What OS are you on? Which version of ROS (Cturtle/Diamondback/Unstable)?

What is the output of `rosdep satisfy ni`?

okay, here's a solution, after trying the above mentioned approaches I still had the same problem but I finally figured it out.

Open System->Administration->Synaptic manager, search libusb and then select libusb-1.0-0-dev, libusb++-0.1-4c2 for installation.

and rerun rosmake ni --rosdep-install. It works perfectly if it doesn't work then for reference I have the following lib-usb* packages installed libhpmud0,libusb-0.1-4,libusb-1.0-0,libusb-dev,libusb-1.0-0-dev, libusb++-0.1-4c2,libusbsr,libftdi1,libusbmuxd1.

Make sure you have these and if you still have a problem then let me know

Best, CV

Thanks bro! I fixed it by running this command: " sudo apt-get install libusb -1.0-0-dev libusb-dev".

It appears libusb is not installed. Try running rosmake --rosdep-install ni and allow it to install any required dependencies.

Actually, I wouldn't say this is fixed. It does raise some issues as there's a bit more to this than it seems at first glance. Two packages are involved on lucid:

libusb-dev (this is pointer to libusb-0.1)
libusb-1.0.0-dev

From nhanndt's experience, it turns out ni won't compile if libusb-dev is not installed, which may quite often be the case on a fresh install.

Which begs the question - does ni need libusb-dev as an rosdep? Is ni even linking with libusb-1.0? Does it need libusb-1.0?

Looking at the CMakeLists.txt in openni_camera - it's pulling in libusb-0.1 into the example binaries. You can take out the usb reference there and still compile as libusb-1.0 is getting pulled in libraries in the openni package.

So probably the usb linking in target_link_libraries in openni_camera/CMakeLists.txt can be dropped and it will resolve the problem for future users. Can this be confirmed (should probably ticket this)?

actually this is true, we tried this last nite on my colleague's desktop and he had the same issue, he had to do an apt-get upgrade and then install libusb-dev which worked fine after that.
