Ubuntu14.04 Installing Librealsense (camera R200)

Before the initial installation, a lot of information was checked. Later found that the official website is the most reliable documents.

Refer to the '/doc/installation.md' note on GitHub:

Now the Librealsense Master branch on GitHub is the 2.0 version of the SDK, my webcam is R200, the recommended installation should be version 1.0, under Legacy Branch. This need to pay extra attention, I just because I did not pay attention to read instructions, came up on the Mater Branch under the 2.0, the results can not open my R200. A issue, only to know that the pack 1.0

installation process: to upgrade the Ubuntu14.04 kernel, make sure that you are at least 4.4.50

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

For some low-version kernels, the above three commands are not sufficient to ensure that the kernel can be successfully upgraded and then run:

sudo apt-get install--install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial Xserver-xorg-lts-xenial xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial Libwayland-egl1-mesa-lts-xenial

Remember the version of the kernel that was installed, such as the one I installed here is 4.4.0-112-generic (this step was done once during the installation of version 2.0, then upgraded to 4.4.0-111-generic) and then restarted.

sudo update-grub && sudo reboot

Select the advanced option when restarting, choose 4.4.0-112-generic to run after the boot entry system

Uname-r

Confirm the kernel version
Install dependencies

sudo apt-get install Libusb-1.0-0-dev pkg-config

Download the files under the Legacy branch and unzip the folder directory into the extracted folders. ` ~/downloads/librealsense-legacy/`

./scripts/install_glfw3.sh

Connect the camera and run the Cpp-capture in the/usr/local/bin/directory.

The installation was successful.

Note:

The first installation error, Ann became SDK2.0, later Loaded 1.0, but did not put 2.0 first uninstall, or a little problem.

Go to the 2.0SDK folder under the Build folder and run

sudo make uninstall make clean

Clean up the front, and then it's all right.
