Simon,
I am trying to load the PHP extension shared library on Linux and
getting the following error:
Unable to load library:
/home/delfinoj/Tuscany/apache-deploy/cpp/sca/extensions/php/lib/libtuscany_sca_php.so:
/usr/lib/httpd/modules/libphp5.so: undefined symbol: ap_loaded_modules
Does that ring a bell? I linked libtuscany_sca_php.so with libphp5.so,
am I missing a library?
Thanks,

Mmmm, that's not good. The ap_loaded_modules is an HTTPD symbol. PHP
uses
