Hi, Thanks for the suggestions. I made the changes you recomened but it seems to have had no effect on my problems. When I tried rebuilding after the change I got the following results:
OpenThreads, Builds fine. osg, Builds fine. osgUtil: 60 warnings about duplicate symbols from OpenThreads osgText (which built osgDB first): 2126 warnings about duplicate symbols from both OpenThreads and osg. Some examples: osg35-osg.lib(VertexProgram.obj) : warning LNK4006: "public: static void __cdecl osg::VertexProgram::discardDeletedVertexProgramObjects(unsigned int)" ([EMAIL PROTECTED]@osg@@[EMAIL PROTECTED]) already defined in osg35-osgDB.lib(VertexProgram.obj); second definition ignored osg35-osg.lib(WIN32Condition.obj) : warning LNK4006: "public: virtual int __thiscall OpenThreads::Condition::wait(class OpenThreads::Mutex *,unsigned long)" ([EMAIL PROTECTED]@OpenThreads@@[EMAIL PROTECTED]@[EMAIL PROTECTED]) already defined in osg35-osgDB.lib(WIN32Condition.obj); second definition ignored The drails of what I did are: I modified the files as suggested (in 16 files, I am not building any plugins / applications or the wrappers). I reconfigured the static project using cmake. I checked the preprocessor definintions in Visual Studios. Osg, osgUtil, osgDB and osgText all had OSG_LIBRARY_STATIC OT_LIBRARY_STATIC defined. Any further suggestions would be very welcome.

A quick and dirty fiy would be: change CMakeLists for all osg-libs/src from IF (DYNAMIC_OPENSCENEGRAPH) ADD_DEFINITIONS(-DOSG_LIBRARY) ELSE (DYNAMIC_OPENSCENEGRAPH) ADD_DEFINITIONS(-DOSG_LIBRARY_STATIC) ENDIF(DYNAMIC_OPENSCENEGRAPH) to IF (DYNAMIC_OPENSCENEGRAPH) ADD_DEFINITIONS(-DOSG_LIBRARY) ELSE (DYNAMIC_OPENSCENEGRAPH) ADD_DEFINITIONS(-DOSG_LIBRARY_STATIC) ADD_DEFINITIONS(-DOT_LIBRARY_STATIC) ENDIF(DYNAMIC_OPENSCENEGRAPH) The underlying problem is: The setting, that you compiled OpenThreads statically is not carried out to a public header or something. If another lib includes a header-file of OpenThreads the compiler thinks, that OpenThreads is linked for dynamic-usage (because OT_LIBARY_STATIC is not defined so the EXPORT-definition for OpenThreads is not setup correctly), so you'll get multiple defined symbols, when you try to link your app with static OpenThreads and static osg, because osg includes OpenThreads-symbols for dynamic-linking. IMHO the definition of OT_LIBARY_STATIC should be carried out to OpenThreads/Config. The same should be done for OSG_LIBRARY_STATIC. On Linux there's no such problem, because you don't have to declare different exports for static versus dynamic linking. I am no expert in CMake, so perhaps somebody may jump in here? cheers, Stephan _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g DISCLAIMER:--------------------------------------------------------------------------- This e-mail transmission and any documents, files and previous e-mail messages attached to it are private and confidential.
