First of all, according to http://www.cmake.org/HTML/cmake-2.6.html#command_CMP0003 the directory should not be listed in the library name (TARGET_LINK_LIBRARIES) but in a separate LINK_DIRECTORIES directive. But setting cmake_policy(SET CMP0003 OLD) in the top-level CMakeLists.txt makes it use the old behavior, so I could side-step that issue. (though it should probably be fixed sometime, since CMake 2.6 has been out for a while now) The problem in my quote above seems to be caused by (in CMakeModules/OsgMacroUtils.cmake): MACRO(LINK_INTERNAL TRGTNAME) FOREACH(LINKLIB ${ARGN}) IF(MSVC AND OSG_MSVC_VERSIONED_DLL) #when using versioned names, the .dll name differ from .lib name, there is a problem with that: #CMake 2.4.7, at least seem to use PREFIX instead of IMPORT_PREFIX for computing linkage info to use into projects, # so we full path name to specify linkage, this prevent automatic inferencing of dependencies, so we add explicit depemdencies #to library targets used IF(NOT MSVC_IDE) TARGET_LINK_LIBRARIES(${TRGTNAME} optimized "${OUTPUT_LIBDIR}/${LINKLIB}.lib" debug "${OUTPUT_LIBDIR}/${LINKLIB}${CMAKE_DEBUG_POSTFIX}.lib") ELSE(NOT MSVC_IDE) TARGET_LINK_LIBRARIES(${TRGTNAME} optimized "${OUTPUT_LIBDIR}/${LINKLIB}" debug "${OUTPUT_LIBDIR}/${LINKLIB}${CMAKE_DEBUG_POSTFIX}") ENDIF(NOT MSVC_IDE) ADD_DEPENDENCIES(${TRGTNAME} ${LINKLIB}) ELSE(MSVC AND OSG_MSVC_VERSIONED_DLL) TARGET_LINK_LIBRARIES(${TRGTNAME} optimized "${LINKLIB}" debug "${LINKLIB}${CMAKE_DEBUG_POSTFIX}") ENDIF(MSVC AND OSG_MSVC_VERSIONED_DLL) ENDFOREACH(LINKLIB) ENDMACRO(LINK_INTERNAL TRGTNAME) (sorry for my e-mail client wrapping the lines) I don't understand the reason for the ELSE(NOT MSVC_IDE) part (i.e. when it *is* an MSVC IDE). MSVC seems to think it wants to link to an .obj if you don't specify an extension, and that's exactly what the line there does... It does not specify the .lib extension, unlike the line above it. When I remove that (i.e. just use the TARGET_LINK_LIBRARIES line above, with the .lib extensions) it links fine. I wonder, did those lines change recently? I've never had a problem with that before, and I really wonder why those lines exist at all in the first place... Calling our CMake experts? Anyone? :-) J-S -- ______________________________________________________ Jean-Sebastien Guay [EMAIL PROTECTED] http://www.cm-labs.com/ http://whitestar02.webhop.org/ _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
