Windows 11 的 WSL(Ubuntu2204) 安裝OpenCV 4.5.4 (親測(cè)有效)

一、WSL 安裝

直接在 Windows Store 里搜索最新的 Ubuntu版本 22.04 版本進(jìn)行安裝；

二、編譯安裝 OpenCV

在 Powershell 里輸入 wsl進(jìn)入環(huán)境，

sudo apt install build-essential
sudo apt install cmake git libgtk2.0-dev pkg-config 
sudo apt install libavcodec-dev libavformat-dev
sudo apt install libjpeg-dev libswscale-dev libtiff5-dev
sudo apt install python-dev python-numpy libtbb2 libtbb-dev libpng-dev libjasper-dev libdc1394-22-dev

無(wú)法安裝 libjasper-dev 和 libdc1394-22-dev

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package libjasper-dev
E: Unable to locate package libdc1394-22-dev

---

解決一：
sudo vim /etc/apt/sources.list
最后一行加入如下內(nèi)容并保存退出：
deb http://security.ubuntu.com/ubuntu xenial-security main

再執(zhí)行：
sudo apt-get update

---

解決二：

sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt update
sudo apt install libjasper1 libjasper-dev

但是可能會(huì)出現(xiàn)問(wèn)題如下：

無(wú)法安裝 libdc1394-22-dev

Reading state information... Done
E: Unable to locate package libdc1394-22-dev

問(wèn)題解答

The libdc1394-22-dev package was removed in Debian and Ubuntu after 21.10. This is because the source package it was from - libdc1394-22 - was superseded by a different package.

The package was orphaned and removed with Debian Bug #963924 because the package libdc1394 has superseded libdc1394-22.

It has its own dev package - libdc1394-dev - which will probably get you what you want/need. So install that package instead of the package you were trying to install.

安裝 libdc1394-dev即可。

sudo apt install libdc1394-dev

（一）下載 OpenCV

進(jìn)入 OpenCV 官網(wǎng) 下載對(duì)應(yīng)版本，我這里用的是 4.5.4;

（二）編譯安裝

將下載的源碼拷貝到 WSL 系統(tǒng)里的 /home 目錄下，并解壓。

cd opencv-4.5.4
mkdir build && cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE \
      -D CMAKE_INSTALL_PREFIX=/usr/local \
      -D OPENCV_GENERATE_PKGCONFIG=ON ..
make -j
sudo make install   # 安裝

可能出現(xiàn)的問(wèn)題1：找不到ippcv

ippcv資源百度盤(pán) 提取碼： 8888

將下載的文件替換到 .cache 目錄下，并將文件名替換為下載的文件名。 重新編譯。

參考： https://blog.csdn.net/qq_43478260/article/details/109458079

可能出現(xiàn)的問(wèn)題2：找不到ade

OpenCV的gapi模塊的編譯依賴ADE，在OpenCV的build過(guò)程中會(huì)自動(dòng)下載ADE，因?yàn)楸粔α?，所以下載失敗，所以要手動(dòng)下載并修改相關(guān)文件；

ade資源百度盤(pán) 提取碼：8888

通過(guò)命令查看ade的md5值，并根據(jù)值修改相關(guān)文件；

md5sum ade.zip

修改文件 DownloadADE.cmake (modules/gapi/cmake/DownloadADE.cmake) 里

set(ade_md5 ... 里面的md5值替換成剛才的值，

修改 "https://github.com/opencv/ade/archive/" 為文件路徑 file///home/usrname/opencv3rd/

ocv_download(FILENAME ${ade_filename}
HASH $ad{e}_{m}d5URL"${OPENCV_ADE_URL}"
“$ENV{OPENCV_ADE_URL}”
“https://github.com/opencv/ade/archive/”
DESTINATION_DIR ${ade_src_dir}
ID ADE
STATUS res
UNPACK RELATIVE_URL)

修改完后，重新編譯。

可能出現(xiàn)的問(wèn)題3：內(nèi)存不足

C++: fatal error: Killed signal terminated program cc1plus的問(wèn)題解決

編譯過(guò)程中，過(guò)度占用了宿主機(jī)的CPU和內(nèi)存，可以減少編譯線程；

make -j4 # 之前是 make -j 需修改為 make -j4, 可能編譯會(huì)慢很多，但是穩(wěn)

（三）環(huán)境變量配置與驗(yàn)證

sudo vim /etc/ld.so.conf

在最后加上一行 /usr/loacal/lib, 完成后 ESC再輸入 :wq保存退出。

運(yùn)行

sudo ldconfig

然后修改 bash.bashrc文件

sudo vim /etc/bash.bashrc

在文件末尾加入：

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

然后進(jìn)行 souce，更新環(huán)境變量

source /etc/bash.bashrc

驗(yàn)證是否安裝成功

pkg-config --modversion opencv4

輸出 4.5.4代表安裝成功。

三、安裝Xserver, 圖形化顯示

在 wsl 里安裝 xfce4

sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install xfce4
sudo apt install xfce4-session

配置環(huán)境變量

在wsl里

sudo vim ~/.bashrc

末尾添加

export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0

使配置生效

source ~/.bashrc

運(yùn)行命令：

startxfce4

遇到如下錯(cuò)誤

xfce4-panel: Failed to connect to session manager: Failed to connect to the session manager: IO error occured opening connection

link

this error occurs with permission issues, try: sudo -u youruser startxfce4

如果要在Windows上查看系統(tǒng)，需要安裝一個(gè)Xserver，可以安裝VcXsrv，鏈接：https://sourceforge.net/projects/vcxsrv/

Windows上啟動(dòng) XLaunch，

Display settings: One large window
How to start clients: Start no client
Disable access control: Yes：

保存完成后，下次直接點(diǎn)開(kāi)保存的文件即可打開(kāi)。

至此已經(jīng)可以在Windows11下可以看到 WSL里的Ubuntu2204系統(tǒng)和文件了。

3. https://blog.csdn.net/Undefinedefity/article/details/106180033

四、驗(yàn)證是否顯示OpenCV

進(jìn)入到OpenCV的samples目錄下

cd ~/opencv-4.5.4/samples/cpp/example_cmake/
cmake .
make 
./opencv_example

至此，終于可以在Windows11的WSL上使用Ubuntu2204愉快的玩耍OpenCV了。

五、其他

1. wsl 使用了Windows里的環(huán)境變量，想要去掉

在 /etc/wsl.conf 里插入如下代碼可以不使用Windows的環(huán)境變量：

[interop]
appendWindowsPath = false

echo $PATH 可以查看環(huán)境變量是否已經(jīng)發(fā)生了變化；

如果wsl要重新啟用Windows的環(huán)境變量，那么就刪除該段代碼

https://learn.microsoft.com/en-us/windows/wsl/wsl-config#configure-per-distro-launch-settings-with-wslconf

2. 重啟 WSL

右鍵 Powershell 管理員身份打開(kāi)，輸入下面命令

#停止LxssManager服務(wù)
net stop LxssManager  
 
#啟動(dòng)LxssManager服務(wù)
net start LxssManager
