在 slackware 13.37 上安装 libpar2 时出错

Question

有人可以告诉我为什么在尝试安装 libpar2 时可能会出现这些错误吗？

... whole slew of warnings

make[1]: *** [libpar2.lo] Error 1
make[1]: Leaving directory `/tmp/SBo/libpar2-0.2'
make: *** [all] Error 2

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。我之前从未遇到过这个网站

但他们目前的索引为 37834 slackware 软件包，我获得了 libpar2 和 libsigc++ 的软件包，并且安装顺利。
