For a static library (.a file), how to list the module-level dependencies of it?
I know for a shared library (.so), we can use objdump or readelf to do this:
objdump -p test.so
or
readelf -d test.so
I can get something like
NEEDED libOne.so
NEEDED libc.so.6
But for a static library, I can only get the dependencies in symbol-level, for example, by running
objdump -T test.a
I will get some thing like:
00000000 DF UND 00000000 QByteArray::mid(int, int) const
00000000 DF UND 00000000 QUrl::fromEncoded(QByteArray const&)
00000000 DF UND 00000000 QFileInfo::fileName() const
But I need the information in module-level, does anyone know how to get that information?

A static library have no such list of dependencies.
A static library is nothing more than an archive of object files. And as object files doesn’t know what libraries they depend on, neither can a static library.
