Run-time linking

Run-time linking

Post by a.. » Sun, 19 Jun 1994 08:04:47

        I am interested in being able to
link object files with a running program.
Basically, I would like to write a function
that will return an appropriate function
pointer given the file-name of a .o file
and a function prototype and name.
        Is there any pre-existing code
that will do this? If not, I would appreciate
any advice from gcc gurus.

1. Removing indirect run-time link dependencies.

I'm developing an OpenGL application on a system
using XFree86 4.0.x.  Whenever I link the
application with, it also links to, since depends on
This means that I can' t run the
application on a system not using XFree86 3.3.x,
or any other X Server for that matter.  Is there a
way I can get the link to not include
in the list of required shared libraries for the
application?  If I link the program on a system
using XFree86 3.3.x, such that is not
a required shared library for the application, I
can still run it on an XFree86 4.0.x system, so I
know that having my application require directly is not necessary.  It isn't
clear to my why an application would want to
include the indirect shared library dependencies
since the run-time linker will handle these.

  Thanks for you help,
