Error "while loading shared libraries" with BloodHound snap

snap

I’m trying to build a snap for BloodHound (the single page Javascript web application part). Here is the current snapcraft.yaml:

    after: [desktop-gtk2]

The build goes OK, but when I install the snap and try to launch it, I get this error:

$ bloodhound.bloodhound-app 
/snap/bloodhound/x2/BloodHound-linux-x64/BloodHound: error while loading shared libraries: libXtst.so.6: cannot open shared object file: No such file or directory

The thing is that I also tried to build it with:

    after: [desktop-gtk3]

And then the error was:

 $ bloodhound.bloodhound-app 
/snap/bloodhound/x1/BloodHound-linux-x64/BloodHound: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory

And it both cases the application starts if I execute it directly:

$ /snap/bloodhound/x1/BloodHound-linux-x64/BloodHound

So I’m kind of lost…any ideas? Should I be using the gnome-3-26-16-04 part or something?

nobody? I’m still stuck with this…Thanks!

You have to specify to stage the files installed via stage-packages as well:

    filesets:
      files-from-stage-packages-excluding-docs:
      - usr/*
      - -usr/share/doc/*
    stage:
    - $files-from-stage-packages-excluding-docs

Snapcraft by default stage nothing.

4

that’s not entirely accurate… Snapcraft will by default stage everything that you have “installed”. Installing means that you have created or copied files in $SNAPCRAFT_PART_INSTALL. Everything in $SNAPCRAFT_PART_INSTALL will be staged and subsequently primed unless removed by the stage or prime file sets.

5

This is your problem with being unable to find the libraries. This stage block is saying to remove everything except the BloodHound-linux-x64 file or directory. That means it will remove the usr/lib directory from this part when building your final snap.

6

Thanks for the correction, I assume this is the behavior when the stage keyword is omitted right? I mean does it still stage everything when stage keyword is used but not explicitly enumerating everything in the installtree?

  • The behaviour is to stage everything when the stage keyword is omitted.
  • When the stage keyword only includes negative entries then everything except those listed will be staged.
  • When at least one positive entry is listed everything is removed from the staging except the positive listed items.

stage everything except the file or directory called “negative”

stage:
- '-negative'

only stage the file or directory called “positive”

stage:
- positive

Wanted to try this, but now is not even compiling; it errors with:

npm ERR! peer dep missing: ajv@^6.0.0, required by ajv-keywords@3.2.0
Failed to run 'npm ls --global --json' for 'bloodhound-app': Exited with code 1.
Verify that the part is using the correct parameters and try again.

But even installing ajv in the node-packages property does not helps…

I’m having this same issue but with libX11.so.6. Running from the normal command-line (snap) doesn’t work but running directly does.
