From Ulrich Hertlien, "'m was getting a build failure from the OpenEXR reader on Mac OS X. It was complaining about undefined references to half::convert(int). I believe this is because the EXR plugin doesn't explicitly link against the Half library. Attached is a modified FindOpenEXR.cmake module that locates IlmIlf and Half, as well as a modified exr/CMakeLists.txt that picks up this change. Also attached are some typo fixes for CMakeModules. Cheers,"

From Laurens Voerman, I have modified the FindOpenEXR.cmake to find the debug libraries, and to define a variable (OPENEXR_LIBRARIES_VARS) with the variable names that might have a _DEBUG version defined. git-svn-id: http://svn.openscenegraph.org/osg/OpenSceneGraph/trunk@14830 16af8721-9629-0410-8352-f15c8da7e697

From Laurens Voerman, "attached is a zip with the files: OpenSceneGraph\CMakeModules\FindOpenEXR.cmake I introduced a bug in the previous submission pointed out by Dmitry Marakasov: looking for IlmIlf instead of IlmImf (as the previous version did - but using variable OPENEXR_IlmIlf_LIBRARY) For some reason google decided his message was spam, so I just noticed it, and I reply to confirm his remarks and attach a full file.

attached fixes for configuring and building the osgPlugin exr with Visual Studio and using out-of-the-box builds of ilmbase and openexr, i.e. without manual/extra config for using these 2 libs with the OSG. Previously, the assumption was made that ilmbase and openexr were installed in a common directory and hence the header files and libs were both found in that common directory. That is not consistent with other libs and this submission makes it consistent and therefore the OSG configures out of the box. I made this work for ilmbase-2.1.0.tar.gz / openexr-2.1.0.tar.gz and ilmbase-2.2.0.tar.gz / openexr-2.2.0.tar.gz

From Simon Julier, "I ran across linking errors with osgdb_exr. Specifically, I found it was necessary to link against libImlIlf, libImlThread, libHalf, libIex and libzip. I have attached a patch, against the trunk from 13:30 today, which consists of the following: 1. CMakeModules/FindOpenEXR.cmake: Look for libIlmThread and libIex as well. 2. src/osgPlugins/CMakeList.txt: Only include the exr subdirectory if both the OpenEXR and zip libraries were found. 3. src/osgPlugins/exr/CMakeLists.txt: Add ZIP_LIBRARY to TARGET_EXTERNAL_LIBRARIES."
