背景

如何将程序依赖的动态库拷贝到指定的目录?

例子

1、通过LDD查看依赖的动态库。

# ldd postgres

        libcap.so.2 => /lib64/libcap.so.2 (0x00007fb60e96f000)  
        libselinux.so.1 => /lib64/libselinux.so.1 (0x00007fb60e748000)  
        libgcrypt.so.11 => /lib64/libgcrypt.so.11 (0x00007fb60e4c6000)  
        libgpg-error.so.0 => /lib64/libgpg-error.so.0 (0x00007fb60e2c1000)  
        libdw.so.1 => /lib64/libdw.so.1 (0x00007fb60e079000)  
        libcap-ng.so.0 => /lib64/libcap-ng.so.0 (0x00007fb60de72000)

        libfreebl3.so => /lib64/libfreebl3.so (0x00007fb60d1a7000)  

2、写一个SHELL脚本,自动拷贝依赖的动态库。

vi test.sh  
  
deplist=$( ldd $1 | awk '{if (match($3,"/")){ print $3}}' )  
cp -L -n $deplist $2   
-L 表示拷贝文件(如果是软链,会拷贝到最终的文件)。  
-n 表示不覆盖已有文件。  

3、创建目标目录。

mkdir /tmp/lib  

4、将postgres依赖的动态库拷贝到目标目录

. ./test.sh /usr/pgsql-10/bin/postgres /tmp/lib/  
ll /tmp/lib
