wkhtmltopdf - unsupported version

Hi all,

I'm not sure whether this strictly classifies as a bug, but sharing my experience.

CentOS/CPanel server

I ran into the "The currently selected version of wkhtmltopdf () is not supported. Please update to a newer version." error whilst trying to get the wkhtmltopdf library working.

In further investigating, i could run the 'wkhtmltopdf' command through shell and produce a pdf.

It seems that when trying to run the command it does so via an absolute path to the library /home/username/public_html/sites/all/modules/print/lib/wkhtmltopdf

But when running this through command line i get the error:

Bus error

so in print_pdf.module line 629 i changed:

$cmd = realpath($print_pdf_pdf_tool) .' --version';

to

$cmd = 'wkhtmltopdf-amd64 --version';

and now works.

This may be of use to some why got their hosting provider to install the library, but are still having trouble getting it to work.
