I tried to build xmlrpc as a shared extension (phpize, ./configure, make), but when it builds it didn't have dependences for libexpat and libiconv, but the expat, libiconv and XMLRPC_ functions are undefined.

While trying to fix this I rewrote the config.m4 to handle all the following build cases:

1)  built-in to PHP with libxmlrpc included from extension directory
    --with-xmlrpc

2)  built-in to PHP with shared libxmlrpc
    --with-xmlrpc --with-libxmlrpc=/usr/local

3)  built shared with libxmlrpc included from extension directory
    --with-xmlrpc=shared

4)  built shared with shared libxmlrpc
    --with-xmlrpc=shared --with-libxmlrpc=/usr/local


There is one part I don't like and that is the new option of --with-libxmlrpc is only used in a state where it is not equal to 'yes' or 'no'.  It would have a directory value, but I don't like how it I did it.

Is this the best way to handle it?  Comments?

For the new config.m4 to work, xmlrpc-epi-php.c needs this changed:

#ifndef PHP_WIN32
#include "php_config.h"
#endif

to:

#ifdef HAVE_CONFIG_H
#include "config.h"
#endif

Also what does PHP_FAST_OUTPUT do?

Thanks,

Brian

Can you please make your patch a unified diff (diff -u) which makes it easier for us to test against.

Your HAVE_CONFIG change seems to disregard the initial intention which was to provide functionality for Win32 users.  You might want to make that happen as well.

I'm looking into this..the provided patch is not the way to do it.

Let me know if I can help test.  

The thing for me is build option 3.  I did test 1 and 3, but I couldn't completely test 2 and 4 as I couldn't get xmlrpc to compile with the freebsd ports package of xmlrpc-c.  It did configure it correctly, just code problems with the freebsd ports verion.

The reason for the HAVE_CONFIG change was when building shared it would not pull in the COMPILE_DL_XMLRPC from the local copy of the config.h.  This made it a invalid extension because ZEND_GET_MODULE(xmlrpc) was not compiled in.  Sorry, I didn't think about how the WIN32 would do it and may need changed to handle that platform.

Thanks for you help!

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.
