------ Solution --------------------
Is mysql-related extension enabled in the php. ini configuration file?
------ Solution --------------------
I don't know how you compile it.
-- With-mysql =/opt/mysql/server-5.5/
Note that the mysql path is added during php compilation.
If it is another compilation, mysql. so needs to be added in php. ini, but I only did this for mysqli.

After the compilation is successful, will php. ini be changed?
Cp php. ini-development/usr/l ......

------ Solution --------------------
Php. ini:
Extension_dir = ". :/usr/nc-home/php5/include/php/ext:/usr/nc-home/php5/lib/php:/usr/local/lib /"
Extension =/usr/nc-home/php5/lib/php/extensions/no-debug-non-zts-20090626/hello. so
------ Solution --------------------
Extensions/no-debug-non-zts-20090626/hello. so is your compiled path. after successful compilation, there will be a path prompt to copy the last hello. so to be modified to mysql. so

You will need re2c 0.13.4 or later

Then you should go to the next new
Wget http://sourceforge.net/projects/re2c/files/re2c/0.13.5/re2c-0.13.5.tar.gz/download
Tar-zxvf re2c-0.13.5.tar.gz
Cd re2c-0.13.5
./Configure & make install

Try adding -- with-zlib-dir = .

Modify it to -- with-zlib-dir =/usr/lib.
