Reminder

• I agree that it's usually impossible for others to help me without my logs.

I believe this is not your problem, but this affects your project, badly. My main pc is currently broken thanks to this.

[developercrocodiles]

Arch on your main pc! :)

You can fix this! During the install, open a second terminal (change the commands below with your own user name and location):

Adding this here to flag the other users issue as well #3420

nano /home/nonasuomy/.cache/dots-hyprland/sdata/dist-arch/illogical-impulse-microtex-git/src/MicroTeX/src/platform/cairo/graphic_cairo.cpp

Add/change the top of the graphic_cairo.cpp file to look like this:

#include "config.h"

#include <fontconfig/fontconfig.h> // move this here

#include <fontconfig/fcfreetype.h> // add this

#if defined(BUILD_GTK) && !defined(MEM_CHECK)

#include "platform/cairo/graphic_cairo.h"

#include <utility>

using namespace tex;
using namespace std;

Compile

cd /home/nonasuomy/.cache/dots-hyprland/sdata/dist-arch/illogical-impulse-microtex-git/src/MicroTeX/build
      make

Install

cd /home/nonasuomy/.cache/dots-hyprland/sdata/dist-arch/illogical-impulse-microtex-git/
      makepkg -fsi --noextract

Go back to the other terminal...

You may need to resolve the problem manually BEFORE repeating this command.
[Tip] If a certain package is failing to install, try installing it separately in another terminal.
  r = Repeat this command (DEFAULT)
  e = Exit now
  i = Ignore this error and continue (your setup might not work correctly)
 [R/e/i]: 

Ignore the error in the other terminal with 'i' it will then resume without issue.

Enjoy!

Thank you so much!

Leaving this open as it is still an issue.

[gauravdhali]

same issue happened with me , i expect that developers will fix this issue asap

[NonaSuomy]

I don't expect it to be fixed very fast as it is an issue here:

dots-hyprland/sdata/dist-arch/illogical-impulse-microtex-git/PKGBUILD

The dev has not been active for over a year.

Thank you @NonaSuomy works for me

In such case I guess we need to fork https://github.com/NanoMichael/MicroTeX to make a fix on our own... @end-4 Could you please make a fork and invite me?

[wfogame]

Oh i recently had the same issue, i just skipped it, nothing bad happened.
