Impossible installation on Linux

This version is for Linux with Ubuntu 22.04 as the base. Ignore the 20.04 in the filename, I forgot to rename it.
Cinnamon 22.2 is based on Ubuntu 24.04 and requires a separate DEB package.
But you can easily build it from the source code.

1. Install dependencies. Most will already be installed.
   sudo apt install libgtk-3-dev
   sudo apt install mesa-common-dev
   sudo apt install libpulse-dev
   sudo apt install libudev-dev
   sudo apt install libxcb-xinput-dev && apt install libxcb-xfixes0
   sudo apt install libusb-1.0-0-dev
   sudo apt install libmp3lame-dev

2. build denise
   git clone https://piciji@bitbucket.org/piciji/denise.git denise
   cd denise
   cmake -B builds/release
   cmake --build builds/release -j 8
   cmake --build builds/release --target install

Thank you for that. Building went smooth, but it still doesn't work. Denise starts fine, but after closing and reopening only the background process is active and the main window does no longer display. There's probably something wrong with my system, I have some other problems with it as well. I switched back to v2.6 for the time being. Thanks again for your quick reply and help.

I just tried it in a live session of Mint CNM 22 and there I could open and close Denise without any problem. So the fault is probably on my system. However, even in the live session the install didn't fully complete because there was an error saying "Installed-Size is not available KiB". Don't know if this is any help.

I was able to use Denise 2.7 in Mint Cinnamon 22.2 without any problems. An incorrect setting might be causing the issue. You could try renaming the Denise settings files "C64_settings, Amiga_settings, global_settings" in the .config folder. This will revert to the default settings. If it then works without problems, please send me the problematic config files.

"Installed-Size is not available KiB"
This is just display information. I'll see if I can change it.

I tried 2.7 again and now it seems to work. The installer still freezes (I have to xkill the process to end it) but everything gets installed and works. It sometimes happens that starting Denise does not display the main window even though the "denise" process is running in the background. Once this happens I can only get the main window back after restarting the computer. It's hard to pinpoint when this happens. But that's just a minor problem, I just leave Denise running.

Thanks again for a great emulator.

PS: I upgraded to Mint 22.3 Cinnamon now.

The installer installs following Dependencies:
libgtk-3-0,libpulse0,libudev1,libxcb-xinput0,libxcb-xfixes0,libmp3lame0
One of them might be causing a problem in your system.
