Let me state in advance: One might think this question would is for server fault, but I think is is Ubuntu (config) specific. In short: I have put libwkhtmltox.so in /usr/local/lib as stated in installation instructions linked below, but it appears the library is not loaded. I am trying to install php-wkhtmltox, a php extension for wkhtmltox on my local desktop (Ubuntu 12.04). I have extracted the source and changed to the corresponding directory. After running phpize, ./configure fails at checking for libwkhtmltox support... yes, shared not found configure: error: Please install libwkhtmltox I suspect the reason the library is not loaded is that the path is not checked!? how do I proceed? Here are instructions I followed: http://davidbomba.com/index.php/2011/08/04/php-wkhtmltox/ http://roundhere.net/journal/install-wkhtmltopdf-php-bindings/
