<DIV><FONT face=Arial size=2>Indeed it is a tricky one. I though I had read that
mapguide was using slightly modified versions of gdal and geos? Otherwise I
would have gone ahead and deleted the earlier versions from mg source tree. At
this point I don't have anything to lose by giving it a go. I'll let you know if
I sort this out. In the meantime if you have any other ideas please post them. I
would really like to get mapguide talking to our database.</FONT></DIV>

color=#0000ff size=2>Yeah this one is difficult. For what it's worth, I would
have gone the other way around when moving libraries: any library that is
already installed in /usr/local, I would have simply deleted from the mapguide
directory (things like xerces, libACE, gdal, etc). Come to think of it,
MapGuide builds against a copy of gdal 1.3.0 while the provider was written
against gdal 1.3.2 and uses function calls that don't exist in 1.3.0. So
if it's picking up the wrong gdal at runtime, it will definitely not work.
Ouch... </FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks for all your help. So far no joy. I
manually created the datasource as per your instructions. After starting
Studio, the new resource shows, but when trying to create a layer based on the
new data source, I just get the same error as before.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>One thing I noticed is that mgserver was
segfaulting on exit. Should have noticed it before, but my eyes aren't so good
after years in front of computer screens! I ran mgerver in gdb, let it
segfault and ran a backtrace. The odd thing was that the mgserver was loading
geos from /usr/local/lib instead of /usr/local/mapguideopensoure/lib. I
reconfigured mapguide and saw that although the configure script was looking
for gdal in /usr/local/mapguideopensoure/lib it was grabbing geos from
/usr/local/lib. I moved my copy of geos to another folder and re-ran config.
This time it couldn't find geos at all. After some messing around it compiled
OK using the geos included with mgos. Ran the server and it still segfaulted
on exit. Back to the drawing board and configured without geos support. After
that no more segfault, but still the same problem with the OGR provider.

should be able to see this feature source in Studio and create a layer based

succeed or show an error. If it shows an error, it would be a good time to

<DIV><FONT face=Arial size=2>Thank you for your help. Yes, the compilation
went fine for both the MGOS software and relevant components. I had some
problems with the mgserver hanging, as well as the "make check" step for
compiling the debug profile. Fixed that by upgrading gcc to 4.0.2. My entry
in providers.xml is:</FONT></DIV>

<DIV><FONT face=Arial size=2>Shape and SDF providers are working fine, but
unfornately they are of no use to me. I checked the server error log and
there were some messages about FDO. The funny things is that these messages
showed up in the log yesterday morning. I have been messing about constantly
since then and no more error mesages of any kind have been written to the
log since that time. I even changed the name of libOGRProvider.so in
providers.xml hoping to force an error of some kind just to see if there was
any attempt by the server to actually load the .so file. Here is the message
I found in the log:</FONT></DIV>

<DIV><FONT face=Arial size=2>This is the only error in the log, but is
repeated a number of time. Ran ldd - r on libOGRProvider.so and it looks ok,
output is below. One other strange thing, that is a little off-topic, is
that apache is now spitting a dummy when I try to shut it down with
apachectl --stop. It throws this error:</FONT></DIV>

<DIV><FONT face=Arial size=2>The only thing listening to 8008 is apache, so
I don't get this one at all. All was well until I upgraded gcc. Don't know

it, please let me know.</FONT></DIV>

compiled and installed the provider successfully (by adding an entry to
providers.xml), since you get a Data Connection page for it in Studio. One
thing I would check is whether the libOGRProvider.so has missing
dependencies (by running ldd -r on it). Also check the MapGuide server
error log for any Fdo exceptions -- there should be a message if it can't
even create a connection to OGR. If you run the server from a command line
(using /interactive), you will also be able to see the exceptions printed
on the console (the OGR provider may also print some debug
information to the console that you won't see in the logs). Also make sure
the FDO version listed in providers.xml entry for OGR matches the versions
listed for the other providers (there are some overzealous version checks
in the 1.0 code).</FONT></SPAN></DIV>
