Question

我正在使用Centos 6.6，并且有一个共享库，构建生成的共享库使用多个可执行文件，使用此共享库的任何可执行文件都无法找到它，如ldd所示。我可以找到图书馆：

$ locate libcs.so.1
/opt/cloudshield/lib/libcs.so.1

ldd显示以下内容：

$ sudo ldd /opt/cloudshield/lib/libcs.so.1
ldd: warning: you do not have execution permission for `/opt/cloudshield/lib/libcs.so.1'
    linux-vdso.so.1 =>  (0x00007ffff4fff000)
    libc.so.6 => /lib64/libc.so.6 (0x00007f7a0fd56000)
    /lib64/ld-linux-x86-64.so.2 (0x000000340ba00000)

$ sudo ldconfig -v | grep libcs.so.1

是不是因为内核库linux-vdso.so.1？

Executable cannot find the library libcs.so.1:

将/opt/cloudshield/lib/添加到您的LD_LIBRARY_PATH环境变量中，例如：

LD_LIBRARY_PATH=/opt/cloudshield/lib
export LD_LIBRARY_PATH
