I would like you to try to do so using libtool...
Just replace:
---
sbin_PROGRAMS = openvpn
openvpn_SOURCES = ....
---
with:
---
lib_LTLIBRARIES = openvpn.la
openvpn_la_SOURCES = ...
openvpn_la_LDFLAGS = \
-module -shared -avoid-version -no-undefined
---
And add -Dmain=openvpn_main to AM_CFLAGS.
Alon.
