Is this my error or a bug?

Is this following due to a bug in either Payflow Pro SDK or in PHP or my messup? It just seems to odd that the warning is for pfpro_version and then the configtest fails because of pfpro_version. Here are the errors and code it is using: ----When making PHP---- root@server5:/usr/local/phpApache/php-4.0.4pl1# make > make.out pfpro.c: In function `php_if_pfpro_version': pfpro.c:129: warning: initialization makes pointer from integer without a cast root@server5:/usr/local/phpApache/php-4.0.4pl1# ----When doing configtest---- root@server5:/usr/local/phpApache/php-4.0.4pl1# ../../apache/bin/apachectl conf igtest Syntax error on line 213 of /usr/local/apache1317/conf/httpd.conf: Cannot load /usr/local/apache1317/libexec/libphp4.so into server: /usr/local/apa che1317/libexec/libphp4.so: undefined symbol: PNVersion root@server5:/usr/local/phpApache/php-4.0.4pl1# ----The code that the error is in(../php-4.0.4pl1/ext/pfpro/pfpro.c)---- /* {{{ proto string pfpro_version() Returns the version of the Payflow Pro library */ PHP_FUNCTION(pfpro_version) { if (ZEND_NUM_ARGS() != 0) { WRONG_PARAM_COUNT; } RETURN_STRING(PNVersion(), 1); } /* }}} */ Thanks, -Bob
