Today when building LNMP to compile PHP, an error was reported: configure: error: jpeglib.h not found. This article will share with you how to solve such problems.

[root@cac3 php-5.6.22]# ./configure \
> --prefix=/usr/local/php5/ \
> - -enable-fpm \
> --enable-mbstring \
> --enable-bcmath \
> --enable-sockets \
> --with-config-file -path=/usr/local/php5/etc \
> --with-mysql=/usr/local/mysql/ \
> --with-mysqli=/usr/local/mysql/bin /mysql_con
mysql_config mysql_convert_table_format
mysql_config_editor mysql_convert_table_format
mysql_config -with-gettext \
> --with-jpeg-dir

After executing the above command, the following error message appears:

configure: error: jpeglib.h not found.

[root@cac3 php-5.6 .22]# rpm -qa | grep libjpeg
