apxs/libtool does not emit -shared linker flag

           Summary: apxs/libtool does not emit -shared linker flag
           Product: Apache httpd-2.0
           Version: HEAD
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Build
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: afm@othello.ch


The libtool included with apache 2.0.43 does not emit the -shared
linker option in spite of the -module option given to it by apxs.
As a consequence, building a module fails in the link step, because
the apache core symbols ap_* remain unresolved. This happens on
Solaris 8 and Linux 2.4.10, both with gcc 2.95.3.

The problem does not affect modules included with apache, because
these modules use shlibtool for the link step (not apxs/libtool),
which does give -shared to the linker.

The problem seems to be well known, php e.g. does not use the -c
option of apxs, includes its own copy of libtool, and uses it differently
than apxs.

A workaround is to add -Wl,-shared to the apxs flags, but a less
inelegant fix, namely a fix to libtool, and in the meantime, some
documentation of the problem would be very desirable.
