Attempting my first build - Notepadqq

snapcraft

Hello,
M
I am having a problem with my first build. I did search the forums & reference website to no avail.

Here is the (hopefully) relevant part. Please let me know if anything else is needed.

Thanks!

you don’t need these for the make plugin, as the plugin handles calling those two commands itself. If you did want to override the plugin then you need to alter your make install to tell it where you want to install your files to (i.e. into the snap):

make DESTDIR=$SNAPCRAFT_PART_INSTALL install

Looking through the repository for notepadqq it looks like you really want to be using the autotools plugin instead of the make plugin, which will handle running any configure script or autogen.sh script present (the notepadqq has a configure script).

Thanks Daniel. I changed it to autotools and it went further, but I am getting a different error message now. Any ideas with this? I tried a couple of different options I found but same error each time.

I’ve done some investigation, and it seems the configflags need to be altered to get the files in the right place (this build is actually not autotools-based like I told you, but seems to be a qmake project with a weird hybrid wrapper script which causes inconsistencies with how we expect things to work in the snap world):

parts:
  my-part:
    ...
    configflags:
      - --prefix=$SNAPCRAFT_PART_INSTALL/usr

Normally we’d rely on make with the DESTDIR override by snapcraft to get the files into $SNAPCRAFT_PART_INSTALL but it seems that the Makefile created by notepadqq’s configure script doesn’t respect that variable so the --prefix needs altering to fix it - hopefully notepadqq doesn’t save any paths into it’s binary files during the build - some apps do that which causes us no-end of trouble relocating them via snaps.

Thank you again Daniel. It is running now, with just a few remaining messages:

Qt: Session management error: None of the authentication protocols specified are supported

Missing icon: “go-previous”
Missing icon: “go-next”

I would appreciate anyone who wants to test it. Thanks!

That one seems to be innocuous (not a problem). I’ve seen it on several snaps and can’t find any way of squashing it or even what the actual problem is…
