Recently I was configuring PHP with Mysql manually and it was really annoying to see the “Cannot find libmysqlclient under /usr” error message. The configure line I used to install PHP was
./configure --with-mysql --with-libdir=/usr/lib
and the error that I received was
checking for MySQL UNIX socket location... /var/lib/mysql/mysql.sock configure: error: Cannot find libmysqlclient under /usr. Note that the MySQL client library is not bundled anymore!
The error occurred because libmysqlclient wasn’t present in the /usr/lib directory. On further investigation, I noticed the libmysqlclient is installed in the /usr/lib64 directory because the server is a 64bit machine.
So the fix for the “mysql: Cannot find libmysqlclient under /usr” error message is to provide lib64 directory path in the configure line.
The configure line should read as follows:
./configure --with-mysql --with-libdir=lib64
That’s it.
