Hi Bob,
Here is my configure and make console (Msys) for 7.0. My configure
command has some differences from yours, esp. it does not have
--enable-shared on it. Let me know if you want me to try it specifically
with your configure options.
FWIW, as I recall when I previously ran those few commands that created
pcre.dll for 7.1-RC4 after using the new configure and make, it didn't
work unless I had configured without excluding static. But with 7.0's
make, it created everything it needed for making pcre.dll and
pcreposix.dll despite having --disable-static on the configure command.
I'm sure it has much to do with 7.0's Makefile.in.
Regards,
Sheri
