Linking static lib into shared lib

[roman schindlauer]

Hello all,

I am trying to produce a shared library, which should be linked to a 
static lib itself, but haven't managed so far. I compiled raptor (lib 
for rdf processing) out of the box, which gave me both static 
(libraptor.a) and shared libs (libraptor.so.1). Now I am building a 
shared lib (librdf) that uses libraptor. the final application that uses 
this shared lib should only need this one, but not libraptor:

mystuff + static libraptor = librdf, shared lib, 'self-contained'

I did this to produce the shared lib:

  g++ -Wall -g -c -fPIC rdfInterface.c -o rdfInterface.o
  g++ -Wall -g -c -fPIC extTypes.c -o extTypes.o
  g++ -g -shared -Wl,-soname,librdf.so.1 rdfInterface.o \
      extTypes.o -lz -lm -L. -lraptor -o librdf.so.1.0

(assuming that libraptor.a is in the working dir)

This results in the following error:
/usr/lib64/gcc-lib/x86_64-suse-linux/3.3.4/../../../../x86_64-suse-linux/bin/ld: 
./libraptor.a(raptor_parse.o): relocation R_X86_64_32S against `a local 
symbol' can not be used when making a shared object; recompile with -fPIC
./libraptor.a: could not read symbols: Bad value

(What does -shared actually mean: that it PRODUCES a shared lib or that 
the linker should LINK dynamically to the specified libs? Then, what is 
-static?)

If I remove the libraptor.a from the working dir and put all the 
libraptor.so* there, everything works. librdf.so.1.0 is produced and 
used by some example application, wich is compiled as follows:

  g++ -Wall -g -c rdftest.c -o rdftest.o
  ...
  g++ -g -Wl,-rpath,. rdftest.o extTypes.o extInterface.o -ldl -o \
      rdftest

But then again, I need not only my librdf but also libraptor in the 
directory of the executable, which I want to avoid!

Who can help?
Thnxia,
Roman
