关于以下错误，我想知道在ldd显示其路径时无法打开库文件libpcre.so.3。
$ sudo ./nginx
./nginx: error while loading shared libraries: libpcre.so.3: cannot open shared object file: No such file or directory
$ ldd nginx

$ ls -l /lib/x86_64-linux-gnu/libpcre.so*
lrwxrwxrwx 1 root root 17 Oct 31 2018 /lib/x86_64-linux-gnu/libpcre.so.3 -> libpcre.so.3.13.2
-rw-r--r-- 1 root root 456632 Mar 25 2016 /lib/x86_64-linux-gnu/libpcre.so.3.13.2
那我该如何解决？
更新：
请注意，我正在尝试使用自定义glibc构建，其中在nginx Makefile中使用了以下开关。
-Wl,--rpath=/opt/glibc-2.23-install \
-Wl,--dynamic-linker=/opt/glibc-2.23-install/lib/ld-2.23.so
其他信息如下所示
