Laboratoire ICAR » Plateforme TXM

The annotation bar cannot be opened when TXM 0.8.1 + URS is installed on fresh Ubuntu 20.04 machine

The error is asynchronous and some times the toolbar opens

A JS function failed with the following error message:

Solution 1¶

Fix the JS function -> When using WEBKIT the javascript code is executed within a temporary&uniq JS function thus

function test() {...}

code alike won't be accessible afterward

Solution use the

test = function test() {...}

pattern
h3. Solution 2

backtrack to GTK2 but one must install libwebkitgtk 1.0.0 manually and its dependencies

mkdir txm_deps
cd txm_deps
wget http://ftp.de.debian.org/debian/pool/main/w/webkitgtk/libwebkitgtk-1.0-0_2.4.11-3_amd64.deb
wget http://ftp.de.debian.org/debian/pool/main/m/mesa/libegl1-mesa_18.3.6-2+deb10u1_amd64.deb
wget http://ftp.de.debian.org/debian/pool/main/w/webkitgtk/libegl1-x11.deb
wget http://ftp.de.debian.org/debian/pool/main/e/enchant/libenchant1c2a_1.6.0-11.1+b1_amd64.deb

sudo dpkg -i *.deb

Patch "/usr/bin/TXM-0.8.1" to run TXM with GTK2 :
