[osg-users] Build From Source question
Hi, I've been using osg so far from the pre-built binaries. But I decided to build from source and had a few queries along the way: When I built the solution in VisualStudio 2005: 4 libraries got built (forgive any typos): osgd, osgAnimationd, osgUtild and OpenThreadsd. After that I started getting a bunch of 1104 Linker errors as it could not find a certain .lib file. My question is that aren't the projects being built sequentially so that the libs required for one project are already built by the project before it ? (as it tries to search for the .lib in additional dependencies) So is it recommended to build each project individually rather than Build Solution ? Or am I doing something wrong here ?

Re: [osg-users] Build From Source question
Hi, I Guess you have run Cmake and located the necessary libs to run OSG, png, jpeg, etc... Usually cmake-gui will highlight these in red on the output windows if they have problem. Also it could be the 3rd party libs you are linking with, mixing 32bit and 64bit or different VS versions, compiler options.. But that said I have not compiled OSG with VS2005 in a while so it could be the build, not sure how many people are still using vs2005. Mine is vs2008 and everything is fine. Post the linker errors.

Re: [osg-users] Build From Source question
Hi Sanat, After that I started getting a bunch of 1104 Linker errors as it could not find a certain .lib file. An OSG lib file? If it couldn't find a certain .lib file, it means one of the previous projects failed to build. Look higher in the compile log, you should see which one failed to build and why. In other words, the linker error is a symptom of the problem, but there will be compiler errors when compiling that lib that will give you the root cause. My question is that aren't the projects being built sequentially so that the libs required for one project are already built by the project before it ? (as it tries to search for the .lib in additional dependencies) Yes. CMake generates a solution and projects that will have the dependencies properly set. So is it recommended to build each project individually rather than Build Solution ? No, Visual Studio takes care of that. Build Solution is equivalent to right-clicking on the ALL_BUILD project and selecting Build. ALL_BUILD is a special project that CMake creates that just has everything as a dependency. There are other special targets such as ZERO_CHECK which makes sure your project files are up to date with the CMakeLists.txt files and regenerates them if not, and INSTALL which does ALL_BUILD and then copies the build products to the directory you put in the CMAKE_INSTALL_PREFIX variable in CMake. Or am I doing something wrong here ? Hard to say without knowing the steps you took... You only say "I get this error", but didn't say what you did to get to that point, so it's hard for us to point out errors in that process if we don't know what the process was... Perhaps looking at the OSG web site would help you start out. (PlatformSpecifics/VisualStudio is a good start). http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/VisualStudio Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com 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
Re: [osg-users] Build From Source question
Hi, So I just built each of the projects individually as visual studio was not building them in the required order and once one of them didn't have its dependencies satisfied, all the following ones would fail in Linking. After I built the projects, the examples and plugins I built using Build Solution. I'm sure there might have been a shorter way of doing this but I couldn't think of, so went with this effort.
