emacs export to PDF impossible due to missing pdflatex

[Quiliro Ordonez]

Emacs is capable of exporting to PDF by the use of pdflatex. This
program is available in Trisquel and PureOS (as a Debian inheritance) by
way of the 'texlive-latex-base' package. With Guix, even after
installing 'texlive-base' package (which depends on
'texlive-latex-base'), Emacs would give the error of missing 'pdflatex'
when exporting to PDF. The only solution to exporting to PDF on Emacs on
a foreign distro is to install 'texlive-latex-base' via 'sudo apt
install'. On GSD (Guix System Distribution) it is impossible to export
to PDF on Emacs.

“pdflatex” is provided by “texlive-bin”.

I have yet to write a section in the manual to explain how LaTeX on Guix
systems works.  And maybe texlive-base ought to include texlive-bin.

Thank you! how did you know?

I don't think my knowledge is enough to help with this. But if I can be
of help, I will be glad to.

I think this is a more general question:  Guix currently lacks a way to search
files in substitutes.  It would be nice to have this feature :D

I agree.
Something faster than the plain:
  $ find /gnu/ -type f -name "stuff" -print

It's actually more than just a /gnu/store cache: it should be able to find files
in non-installed packages.

I agree that it is not always easy to know that pdflatex is provided
by texlive or recsel is provided by recutils, etc.
And it should be nice to search files in substitutes, e.g., to know
which package to install.
However, for this purpose I am not sure that the substitutes are the
right layer.
And a field "provide" should be added to the package record. I do not
know if it makes sense.
Or maybe something with "properties". I mean, there is less package
providing multiple binaries (as texlive) than package providing the
binary of its name.

Do you have another usage in mind?
When writing packages? Especially about the TeX package?


All the best,
simon

We can't do that in package declarations because they don't hold any information
on the resulting derivation.

The "file list" problem is essentially at the same level as "guix size".

This is the new output after installing texlive-bin and then exporting
to PDF on Emacs:

TeX Live 2017?  What version of Guix are you using?  This seems pretty old.

When did you last run “guix pull”?

Wow!
guix (GNU Guix) 0.15.0-8.71a78ba
I installed GSD just a few days ago. I supposed it must have been
updated on installation.
How can I have version 0.15? I must have down

I am pulling and updating now.

Installed texlive-bin and texlive-base with fairly new guix:
$ guix --version
guix (GNU Guix) 9d58e8819fdbc4c1c8a1ef6149e2d2376731a6a6
But I stil cannot export to PDF via Emacs:

This is pdfTeX, Version 3.14159265-2.6-1.40.19 (TeX Live 2018)

Re: emacs export to PDF impossible due to missing pdflatex

[Pierre Gambarotto]

Hello

I just stumbled on the same trouble myself.

I solved it by defining:

export TEXMFROOT=~/.guix-profile/share/

Here is the path I followed, for the curious one:

The error came from mktexfmt that did not find mktexlsr.pl: extract from 
the beginning of the file:

   $TEXMFROOT = `kpsewhich -var-value=TEXMFROOT`;
   if ($?) {
     die "$0: kpsewhich -var-value=TEXMFROOT failed, aborting early.\n";
   }
   chomp($TEXMFROOT);
   unshift(@INC, "$TEXMFROOT/tlpkg", 
"$TEXMFROOT/texmf-dist/scripts/texlive"); <- require use this
   require "mktexlsr.pl"; <- HERE COME THE ERROR

It uses kpsewhich to determine TEXMFROOT, then TEXMFROOT do search for 
mktexlsr.pl

By default:

$ kpsewhich -var-value=TEXMFROOT
/gnu/store/yyja7azsicyf76b2vkki53bci6caqim9-texlive-configuration/share

I found thar mktexlsr.pl is in my profile:

# my profile is given by:

$ readlink -f ~/.guix-profile

/gnu/store/bp3j1n9r0r52rkbdcjkf3k4gakmg3216-profile

$ find `readlink -f ~/.guix-profile` -name mktexlsr.pl
/gnu/store/bp3j1n9r0r52rkbdcjkf3k4gakmg3216-profile/share/texmf-dist/scripts/texlive/mktexlsr.pl

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ : this should 
be TEXMFROOT

I don't know if this can be done automagically or not.

Hope this helps
