wkhtmltopdf segfaults

Question

I am trying to put wkhtmltopdf onto a virtualbox'ed ubuntu 12.04 64bit server. So far no luck. The package from the repositories wants to have xserver running and the static version:

wkhtmltopdf google.com tesss.pdf

Segmentation fault

Any ideas how could I approach this?

Answer 1

Upgrade to 0.12.6.

I know this is an old issue but for those still running into this, try upgrading to the latest version (0.12.6 at the time of writing). A lot of these issues have been fixed in the last few releases.

After that, try adjusting your ulimit on your machine as others have mentioned.

Then finally, if you are showing the current and total pages in your header or footer, see this answer for a good tip and solution.

Basically, it got fixed around a year ago, but has still not been released. What a mess :(

Try using 0.10.0_rc2 version instead, which worked perfectly for me

The QPixmap errors are not causing the segmentation fault. In fact, adding the --disable-javascript option solves the issue. You will still get the warnings but the PDF is generated correctly. HTH.
