[Arch Linux] DiE 3.11+ detects known file types as "Unknown"

[ClosedPort22]

This issue only affects DiE 3.11 and above on Arch Linux.

Steps to reproduce:

1. Install the GitHub release of DiE via pacman: sudo pacman -U https://github.com/horsicq/DIE-engine/releases/download/Beta/detect-it-easy-3.20-1-x86_64.pkg.tar.zst

2. Open any known file with DiE, e.g. a plain text file

3. Notice that DiE detects the file type as "Unknown"

This happens because starting from 3.11, DiE searches for signatures, etc. in /usr/lib/die/ instead of $data (whatever that means). If you go to Options > Scan and replace all occurrences of /usr/lib/die/ with /opt/detect-it-easy/, then DiE will work normally again. However, there don't seem to be options for customizing the locations of QSS and language files, so these features are still broken.

I am honestly surprised that no one seems to have reported this anywhere yet, but I don't think it's specific to my setup. In any case, if someone is facing the same problem as I am and has stumbled upon this issue, you can fix it by simply symlinking all subdirectories in /opt/detect-it-easy/ into /usr/lib/die/. Here's a PKGBUILD that does just that:

pkgname=detect-it-easy-directory-fix
pkgver=1
pkgrel=1
pkgdesc='Fix directory layout of Detect It Easy 3.11+'
arch=('any')
url='https://github.com/horsicq/Detect-It-Easy/issues/333'
license=('0BSD')
depends=('detect-it-easy>3.10')

package() {
  mkdir -p "$pkgdir/usr/lib/die/"
  for dir in {db,images,info,lang,qss,signatures,yara_rules}; do
    ln -s "/opt/detect-it-easy/$dir" "$pkgdir/usr/lib/die/$dir"
  done
}

Of course, this can also be fixed by repackaging the .pkg.tar.zst file.

Thanks for the report! It will be fixed!
