解决方法：

复制代码

1.vim /etc/apt/sources.list

2.根据自己的操作系统版本添加对应的源
如果是ubuntu20 最后一行添加
deb http://archive.ubuntu.com/ubuntu focal-updates main


如果是ubuntu22,最后一行添加
deb http://archive.ubuntu.com/ubuntu jammy-updates main

3.跟新 sudo apt update
4.重新安装 sudo apt install libgtk-3-dev

3.编译

复制代码

cd SIBR_viewers
cmake -Bbuild . -DCMAKE_BUILD_TYPE=Release # add -G Ninja to build faster
cmake --build build -j24 --target install

4.安装完后，启动程序

安装目录在 SIBR/install/bin
