Ubuntu源码安装librealsense

1.下载librealsense
https://github.com/IntelRealSense/librealsense/releases/tag/v2.16.5
2.sudo apt-get install git libssl-dev libusb-1.0-0-dev pkg-config libglfw3-dev

3.sudo apt-get install libgtk-3-dev
报错：

The following packages have unmet dependencies:
 libgtk-3-dev : Depends: libgtk-3-0 (= 3.18.9-1ubuntu3) but 3.18.9-1ubuntu3.3 is to be installed

解决方法：
1)在Software Sources中修改配置：
勾选Important security updates (lucid-security)和Recommended updates (lucid-updates)选项
2)执行update操作

sudo apt-get update

3)重新安装：

sudo apt-get install libgtk-3-dev

4.在 librealsense 文件夹下安装Video4Linux视频内核驱动，注意不要插上摄像头。
构建和应用修补内核模块：

sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules && udevadm trigger
./scripts/patch-realsense-ubuntu-lts.sh

Error when execute ./scripts/patch-realsense-ubuntu-lts.sh

Error Description:

Solution:

lsmod | grep videobuf2_core
sudo modprobe -r uvcvideo
lsmod | grep videobuf2_core
./scripts/patch-realsense-ubuntu-lts.sh

提示完成后，插上RealSense，可执行sudo dmesg | tail -n 50查看结果。

5.编译安装

mkdir build && cd build
cmake ../ -DBUILD_EXAMPLES=true
sudo make uninstall && make clean && make -j8 && sudo make install

6.install完成后，目标文件在 /usr/local/bin中。
进入librealsense/build/examples/capture，输入rs-capture测试。
