Gambas 3 won't compile in Mint 20 [SOLVED]

[Jerry N]

I have gambas programs that I wrote and compiled in Mint 19.3 (and earlier). In Mint 20, when I load these programs in gambas I get the error messages about missing gb.qt4.ext and CComponent.Load.626. After these error messages, the program loads into the Gambas IDE but will not compile. Anyone have a clue about how to solve this? I have not found a way to install these missing pieces.

Ubuntu/Mint 20 have pretty much dumped QT4, so you'll either need to convert your old programs or keep a VM of Mint 19 around. These were the only QT packages I could find for Gambas 3:

Code: Select all

gambas3-gb-qt5-ext              - Gambas extended Qt GUI component          
gambas3-gb-qt5-opengl           - Gambas OpenGL component with QT5 toolkit  
gambas3-gb-qt5-webkit           - Gambas WebKit component

Ubuntu/Mint 20 have pretty much dumped QT4, so you'll either need to convert your old programs or keep a VM of Mint 19 around.

Gambas still requires some qt4 libraries and they should be installed with it.

Code: Select all

    gb.qt4.la
    gb.qt4.so
    gb.qt4.so.0
    gb.qt4.so.0.0.0
    gb.qt4.component
    gb.qt4.gambas
    gb.qt4.info
    gb.qt4.list

What may have happened is that there's been a packaging error by Ubuntu. I think that the only thing the op can do is go to the gambas page on sourceforge and try to get the problem sorted by people who are more familiar with it.

Looking at Sourceforge, it appears that gambas hasn't been updated in 3 years. Does that mean gambas is on its way to being a dead language? I really don't want to write programs in python when gambas is event driven and design of forms/control panels is so easy and obvious. OK - I am old and lazy!

<opinion mode on>
It was already that way from the outset. It's not a standard language used by the open source community, it's just one dude's pet project, and it seriously lacks cross-platform support, though some diehard hax0rs have got it running in Windows, and I've known community projects that took good ideas written in Gambas and rewrote them in C/C++. Still: https://forum.gambas.one/ you might get some help there.

I was able to solve the problem by starting a new project with a project type of "Graphical Application". I copied my previous code into "FMain.class but I had to completely recreate the Fmain.form. This was a simple form (6 buttons, a text area, and a couple of labels) so that was easy. The program now compiles and runs in Mint Mate 20. Now I don't have to convert the program to Python, if I even can. I am old and impatient and find creating forms in Python (tkinter) to be extremely tedious.

Thanks for the help and comments
