我有一个.a文件,我想从中获取体系结构信息。在中运行file myFile.a结果file.a: current ar archive。如何获得有关文件包含的体系结构的更多信息?
file myFile.a
file.a: current ar archive
您还可以通过以下ar命令跳过命令并使用readelf:
ar
readelf -h <archive>.a | grep 'Class\|File\|Machine'
[00:32:15] /usr/lib $ readelf -h libxslt.a | grep 'Class\|File\|Machine' File: libxslt.a(attrvt.o) Class: ELF32 Machine: Intel 80386 File: libxslt.a(xslt.o) Class: ELF32 Machine: Intel 80386 ... #Trimmed this, it goes on a bit File: libxslt.a(transform.o) Class: ELF32 Machine: Intel 80386 File: libxslt.a(security.o) Class: ELF32 Machine: Intel 80386 [00:32:24] /usr/lib $
如果相关,这里是您可以从中获取的其他信息readelf -h。我只是用修剪了以上内容grep:
readelf -h
grep
File: libxslt.a(security.o) ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: REL (Relocatable file) Machine: Intel 80386 Version: 0x1 Entry point address: 0x0 Start of program headers: 0 (bytes into file) Start of section headers: 2548 (bytes into file) Flags: 0x0 Size of this header: 52 (bytes) Size of program headers: 0 (bytes) Number of program headers: 0 Size of section headers: 40 (bytes) Number of section headers: 16 Section header string table index: 13
这是输出为 一个 在目标文件libxslt.a,但它给每个文件相同的信息。
libxslt.a
