有人可以告诉我为什么在尝试安装libpar2时可能会遇到这些错误吗？

据我所知，sigc ++ - 2.0已正确安装
root@a:/home/g/dnlds/libpar2# ls /usr/lib/libsigc*.so
/usr/lib/libsigc-2.0.so@
root@a:/home/g/dnlds/libpar2# pkg-config --list-all|grep -i sigc
sigc++-2.0 libsigc++ 2 - Typesafe signal and callback system for C++

没有启发，但这确实解决了我的问题。
之前我从未遇到过这个网站但他们索引当前37834个slackware软件包，我得到了libpar2和libsigc ++的软件包，并且安装时没有发生任何事故。
