LyX on foreign distro

LyX on foreign distro

[sirgazil]

Hello, I need some help :)

I'm using LyX 2.3.2-2 installed with Guix 
(a506a4c3801838c0b75b58dd2ac8bb0ccf4279fb) on a foreign distribution, 
and I noticed the following:

1. Buttons in the toolbar do not display icons, just text.
2. I'm getting a "LaTeX Error: File `utf8x.def' not found" when I try to 
export a document to PDF (see full error at the end of this message).

About the second problem, I don't know what I should install with Guix 
to fix it.

When working with LyX documents on Debian 9, I usually install the 
following packages and I can export the documents to PDF:

texlive-lang-SOME_LANGUAGE or texlive-lang-all
texlive-xetex
texlive-publishers

The first two packages install components I need to write multilingual 
documents, and the last package installs some document classes (I need 
IEEEtran.cls specifically).

Looks like that’s provided by the texlive-latex-ucs package.

We are trying to improve the (modular) LaTeX situation, but it’s tricky
and we haven’t packaged enough things yet, partly because it’s not clear
what files in the TeX Live SVN tree really belong together.

For the time being you may even want to install the huge, monolithic
“texlive” package into your profile instead of relying on the minimal
fragments of TeX Live that are required to build LyX.

I installed "texlive"; problem solved :)


Thanks, Ricardo.

Not ideal, but I’m glad it’s working for you.  I hope we can soon
provide a better experience with the modular texlive.

About this issue, I get a lot of messages like this

frontends/qt4/GuiApplication.cpp (643): Cannot load icon 
/gnu/store/x9qb06kvbqd9l6521arvfbbk8m0s41r9-lyx-2.3.2-2/lyx2.3/share/lyx2.3/images/buffer-update.svgz 
please verify resource system!

when I run LyX from a terminal.

The lxqt package has this comment:

       ;; TODO: qtsvg is needed for lxqt apps to display icons. Maybe it
       ;; should be added to their propagated-inputs?
       ("qtsvg" ,qtsvg)

LyX is using Qt4 (why actually?), so this doesn’t directly apply, but I
guess the solution will be similar.

I installed "qtsvg" and LyX now displays icons normally when I launch it 
from a terminal. It still displays no icons when I launch it using GNOME 
Shell's Alt+F2, though.

I think this means that the executable needs to be wrapped in an
environment that provides qtsvg as the availability of qtsvg in the
launch environment appears to make the difference here.
