linking static libs into shared lib with libtool

[Ron Lange]

Hello,
I want to link a shared php extension which is using libtool in 
conjuction with automake/autoconf. This .so is using other libs, which I 
need to be statically linked into the module.

Actually I am quite confused of the php build mechanism, modifying the 
config.m4 doesn't cause the static libs linked into the shared one.  I 
modified the config_vars.mk by inserting just '-L/pathtolibs -llibname 
...' into the INCLUDES var...terrible way, I know...

Now the libs seems to be linked in, but during the use of the php-module 
it is concerning about unreachable shared objects, which I actually 
wanted to be linked statically in...

How you get libtool to link first the needed libs statically into the 
proper library then this lib into a shared object?

Regards
Ron
