Re: [osg-users] First recipe from cookbook won't compile with given source code
Thank you, Julien. Though there are two different CMakeLists.txt files (https://github.com/xarray/osgRecipes/CMakeLists.txt and https://github.com/xarray/osgRecipes/tree/master/cookbook/CMakeLists.txt), I tried with the first one, because you said so. I had to give a value to the OPENSCENEGRAPH_LIB_DIR (/usr/local/lib64) in CMake, but it still gives me an error: > Could NOT find OpenCV (missing: OpenCV_ROOT_DIR OpenCV_LIBRARIES_RELEASE > OpenCV_LIBRARIES_DEBUG OpenCV_LIBRARIES) > Could NOT find ALVAR (missing: ALVAR_ROOT_DIR ALVAR_INCLUDE_DIRS > ALVAR_LIBRARIES_RELEASE ALVAR_LIBRARIES_DEBUG ALVAR_LIBRARIES) > CMake Error: The following variables are used in this project, but they are > set to NOTFOUND. > Please set them or make sure they are set and tested correctly in the CMake > files: > GLEW_LIBRARY > linked by target "osgnanovg" in directory > /home/rodrigo/Videos/osg/rodrigo/osgRecipes-master/integrations/osgnanovg > > Configuring incomplete, errors occurred! > See also > "/home/rodrigo/Videos/osg/rodrigo/osgRecipes-build/CMakeFiles/CMakeOutput.log". > See also > "/home/rodrigo/Videos/osg/rodrigo/osgRecipes-build/CMakeFiles/CMakeError.log". > And with this I cannot "make" or "make install" it. The readme gives an even more incomplete direction (say nothing about the OPENSCENEGRAPH_LIB_DIR variable, and why not use the default set by OSG?). Going the way I was going, I managed to compile and run most of the recipes in chapter 2. I wouldn't mind giving up one recipe or another just because I didn't install some obscure library. So, maybe using g++ is an easier option? (This includes me losing years with Borland Delphi, instead of learning and dominating C++ and CMake stuff.

[osg-users] First recipe from cookbook won't compile with given source code
Hi, I'm following the OpenSceneGraph 3 Cookbook (http://ahux.narod.ru/olderfiles/1/OSG3_Cookbook.pdf) to learn more about OSG. So I created a directory Cookbook following the directory structure from the source code here (https://github.com/xarray/osgRecipes/tree/master/cookbook). Before compiling the first recipe, I had copied the "Common Functions" from the textbook (pages 38-39), into a file called "CommonFunctions". When compiling (with g++ on Linux) I got the following error: > $ g++ observer_ptr.cpp -I../.. -losg -losgDB -losgGA -losgText -losgUtil > -losgViewer -o observer_ptr > > In file included from observer_ptr.cpp:11:0: > ../../CommonFunctions: In member function ‘virtual bool > osgCookBook::PickHandler::handle(const osgGA::GUIEventAdapter&, > osgGA::GUIActionAdapter&)’: > ../../CommonFunctions:47:62: error: binding ‘const > osgUtil::LineSegmentIntersector::Intersection’ to reference of type > ‘osgUtil::LineSegmentIntersector::Intersection&’ discards qualifiers > osgUtil::LineSegmentIntersector::Intersection& result = > *(intersector->getIntersections().begin()); > ../.. is the path to the CommonFunctions file. I tried a few const_cast operations, but I don't have so much experience with C++ and couldn't solve it. I commented out this two lines and the program compiled fine and ran, though clicking on the objects wouldn't dismiss them (guess that's what these lines do). Then I noticed they have this "CommonFunctions" file together with the given source code, so I replaced mine with theirs (CommonFunctions and CommonFunctions.cpp). But when compiling, a new error: > $ g++ observer_ptr.cpp -I../.. -losg -losgDB -losgGA -losgText -losgUtil > -losgViewer -o observer_ptr > > /tmp/cca0xsAB.o: In function `main': > observer_ptr.cpp:(.text+0x79): undefined reference to > `osgCookBook::createText(osg::Vec3f const&, std::__cxx11::basic_string std::char_traits, std::allocator > const&, float)' > observer_ptr.cpp:(.text+0x103): undefined reference to > `osgCookBook::createHUDCamera(double, double, double, double)' > /tmp/cca0xsAB.o:(.data.rel.ro._ZTV18RemoveShapeHandler[_ZTV18RemoveShapeHandler]+0xb8): > undefined reference to > `osgCookBook::PickHandler::handle(osgGA::GUIEventAdapter const&, > osgGA::GUIActionAdapter&)' > /tmp/cca0xsAB.o:(.data.rel.ro._ZTC18RemoveShapeHandler0_N11osgCookBook11PickHandlerE[_ZTV18RemoveShapeHandler]+0x18): > undefined reference to `typeinfo for osgCookBook::PickHandler' > /tmp/cca0xsAB.o:(.data.rel.ro._ZTC18RemoveShapeHandler0_N11osgCookBook11PickHandlerE[_ZTV18RemoveShapeHandler]+0xb8): > undefined reference to > `osgCookBook::PickHandler::handle(osgGA::GUIEventAdapter const&, > osgGA::GUIActionAdapter&)' > /tmp/cca0xsAB.o:(.data.rel.ro._ZTC18RemoveShapeHandler0_N11osgCookBook11PickHandlerE[_ZTV18RemoveShapeHandler]+0xe0): > undefined reference to `typeinfo for osgCookBook::PickHandler' > /tmp/cca0xsAB.o:(.data.rel.ro._ZTC18RemoveShapeHandler0_N11osgCookBook11PickHandlerE[_ZTV18RemoveShapeHandler]+0x218): > undefined reference to `typeinfo for osgCookBook::PickHandler' > /tmp/cca0xsAB.o:(.data.rel.ro._ZTC18RemoveShapeHandler0_N11osgCookBook11PickHandlerE[_ZTV18RemoveShapeHandler]+0x428): > undefined reference to `typeinfo for osgCookBook::PickHandler' > /tmp/cca0xsAB.o:(.data.rel.ro._ZTI18RemoveShapeHandler[_ZTI18RemoveShapeHandler]+0x10): > undefined reference to `typeinfo for osgCookBook::PickHandler' > collect2: error: ld returned 1 exit status > Can anybody please tell me what am I doing wrong?
