Is there a simple way to check that a C++ lib is complete,
that is that it does not have any external dependencies?

Thanks, Louis.

Hi,

A lib is something (I guess you mean a static library: the 'lib' is
vague) created by the linker... it's no more C++, may use some other
libraries or not (and again this definition is not precise at 100%
because can be linked statically with some of them).

Replying to your post in Windows you can use dumpbin /dependencies if
I remember well. In Linux there is another command: check the manual.

But... if the lib is only a wrapper to a dynamic loaded library you
are again in trouble.

   % nm -C libprefer.a | grep -iw U

Note that it's not enough; if the library contains foo.o and bar.o you
get to see foo.o's unresolved references to symbols in bar.o, and so
on.  A static library (in the usual sense) doesn't have its internal
dependencies resolved.

By the way, I suspect this is one of those cases where the original
poster could get a better answer if he explained what he wanted to
accomplish.
