Re: [osg-users] Help compiling example program
Hi, I see. I guess I just assumed the libraries and headers were installed with 'apt-get install openscenegraaph' because I wasn't sure what else openscenegraph might comprise... Anyway, I have another problem now. Trying to compile the example program (using g++) gives me lots of undefined reference errors, however I see that my headers have been installed to /usr/include/ and my libraries to /usr/lib. ?

Re: [osg-users] Help compiling example program
Hi James, Yes sorry that is a link for building OSG itself. Although for Windows it tells you to add the paths to your environment... I think it does for Linux as well. Think Robert may have hit the nail on the head with libopenscenergaph-dev, that would make sense why you cannot find any headers or includes...

Hi James, Looks like it's an easy one to answer, so I will give it a go: It looks like the path to OSG is not set correctly or it doesn’t know where to find your include/lib files. The paths to OSG will need to added to your development environment, not sure what you are using.

Re: [osg-users] Help compiling example program
Hello James,
what do you use? Linux or Windows? Did you build osg or did you use the
binaries?
I use Linux and osg from the repository. I don't need any extra setup, because
/usr/lib64/ is in the search path. By the way, I use the gcc-c++.
If I build osg, I export environment variables:
export OSG301_LIB=pathToOSG/lib64
export OSG301_INC=pathToOSG/include
And I use these in cmake:
NCLUDE_DIRECTORIES($ENV{OSG301_INC})
LINK_DIRECTORIES($ENV{OSG301_LIB})
Cheers,
Martin
