Where is `gs` (ghostscript)?

snapcraft

Hi ! @Snapcrafters .

I shipped ghostscript in my snap package (pdf-tool), but I can’t find it (at least with the keyword gs or ghostscript).

Thanks for your help.

Can you provide more details on what you mean by “shipped”?

A snapcraft.yaml would be useful too.

Hi ! @mr_cal .

Put it in the stage-packages .

4

And you want to be able to execute Ghostscript at runtime (when the snap has been installed)?

5

In my snap app.

ghostscript is a dependency .

6

You could try entering the environment with snap run --shell pdf-tool and finding the Ghostscript executable. Then, you could append its directory to the PATH environment variable in your snapcraft.yaml.

7

I have already tried this scenario.

Maybe the program name in the snap is different than the one used by default on Linux.

8 
$ ls -l /usr/bin/ghostscript 
lrwxrwxrwx 1 root root 2 Dec 11 19:22 /usr/bin/ghostscript -> gs
 $ ls -l /usr/bin/gs
-rwxr-xr-x 1 root root 14488 Dec 11 19:22 /usr/bin/gs
 $ dpkg -S /usr/bin/gs
ghostscript: /usr/bin/gs

It’s in the deb, but way better to share slightly more than one line of a snapcraft.yaml to be able to help.

gs or ghostscript does not work in my snap.

Yes, in the stage-packages entry, the correct word is ghostscript, but whether it is gs or ghostscript, both commands are not found in my snap package.

10

Yes, I understood that from your first post.

Please can you post the yaml?

Yea… .

Ok, can you please show the output of you running whatever it is that’s not working. Please don’t trim the output. Just run whatever it is you expect to find ghostscript or gs.

@popey ! This log is of no use for the topic in question, I know perfectly well what it means. :slightly_smiling_face:

14

Ok, bye then. I’ve already wasted enough time trying to get blood from this stone. I’ll let you figure it out :wave:

15

@poyey !

Thank you very much for your intervention :slightly_smiling_face:.

I will create an algorithm which will allow me to find the gs(whatever the name) program among the packages embedded in my snap program.
