Linking static libs into shared libs

Linking static libs into shared libs

[Alexander.Schmid]

Hi everybody,

I´m trying to create a shared lib, that needs some static libs to be created.
But when I try to link the shared lib against an executable, I get unresolved
externals.
Can anybody tell me what I did wrong? Is the "tunneling" of functions of a
static lib through the shared lib not possible?

Here´s the situation (well, lets say what I did) in Detail:

- creating the static lib:    g++ -c libstatic.cpp
               ar rcs libstatic.a libstatic.o
-creating the shared lib: g++ -c -fPIC libshared.cpp
               g++ -shared -o libShared.so -static -lstatic -lanotherstatic

I hope someone can help me.

Thanks in advance,
Alex

Hi Alex,

What does the 'nm' and/or 'objdump' commands tell you about libShared.so,
libstatic.a and libanotherstatic.xxx?

You do realize that order is important, so if libanotherstatic.xxx has
dependencies in libstatic.a that they may not be resolved correctly.

Can you contrive a minimal toy example that exhibits this behavior?
