PHP compilation error configure error Cannot find libmysqlclient under usr Solution

An error occurred while compiling PHP5.2.6 on 64-bit Red Hat Enterprise Linux AS release 4.7. mysql was installed using RPM. The PHP compilation code is AS follows:

. /Configure -- prefix =/usr/local/php -- with-mysql -- with-apxs2 =/usr/local/apache/bin/apxs -- with-openssl -- with-curl -- enable-xml -- with-mcrypt -- with-ttf -- enable-magic-quotes -- enable-fastcgi -- enable-mbstring -- with-iconv -- enable-mbstring -- with-gd -- with-jpeg-dir -- with-png-dir -- with-zlib-dir -- enable-sysvsem: checking for specified location of the MySQL UNIX socket... nochecking for MySQ L unix socket location... noconfigure: error: Cannot find libmysqlclient under/usr. Note that the MySQL client library is not bundled anymore!

Find libmysqlclient and find it in the/usr/lib64/mysql/directory. so.16.0.0 is a soft connection. PHP searches for/usr/lib/by default, so it cannot be found. after finding the problem, we can solve it.

Similar issues include:

/usr/lib/libjpeg.so -> /usr/lib64/libjpeg.so

Solution:

1.

cp -rp /usr/lib64/mysql/libmysqlclient.so.16.0.0 /usr/lib/libmysqlclient.so

2.

/usr/lib64/libmysqlclient.so -> libmysqlclient.so.16.0.0/usr/lib/libmysqlclient.so -> /usr/lib64/libmysqlclient.sochecking whether to enable embedded MySQLi support… nochecking for mysql_set_server_option in -lmysqlclient… noconfigure: error: wrong mysql library version or lib not found. Check config.log for more information

After testing, the following solutions are found:

(Php-xxxxx is the php file name, indicating the path)

# cd /usr/local/src/php-xxxxx/ext/mysqli# yum -y install mysql-devel# /phpize# ./configure –with-php-config= /php-config –enable-embedded-mysqli=shared –enable-shared# make# make install

At this time, the screen will print the path generated by mysqli. so, just load it in php. ini.

/usr/bin/ld: cannot find -lmysqlclient
