; <a href="mailto:stephan@oepen.net">stephan@oepen.net</a> --- +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ </blockquote></div> -- --Eric Nichols
