--enable-`module`=shared
1. Build and install a distributed Apache module, say mod_foo.c,
into its own DSO mod_foo.so:
$ ./configure --prefix=/path/to/install --enable-foo=shared
$ make install
2. Build and install a third-party Apache module, say mod_foo.c,
into its own DSO mod_foo.so:
$ ./configure --add-module=module_type:/path/to/3rdparty/mod_foo.c --enable-foo=shared
$ make install
3. Configure Apache for later installation of shared modules:
$ ./configure --enable-so
$ make install
4. Build and install a third-party Apache module, say mod_foo.c,
into its own DSO mod_foo.so outside of the Apache source tree using apxs:
$ cd /path/to/3rdparty
$ apxs -c mod_foo.c
$ apxs -i -a -n foo mod_foo.la
本文针对 4 进行举例 编译一下 mod_usertrack：
### httpd-2.0.58/modules/metadata
# apxs -c mod_usertrack.c
/data/apache/build/libtool --silent --mode=compile gcc -prefer-pic \
-DAP_HAVE_DESIGNATED_INITIALIZER -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE \
-g -O2 -pthread -I/data/apache/include -I/data/apache/include -I/data/apache/include \
-c -o mod_usertrack.lo mod_usertrack.c && touch mod_usertrack.slo
/data/apache/build/libtool --silent --mode=link gcc -o mod_usertrack.la \
-rpath /data/apache/modules -module -avoid-version mod_usertrack.lo
# apxs -i -n usertrack_module .libs/mod_usertrack.so
/data/apache/build/instdso.sh SH_LIBTOOL='/data/apache/build/libtool' \

Warning! dlname not found in /data/apache/modules/mod_usertrack.so.
Assuming installing a .so rather than a libtool archive.
chmod 755 /data/apache/modules/mod_usertrack.so
