BSDI? Why didn't you say so? :) This is a known problem, which was
discussed again this morning. In response to this, I've added this to
the FAQ, which should appear on the www.htdig.org web site soon:
5.14. I get Segmentation faults when running htsearch or htfuzzy.
Despite a great deal of debugging of these programs, we haven't been
able to completely eliminate all such problems on all platforms. If
you're running htsearch or htfuzzy on a BSDI system, a common cause of
core dumps is due to a conflict between the GNU regex code bundled in
htdig 3.1.2 and later, and the BSD C or C++ library. The solution is to
use the BSD library's own regex code instead, as summarized by Joe Jah:
. make clean
. Remove references to regex.o from htlib/Makefile.
. Remove htlib/regex.h.
. Remove references to htlib/regex.h in htfuzzy/Makefile, which
will be there if you have previously done a "make depend".
. make
..
I think this should do the trick for you.
Cheers!
