dlsym() on C++ symbols

dlsym() on C++ symbols

[Munagala V. S. Ramanath]

Hi,

After some experimentation (gcc-2.95.2, sparc-sun-solaris2.7) it seems
that I need to supply the mangled name of symbols to dlsym(). This
presents a problem because I would have to manually create the mangled
name for each symbol I need from a dynamically loaded C++ library.

Is there an easier way to do this ?  I looked in the GCC docs as well
as the dlopen/dlsym man pages but saw no discussion of this issue. Any
pointers would be much appreciated. Thanks.

Yup.

Create a `map' in the shared library that maps user-specified names to
symbol addresses?  Or use the name mangling/unmangling routines from
libiberty.
