C++ ldd can'；找不到图书馆

我已经读过了，还有

我已经在costum路径

/home/luca/ParallelOpenCV/install\u icpc/lib

中安装了OpenCV，其中有

libopencv\u核心。因此

：

luca@jarvis:~$ ldd /home/luca/ParallelOpenCV/install_icpc/lib/libopencv_core.so
    linux-vdso.so.1 =>  (0x00007ffccb389000)

    /lib64/ld-linux-x86-64.so.2 (0x000055f67574e000)

我将路径添加到

LD\u LIBRARY\u path

并执行了

ldconfig

，但是：

luca@jarvis:~$ ldd libopencv_core.so
ldd: ./libopencv_core.so: No such file or directory

我错过了什么？

NAME

       ldd - print shared object dependencies
SYNOPSIS         top

       ldd [option]... file...
DESCRIPTION

       ldd prints the shared objects (shared libraries) required by each
       program or shared object specified on the command line.  An example
       of its use and output is the following:

       $ ldd /bin/ls
               linux-vdso.so.1 (0x00007ffcc3563000)
               libselinux.so.1 => /lib64/libselinux.so.1 (0x00007f87e5459000)
               libcap.so.2 => /lib64/libcap.so.2 (0x00007f87e5254000)
               libc.so.6 => /lib64/libc.so.6 (0x00007f87e4e92000)
               libpcre.so.1 => /lib64/libpcre.so.1 (0x00007f87e4c22000)
               libdl.so.2 => /lib64/libdl.so.2 (0x00007f87e4a1e000)
               /lib64/ld-linux-x86-64.so.2 (0x00005574bf12e000)
               libattr.so.1 => /lib64/libattr.so.1 (0x00007f87e4817000)
               libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f87e45fa000)

命令的输出：

luca@jarvis:~$ ldd libopencv_core.so
ldd: ./libopencv_core.so: No such file or directory

表示假定在上指定的程序或共享对象 命令行不存在于隐含目录=

/

=

/home/luca

中。 我们知道它存在于

/home/luca/ParallelOpenCV/install\u icpc/lib

中

如果运行

ldd

file，其中shell扩展后的file是路径名 然后，

ldd

将显示动态依赖项 动态链接器通常依赖于 当前的

ldconfig

配置及其对操作系统的通常考虑

LD\u库路径

环境设置。它不会搜索您的系统 对于可能是不存在文件的备选文件的文件 并显示这些候选对象的动态相关性
