I am using Fedora Gnome … yesterday there were a lot of new updates to fedora and gnome.   Today I tried to use Gambas 3.20.99 ,  I can run an existing program, but if i atempt to edit anything, the instant the editor brings up a popup with syntax … the gambas program crashes … Quits .
I can edit a comment or a test string, but not a command or varaiable, that does not bring up a syntax popup.
I have reinstalled gambas with the instructions here "Gambas Upgrade Commands" That installed the same version 3.20.99
Same thing happens …. program Quits when trying to edit .
Is there a later version … did the above instructions not work properly ?
It could be a problem with fedora … Thumderbird mail would not work after the update and I had to install it from the Mozilla download rather than from fedora repos.
 

I have found it seems to be a problem with  the graphics module   it will work if I start the program with QT6 , but fail with QT4 or 5 or GTK

Gambas seem to be the only program that Gnome alowes to be started with different graphic modules .

 

did you get any error/warning messages when running the install commands?

mostly the ./configure command should show any problems with libraries/packages not being there.

The gambas install page you used (that's my page btw) reads the current fedora config from the gambas .gitlab-ci.yml file so all the commands should be current and okay.

the commands are working with latest fedora build:fedora-latest (#11349539049) · Jobs · Gambas / gambas · GitLab

do you get an error message if you try to run gambas from terminal?

$ gambas3

$ env GB_GUI=gb.qt5 gambas3

$ env GB_GUI=gb.gtk3 gambas3

Ps. you can start any gambas program that uses gb.gui with a choice of toolkit using the env method mentioned above.

eg.
$ env GB_GUI=gb.qt5 /path/to/program.gambas

The only way I can get Gambas to run properly in my current fedora Gnome is to run it with QT6 … will not work with any other.


Selected with    "  env GB_GUI=gb.qt6 gambas3"  or with the GUI in Gnome as shown above post.

 

Looks like gtk widget errors.

Have you tried changing the gtk theme?

plus latest gambas master is not 3.20.99 it's 3.21.99
perhaps the problem is now fixed?

do I have to delete the 3.20 and then install 3.21 ?

if you cloned the git repository you should be able to update it with git pull.
(your folder name suggests gambas-stable but a .99 version is dev master)

or re-clone latest

you could probably just install 3.21 over 3.20
or remove old first..

cd ~/gambas-stable
sudo make uninstall

I uninstalled the 3.20 and installed 3.21 …… still the same results will not run without QT6 .
 

i got no problems here with Fedora40
tested gtk3 qt5 and qt6 all okay

[System]
Gambas=3.21.99 9542528 (master)
Distribution=Fedora Linux 40 (MATE-Compiz)
Kernel=6.9.7-200.fc40.x86_64
Platform=x11
Desktop=MATE
WidgetTheme=bluementa

It must have to do with Gnome 

I tryed it with Gnome Classic and same results

I am tempted to install a second desktop …. but don't want to mess up a working system . 

i just installed gnome (both xorg and wayland) and no problems.

well I say no problems,, i had all sorts of issues (with the system) using kernel 6.14.5-100
if i use kernel 6.9.7-200 everything is okay.

[System]
Gambas=3.21.99 9542528 (master)
OperatingSystem=Linux
Distribution=Fedora Linux 40 (MATE-Compiz)
Kernel=6.9.7-200.fc40.x86_64
Architecture=x86_64
Cores=2
Memory=4318M
Language=en_GB.UTF-8
Platform=x11
Desktop=GNOME
DesktopResolution=96
DesktopScale=8
WidgetTheme=adwaita
Font=Cantarell,11

it seems to be the Kernel or nvidia driver .
I went back to 6.16.8.200 and the nvidia driver had to rebuild … but would not use my vidio card and would not display the correct resoulition …
but Gambas 3 did work … so maybe the next kernel will fix it,   but I am working now anyways  

at least I now have the latest Gambas 

I have given up on Fedora and Gnome for now …. installed LMDE … and tried to install Gambas .
NO JOY.   using this site :
Gambas Upgrade Commands

What have I done wrong ?

etting up libimlib2-dev (1.12.4-2) …
Setting up libwebkit2gtk-4.1-dev (2.48.5-1~deb13u1) …
Setting up qt6-webengine-dev:amd64 (6.8.2+dfsg-4) …
bash: ./reconf-all: No such file or directory
bash: ./configure: No such file or directory
make: *** No targets specified and no makefile found.  Stop.
make: *** No rule to make target 'install'.  Stop.

It would not wotk with stable

did work with development version

so finaly got 3.21.99 to install … BUT have no help files …Help browser has no information .

I do not know.
It looks like the commands were not run from within the gambas-stable cloned folder.

the initial git clone command should create the gambas-stable folder then the next command should cd into it.
