Environment :
I'm trying to install pdo, when executing
pecl install pdo
I got error messages like this :
I have googled a lot, but I still don't get it. I need at least a pointer on where I should look, thanks in advance.
I decided to remove php 5.4 then reinstall using this link : PHP 5.4 installation guide, thanks to Alex Howansky for your help, reading your "custom compile" answer gave me an insight to reinstall it, and it works good now, I don't have to install the pdo extension via pecl. Hopefully this will help everyone who's having the same problem as mine.
