Re: [Texmacs-dev] AppImage, another try

[Alvaro Tejero Cantero]

Ubuntu 20.10

* made executable, run, loaded an example document -> this works

* searching in the help works

* but trying to export to pdf (my own document, document from help) bails out with the following error (here sharing only console messages after all the usual "approximating font tuple" warnings

TeXmacs] With linked TrueType support

PS. Here like when using the .deb package the UI looks ugly due to small icons and too big menu fonts. I am running TeXmacs in 4K with 2x scaling under GNOME - I suppose I should tweak a QT setting to rescale the menu fonts?

Dear all,
 I'm slowly trying to understand the process of creating an appimage. My current attempt it is this:


https://www.dropbox.com/s/2vlfusrrsmqcnvv/GNU_TeXmacs-0512ee9-x86_64.AppImage?dl=0

Can you give it a try on your Linux box?

It works on the two machines I have access to.

Note that it is quite large (100MB) because essentially I include all the libraries needed, down to libc. If it works I will try to streamline the dependencies.

My goal is to have an exectutable which will work on any Linux Box. It shuld also work on FreeBSD, for example.

Best
Max
