I have been trying to build session support as a shared extension and here is what I have found.  It works fine if you us the phpize, ./configure, make method, but if you try building it shared while building PHP it will not work.

./configure --with-layout=GNU --enable-session=shared --with-mm=shared
<snip> (it works)
make
<snip>(while compiling main/internal_functions.c)
internal_functions.c:47: `phpext_ps_mm_ptr' undeclared here (not in a function)
internal_functions.c:47: initializer element is not constant
internal_functions.c:47: (near initialization for `php_builtin_extensions[6]')

--- internal_functions.c ---
zend_module_entry *php_builtin_extensions[] = {
        phpext_xml_ptr,
        phpext_standard_ptr,
        phpext_posix_ptr,
        phpext_pcre_ptr,
        phpext_mysql_ptr,
        phpext_ctype_ptr,
 phpext_ps_mm_ptr,
};


It seems that phpext_ps_mm_ptr gets added if --with-mm or --with-mm=shared is set.  Adding it with  --with-mm=shared is bad as it is not needed and doesn't include the right headers for that function anyway.  I have created a patch to fix this, but wanted to make sure this was the best way to fix it.  Is there a better way? Comments?

Thanks,

Brian

BTW,
  ./configure --with-layout=GNU --enable-session=shared --with-mm=no
and
  ./configure --with-layout=GNU --enable-session=shared --without-mm
will not build it shared either, but I am not worried about that.
