查看linux 下二进制文件依赖信息

ldd
: 列出一个可执行文件在运行时需要的共享库信息

ar : 创建静态库，插入，删除，列出和提取成员

strings : 列出文件中的所有可打印字符串

strip : 从目标文件中删除符号表信息

nm : 列出目标文件中符号表中定义的符号

size : 列出目标文件中节的名字和大小

readelf : 显示一个木边文件完整结构，包括elf头中的编码的所有信息，包含size和nm的功能

objdump : 所有二进制工具之母。能够显示一个目标文件中的所有信息，它最有用的功能是反汇编.text节中的二进制指令

（1）arm-linux-gcc编译的程序：若有一个名为test1的可执行程序

#readelf -a "./test1" | grep "Shared"

结果：

0x00000001 (NEEDED) Shared library: [libQtSql.so.4]

0x00000001 (NEEDED) Shared library: [libQtGui.so.4]

0x00000001 (NEEDED) Shared library: [libQtNetwork.so.4]

0x00000001 (NEEDED) Shared library: [libQtCore.so.4]

0x00000001 (NEEDED) Shared library: [libpthread.so.0]

0x00000001 (NEEDED) Shared library: [libstdc++.so.6]

0x00000001 (NEEDED) Shared library: [libm.so.6]

0x00000001 (NEEDED) Shared library: [libgcc_s.so.1]

0x00000001 (NEEDED) Shared library: [libc.so.6]

（2）gcc编译的程序，可在pc上执行的名为test1的可执行程序：

#ldd test1
