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...

option on Linux.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2>Hello Traian,</FONT></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. </FONT></DIV>

<DIV><FONT face=Arial size=2>My FC4 setup is pretty much straight out of the box
except for the upgrade to gcc 4.0.2. pgsql is 8.1.2, postgis 1.1.1, gdal
1.3.2, geos2.2.2, and all are installed in default locations
(e.g. /usr/local for everything). I'm stumped on this one.....</FONT></DIV>

trying to load a provider but failing. It can happen either because of
missing dependencies (which you don't seem to have), mismatched provider

"CreateConnection()" in the provider .so. I can't think of another reason it
won't load, but I will try compiling it on FC4 and see if it works for
me.</FONT></SPAN></DIV>

also fix the Windows-style newlines :-), and then use the SetResource page
to upload it to the server. You will need to set the Content field in the
SetResource page to that file. After executing the SetResource, you should be
able to see this feature source in Studio and create a layer based on it. When
you point the new layer to this feature source, it will either succeed or show
an error. If it shows an error, it would be a good time to check the log
again. Also, if possible, run the server from the command prompt and watch if
it prints out any errors or warnings.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2></FONT> </DIV>
<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></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 if it
is related or not, but if anybody has seen this and knows how to fix 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>
