Hello Michal,

Can you jdh or anyone with a similar setup try to run the following two
binaries? Run with '--help' only, other than that not much works.

https://github.com/vlasakm/mmtex/releases/download/cross-test/ltex-aarch64-linux-gnu.2.28
https://github.com/vlasakm/mmtex/releases/download/cross-test/ltex-aarch64-linux-musl

If I didn't mistake the architecture, these should work. At least I can
confirm that the second (fully statically linked) one works on my x86_64
linux with:

chmod +x ./ltex-aarch64-linux-musl
qemu-aarch64 ./ltex-aarch64-linux-musl --help

The above are cross compiled (debug) builds of very stripped down
version of LuaTeX, that I have been experimenting with. They won't solve
the immediate problem, but the cross compiling procedure could be used
to generate luametatex binaries for this target until a better option is
available. Of course, depending on whether it even works. :)

We need to set up an older linux distro for building 64-bit binaries

There is no Harvard bibliography specification, but the system is 
designed to be totally configurable.


What is exactly the specification? The best way to proceed is to start 
from an existing specification such as APA for an author-years system 
and adapt it to your specific needs. I can help you with this.

Re: [NTG-context] mp-geo Metapost package with ConTeXt

Hi Hans, Aditya, and all,

Me:
 I’d like to use the mp-geo Metapost package with ConTeXt to draw simple

https://melusine.eu.org/syracuse/poulecl/mp-geo/ 
 

Aditya:

Hans:

This is great fun! I slightly altered Hans’ code to produce the most basic area 
preserving projection of North America (code and map below). If anyone else is 
playing with the mp-geo data, it is in arc minutes, so divide by 60 to get 
degrees.

For my book I only want 5cm diameter globes with continents, so the map data in 
the mp-geo package is far more detailed than I need. The code is so fast, the 
detail doesn’t seem to be a problem.

I just started learning Metapost a month ago, and it’s great. I know almost 
nothing about Lua, but this looks like a fun project for learning more!

Thanks!
Gavin

It is good practice to mention your platform in problem reports.   For this
error, your best source of
help will be RPi and OS forums.   Once you find a solution it may help
others to post the details (including
the forum that provided the solution) here.
