对 c++ 来说很新，不过用其他语言编码了几年。我整天都被这个问题困扰着，我似乎无法弄清楚。

当我运行此处发布的代码时：http ://www.nongnu.org/fastcgipp/doc/2.1/a00004.html 我收到以下错误消息：

加载共享库时出错：libfastcgipp.so.2：无法打开共享对象文件：没有这样的文件或目录

使用ubuntu 13.10

我可以毫无问题地构建代码，但不能运行它。有一个libfastcgipp.so.2和libfastcgipp.so在/usr/local/lib/

我尝试从/usr/lib/libfastcgipp.so

编辑

ldd 命令的结果...

我通过如上所述创建文件的符号链接解决了这个问题，但在2最后添加了尾随数字，版本号。

例如：ln -s /usr/local/lib/libfastcgipp.so.2.0.0 /usr/lib/libfastcgipp.so.2

更新

再次遇到这个问题并且无法再次解决同样的问题，所以我发布了一个 docker 文件，它将让你的 fastCGI++ 脚本运行（可能只有我会使用它，但无论如何......）
