I have two php versions on one server. One of them has mysql support, the other has mssql support and is used to run scripts via the comand line. I am trying now to compile in mysql support to the command line one and I keep getting: configure: error: Cannot find MySQL header files under yes. checking for specified location of the MySQL UNIX socket... no checking for MySQL UNIX socket location... no configure: error: Cannot find MySQL header files under /usr/lib/php/modules. Note that the MySQL client library is not bundled anymore! I've tried a few directories. I chose this last one because there was a mysql.so and libmysql.so file in there. I must have it as the other version has support. Thanks!!! Here is my config: ./configure '--with-mysql=/usr' '--with-mssql=/usr/local' '--disable-libxml' '--disable-dom' '--disable-simplexml' '--disable-xml' '--disable-xmlreader' '--disable-xmlwriter' '--without-pear' Here is the config from the working version yet I don't know how it works as it says --no mysql ./configure' '--build=i386-redhat-linux' '--host=i386-redhat-linux' '--target=i386-redhat-linux-gnu' '--program-prefix=' '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/bin' '--sbindir=/usr/sbin' '--sysconfdir=/etc' '--datadir=/usr/share' '--includedir=/usr/include' '--libdir=/usr/lib' '--libexecdir=/usr/libexec' '--localstatedir=/var' '--sharedstatedir=/usr/com' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--cache-file=../config.cache' '--with-libdir=lib' '--with-config-file-path=/etc' '--with-config-file-scan-dir=/etc/php.d' '--disable-debug' '--with-pic' '--disable-rpath' '--with-bz2' '--with-curl' '--with-exec-dir=/usr/bin' '--with-freetype-dir=/usr' '--with-png-dir=/usr' '--enable-gd-native-ttf' '--without-gdbm' '--with-gettext' '--with-gmp' '--with-iconv' '--with-jpeg-dir=/usr' '--with-openssl' '--with-png' '--with-pspell' '--with-expat-dir=/usr' '--with-pcre-regex=/usr' '--with-zlib' '--with-layout=GNU' '--enable-exif' '--enable-ftp' '--enable-magic-quotes' '--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' '--enable-sysvmsg' '--enable-track-vars' '--enable-trans-sid' '--enable-yp' '--enable-wddx' '--with-pear=/usr/share/pear' '--with-kerberos' '--enable-ucd-snmp-hack' '--with-unixODBC=shared,/usr' '--enable-memory-limit' '--enable-shmop' '--enable-calendar' '--enable-dbx' '--enable-dio' '--with-mime-magic=/etc/httpd/conf/magic' '--without-sqlite' '--with-libxml-dir=/usr' '--with-xml' '--with-apxs2=/usr/sbin/apxs' '--without-mysql' '--without-gd' '--without-odbc' '--disable-dom' '--disable-dba'p
