Wuh. That's a bit complex. For distribution packages that depend on context for generation of PDF documents, having context as a system package is essential.
And, distribution maintainers can make things work if they understand TeX directory structure and texmfcnf.lua. It comes down to care. If they care and they have installation guide, they will make it work. ------- Original Message ------- On Sunday, August 21st, 2022 at 7:13 PM, Michal Vlasák <lahc...@gmail.com> wrote: > On Mon Aug 15, 2022 at 2:03 PM CEST, amano.kenji via ntg-context wrote: > > > TexLive has texmfcnf.lua that doesn't really work with texlive-context > > installed by linux distributions. > > > > Arch Linux has its own patched version of texmfcnf.lua. > > > > It seems I'd be better off with a linux package for ConTeXt LMTX. > > > > How can I build and install ConTeXt LMTX on Gentoo Linux or any linux > > distribution? > > > > I wish it was as simple as ./configure, make, and make install. > > > Some of the problems were mentioned in previous discussions.
