[f2py] gfortran with static and shared libs

I have so Fortran sources, I would like to use from Python. I would like to link 
my objects with:

lib1:  a STATIC lib (3rd party)

libs2: SHARED libs of gfortran

lib3:  another STATIC lib (3rd party)

More precisely, I would like to search all those libs in that order. That is, 
for example: If there is a symbol or function in libs2 AND in lib3, I would like 
to use that of libs2. But there are symbols in lib3, which I need.

Can I do such things with f2py? If yes: How? Can anybody help?


I tried the following:

***A***

If I do: f2py ... -llib1 -lib3, I get:

/usr/bin/gfortran -Wall -Wall -shared ...xxxmodule.o .../fortranobject.o 
obj.o  obj.o ...-Lpath -llib1 -lib3 -lgfortran -o ./xxx.so

/usr/bin/ld: path/lib3.a(stop.o):

relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a 
shared object; recompile with -fPIC

path/lib3.a: could not read symbols: Bad value

***B***

If I do: f2py ... -llib1, I get, when importing the module:

ImportError: ./xxx.so: undefined symbol: _gfortran_copy_string

Sure, I did not link lib3. That's why gfortran_copy_string is missing. It's 
seems not to be included in libs2. But 3rd party says: It is included in lib3.
