Hi, I have just manged to get some time to look into the issue and have found what appears to be a problem.
The build compatablity check that is failing, the previous and current DatabaseBuilder having a different number of layer image options, seems to be the correct state when adding a new layer. If I understand this correctly, the check should not be in the code as this will stop you from ever adding new layers to an existing database. I will submit a patch that removes this check but thought I would see if anyone knew if it is there for a reason that I am missing. The relevent code is in BuildOptions.cpp in the compatable method. I have now created a more complex test which is failing in a different way so back to the debugger.. : ) Cheers, Brad -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Christiansen, Brad Sent: Wednesday, 23 June 2010 1:16 PM To: OpenSceneGraph Users Subject: [osg-users] VPB master fails to patch an existing database (serialization error again?) Hi, I seem to have uncovered another issue with the recent changes to VPB. If I try to do a trivial patch of an existing database I get the error: Build configuration invalid : Previous build options not compatible with new build options, cannot patch database. To reproduce the problem I am using the following simple test case: -create the database: vpbmaster --bluemarble-west -t hills.png --bluemarble-east -t hills2.png -o ./out/test.osgb -then patch it: vpbmaster --patch ./out/test.osgb --add --layer 1 --bluemarble-east -t hill3.png This used to work without issue. I have started tracking down what is going wrong and it seems to be failing in BuildOptions.cpp method: bool BuildOptions::compatible(BuildOptions& rhs) const. This method returns false as the number of image options are different ( if (_imageOptions.size() != rhs._imageOptions.size()) return false; ). It seems that when the new .soure file is written out (in the test case above, the file: test.osgb.1.source) it contains two identical ImageOptions. I will keep investigating and post any further information, or hopefully a fix.
