Usually that means you have to add -W,l,-no-undefined to the link
command line.
You also have to patch a few in the build system to compensate for some
other braindead issues, such as the fact that it assumes that binaries
have no extension and that shared objects are named .so. Naming the
shared objects .so is fine if you only plan to dlopen() them, but if you
want full PHP functionality (such as a working CLI) you need them named
.DLL.
The attached patch does this in a rather crude way... it skips using
libtool, which is ugly, but at the time when I was looking at this it at
least got me past the build problems. You can build most PHP modules
dynamically with this (or at least, you could last time I checked) but
some of them would segfault when loaded. There's also a serious problem
with image addresses, and I remember having to manually rebase the php
modules to a certain range to get the server to start.
This was with Apache 1.x, no clue if it will work for 2.x. No
guarantees that there hasn't been bitrot since I last looked at this.
