Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libgtk-3-dev : Depends: libatk-bridge2.0-dev but it is not going to be installed Depends: libatk1.0-dev (>= 2.15.1) but it is not going to be installed Depends: libcairo2-dev (>= 1.14.0) but it is not going to be installed Depends: libfontconfig1-dev but it is not going to be installed Depends: libgdk-pixbuf2.0-dev (>= 2.40.0) but it is not going to be installed Depends: libglib2.0-dev (>= 2.57.2) but it is not going to be installed Depends: libpango1.0-dev (>= 1.41) but it is not going to be installed Depends: libxi-dev but it is not going to be installed Depends: libgtk-3-0 (= 3.24.20-0ubuntu1) but 3.24.20-1 is to be installed E: Unable to correct problems, you have held broken packages.
解决方法：
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-dev3.编译
cd SIBR_viewers
cmake -Bbuild . -DCMAKE_BUILD_TYPE=Release # add -G Ninja to build faster
cmake --build build -j24 --target install4.安装完后，启动程序
安装目录在 SIBR/install/bin
