Team

I've three different issues that I think are related to the same base problem. It appears the libtool complains of unresolved symbols. Instead of a warning it looks like this is a fatal error which prevents compiling

So far I have gotten this error in compiling subversion, apache, and mailutils (2.0 and 2.1). 


Error in make log
libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin shared libraries


*** Warning: This system can not link to static lib archive ../mailbox/libmailutils.la.
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have.
libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin shared libraries

Have to ask the newbie question here, is there an option to pass to the compiler to allow these packages to compile successfully?

So far none of these packages have produced working binaries when compiled with shared libraries. I can get apache to compile successfully by compiling the share items in (DSO) tho that confuses me.. I would have thought that wold be "static" instead of DSO but the docs say DSO. Maybe I am misreading it.. anyways...

Does a previous version of libtool have the same problem? I can't believe I am the only one running into this...
