Subject: [PATCH core-updates-frozen v3] gnu: texlive-texmf: Disable LuaJIT
 engines on powerpc64le
Date: Thu, 19 Aug 2021 21:47:15 -0300

LuaJIT isn’t ported to 64-bit PowerPC. ‘texlive-bin’ and
‘texlive-latex-base’ already disable the engines that rely on it, so just
do the same in texlive-texmf.

Fix suggested by Mathieu Othacehe <othacehe <at> gnu.org>.

Also, for consistency use ‘target-ppc64le’ in ‘texlive-bin’ as well.

* gnu/packages/tex.scm (texlive-bin)[arguments]<#:configure-flags>: Use
‘target-ppc64le’.
(texlive-texmf)[arguments]<#:phases>{texmf-config}:
Disable LuaJIT engines when building for powerpc64le.
---

Hello,

This fixes the build of ‘texlive-texmf’ on powerpc64le. It was failing
with these errors:

  fmtutil [ERROR]: not building luajittex due to missing engine: luajittex
  fmtutil [ERROR]: not building luajithbtex due to missing engine: luajithbtex

Thank you very much to Mathieu for his help in making  this work.

Changes since v2:
- Use ‘target-ppc64le?’ to match target string.
- Change ‘texlive-bin’ to also use ‘target-ppc64le?’.

Changes since v1:
- Match target with “powerpc64” prefix rather than “powerpc64le”.
