exe-thumbnailer.thumbnailer keeps failing to generate thumbnails
Closed this issue · 3 comments
I'm on Fedora 36, and I've placed exe-thumbnailer.thumbnailer
into /usr/local/share/thumbnailers/
, but it keeps failing to generate icons for my EXE files. They always end up as a 1x1 PNG image in the fail
directory.
icoextract
and icolist
themselves work just fine and output correct PNG images.
Any idea what's wrong?
UPDATE: Turns out you have to install it as root or use a virtual environment.
Hi,
Installing as root shouldn't be strictly required; what's needed is access to the dependencies (pefile and pillow). These are fairly common and you should find them in most distro repositories.
Also, you should see a more obvious error if you try running exe-thumbnailer
from the command line:
usage: exe-thumbnailer [-h] [-V] [-s SIZE] [-v] inputfile [outfile]
Linux (freedesktop.org) thumbnailer for Windows PE files (.exe/.dll)
positional arguments:
inputfile input file name
outfile output file name
options:
-h, --help show this help message and exit
-V, --version show program's version number and exit
-s SIZE, --size SIZE size of desired thumbnail
-v, --verbose enables debug logging
Pefile and Pillow are both installed, and exe-thumbnailer
does not spit out any error, and works when I manually run it from the terminal.
It's just when Nautilus/GNOME tries to run it for thumbnail generation that it "bugs out" and generates that 1x1 pixel PNG.
I'm guessing since the thumbnailer is located at /usr/local/share/thumbnailers/
(root) it also tries to look for icoextract
and icolist
at root, which does not exist.
So perhaps placing the thumbnailer locally at ~/.local/share/thumbnailers/
might work?
But running sudo pip3 install icoextract[thumbnailer]
installs icoextract
and icolist
at root, so for now that's what I'm sticking with.
Next time I setup a VM I'll explore this further.
Yes, ~/.local/share/thumbnailers/
will be better if you're installing locally (per user). I'll make the description more clear
