1、查看库的函数及变量
nm -D /usr/local/lib/liblog4cplus.so
log4/log4cplus-2.0.8$ nm -D /usr/local/lib/liblog4cplus.so
0000000000034aa0 T log4cplus_add_callback_appender
0000000000033980 T log4cplus_file_reconfigure
0000000000033810 T log4cplus_initialize
0000000000033ba0 T log4cplus_logger_exists
...
2、查看有关库的详细信息,包括段、符号表、重定位表等
objdump -x /usr/local/lib/liblog4cplus.so
log4/log4cplus-2.0.8$ objdump -x /usr/local/lib/liblog4cplus.so
/usr/local/lib/liblog4cplus.so: file format elf64-x86-64
Dynamic Section:
NEEDED libstdc++.so.6
NEEDED libm.so.6
NEEDED libpthread.so.0
NEEDED libc.so.6
NEEDED ld-linux-x86-64.so.2
NEEDED libgcc_s.so.1
SONAME liblog4cplus-2.0.so.3
3、查看有关库的详细信息,包括头部、段、符号表等
readelf 命令用于显示 ELF(Executable and Linkable Format)文件的信息,包括共享库
readelf -a /usr/local/lib/liblog4cplus.so
log4/log4cplus-2.0.8$ readelf -a /usr/local/lib/liblog4cplus.so
