I had (and still) have issues with using this inside of a catkin workspace.

When building against realsense-ros (https://github.com/IntelRealSense/realsense-ros), I get the following error in realsense2_camera:

CMake Error at /lib64/cmake/realsense2/realsense2Config.cmake:11 (message):
  File or directory //include referenced by variable realsense2_INCLUDE_DIR
  does not exist !
Call Stack (most recent call first):
  /lib64/cmake/realsense2/realsense2Config.cmake:33 (set_and_check)
  CMakeLists.txt:44 (find_package)

I resolved this by manually going into /lib64/cmake/realsense2/realsense2Config.cmake and replacing statement setting PACKAGE_PREFIX_DIR to the following:

set(PACKAGE_PREFIX_DIR /usr)

This part of the configuration is set by the following lines:

https://github.com/IntelRealSense/librealsense/blob/5ff27fca5aaeec4736d6bb3bfb958fee82ee198b/CMake/install_config.cmake#L11-L15

Not sure why the PACKAGE_PREFIX_DIR is invalid, would be nice to have this package install cleanly though.

@pingplug Understood, I apologise for my misconception and thank you very much for the info.

@Svanto I can't run realsense-viewer with glfw-wayland.

Is there a technical reason that the package does not allow to use glfw-wayland in place of glfw-x11 as a dependency? I cannot seem to find one. If there is not, may I request that it's added as an alternative?

Thank you very much for your time.

The amazonaws links are broken.

Fails to build for me with unknown pseudo-op: `.lbe10946' and open CFI at the end of file; missing .cfi_endproc directive:

@pingplug Missing 'glu' on depends. Without glu installed, it will not even compile, giving this error: /usr/include/GLFW/glfw3.h:215:13: fatal error: GL/glu.h: No such file or directory

And namcap output shows that it's needed at runtime: librealsense E: Dependency glu detected and not included (libraries ['usr/lib/libGLU.so.1'] needed in files ['usr/bin/rs-trajectory'])

Please add 'glu' to depends.

Hi! I have this installed, and I get the following error message during boot: systemd-udevd[355]: /etc/udev/rules.d/99-realsense-libusb.rules:3 Unknown group 'plugdev', ignoring

Has anyone else experienced this?

Hi! It would be nice if the package had a .desktop file for the realsense-viewer tool. A possible patch is the following:

I currently use this package together with ROS (melodic) and I'm not quite sure if it was the hardware (D435), librealsense, or the realsense ROS-wrapper itself, but most, if not all, of its launch scripts crashed from time to time. Sometimes it helped to change the USB port, however, at some point the scripts always crashed.

[ERROR] [155...686]: An exception has been thrown: get_xu(...). xioctl(UVCIOC_CTRL_QUERY) failed Last Error: Device or resource busy
[FATAL] [155...196]: Failed to load nodelet '/camera/realsense2_camera' of type 'realsense2_camera/RealSenseNodeFactory' to manager 'realsense2_camera_manager'
... and so on ...

The problem could apparently be solved by passing -DFORCE_LIBUVC=true within the PKGBUILDs build() section. I will continue to use and test this configuration, and may report new findings here. What I can say so far is that the scripts start seemingly more reliable, although not every time.
