Compliling Lem on Arm - Librem 5 phone.

[aykaramba]

Hi.

I am trying to compile Lem on my Librem 5 phone that runs Debian 11. Quicklisp errors out with "lem-mailbox" not found. I don't understand this error, I do know there is some code in Lem that refers to it, but I don't understand why it is not being found.

Details:

Any suggestions on how to resolve this issue and move forward with the quickload process?

Thanks.

Hi, you can try:

cd ~/common-lisp git clone https://github.com/lem-project/lem-mailbox.git

Then (in sbcl): (ql:quickload :lem-mailbox)

https://lem-project.github.io/installation/ncurses/linux/#install-qlot Library dependencies are resolved using qlot, and we recommend using that method.

If you are running Debian, you can also try the automatic installer (which will install the system dependencies + qlot) https://lem-project.github.io/installation/ncurses/linux/#debianmintubuntu

Just dropping in to give everyone an update and perhaps help other noobs trying to install Lem on the Librem 5:

1. I wanted to install / compile all the components and Lem using Quicklisp. I think the issue was with the version of libffi and I could not figure out how to fix that manually.

2. As per everyones suggestion here, using Qlot to build the ncurses and sdl2 versions of Lem works! Summary:

** Install qlot Automatic installer: curl -L https://qlot.tech/installer | bash

** Download and build the executable Create the directories:

mkdir $HOME/common-lisp && cd $HOME/common-lisp git clone https://github.com/lem-project/lem.git cd lem && make ncurses

**To build the sdl2 version: make sdl2

Instructions as others poted: https://lem-project.github.io/installation/ncurses/linux/#debianmintubuntu

SUMMARY: Lem continues its conquest of platforms, now running on the Librem 5!

Thanks everyone for the amazing editor and the deep levels of help to resolve this issue. I will now learn how to use Qlot, that is amazing as well.
