Hello,
Please, could tell me where to find a guide to how to package my applications (developed in Gambas) as Appimage.
The following guide from Appimage don't help me to package a Gambas application as Appimage package.
Packaging Guide - AppImage documentation
Any help will be much appreciate.

 Hi Philippe734 and welcome to the forum.

I had a quick look at Appimage as I had not seen it before. I'll be honest and say I have no idea how to solve your problem but if you could explain your intentions we may be able to offer another solution, for example if you are looking for an easy way to update your program on a remote computer or…..

 My goal is to share my applications as Appimage. As my applications are small, no need to do update in time, that's why I think Appimage is a ideal package type for share my apps.

 I see the point.
AppImage, makes it possible to share an App without the need to install other dependencies.
Problem is that you need to know way too many things in order to make it run.
Most frequent issues here, are DE incompatibilities.
On some distros, the same installation work flawlessly while on some others, installing Gambas might fail. It happened already many times.
If there were a packager capable to build a package as AppImage, this would make the Gambas Apps, distro agnostic which, I guess, is exactly the point of the topic.
So, is there any available choice?
Can we get to some result with this?
It would be beneficial for many Apps and for Gambas, as programming environnement.
For instance:
I packed DirLister and installed on the same computer I developped it. Worked flawlessly.
My DE is XFCE, on Linux Lite 4.8.
I moved to the other computer, where I have Linux Mint 19.3, also XFCE.
I had trouble installing the same package… Why did it happen, difficult to guess…
Maybe, Gambas installation somewhere was flawed, because later, after deleting everything and reinstalling Gambas, it worked.
The idea is that it would be far better without forcing the user to install Gambas, just to run an application. Makes sense to me.
As for me, it's of less interest if some MBs are occupied by Gambas. For some others though, might look like a great trrouble.

 Serban I agree with you.  Even if you install Gambas on some one's computer there are still problems with how the program looks.  I run Arch XFCE and programs I create look good and run good.  While a friend runs Xubutu there are problems with the way the program even looks.  I normally have to do some modifications to the program to make it look any where near how the program was designed.  While the code runs without problems the way the program looks changes.  Also I noticed that even some of the programs on the farm will not run on my version of Gambas because of QT4 libraries are no longer supported.  If I try to put in the QT4/QT5 switcher or GTK3 the IDE crashes.  So it's not the fault of Gambas 99% of the time but rather the non conformity of Linux from OS to OS, and Desktop to Desktop.

My takeaway from this thread is that Gambas is for personal use only.

 Actually  grayghost4 it works rather well for programming for others.  You just have to keep in mind that there are differences between the way the different versions of Linux handles the programs.  Some versions use GTK as the basis for graphical interfaces while other use either QT4 or QT5.  On my friends machine his version of Linux still uses QT4 for graphical interfaces and thus still has support for QT4 in Gambas.  In most cases I only need to switch to the version of QT that his system uses.  Some times I will have to go into the program itself and do some color changes.  It's basically the same with some of the programs available on the farm.  How ever like I said a few of the farm programs require QT4 which my version of Linux no longer supports.  This can be problematic but not unsolvable.

Appimage: Can we give it a try?

While my knowledge might be way behind the requirements of making it possible, the "<COLOR color="#0000BF">Fail - Learn - Succeed</COLOR>" approach, looks far better to me than "I'm too small for this big war" paradigm.
Assuming we'll fail. So, what? Will that be deadly?

Here is the start point:
Packaging Guide - AppImage documentation

Question is:
<COLOR color="#0000BF">What if it works?</COLOR>

Not sure if it'd be possible.
The gambas application says we compile a stand-alone app but it's not really.
Still gonna need the gambas-runtime installed to run it and the components like gb.form and gb.image as well.
Like a Windows .net app , it's not going to run without the .net runtime stuff installed in the system.

I'm currently making a project called GambasMan.
I select one of my project folders and it gives some options like compiling the exe into a different dir as any name (without .gambas extension if you want)

Another more relevant function it has is a "minimum requirement installer"  
This makes a simple bash script that'll run apt-get install (or yumi) and install just the gambas-runtime for the user plus the components required by the app.
Simple i should think for most users to use okay.
(i just need to figure out how to add the gambas filetype to the system to negate the need to use the gbr3 prefix)
Just the runtime and the components is a relatively small/quick install too.

As for the look on different machines i've also noticed this and think all it needs is a bit more coding/thinking when it comes to object sizing,  Ie. setting object dimensions at runtime before the form loads using the object.Font.TextWidth and TextHeight functions. I think it's safe to consider making an object that's size looks okay on your machine may not look the same on another machine.  Various objects have an .AutoResize switch that helps (shame they don't all have it)

Only OS's i got to try it on though at mo are Debian, Mint (both MATE), and Raspbian (not sure what it is, lxde or xfce4), , might set up some more.

I'll have a look at AppImage though and see what i can figure out

I had a look and found if i went to the appImage website and downloaded their AppImage maker , that was an AppImage , it didn't work lol.
It's not looking promising lol.

I've made this…
(attachment removed)

It's some code i've ripped out of one of my other apps.

it asks for your gambas project directory and reads the .project file in it and gets your apps required gambas components.

It then makes a simple bash script to ask to install the minimum required stuff in the project folder or another of your choosing.
searches for apt-get yum and dnf

the script is set up in a way that it passes the components required through the GetFormat() routine (this is in case we need to change the '-' separator to a '.' or something ie. gambas3-gb-form or gambas3.gb.form as i think some distros use a different way)
the app uses the gambas3-gb-form syntax for apt yum and dnf

PS, it's compiled on Gambas 3.15 , if your gambas is older you can just load it up and recompile.

Testing it, Bruce, thanks for sharing. Will post feedback afterwards.

somebody HAS made an app image.
search the gambas m/l for appimage.

 Maybe I am doing something wrong, but the GambasAppInstallMaker did not solved the problem. It gathered the depdndencies, and created the .sh witch I run via sudo at a terminal with no errors. Then the Software manager installed the deb, but there was a conflict between gb versions:
-the SH installed 3.15.2,
-deb needed 3.16 (stable PPA)

, so my app couldn't run. I will investigate AppMain or other options.
Thanks anyway.

 the installer does not install any particular version, the version it installs depends on how you have apt set up.

if you need the ppa stable version you have to add the ppa to your apt and run apt-get update
not just use the default version your distro has on it's repo.

That's down to you not my installer.
the installer installs your apps dependencies (gambas components) gambas components your app needs.

 try this to add the gambas stable ppa and re-install the newer gambas version…

sudo add-apt-repository ppa:gambas-team/gambas3
sudo apt-get update
sudo apt-get purge gambas3*
sudo at-get install gambas3*

Topic solved after some years!

I successfully package my gambas apps as AppImage with the following guide: https://appimage-build…est/examples/gambas3.html

Note: the full path of the gambas project must to be without space.
The AppImage compiled for Ubuntu 20.04 works better than 22.04 on Ubuntu 18.04 and Ubuntu 22.04.

To package a Gambas app as AppImage, use the builder:

Here is two examples of recipe YML for build with AppImage builder:
