Best way to get PHP5.6 GD functions available?

[adire]

Hi,

I'm sure this issue must have come up for people before, is there a tried and tested way to solve this on debian+symbiosis?

Call to undefined function imageantialias() in /srv/testsite.co.uk/public/htdocs/images/index.php on line 12

Thanks for all your help,
Craig

Best answer came from: http://refreshmentwars.blogspot.co.uk/2014/01/recompile-php-with-bundled-gd-library.html

If you run into any source not found issues, don't forget to uncomment src lines in /etc/apt/sources.list

Be aware this took several hours to run for me and then failed when running mysql tests, it looks it like tried to create tables locally as part of its tests.

Install build tools required to compile source code

apt-get install build-essential debhelper fakeroot

Obtain the PHP source code

cd /usr/src
sudo apt-get source php5

Install all dependencies required to build PHP5

sudo apt-get build-dep php5

Build the package

cd php5-x.x.x (replace 'x' correct version number)
sudo dpkg-buildpackage -rfakeroot

This will take some time. When the .deb is compiled, traverse back a folder.

cd ..

Install the required package*

sudo dpkg -i php5-gd_5.x.x.x.deb

*Don't forget to restart apache.

Wouldn't 'apt-get install php5-gd' just install the current library, or have I missed something?

The @adire best-answer link had it covered:

So there's no bundled libraries in Debian or Ubuntu. Debian policy does not build packages with embedded copies of 3rd party code. Due to upstream syncing issues, package maintainer animosity, and Debian policy, GD sources used for libgd in Debian are missing certain functions.

If you happily installed PHP with GD using apt-get install php5-gd you should be aware the following functions are missing

function imageantialias function imagecolormatch function imageconvolution function imagecreatefromxbm function imagecreatefromxpm function imagefilter function imagelayereffect function imagerotate function imagexbm

The php manual suggests things have moved on with php7.

7.2.0
imageantialias() is now generally available. Formerly it was only available if PHP was compiled with the bundled version of the GD library.

@TonyRogers I think you were right. Even using this compiled package I couldn't get it to actually install the missing gd method and in the end I modified the php website code to work around the problem.

It was compiled --with-gd etc so I couldn't see what if anything I was doing incorrectly.

That would absolutely do the trick by the look of it! Would you be as kind as to let me know what libraries you're needing?
