Hi Ricardo, LyX seems to build and run fine without this texlive-union. The texlive stuff is only required when one wants to compile a lyx document to a pdf. I'd therefore expect it to not be a dependency (but maybe a recommended package). And removing this texlive-union fixes my problem: Now, if texlive is installed in the profile, it finds it and all its components. (Note: I use "./pre-inst-env guix environment --pure --container --share=$XAUTHORITY --share=/tmp/.X11-unix --ad-hoc lyx bash coreutils evince -- env XAUTHORITY=$XAUTHORITY DISPLAY=$DISPLAY lyx2.3" to run lyx so that it reconfigures at startup) Xavier On Mon, Aug 12, 2019, at 9:30 PM, Ricardo Wurmus wrote: > > Hi Xavier, > > thanks for the report! > > > Since it loaded inputenc, the package just before refstyle, from > > /gnu/store/wy5865kh09qak63rpq3v47wnxv2gj1y0-texlive-union-49435/share/texmf-dist/tex/latex/base/inputenc.sty, > > and /gnu/store/wy5865kh09qak63rpq3v47wnxv2gj1y0-texlive-union-49435/ does not contain refstyle, I > > think that the problem is that LyX uses the pdflatex from this > > textlive-union instead of the one from the full texlive. > > The problem is that Lyx is configured to use the texlive-union that was > provided during the build.
