When you try to compile your PHP on a CentOS 64bit system, you can run into the following with just the default parameters, about not finding the MySQL development libraries.
First, make sure you have those libraries installed.
# yum install mysql-devel
And see if your configure command outputs something similar to this.
# ./configure –with-mysql …
checking for MySQL support… yes
checking for specified location of the MySQL UNIX socket… no
checking for MySQL UNIX socket location… no
checking for mysql_close in -lmysqlclient… no
checking for mysql_error in -lmysqlclient… no
configure: error: mysql configure failed. Please check config.log for more information.
You need to specify the –with-libdir parameter at the very beginning of your configure command, to tell your compiler you’re using 64bit libraries.
# ./configure –with-libdir=lib64 –with-mysql …
# make
Alternatively, you can also use the following setup.
# LDFLAGS=-L/usr/lib64/mysql ./configure –with-mysql …
# LDFLAGS=-L/usr/lib64/mysql make
If you use the last method, it’s important to note that you need to specify the LDFLAGS
