linux - locate 找到库但 ldconfig 没有

Question

我正在使用 Centos 6.6，并且有一个共享库，该构建生成由多个可执行文件使用，并且使用此共享库的任何可执行文件都找不到它，正如 ldd 所见。 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

是不是内核库linux-vdso.so.1的问题？

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

LD_LIBRARY_PATH=/opt/cloudshield/lib
export LD_LIBRARY_PATH
