php gd library does not support jpeg solution

I won’t go into details here about how I encountered this problem. If you have indeed installed the gd library, but find that it cannot support images in jpeg format, you can find the answer below.

The reason is that before compiling the gd library, the jpeg library path was not declared during configuration.

The solution is as follows:

32-bit system:

./configure –with-php-config=/usr/local/php5/bin/php-config
–with-jpeg-dir=/usr/lib

64-bit system

./configure –with-php-config=/usr/local/php5/bin/php-config
–with-jpeg-dir=/usr/lib64
