Hello Guix,
I would like to ask for help with a couple of issues that I ran into while
trying to fix a build failure in ‘texlive-texmf’ in the core-updates-frozen
branch on powerpc64le-linux:
fmtutil [ERROR]: not building luajittex due to missing engine: luajittex
fmtutil [ERROR]: not building luajithbtex due to missing engine: luajithbtex
The problem is straightforward: LuaJIT isn’t supported on powerpc64le.
‘texlive-latex-base’ disables these engines accordingly:
;; LuaJIT is not ported to powerpc64le* yet.
,@(if (string-prefix? "powerpc64le"
(or (%current-target-system)
(%current-system)))
'("luajittex" "luajithbtex" "mfluajit") '())
So all I have to do is disable these “*luajit*” engines in ‘texlive-texmf’
as well. Unfortunately copying the same ‘if’ expression like so:

So this is my first question: why does that ‘if’ condition work in
‘texlive-latex-base’ but not in ‘texlive-texmf’? I can’t see a significant
difference between the two.
In any case, I thought I could solve this by using a gexp. I tried several
different variations, but none worked. I think this was my best shot:

So my second question is: can somebody see any way to make ‘texlive-mf’
disable the “*luajit*’ engines when building for powerpc64le?
