我有一个二进制文件，其中ldd显示了意外的依赖项和libicuuc（来自“ icu”）。
#ldd A [...] libxml2.so.2 => /usr/lib64/libxml2.so.2 (0x00007faaf9722000) libicuuc.so.49 => /usr/lib64/libicuuc.so.49 (0x00007faaf5689000)
由于在该系统上libxml动态依赖于libicuuc，因此ldd最终会找到它是有意义的，但是是否期望libicuuc也出现在A的ldd输出中？是否有一些命令仅检索链接为依赖项依赖关系的库？
ldd 显示启动应用程序或加载共享库时需要加载的所有库。
ldd
readelf -d 仅显示二进制文件的直接依赖项。
readelf -d

是否有一些命令仅检索链接为依赖项依赖关系的库？
您可以设置ldd和readelf -d输出的差。
