Hi everyone,

Does anyone know if Gambas works with qt6?

I have a clean install of Debian 12 and I have install gambas3 from the apt

But when I run one of my apps I get a message saying qt5 could not be found

So when I did whereis qt5 I get a result

And I have tried with qt6 (full install) and im getting the same result qt5. Not found

So does Gambas not work with qt6 yet?

there is no gb.qt6 yet

you'll have to install qt5.

the gambas apt install "should" have installed the qt5 dependencies??
I have debian bookworm and had no problems.  qt5 was already installed :-\

did you mean Debian13 (Trixie)?  I've not tried 13

maybe if you install the dependencies for debian autotools install method it will work?
/install - Gambas Documentation

I assume you did apt update and apt upgrade before installing gambas?

Yea I did a clean install as well as apt update etc and a full gambas3 install but it keeps saying no qt5 found.


My development PC is using gambas 3.18.90 (Development version) could that be what's up?

Okay i have a few ideas.. (it's probably the last one)

is it just using the default gnome on wayland?

What happens if you type this in a terminal..

<HIGHLIGHT highlight="shell">
echo -e 'use "gb.gui"\nPrint Env["GB_GUI"]' | env GB_GUI=gb.qt5 gbs3
</HIGHLIGHT>

I use MATE desktop , if you just installed the default gnome then it probably hasn't even got Xorg / X11
gambas sucks on wayland , well to be more specific, wayland sucks for gambas, i'd recommend installing the xorg version of gnome.
Or a program called x-wayland

gambas should make a qt5-wayland component but maybe it needs the x11/xorg libs?

did you use the following to install ALL gambas components…

sudo apt install gambas3*

are your programs set to explicitly use gb.qt5 ?  if yes then on wayland you'll need to change it to gb.gui.qt or gb.gui then it will choose the qt5-wayland component or gtk depending on setting.

on my deb 12 wayland i do not see gb.qt5 component to choose so explicitly using gb.qt5 will not work.

using gb.gui.qt works okay though.

Oddly on my VM deb12 i did this…..

Set up the os, default gnome.  did update/upgrade , then apt install gambas3*

i could load gambas3 fine and the gambas "about" page showed it was using wayland gtk
i could load and run my programs that use gb.gui (all my programs use gb.gui)

I then used synaptic and installed MATE and MATE-extras  MATE-core etc.

Then when i rebooted it seemed wayland was gone.  Both MATE and my default gnome was now using X11 gtk and i no longer had all or any of the wayland issues.

 My system setup

I started with a minimum install of Debian 12
Install x11 and openbox
Installed gambas3

The about screen is saying I am using "X11" and "GTK3"

For some reason I could never get the keyboard to work in a gtk3 app that is using a workspace otherwise I would just switch to gtk3

so does it work if you make your app use gb.gui.qt instead of gb.qt5 ?

Right I have just spend all night re installed Debian 12

I have even used apt install qtbase5-dev and i am getting the following error message when I try to load a Gambas application

gb.gui.qt: Error 'gb.qt5' Component not found, unable to find any QT replacement components

I am not sure what to do so if anyone has any ideas I am all open

Like I said I would use the GTK graphics BUT for some reason when I am using a workspace in an application any form inside the workspace is not working with the keyboard when GTK is selected.

 post a copy of one of the failing applications and i'll see if i can get it to work here or not.

I don't understand why it's not working for you, like i say gambas and qt works okay on my fresh debian12

Did you try installing a desktop that uses X not wayland like MATE?
you don't have to use the MATE desktop but installing it should set up qt5 for you.

All I have installed is a mini version of Debian with no desktop

Then I use apt install xorg openbox to install the X11 and openbox window manager

Ahh then i'd guess you are missing some dependencies.
There's a list or requirements here…
/install - Gambas Documentation
gb.qt5    Qt5Core >= 5.3.0 Qt5Gui Qt5Widgets Qt5Svg Qt5PrintSupport
gb.qt5.ext    Qt5Core >= 5.3.0 Qt5Gui Qt5Widgets x11
gb.qt5.opengl    Qt5Core >= 5.3.0 Qt5Gui Qt5Widgets Qt5OpenGL gl x11

Note: Qt5OpenGL is not needed if your Qt version is >= 5.4.0
gb.qt5.wayland    Qt5Core >= 5.3.0 Qt5Gui Qt5Widgets
gb.qt5.webkit    Qt5Core >= 5.3.0 Qt5Gui Qt5Widgets Qt5Network Qt5Xml Qt5WebKit Qt5WebKitWidgets Qt5PrintSupport
gb.qt5.webview    Qt5Core >= 5.5.0 Qt5WebEngineWidgets
gb.qt5.x11    Qt5Core >= 5.3.0 Qt5Gui Qt5Widgets Qt5X11Extras x11-xcb

not sure what else to suggest.
(except do a proper desktop install like apt install mate-desktop-environment , it's likely normal desktop installs are installing a lot more than you are)

installing gambas via autotools might help.
the dependency install might install missing qt5 packages and the ./configure command should report and problems with missing things.

If you install an Ubuntu based distribution, e.g. Linux Mint you can then install the Gambas ppa, and Gambas, in Terminal with the command below. It will give you the latest Gambas stable version 3.18.4. I think you will find this will simply work.

sudo add-apt-repository -y ppa:gambas-team/gambas3 && sudo apt-get update && sudo apt-get -y install gambas3

I'm not so sure.
I think he is missing qt5 libraries.  the gambas ppa install will make gb.qt5 component only if it finds all it's qt5 requirements,
it will not install qt5 for you if it's not there.

Respects

 I did do a apt install qtbase5-dev but it's still saying no qt files

I'm about 10mins away from the office and when I bet there I shall try the echo command listed above

try this command i used the wiki dependency list to get these names and removed x11 and gl as they give many search results but this should help…

That should be all the libs required for gambas qt5 to install properly. (on mint, your debian results might differ)

x11 and gl also should be installed

I just installed Debian 12 Gnome yesterday and installed Gambas3 … I get exactly the same result as you did above.

my program runs just fine running wayland … only thing I noticed is the "ME.Center" does not work
If I switch to X then ME.center work

That command gives more results than you need.

You can omit various ones (like Chinese keyboards stuff and other non relevant results)

It is a good guide though.

Like I said using autotools compile and install method will give clear results.

Running these commands in the gb.qt5 folder…
./reconf
./configure -C -q

 will show exactly what's missing to get gb.qt5 working in gambas.

I did do a apt install qtbase5-dev

Yes but that's for compiling gambas is the -dev package. Do you have the actual package qtbase5 installed ?

Although see the list above to see what other packages you might need.

Later I might try a minimal deb install like you and get it all running.

Good luck. <EMOJI seq="1f60e" tseq="1f60e">😎</EMOJI>

Sorry for the delay I had to change the CMOS battery as it had died and reset the thing lol

Those commands do not install anything Andy it's a (rough) list of packages you need to get qt5 and gambas working.

sudo apt install libqt5gui5 libqt5core5a

And various others.
That's your job now to figure out exactly what's needed <EMOJI seq="1f601" tseq="1f601">😁</EMOJI>
(Or fix your program so it works on gtk <EMOJI seq="1f609" tseq="1f609">😉</EMOJI>)

Btw did you try apt install gambas3-gb-qt5 ?

I wondered if explicitly installing gb.qt5 may force install the needed packages. No guarantee that'll work though.

I have no idea why it does not work on gkt3 if the form with in a workspace needs keyboard input (I have a single form key capture program that tells me what key code was pressed and that works fine on GTK3)

I am about to try that

I keep getting message saying gb.qt5 not found


If you want to replicate what I have done so far This is how I did it

use a Network install of Debian 12 and when it asked to select a Desktop I have un-ticked both the Debian desktop environment and Xfce and Ticked SSH server and standard system Utilities

Once the system has installed and rebooted I run the following apt command

sudo apt –no-install-recommends install xserver-xorg xserver-xorg-video-fbdev xserver-xorg-video-intel xinit openbox mousepad -y

And then i installed Gambas with sudo apt install gambas3

Ok I have managed to get QT5 to install with the following commands

<LIST>

• <LI>apt install gambas3-qb-qt5
  apt install gambas3-qb-qt5-x11</LI>

</LIST>

But now when I run a program I get the following message on the screen

<IMG src="https://algpos.co.uk/gambas/IMG_5707.jpeg"> </IMG>

I am not sure what to do? should I wipe the machine and start again?

 So you don't have a desktop at all?
If not..
you'll need some kind of desktop (gui environment) to run a gui application

type

apt-cache search openbox

the will be a list of sessions.

lxde is minimal

sudo apt install openbox-lxde-session


If you do have a desktop , what type is it?

I have the standard OpenBox installed

I can run Gambas on the machine but i still get the error messages saying about the driver and then Gambas loads

openbox is just a windowmanager, it's not a desktop environment.

if you read the main openbox hompage http://openbox.org/wiki/Main_Page it says all about using openbox with your "desktop environment"

without a desktop environment installed I think you can't use gambas gui applications.
(certainly not properly without errors)

(EDIT: )

Sorry  i was wrong about this.  see post below where i found a solution.

install openbox-lxde-session or openbox-gnome-session to get a desktop environment then your gui applications includng gambas IDE should run properly.


Or you'll just have to work out what libraries/packages are missing from the error messages.

 I've got mine working okay.

How my deb install differed to yours….
i also install xorg and not just specific parts like xserver-xorg xserver-xorg-video-fbdev xserver-xorg-video-intel

apt install xorg

installed openbox config (and qt specific version) and some things to get a working openbox environment..

apt install obconf obconf-qt firefox-esr caja mate-terminal

caja for a file browser and mate-terminal as hitting the "terminal emulator" menu in openbox didn't work.

install complete gambas to ensure all qt stuff goes in….

apt install gambas3*

sudo reboot

on boot launch x

$ startx

gambas works and so does gb.qt5
