Do you think enable jpeg on php?

locate jpeg

If you have already compiled the PHP source without JPEG support and then try to compile it again but with JPEG support, the new setting will get ignored.

Firstly remove the previous build by typing:

make clean

Then run configure again with the following options:

--with-jpeg-dir=

For example if your JPEG library is installed in:

/usr/lib/libjpeg.so

Then you should use:

--with-jpeg-dir=/usr/lib

for eg:

./configure --with-apxs2=/usr/local/apache2/bin/apxs --enable-bcmath --with-curl --with-curlwrappers --enable-ftp --with-gd --with-jpeg --with-jpeg-dir=/usr/lib --enable-mbstring --with-mcrypt --with-mhash --with-mysql --with-readline --with-zlib

To check if JPEG support is enabled in your new build use PHP's info option.
