[Opensg-users] OpenSG 2: Porting to VC12

[Johannes B. <jb...@da...>]

Hello,

 

I'm in the process of porting our application to the MS Visual Studio
2013 (a.k.a. VC12) compiler and have found some minor problems.

 

1. In file opensg\Source\System\Cluster\Window\Base\OSGClusterWindow.cpp
at line 235 I have changed

from

                SFATAL << "Error starting: " << command << std::endl;

to

                SFATAL << "Error starting: " << command.str() <<
std::endl;

 

because I got the following error message:

...\OSGClusterWindow.cpp(235): error C2678: binary '<<' : no operator
found which takes a left-hand operand of type
'std::basic_ostream<char,std::char_traits<char>>' (or there is no
acceptable conversion) 

 

2. The next two issues are relevant only because I switched to VTK 6.1:

 

a) CMakeLists.txt line 735

I changed the line 

from

          OSG_SET(OSG_VTK_LIBS
"vtkCommon;vtkFiltering;vtkGraphics;vtkIO;vtkRendering")

to

          include(${VTK_USE_FILE})

          OSG_SET(OSG_VTK_LIBS "${VTK_LIBRARIES}")

 

b) opensg\Source\Contrib\VTK\OSGVTKPolyDataMapper.cpp line 394

I changed the line 

from

    pMapper->GetInput()->Update();

to

#ifdef OSG_WITH_VTK_6

    pMapper->Update();

#else

    pMapper->GetInput()->Update();

#endif

 

and added a the flag OSG_WITH_VTK_6. I'm not sure if this change is
semantically correct, but at least it compiles fine :-)

 

3. The last issue is not related to the port. I compile and update all
the support libraries independent of OpenSG. Especially, OpenEXR is
compiled  as a dynamic link library in my setup. Therefore the
OPENEXR_DLL flag must be set. However, the OSGConfigurePackages.cmake
forces the OPENEXR_USE_DLL option to be OFF which in turn forces not to
the the OPENEXT_DLL flag. Currently, I change the generated
CMakeCache.txt file, but it would be fine to have at least an option for
the flag.

 

No other problems so far...

 

Best,

Johannes
