[main]Notes on TeXmacs

Compiling TeXmacs on Ubuntu 22 with Guile3 and Qt5

This guide describes how to compile TeXmacs on Ubuntu 22 with Guile 3 support and Qt 5.

Guile 1.8.8 is no longer supported on modern distributions. Let us build the Guile3 scheme TeXmacs fork.

1.Dependencies

You need git to download the sources, cmake and g++ to compile them and Guile 3, Qt 5 and freetype as dependencies.

sudo apt install git cmake g++ guile-3.0 guile-3.0-dev libfreetype-dev 
sudo apt install qtbase5-dev libqt5svg5-dev libfreetype-dev libsqlite-dev libjpeg-dev 
sudo apt install libgmp-dev libltdl-dev

2.Compiling

Navigate to the directory where you want TeXmacs' sources to be placed in.

Clone the TeXmacs git repository and navigate into it.

git clone https://github.com/texmacs/texmacs.git texmacs-guile3

cd  texmacs-guile3

Checkout the Guile 3 branch.

git checkout guile3_branch_2.1

Run the configure command (the first dashes are double dashes – it is just weird HTML rendering <dash><dash>with<dash>guile2 etc.).

./configure –with-guile2 –enable-guile2

Compile TeXmacs.

make -j4

The TeXmacs binary is placed in <repodirectory>/TeXmacs/bin/texmacs

3.Running

To run TeXmacs you have to setup the TEXMACS_PATH variable. Run

export TEXMACS_PATH=<repodirectory>/TeXmacs

then you can run

<repodirectory>/TeXmacs/bin/texmacs

and TeXmacs should start after it compiled its modules. To make TEXMACS_PATH setting persistent, put the command:

export TEXMACS_PATH=<repodirectory>/TeXmacs

into your ~/.bashrc.
