Binary needs to be started from 'appdir' directory...

[HaleTom]

As background for the desire for a binary package:

• I want to save user's time in compiling
• Provide access to the skeleton config file
• Provide access to the documentation

Both of the last two are difficult using the AppImage format, and the AppImage also contains many non-needed libraries (newer versions of which Arch already has)

[robert7]

Hi,
I understand what you want to do, but I think it is not the "correct" way. Therefore you'll get various unnecessary problems..

The Idea of AppImage is:

• the application in AppImage packaging is "self contained" - it contains all the dependencies in a coherent set - which plays together well
• yes its bigger then native package, but I think the people today don't care so much whenever the app is 50MB or 3MB. They care more whenever it works out of the box.
• yes it may be, that some libraries included in the AppImage are older then on your system, but the someway guaranteed to work
• the AppImage should work on ~all distributions and it should be really "plug&play" - download/mark as executable - run - it should work

As you start replacing libraries by LD_LIBRARY_PATH and removing parts of the AppImage this all may break..
I think correct way would be to build a binary package for your distribution. I have no idea how this work on Arch - and have no time to study it now. But the idea would be to do something like the pre-built binary "deb" packages, which are build in the PPA for Ubuntu - one package per Ubuntu version.

With that being said, what you want to do, can be reached (but I think you'll get further problems along the way.. so the problems only start :) )..

The error message you get happens when Nixnote is searching for application data. It expects to be run as $SOMEDIR/bin/nixnote2 then it searches for the data in $SOMEDIR/share/nixnote2. Thats all. The algorithm can be overriden by --programDataDir command line option.

Example (2 executions one failed - then one with manual override):

I improved the error message. Now it says:

[robert7]

The updated message is available in 2.0.1-beta5a (but its just a clue/info ).
Let me know in case "--programDataDir" did not worked for you.

[HaleTom]

Brilliant, thanks for the --programDataDir tip. I'll look into it over the next few days!

[HaleTom]

I downloaded today's AppImage and tried with a bunch of possible options to --programDataDir:

Note, all of the above directories exist (they were entered by tab-expansion).

Perhaps it's the code that checks for the existence of the given directory?

[HaleTom]

In the message, is SOMEDIR the root of the place it's being run from?

What is PROJECT_DIR?

[robert7]

$SOMEDIR is the "install prefix". If you unpack the AppImage into /home/ravi/code/aur/nixnote2-bin/squashfs-root then it its /home/ravi/code/aur/nixnote2-bin/squashfs-root/usr.
Then if you run /home/ravi/code/aur/nixnote2-bin/squashfs-root/usr/bin/nixnote2 then it should find the data by itself as it should be in /home/ravi/code/aur/nixnote2-bin/squashfs-root/usr/share/nixnote2.

Or you can say nixnote2 --programDataDir /home/ravi/code/aur/nixnote2-bin/squashfs-root/usr/share/nixnote2.

$PROJECT_DIR is the "project directory" - where you checkout the project from git, then its get per default installed in $PROJECT_DIR/appdir and $SOMEDIR would be $PnixnROJECT_DIR/appdir/usr.

simple case with appimage

here data is NOT relocated, but I point to data dir manually

example where you compiled & installed to default location

here finaly example where binary is in non standard path but I point manually to data

[robert7]

--programDataDirneed to be a path with following files:

[HaleTom]

Thanks for the examples!

I worked out it was a syntax thing...

--programDataDir /d/dev/nixnote2/appdir/usr/share/nixnote2 doesn't work

--programDataDir=/d/dev/nixnote2/appdir/usr/share/nixnote2 does work

The = is mandatory but no warning is printed if it is not given.

[robert7]

The = is mandatory but no warning is printed if it is not given.

yes. that's true.
