This time I will bring you a detailed explanation of the use of adding freetype expansion to the PHP GD library. What are the precautions for adding freetype expansion to the PHP GD library? The following is a practical case, let's take a look.

Linux version centos 6.6

Installation process (since the server is a distributed intranet server, yum cannot be used to install it. The following are download resources Compilation and installation after package):

Install freetype

Unzip freetype-2.3.9.tar.gz

Compile and install

./configure --enable-static --enable-shared (without specifying prefix, the .h file is installed to /usr/local/

include by default, The .a|.so file is installed by default in /usr/local/lib. If the directory is not specified, the installation of other resource packages will also go to this location.)

make && make install

Confirm freetype installation After success, recompile and install the GD library, add freetype support

Install the gd library, version 2.0.35

Since there are previous installation records, it is recommended Make clean first, otherwise the installation may fail

./configure --enable-shared --with-jpeg=/usr/local/include/ --with-freetype=/usr/local/ --with -png=/usr/local/include/

(It should be noted here that the path of --with-freetype=/usr/local/ is initially written as /usr/local/lib, and the result is always imported. Freetype failed, probably because the header file is not in this directory. It was successfully introduced after changing to the upper-level directory)

Confirm Support for Freetype 2.x library: yes

make && make install

After confirming that the installation is successful, recompile and install the PHP gd extension

php version 5.5.38

To install the gd expansion module separately, you need to cd to php-5.5.38/ext/gd

and execute phpize to generate a compiled file. If phpize is not introduced into the system, this file will be in the bin in the PHP installation directory

Be sure to execute make clean here first. This time, 8 servers were installed. 100% of the servers that were not executed make clean first were not installed successfully, and none were added to freetype support

./configure --with-php -config=/opt/php5.5.38/bin/php-config --with-jpeg-dir --with-png-dir --with-freetype-dir --with-zlib-dir --with-gd

Confirm that freetype 2 has been added during compilation

make && make install

Confirm whether the newly generated .so file is the same as the original introduction in php.ini The paths are the same. If they are different, you need to modify the extension in php.ini

After successful installation, restart php-fpm

ps axu |grep php |grep -v 'grep '|awk '{print $2}'|xargs kill -9

/php5.5.38/sbin/php-fpm

After successful restart, check the gd in
