Fwd: why isn't libmysqld dynamically linked, was Re: why isn't mysqle a shared library?

[Ian Monroe]

Good news. This would solve the whole fPIC mess. (Monty is creator of MySQL.)

We could speed this along by finding someone to make a patch to their
Automake to do this. I explicitly don't volunteer for this job.  :)

Normally you link a library to an application and in this case a
static library is usual as easy to use as a dynamic one.

It should be quite easy to provide libmysqld both as a dynamic and a
shared library. I agree that we should look into doing this.
