Solved: Error compiling ofxKinect example

beginners
#1

I am trying to use the ofxKinect library with OF but I can’t get the example to compile.
I using Ubuntu 10.04, Codeblocks 8.02, OpenFrameworks 0.062 and the latest version ofxKinect from the github ‘master’ branch.

Any help would be appreciated. I’m sure it’s a simple fault on my part (I’m new to OpenFrameworks and C++).

The output from the debugger is below…

Ok, solved my own problem. Just needed to add the files to Codeblocks.

Now I’m getting an error about a missing library:

  
error while loading shared libraries: libfmodex.so: cannot open shared object file: No such file or directory

I checked the libs/fmodex folder in OpenFrameworks and the library appears to be there. Gonna keep trying but any help would be appreciated.

Also, should I open a new post for a new question? Thanks in advance for any help.

OK, fixed that as well and got it to compile. The library needed copying to /usr/lib/ .
