我的系统环境是Ubuntu 20.04。我从以下网址下载了最新的源代码qpdfview（截至目前为 0.5 版本）：https://launchpad.net/qpdfview/+download
文件中的安装说明README：
它依赖于 libQtCore、libQtGui。它还依赖于 libQtSvg、libQtSql、libQtDBus、libcups 和 libz（如果启用了 SVG、SQL、D-Bus、CUPS 和 SyncTeX 支持）。它还依赖于 libmagic（如果使用 Qt 版本 4 并且启用了 libmagic 支持）。PDF 插件依赖于 libQtCore、libQtXml、libQtGui 和 libpoppler-qt4 或 libpoppler-qt5）。PS 插件依赖于 libQtCore、libQtGui 和 libspectre。DjVu 插件依赖于 libQtCore、libQtGui 和 libdjvulibre。Fitz 插件依赖于 libQtCore、libQtGui 和 libmupdf。
由于缺乏维护者，Fitz 插件目前被视为实验性的。它还缺乏对各种功能的支持，例如元数据、加密、文本搜索、文本提取、表单字段和注释。
它是使用“lrelease qpdfview.pro”、“qmake qpdfview.pro”和“make”构建的。它是使用“make install”安装的。安装路径在“qpdfview.pri”中定义。
已安装的Qt5工具和依赖项qpdfview：
sudo apt install libcups2-dev libmupdf-dev libdjvulibre-dev libspectre-dev libpoppler-qt5-dev qttools5-dev-tools qtbase5-dev qt5-qmake cmake
pwdfview使用以下命令进行编译：
lrelease qpdfview.pro
qmake qpdfview.pro
make
最后一个make命令产生以下带有错误的输出：
qpdfview-0.5$ make

根据这个答案，问题似乎出在源代码中。但我不确定。可能是我错过了一些额外的依赖项。将继续调查，但可能有人已经成功编译了这个程序？
