Topic: undefined symbol: gdImageWebpCtx

Hello!
Thanks for your work. I'm using your PHP repos since 2014.
I'm upgrading PHP on a server and I get this message:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/gd.so' - /usr/lib64/php/modules/gd.so: undefined symbol: gdImageWebpCtx in Unknown on line 0
PHP 5.6.30 (cli) (built: Jan 20 2017 08:02:17)

I've installed

#rpm -q php php-gd gd-last
php-5.6.30-2.el6.remi.x86_64
php-gd-5.6.30-2.el6.remi.x86_64
gd-last-2.2.4-1.el6.remi.x86_64

Do you have an idea how can I make GD run?
Thanks again!

Re: undefined symbol: gdImageWebpCtx

Hey!
Thank you for the quick reaction. I was about to write again - the module started loading after I removed libgd.* from /usr/lib,lib64 and local/lib.

Otherwise the output of php -v, ldd and rpm -q is the same as yours.

It is loading fine now after removing libgd.so from /usr libs
