Puppy Linux Discussion Forum

these are portabilized packages I made with CDE

1. qcomicbook

https://www.dropbox.com/s/cvw4fsa4ytf3q ... ar.xz?dl=1

a light qt3 cbz/cbr comic viewer that I used in puppy 3.01

you need to go in

cde-root/tmp/qcomicbook.cde

and click on .cde script. I don't have idea to avoid this every time, if you know how to make a shortcut to cde script, I'll be pleased

I didn't test as I'm not on 32-bit atm, but I'd say it should work a script directly in cde-qcomicbook dir containing:

EDIT: Previous code didn't work, tested now and this works for me:

#!/bin/sh

HERE="$(dirname "$(readlink -f "${0}")")"

cd "$HERE/cde-root" && "$HERE/cde-exec" "tmp/qcomicbook" "$@"

This way, when creating (somewhere) a symlink to this script , it should work too.

@Dingo :-

Heh. That's a surprise..!

I downloaded this to take a look. I take it this is normally installed manually, yes? (It's not a .pet or SFS.) Ah, no, of course; this is similar to other self-contained apps, isn't it.....everything running from within its own directory. Hmm...

In Fossapup64 - with the 32-bit_compat_libs SFS loaded - I just ran qcomicbook.cde from the terminal, out of curiosity, to see what happened. Damn me if it didn't fire straight up, without the need to install anything else....

Whether or not it will actually function, and do what it's supposed to, I don't know; I don't really know what you're supposed to do with it, TBH.

But that's not bad for backwards compatibility, is it? Something built for Puppy 3, running quite happily under Puppy 9...!

What DO you use this for?

Mike.

@mikewalsh

I use this comic book viewer for images packages into a . zip or .far Archive with cbz and CBR extensions

I was in love with puppy 3.01 since 2007 to 2016, with same savefile and hypercustomized my puppy version compiling tons of terminal and GUI apps. There are many light apps I miss in modern puppies that I try to portabilize with CDE, since without all these tools I compiled for me in all these years, I'm feeling like a kid who lost his closer friends

CDE is no more downloadable on project page, but this is the 32 bit binary I had

download/file.php?id=2300

There are some oddities with CDE, like the fact that everything is "jailed" in CDE-root directory. For instance, if you make portable a graphic application with CDE, it's file-picker cannot open files outside the CDE-root directory. You need to copy, move or (maybe) symlink files you want open in CDE-root directory

@Dingo :-

A-ha. In other words, it's like a chroot.

I tried Fred's suggestion, above, y'see. Created a script called 'LAUNCH', inside 'qcomicbook', and alongside 'cde-root', then added Fred's code above.....and this is what I got:-

root# ./LAUNCH
ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.
Error: cde-exec must be run within a cde-root/ directory
root#

Ignore the first part.....that's only because I'm running it in a 64-bit Pup with 32-bit compat libs loaded. It's that's last line we're interested in, of course:-

Error: cde-exec must be run within a cde-root/ directory

.....which immediately makes no sense, because if that's the case, why does the cde-exec binary sit outside cde-root? Uh.....ah; I guess that means it has to be called from within cde-root. Hmm....o-kayyy.

So; you need something LIKE a chroot script to start it 'externally'......except a 'true' chroot script won't work. And interestingly, you can start this by directly clicking the script inside the cde-root 'jail'. You can't do this with a proper chroot 'jail'; that HAS to be started externally (from the 'host' Puppy).

I'm at a loss to understand quite how this does fire-up.....

@fredx181 :-

Any ideas here?

Mike.

Make it a RoxApp.

Mm-hm. Yeah, that would make more sense; Fred's scripts will do that for you, as a by-product of creating an AppImage or self-extracting script.....

Hi Mike, I tested now and found after some tries that this works:

#!/bin/sh

HERE="$(dirname "$(readlink -f "${0}")")"

cd "$HERE/cde-root" && "$HERE/cde-exec" "tmp/qcomicbook" "$@"

This way by cd'ing to cde-root first, cde-exec runs from within cde-root as it's apparently supposed to be.

Edited my previous post.

@fredx181 :-

Yah, that works nicely. Now, why didn't I think of that..? (D'oh.....!!)

Mike.

@Dingo :-

There ya go. Fred's modified script, above, works nicely. I've used it in the following way, to make it a bit easier still....

• 1) Create a new directory; call it "QComicBook-portable".

• 2) Place the entire "cde-qcomicbook" directory inside that.

• 3) Create a new script beside it. Call it "LAUNCH", and put the following inside it:-

#!/bin/sh

HERE="$(dirname "$(readlink -f "${0}")")"

cd "$HERE/cde-qcomicbook/cde-root" && "$HERE/cde-qcomicbook/cde-exec" "tmp/qcomicbook" "$@"

Finally, tart it up by putting the attached PNG icon inside the "QComicBook-portable" directory, and re-naming it to ".DirIcon" (nothing else; lose the .png extension, as well). Don't worry about the size; ROX automatically re-sizes icons for the pinboard.

What I tried and works is creating a symlink to /mnt in cde-root, to be able to browse mounted partitions in /mnt.

@fredx181 @mikewalsh wow! It seems very promising! I'll make other packages with CDE. There are many apps I miss in modern puppies that I'm unable to compile with newer gcc due to source code incompatibilities

Hi.

In 2014 I was already experimenting with CDE packages.
At these days I created a RoxApp for the CDE packager to easily create CDE packages.

@Dingo :-

It's just a variation on how I package a lot of the portables. I got into the habit of using that clearly marked "LAUNCH" script some time ago; makes it easier - especially for beginners - to fire things up instead of digging around inside the main app directory to find a specific script to start 'em.

But the "readlink 'trick'":-

HERE="$(dirname "$(readlink -f "$0")")"

....that's the bit of code that's basically made all my portables possible. And I have Fred to thank for that; either digging it out from somewhere, or coming up with it himself (though I'm pretty sure that's been floating around the web in one form or another for a long time, 'cos I think I've spotted it myself a few times.)

If you build any others, you ought to be able to "modify" the set-up for this one to work with others, too. It's not hard.....just needs a bit of careful editing, that's all.

Mike.

Fred:-

That's similar to what I do with the browsers and various other apps I run from my chroot Puppies. They have to download/upload from within the chroot, so I've created a directory in the chroot Puppy's /root called 'MEDIA', then created Downloads & Uploads inside that.

The chroot's 'MEDIA' directory is then simply sym-linked into the 'host' Puppy's /root directory, for easy access. And I use 'Copyfast' to just move stuff in there when I'm uploading stuff to the Drive, or for here on the forum, or image-hosting.....whatever. Works well.

Mike.

Hurrah! Yippee! I just packaged with cde several other applications I'll post in this thread in my first message

sodipodi 0.34 (the good old 32 bit sodipodi it is not possible compile with modern gcc) is now running on xenialpup64 very fine, alongside with epdfview and gsview

@Dingo
I think your cde version is rather old, I compared and had better results with a newer version, here it is, cde.tar.gz (32 bit):

Please Don't.
Don't get me wrong. I'm glad your back and contributing, indeed contributing both interesting ideas and packages. But I started "AppImages, Snaps and Flatpaks" as soon as I could when this became Puppy's principal meeting place. It started as a 'thread' and has since become a 'Sub-sub-Forum'. In my first post I wrote:
"Please ONLY add to this thread other repositories; general information about AppImages, Snaps and Flatpaks, techniques for working with them and corrections of any mistakes in this thread,
To assist anyone looking for a particular application or type of application, please discuss specific applications under the Software Section discussing that specific type of application.

I know others have not honored that plea. But there is method to my madness. Have you ever tried to find some application? Even one about which you posted? Unless there's some recognizable structure to the Forum, it's almost impossible. If you're looking for an application, the most likely place to find it will be in the Additional Software Sub-Forum which holds the treads of that specific type of application.

By the way, your initial post about CDE belongs here. It's another method of packaging, not mentioned in the title because I didn't know about it. And now that it's been 'rediscovered', should prove both interesting and useful.

Ok. Should I post the packages I made portable with CDE in separated software section, right?

@fredx181 thanks. What do mean, exactly, with "better results"?

On second thought I must say that I don't really know, probably it depends on the program you make a cde-package from.
I was experimenting with making a cde-package for a Wine program and found that the newer version does accept at the command line e.g. env WINEPREFIX=... where the older version doesn't.

Right. Ordinarily, I would have suggested that sodipodi 0.34 be published here, viewforum.php?f=103 "Advanced Topics>Additional Software (PETs, n' stuff)> Graphics" with other graphics applications.
But your posts have been our re-introduction to CDE. Going into detail about employing CDE in order to run a specific application serves as a good way to explain the concept. And particularly valuable was your report that "sodipodi 0.34 (the good old 32 bit sodipodi it is not possible compile with modern gcc) is now running on xenialpup64 very fine." Emphasis supplied. That told us how useful CDE may can be in general which stimulates thinking about 'How can I put this to use?'

I made a note on my 'ToDo List' to explore CDE further. And today I see that fredx181 has already beaten me to exploring the particular area my initial thought about where CDE could be particularly valuable: Wine and the possibility of running it in a container.
