Question

我已阅读this，this和this。

我已在服务路径/home/luca/ParallelOpenCV/install_icpc/lib中安装了OpenCV，其中有libopencv_core.so：

luca@jarvis:~$ ldd /home/luca/ParallelOpenCV/install_icpc/lib/libopencv_core.so
    linux-vdso.so.1 =>  (0x00007ffccb389000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f46af719000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f46af410000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f46af1f2000)
    librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f46aefea000)
    libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f46aedd0000)
    libimf.so => /opt/intel/compilers_and_libraries_2017.1.132/linux/compiler/lib/intel64/libimf.so (0x00007f46ae8e3000)
    libsvml.so => /opt/intel/compilers_and_libraries_2017.1.132/linux/compiler/lib/intel64/libsvml.so (0x00007f46ad9d8000)
    libirng.so => /opt/intel/compilers_and_libraries_2017.1.132/linux/compiler/lib/intel64/libirng.so (0x00007f46ad663000)
    libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f46ad2e0000)
    libiomp5.so => /opt/intel/compilers_and_libraries_2017.1.132/linux/compiler/lib/intel64/libiomp5.so (0x00007f46acf3d000)
    libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f46acd27000)
    libintlc.so.5 => /opt/intel/compilers_and_libraries_2017.1.132/linux/compiler/lib/intel64/libintlc.so.5 (0x00007f46acabc000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f46ac6f3000)
    /lib64/ld-linux-x86-64.so.2 (0x000055f67574e000)

我添加了LD_LIBRARY_PATH的路径并执行了ldconfig，但是：

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

我错过了什么？

来自man ldd： -

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

表示程序或共享对象应该在上指定隐含目录中不存在命令行 = ./ = /home/luca。我们知道它存在于/home/luca/ParallelOpenCV/install_icpc/lib。

如果您运行ldd 文件，其中 file ，在shell扩展后，是路径名现有文件，然后ldd将显示动态依赖项该文件的内容，由动态链接器发现，并且通常依赖于它当前ldconfig配置及其对操作员的通常考虑 LD_LIBRARY_PATH环境设置。它不会搜索您的系统对于可能是不存在的文件的备用候选文件并显示这些候选人的动态依赖关系。

ldd无法找到图书馆
