Can't build PHP 5.3.6 with MySQL 5.5.10

Hello! I'm trying to build PHP 5.3.6 in a server with MySQL 5.5.10, and I get this error: /usr/include/mysql/mysql/psi/mysql_thread.h:100: error: syntax error before "pthread_rwlock_t" /usr/include/mysql/mysql/psi/mysql_thread.h:100: warning: no semicolon at end of struct or union /usr/include/mysql/mysql/psi/mysql_thread.h:107: error: syntax error before '}' token /usr/include/mysql/mysql/psi/mysql_thread.h: In function `inline_mysql_rwlock_init': /usr/include/mysql/mysql/psi/mysql_thread.h:683: error: dereferencing pointer to incomplete type Full build log is available at: http://pastebin.com/g0kWwzye This only happens in CentOS-4 box with GCC v3.4.6; I can build PHP 5.3.6 with MySQL 5.5.10 in CentOS-5 without problems. Anyone knows how fix this problem? thanks!! Cheers, -- Santi Saez http://powerstack.org
