我正在尝试执行一个二进制文件，它显示./xtensoftphone: error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory。该库确实安装在 下/usr/lib。我需要做些什么才能让二进制文件看到该库？我以为所有/usr/lib库都是可见的。

答案1
/usr/lib/libstdc++.so.5除了 之外，您真的还有 吗/usr/lib/libstdc++.so.6？这两者不兼容（也就是说，需要一个的程序无法与另一个一起工作，当然您可以同时安装两者）。您需要安装libstd++5包裹。
Ubuntu 10.04 不再有libstdc++5，但如果你需要它，你可以从backports 存储库。它在后续版本中被重新引入。
答案2
ldconfig每次更改库后都需要运行。如果有疑问，只需运行它，运行太频繁也不会有什么坏处。
如果这不能解决问题，请发布 的输出ldd xtensoftphone和 的内容/etc/ld.so.conf（以及 下的任何文件/etc/ld.so.conf.d），然后我们再看看。
答案3
尝试将库的位置添加到 LD_LIBRARY_PATH
