環境 |
|
|---|---|
| OS | ubuntu 16.04 |
| kernel | 4.10.0-28-generic |
| camera | Creative VF0800(F200) |
| librealsense | v1.12.1 |
1. Ensure apt-get is up to date
OSをアップデートする。
sudo apt-get update && sudo apt-get upgrade
Note: Use sudo apt-get dist-upgrade, instead of sudo apt-get upgrade, in case you have an older Ubuntu
14.04 version (with deprecated nvidia-331* packages installed), as this prevents the linux 4.4* kernel to compile properly.
2. librealsense v1.12.1をgit cloneする。
git clone -b v1.12.1 https://github.com/IntelRealSense/librealsense.git
3. Install libusb-1.0 and pkg-config via apt-get
libusbをapt-getでインストールする。
sudo apt-get install libusb-1.0-0-dev pkg-config
4. glfw3をインストールする。
For 16.04 you can install glfw3 via sudo apt-get install libglfw3-dev
GTK+3.0 install
sudo apt-get install libgtk-3-dev
5. We use QtCreator as an IDE for Linux development on Ubuntu qt_creater
qt_createrでlibrealsenseをbuildしたい場合はqt_createrをインストールする。
Note: QtCreator is presently configured to use the V4L2 backend by default
sudo apt-get install qtcreator
sudo scripts/install_qt.sh (we also need qmake from the full qt5 distribution)
all.pro contains librealsense and all example applications
From the QtCreator top menu: Clean => Run QMake => Build
Built QtCreator projects will be placed into ./bin/debug or ./bin/release
6. We also provide a cmake file if you'd prefer to use your own favourite text editor
QtCreaterを使わない場合はこっち。
mkdir build
cd build
cmake ..
make && sudo make install
The library will be installed in /usr/local/lib and header files in /usr/local/include.
Note: If you would also like to compile the code examples use:
cmake .. -DBUILD_EXAMPLES:BOOL=true
make && sudo make install
The example executables will build into ./examples and install into /usr/local/bin.
Video4Linux backend
ubuntu 16.04(kernel 4.10)ではこの作業は必要なし。
Video4Linuxの設定
Ensure no cameras are presently plugged into the system.
Install udev rules
** git cloneしたディレクトからudev rulesをコピーする。
sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/
rouleのreload
sudo udevadm control --reload-rules
USB コネクタを抜き差しする代わりにudevadm triggerを実行
udevadm trigger
Next, choose one of the following subheadings based on desired machine configuration / kernel version (and remember to complete step 4 after).
*Note: * Multi-camera support is currently NOT supported on 3.19.xx kernels. Please update to 4.4 stable.
Ubuntu 14.04.[0-4]
Update to 4.4 Stable Kernel
Run the following script to install necessary dependencies (GCC 4.9 compiler and openssl) and update kernel to v4.4-wily
./scripts/install_dependencies-4.4.sh
Run the following script to patch uvcvideo.ko
./scripts/patch-uvcvideo-4.4.sh v4.4-wily (note the argument provided to this version of the script)
This script involves shallow cloning the Linux source repository (~100mb), and may take a while
(OR) Keep 3.19.xx Kernel
Run the following script to patch uvcvideo.ko
./scripts/patch-uvcvideo-ubuntu-mainline.sh
(R200 Only with 3.19.xx Kernel) Install connectivity workaround. Note this script needs to be run from within the scripts folder:
cd scripts
./install-r200-udev-fix.sh
cd ..
This udev fix is not necessary for kernels >= 4.2
Use of 3.19.xx Kernel is not recommended.
(OR) Ubuntu 14.04.5 or Ubuntu 16.04.xx (Kernel 4.4)
今回はubuntu 14.0.5なのでこれを実行
sudo apt-get install libssl-dev
uvcvideoにpatchをあてます。
./scripts/patch-uvcvideo-16.04.simple.sh
(OR) Arch based distributions
You need to install the base-devel and linux-headers package group.
Then run the following script to patch the uvc module:
./scripts/patch-arch.sh
Reload the uvcvideo driver
ubuntu 16.04(kernel 4.10)ではこの作業は必要なし。
uvcvideoドライバーをリロースする。
sudo modprobe uvcvideo
Check installation by examining the last 50 lines of the dmesg log:
カーネルメッセージを確認する。
sudo dmesg | tail -n 50
The log should indicate that a new uvcvideo driver has been registered. If any errors have been noted, first attempt the patching process again, and then file an issue if not successful on the second attempt (and make sure to copy the specific error in dmesg).
動作確認
./build/examples/cpp-enumerate-devicesを実行してF200がみつかればOK
