PHP Fatal error: Call to undefined function imagewebp() in

[guidonline]

Hi all,

I was wondering why the imagewebp() function is not working on the virtual machine of a customer. When you see the phpinfo page (http://urt.co/3wTn). I can see that the PHP version is 5.6.> and that GD is installed. But when I try to use the imagewebp() function, this error occur: PHP Fatal error: Call to undefined function imagewebp()

Can anyone tell me what the problem can be?

Thanks!

Nobody can help me with this problem? I tried to downgrade PHP to 5.4 and build everything again (with ./build clean ./build all) but nothing worked.

Hello,

You should install PHP with webp support if you want to utilize the feature:

[TABLE="class: doctable table, width: 824"]
[TR="bgcolor: #E6E6E6"]
[TD]webp[/TD]
[TD]To enable support for webp add --with-vpx-dir=DIR . Available as of PHP 5.5.[/TD]
[/TR]
[/TABLE]
