You should be able to just provide the libraries to the linker when linking your shared object. When *running* the application, your shared object (i.e. the loader) should transitively pull in the libs on which yours depends. You can check those dependencies using ldd your-lib. Hope this helps, Patric Thanks Patric, but unfortunately that's not what I want. In this case, these secondary libraries (e.g. libmpfr.so and libgmp.so) have to be present on the target machines together with an 'rpath' if they are in non-standard directories. My aim was to let the linker generate a big library which obseletes the secondary libraries.

[gentoo-user] prelink a dynamic library
Hi, I want to create a shared library, say libULIB.so, which needs additional shared libraries, e.g. libmpfr.so and libgmp.so . My users only use the functions provided by libULIB.so. Is there a means to prelink libULIB.so, so that the libraries libmpfr.so and libgmp.so are not needed by the user? I.e. instead of g++ Example.C -lUlib -lmpfr -lgmp it should be suffucient to say g++ Example.C -lUlib Given Ulib.o I've tried g++ -shared -o libUlib.so -fpic -Wl,-soname,libUlib.so \ -Wl,-rpath,$LIBPATH -Wl,-export-dynamic \ Ulib.o -L $LIBPATH -lmpfr -lgmp but I still need -lmpfr -lgmp to get an executable. Many thanks for a hint, Helmut. -- Helmut Jarausch Lehrstuhl fuer Numerische Mathematik RWTH - Aachen University D 52056 Aachen, Germany
