Well that came across a little harsh. I have no doubt that my troubles stem from me doing something incorrectly due to my ignorance (extremely little experience with OSG). So we both agree the problem is my fault, hopefully together we can find the cause? I didn't think my setup was overly complicated and I thought I was staying out of OSG's way. These are the steps I went through to get where I am now... 1.) Downloaded the OSG 2.8.3 source code. 2.) Used the CMake GUI to generate a make file for OSG. 3.) Ran "make" to build the OSG libraries and executables. 4.) Copied the OSG libraries, headers, and executables into a pretty standard ThirdParty directory in my project (that directory's structure was described in my first post). 5.) In my projects CMake I specify where that OSG ThirdParty directory is and I specify that my project depends on OSG (the CMake statements that do this were also in my first post). 6.) Used CMake to generate a make file for my project. 7.) Built my project without error using "make". 8.) Ran my application and OSG said it couldn't find the FLT plugin. 9.) Tried adding OSG's lib directory to LD_LIBRARY_PATH but that just caused my application to crash. I view those steps as being pretty standard and simplistic but clearly I'm doing something wrong. hopefully something sticks out as being obviously incorrect. robertosfield wrote: > > We can only guess what this might be as you explanation of > what you have done doesn't provide enough useful information. > I tried my best to explain everything I thought was relevant. Perhaps I am omitting something because I don't believe it to be useful. If you could tell me what type of information would make it easier for you to figure out where I'm going wrong then I'd be more than happy to give you that information. I'm more than happy to go into extreme detail...I'd even provide you with a simplified version of my codebase if that would help. robertosfield wrote: > > If Paul is correct and you are getting a crash because you've linked > your application to OSG-2.8.3 and then at runtime forcing the loading > of the osgPlugins-2.9.9/osdb_openflight.so > I was very hopeful that was the case but it just doesn't seem to be. I just built my application against OSG 2.9.9 and my LD_LIBRARY_PATH pointed to OSG 2.9.9's lib directory and I still crash. It appears as though this is not the cause of my problem. robertosfield wrote: > > All you should have to do is set the LD_LIBRARY_PATH to path to the > libraries, and let the OSG at runtime append the osgPlugins-version so > that it can find the appropriate plugin. > That is what I think I'm doing. I'm setting LD_LIBRARY_PATH to point to /work/MyApplication/ThirdParty/Linux.x86_64.gcc/OpenSceneGraph-2.9.9/lib/ Of course inside OpenSceneGraph-2.9.9/lib there is an "osgPlugins-2.9.9" directory which contains the OpenFlight plugin. I can only assume that OSG is looking in that directory. robertosfield wrote: > > Now if you aren't finding > the plugins if you use this approach then it suggests that you have > placed the osgPlugins-version directory into the library directory as > it should be. > OSG only says it can't find the plugin when I do NOT set LD_LIBRARY_PATH. When I do set LD_LIBRARY_PATH my application simply crashes, OSG doesn't tell me if it found the plugin or not. Again my osgPlugins directory is in /work/MyApplication/ThirdParty/Linux.x86_64.gcc/OpenSceneGraph-2.9.9/lib/osgPlugins-2.9.9 and I'm setting LD_LIBRARY_PATH to be /work/MyApplication/ThirdParty/Linux.x86_64.gcc/OpenSceneGraph-2.9.9/lib robertosfield wrote: > > Now the OSG does have a proper install script and if > you use it will place all the libraries and plugins in all the correct > directories, perhaps you've bypassed this completely and are copying > stuff around by hand and screwing things up.

I have not run "make install", only "make". I'm hoping to keep OSG on a level that is local to my project (as opposed to a system level). I'd like to take my project's source code and third party dependencies and check them into SVN. Then a developer can checkout that repository to a local directory and build it without having to make any system level changes...everything is kept local to that checkout folder. I have to assume that OSG can function if it isn't placed wherever "make install" places it but since I'm "copying stuff around by hand" I'll run "make install" and try to make sure that I'm mimicking what "make install" does but on a local level. Again thanks for everybody's help, I really appreciate it.[/list] ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=38028#38028 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
