Thanks for your interest in the Intel® Realsense™ Platform.
Could you be so kind to tell me which repository are referring to? It will be helpful in order to help us find a solution to your issue.
We will be waiting for your reply, have a nice day!
I'm talking about the files under the "examples" folder. Here is the link, https://github.com/IntelRealSense/librealsense
Sorry I didn't leave much detail. I'm actually a graduate student in mechanical engineering. I got the camera yesterday and it confuses me a lot, but it's actually my bad.
Thank you for your reply. Actually I read this before and I think I imported the workspace into the QTcreator
But when I try to build this tutorial-1-depth, it gives the error " no rule to make target "all", stop", and I'm not sure how to proceed from here.
Also, I wonder if you are familiar with ROS? If I may, could I ask you a few more questions?
Some people who have had this error fixed it by going to the Projects tab in QT Creator and un-ticking the 'Shadow' option in the build settings.
Others have found that a project name that is too long (more than 50 characters) or using exotic language symbols such as Greek can cause it. Since you are building a sample though that already has an acceptable project name, I would try un-ticking Shadow first.
