I have a C++ shared library built using g++ 2.95.2 on HP-UX 11. The library
linked using the HP-UX linker not the GNU linker. The library gets
dynamically loaded with a call to shl_load(). When the library is loaded
nonlocal static initializations don't get executed. In fact I noticed that
if I link in the shared library statically then I can see a call stack that
includes some rather important sounding functions like __main() and
__do_global_ctors(). But if this library dynamically loaded using shl_load
then these functions don't seem to get called.
Any ideas?
Thanks in advance.
Ed

You have to use shl_findsym to get a pointer to the shared library
initializer routine and call it yourself.
