arm视频linux与udev的交叉编译

Architecture:          aarch64
Byte Order:            Little Endian
Model name:            ARMv8 Processor rev 3 (v8l)

为此,我安装了必要的交叉编译器

sudo apt-get install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu

由于我们使用Qt,因此我还为这个特定的体系结构交叉编译了Qt:

./configure -xplatform linux-aarch64-gnu-g++ -opensource \
  -confirm-license -nomake tests -nomake examples -static \
  -skip qtwebengine -release -prefix /opt/qt5-arm -no-xcb \
  -no-opengl -no-use-gold-linker

aarch64-linux-gnu-g++  -o bin/executable <removed unimportant stuff>... 
   -lv4l2 -lv4lconvert -L/opt/qt5-arm/plugins/imageformats -lqgif 
   -L/opt/qt5-arm/lib -lqicns -lqico -lqjpeg -lQt5DBus 
   -lQt5Gui -lqtlibpng -lqtharfbuzz -lQt5Network -lQt5Core 
   -lm -lqtpcre2 -ldl -lpthread 

由于我没有交叉编译linux视频,因此我收到了以下错误消息:

/usr/bin/aarch64-linux-gnu-ld: cannot find -lv4l2
/usr/bin/aarch64-linux-gnu-ld: cannot find -lv4lconvert
collect2: error: ld returned 1 exit status

问题来了:

我从哪里获得video4linux的源代码,如何为我的架构交叉编译它们?请注意,我从 https://www.linuxtv.org/downloads/

2. 我不认为这是我需要的:)
