Hi Guys,
I tried an experiment that failed. dlopen is documented
as invoking _init when linking is complete and dlclose
as calling _fini. So, I went and tried to use this feature.
Unfortunately, when I invoked gcc as the linker, it decided
to forcibly include a couple of no-op routines by the same
name and choked. Reading man pages and GCC sources got me
nowhere vis-a-vis skipping the no-op routines. As the
linker invocation specialists, I'm appealing to you :-).
Is there supposed to be a way to tell GCC/collect2/ld to
let me supply my own _init and _fini routines? Or, am I
required to have a pre-determined external name that I
must reference? If so, what is the point of _init?
*sigh*.
P.S. I did a ``gcc -v'', grabbed the collect2 invocation
and deleted the file containing the unwanted externals.
Using that invocation resulted in a perfectly working
shared library with my own _init routine. Too clumsy for
real use, tho.
