Now we have made it clear that the cause of the error is that FreeType is not added during PHP compilation.

Solution:

First, compile and install FreeType. Take 2.4.0 as an example:

Wget http://download.savannah.gnu.org/releases/freetype/freetype-2.4.0.tar.bz2tar-jxf freetype-2.4.0.tar.bz2cd reetype-2.4.0 # install to/usr/local/freetype./configure -- prefix =/usr/local/freetypemake & make install

Next we will re-compile PHP with Parameters--with-freetype-dir=/usr/local/freetype

./configure \... \... \--with-freetype-dir=/usr/local/freetype

Compile and restart php

kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`

FindFreeType SupportThe installation is successful!
