Re: [O] PDF-tools... and LaTeX (solved)

[AW]

Sorry for the noise, to use PDF Tools instead of Okular I just had to write 
into my .emacs:

(pdf-tools-install) 

 (TeX-view-program-selection (quote (((output-dvi style-pstricks) "dvips and 
gv") (output-dvi "xdvi") (output-pdf "PDF Tools") (output-html "xdg-open"

Yes, well, this is already part of the code I posted, see above. However, 
thank you, I admit my question is a little bit OT!

So when-let is not defined above, and it is not defined by emacs, so you
got to get the definition from somewhere. Go back to the link and you'll
see further down that the OP complains about the same thing. The
solution seems to be

   (require 'subr-x)

That's because libpoppler is essentially a library version of xpdf:

$ yum info poppler
Loaded plugins: auto-update-debuginfo, copr, etckeeper, langpacks
Installed Packages
Name: poppler
Arch: x86_64
Version : 0.26.2
Release : 9.fc21

Repo: installed
Summary : PDF rendering library

Description : Poppler, a PDF rendering library, is a fork of the xpdf PDF
: viewer developed by Derek Noonburg of Glyph and Cog, LLC.

Wow, as usual thanks Nick, great help and insights.

Say, LaTeX and xpdf and poppler and Okular are all great software--suggest
you try out xournal too:

apt-get install xournal

--shows .pdfs and many tools for editing .pdf's

Also, you're well aware of the Emacs/ELisp tools for .pdf's (
https://github.com/politza/pdf-tools); but, suggest you install and tinker
with CPAN/Perl's pdf-tools--well worth investigating.
