我怎样才能找到一个ELF二进制C ++中所需的动态库？ [英] How can I find the dynamic libraries required by an ELF Binary in C++?

问题描述

我怎样才能得到全部是用C ++在linux的ELF程序所需的动态库的列表？

How can I get a list of all the dynamic libraries that is required by an elf binary in linux using C++?

有一次，我已经成功地提取二进制我可以通过在 PATH 搜索找到实际的文件中的信息（文件名），但我一直没能够找到关于从ELF二进制提取重整的信息的任何信息。

Once I've managed to extract the information (filename?) from the binary I can find the actual file by searching through the PATH, but I haven't been able to find any information regarding extracting unmangled information from the ELF binary.

思考？

推荐答案

您可以拨打readelf -d程序，并解析输出：

You can call "readelf -d" program and parse the output:

readelf -d /usr/bin/readelf | grep NEEDED
 0x0000000000000001 (NEEDED)             Shared library: [libz.so.1]
 0x0000000000000001 (NEEDED)             Shared library: [libc.so.6]
