Call to undefined function: imagecreatefromjpeg()

While installing new Joomla modules I came across this PHP error (yep, still have to deal with PHP occasionally). I had PHP compiled from source on Ubuntu 10.04 as per earlier instructions. Quick check of phpinfo() indicated that while gd module was compiled in, it didn’t have JPEG support:

GD Support         enabled
GD Version         bundled (2.0.34 compatible)
GIF Read Support   enabled
GIF Create Support enabled
PNG Support        enabled
WBMP Support       enabled
XBM Support        enabled

Making sure that JPEG libraries are installed

sudo aptitude install libjpeg libjpeg-dev

and reconfiguring PHP with –with-jpeg-dir flag (the rest of the compilation process remains the same as here)

./configure --enable-fastcgi --enable-fpm --with-mcrypt --with-zlib 
--enable-mbstring --with-openssl --with-mysql --with-mysql-sock 
--with-gd --without-sqlite --disable-pdo --with-jpeg-dir=/usr/lib

and then restarting nginx

sudo /etc/init.d/nginx restart

helped to solve the problem.
