[Pipet Devel] Big request from everyone

Happy to be of service!

Great! Thanks much for trying this out!

XDBM is a library that provides an XML database functionality. It can take
XML files and then convert them into 'XDBM format' which is a preparsed
format. It then provides functions for searching this format which will be
(hopefully) much faster than the standard python DOM stuff. XDBM will
hopefully soon have a python binding which will allow a DOM and SAX
interface to the library. The plan is that XDBM will do all of the xml
storage manipulation for Loci.

>Does anyone (Brad !!!) has a test script or something similar ?

Right, I checked into this and got the following. At the end of this mail
are three C programs that will test different functions of XDBM. According
to the docs, you need to link against libxdbm, libunicode, libpcre, and
libXpat when compiling the tests. Of course, since I haven't got it working
yet, I can't offer any other advice, but it seems like you are waaaay ahead
of me...

I hope so! I'm really stuck for something to try next. After the changes I
made that I detailed in my last e-mail, I can compile up until the utils
directory, when I get the following:

gmake[1]: Entering directory `/usr/local/libxdbm-1.0.5/utils'
#gcc295 -g -pg -static -L../../lib -L../lib  xml2xdbm.o -o xml2xdbm -lxdbm
-lunicode -lXpat -lm
gcc295 -L../../lib -L../lib  xml2xdbm.o -o xml2xdbm -lxdbm -lunicode -lXpat
-lpcre -lm
../../lib/libXpat.so: undefined reference to `stderr'
../../lib/libunicode.so: undefined reference to `towlower'
../../lib/libXpat.so: undefined reference to `__fxstat'
collect2: ld returned 1 exit status

I'm not positive why I'm not finding these functions. Not being experienced
at all with C programming/porting, I'm not positive where to turn next. Any
advice you could offer would be *greatly* appreciated!

Thanks again for testing this out for me. Below is the C code and the xml
file they work on.
