Hi Greg,

The GDAL extensions are available for both v90 and v100.  Basically we match the extensions to the build we are using.  If we have a v90 GDAL dll, then we would use v90 extensions.  If we move to a v100 GDAL dll then we would match it with v100 extensions.

If possible, it would be good to maintain a v90/v100 match between FDO and MapGuide.  There may be no issues using a v90 FDO with a v100 MapGuide.  I simply do not know.  In the past, we have always been in sync.  MapGuide and FDO do share the same process space so there is potential for unexpected behaviour.

Regards,
Trevor

Hi Trevor,

I agree that v100 versions of the GDAL binaries are available. However, we would need to port the FDO API, and its dependencies to v100. That would could ripple through the other providers, many of whom do not have v100 native SDKs available. While the OSGeo community is still discussing the matter, we have not yet decided to move FDO to v100. 

As for mixing runtimes for GDAL Provider and the GDAL extensions, (not being sure of how MapGuide is setup) who would be loading a v100 version of the GDAL extensions and in what content?

Greg

Hi Greg,

Mixing VC7 and VC9 binaries for the GDAL extensions caused the GDAL Provider to crash.  Using VC9 binaries for the extensions resolved the issue.

Prebuild GDAL binaries for VC2010 are available on http://vbkto.dyndns.org/sdk/.  It might be easier to use them directly.

Binaries for various flavours of linux are also listed on the website although I do not see RHEL 5 covered http://trac.osgeo.org/gdal/wiki/DownloadingGdalBinaries


Regards, 
Trevor

The OSGeo FDO project has no plans to port the GDAL Provider to the v100 runtime. 

What problems did you see and how are they related to the mixing of v90 and v100 runtimes?

Regards,
Greg

Hello Mars,

We should only move MapGuide to Visual Studio 2010 if FDO is also moving to Visual Studio 2010.  I have seen unusual application behaviour with the FDO GDAL Provider in MapGuide when mismatched dlls are used.

Regards,
Trevor

Hi all,

I'd like to get your feedback about moving MapGuide to VS2010, both project files and compiler.

Bruce has posted a RFC last year about moving MapGuide to VS2010 project while keeping the code compiled with VS2008 compiler. http://trac.osgeo.org/mapguide/wiki/MapGuideRfc104
This RFC was adopted but not yet completely implemented. Now a year has passed maybe we could move one step further to move MapGuide to also VS2010 compiler.

As the first step, we might keep the source code still compile with VS2008 and do some porting to make it also compile with VS2010 compiler. (The VS2008 project files are still available).

Could you share your feedback and concerns for this move? Is there any risk from your point of view (e.g. we already know some 3rd party components don't have VC10 built binaries)?

Thanks,
Mars
