On one of my website hosting I do some image manipulation in php. Having recently moved to my VPS Hosting I find that it doesn't work anymore, and I get the following error
Call to undefined function imagecreatefromjpeg()

Seems like the GD library isn't active.
Anyone know how I activate it??

I'm sure support could do it for me - but I'm keen to learn these things for myself

David,

Please raise a support ticket. The VPS Hosting team will resolve this for you. I have asked them to enlist the steps for you so that you may do this yourself the next time.

Thanks Nick - I've raised a ticket #BKR-38429-260

Hi David

How did you install PHP? I have found that with my VPS Hosting it was better to compile it from source then all the modules are compiled directly into PHP making it perform better. During compiling I also tell it what type of system it's on with compiler flags so that it's tweaked to the CPU etc.

here's my php configure command, gd is added via the --with-gd

CFLAGS="-march=pentium4 -O2 -pipe -fomit-frame-pointer" ./configure --prefix=/usr/php --bindir=/usr/bin --sbindir=/usr/sbin --with-gd=/usr --with-apxs2=/usr/local/apache/bin/apxs --with-pspell=/usr --enable-soap --enable-exif --with-tidy --with-curl --with-png-dir=/usr --with-zlib-dir=/usr --enable-force-cgi-redirect --with-gettext --with-freetype-dir=/usr --with-jpeg-dir=/usr --enable-mbstring --with-xsl --with-pear=/usr/php/pear --with-config-file-path=/etc/php --with-mysqli=/usr/bin/mysql_config --without-sqlite --with-pdo-mysql=/usr --without-pdo-sqlite --with-mcrypt=/usr --with-bz2 --with-mysql=/usr

then you just compile with make -j6 && make install.

There is a good tutorial on how to find out suitable compiler flags on this page http://gentoo-wiki.com/Safe_Cflags#I...on_51xx.2F53xx

yeah okay I don't have gentoo, but the principle is the same. You can just add them as environment variables and configure picks them up.

David,

Sam has replied back to you. He did not enlist the steps for GD simply because there are a few complicated steps which are best done by the administrators. We are in no way underestimating your abilities, just that the VPS Hosting team would like to do it themselves.

Thank you for your understanding.

Your suggestion would be good for our system administrator but David has limited knowledge of Linux

True, but we all have to start from somewhere! We've all been n00bs at some point in our lives David did say that he wanted to learn things for himself.
