Re: File generation from LaTeX src fails due to temporary PDF in wrong directory

[Christian Moe <mail@christianmoe.com>]

Hi,

Pardon the noise: It turned out to be a pretty obvious problem with my
setup that has now been resolved.

I had modified org-latex-pdf-process to use xelatex, and for some reason
my setup lacked the =-output-directory %o= switch. I should probably
have thought of that first, but the omission has had no ill effects on
ordinary PDF export, so I didn't run into any problem before trying to
use Babel with LaTeX.

Ihor and Pedro, thanks for checking.

Chris, I don't know why your attempts fail, but I'll be trying similar
things over the next days, so maybe I'll come back to you.

Yours,
Christian
