I think you're right. Although I downloaded the gazebo-7.0.tar sime time ago, gazebo.h says : /// Interface version number #define LIBGAZEBO_VERSION 0x060
So I think I just download a stable 0.7 version. Tanks for you help! -----Ursprüngliche Nachricht----- Von: Gazebo developers <[email protected]> Gesendet: 18.10.07 14:38:02 An: Gazebo developers <[email protected]> Betreff: Re: [PlayerStage-Gazebo] Problem with infra red interface Jonas, I would guess that you are including headers from 0.7.0 but linking against the library from 0.6.0. At this point you should make sure that pkg-config --libs points to ~/local/lib. These errors are because you are linking against a library that doesn't contain the symbols you need. The gz_ir interface was added between 0.6 and 0.7. You will continue to have these issues until the headers match the libraries. To debug, I would not use pkg-config and just include your local install when you compile. On my system I only have static libraries. base/libgazebo/Makefile.am only directs the autoconf to create the static library at compile time. The fact that you were able to find a shared library either means I am misreading this file or you have an older version of the install. Also, don't worry about libgazeboplugin, you aren't going to need it for what you are trying to do.
