Hi,
I'm attempting to understand how the old dll's were created and how the
new ones are. That way, I can see the difference and explain the
situation clearly to a 3rd party.
However, if I download pcre-7.0 and do
$ ../pcre-7.0/configure --prefix=$PWD/../prefix --disable-static
--enable-shared
it only generates static libraries. Libtool complains that it has to.
The output of the make is attached.
How did anyone ever build a shared library on windows in the first
place?
Thanks,
Bob Rossi
