我在一個costum路徑/home/luca/ParallelOpenCV/install_icpc/lib，那裏是libopencv_core.so安裝OpenCV的：

[email protected]:~$ ldd /home/luca/ParallelOpenCV/install_icpc/lib/libopencv_core.so

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

我加入了路徑LD_LIBRARY_PATH和我執行ldconfig，但：

[email protected]:~$ ldd libopencv_core.so 
ldd: ./libopencv_core.so: No such file or directory

我是什麼失蹤？

從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)

你的命令的輸出：

[email protected]:~$ ldd libopencv_core.so 
ldd: ./libopencv_core.so: No such file or directory

說，程序或在命令行指定的共享對象理應不在存在隱含目錄= ./ = /home/luca。我們知道它存在於/home/luca/ParallelOpenCV/install_icpc/lib。

如果運行ldd文件，其中文件，shell擴展後，是現有文件的路徑名，然後ldd將顯示動態依賴該文件的，通過動態鏈接器發現了它通常依賴於目前的ldconfig配置及其通常的操作方式 LD_LIBRARY_PATH環境設置。它不會搜索您的系統中的文件，該文件可能是文件的備用候選文件，該文件不存在並顯示這些候選文件的動態相關性。
