Question on Linux builds
Hi folks,

meanwhile I use Knossos on Ubuntu 20.04 which works fine.

However, I receive some strange errors when playing some of the mods: False colors (NVIDIA GT 1030 card with 440 driver) and freezes. It is not really reproducable.

Question now is, if compiling the engines by myself would

a) help, and
b) would affect the Knossos installations of the respective engines when doing a file integrity check

Reasons for asking are the compiler and the python 3.8.2 version. So far, the engine builds were from 14.04, weren't they?

System is a AMD Ryzen3 3200, 8GB RAM and 16 GB swap

Thanks in advance

Re: Question on Linux builds
The release builds are currently built on Ubuntu 16.04 but that shouldn't matter too much.

If you are experiencing graphics issues then it is highly unlikely that compiling the builds yourself would help but you can always try and see if it changes anything. There are no known issues with using self-compiled builds with Knossos.

 
Re: Question on Linux builds
Ok, maybe I found the problem: As I dont have a swap partition I first made a swapfile too small (2 GB with 8GB RAM). Then I increased it to 16GB, but still errors occured. Now I found that the /etc/fstab did not end with an empty line (after the swapfile entry). Did that, rebooted, and so far...

Will report back if that was nonsense, too

 
Re: Question on Linux builds
Ok, it wasn't that...

As self compiling with cmake doesn't work according to the instructions, could someone please give me the exact commnd lines for the 19.0.0, 3.8.3 and the other builds currently used in Knossos, please? According to the Readme doesnt work here (or I am too stupid...)

THX

Re: Question on Linux builds
Not sure what guide you are following but this one should be mostly accurate: https://github.com/scp-fs2open/fs2open.github.com/wiki/Building-on-Linux

 
Re: Question on Linux builds
Ok, here we go

cmake -S /home/$USER/Schreibtisch/fs2open.github.com/ -D FSO_FREESPACE_PATH=/home/$USER/

Re: Question on Linux builds
Ah, FreeType was missing from the install command. Try installing libfreetype-dev and then try again.

 
Re: Question on Linux builds
Ok, this time it worked. Does it matter that it is no AppImage for Knossos?

Thanks!

Re: Question on Linux builds
AppImage is just a special format for making it easier to distribute the builds. It is not needed if you build the binaries yourself.

Re: Question on Linux builds
As far as I know (which is not a lot), the AppImage basically wraps everything into a self-contained executable for a Linux application, not all that unlike what some Windows applications do. The downside is that it may (or rather, WILL) bloat the size of the program. Conversely, the end user can probably be confident that their program will run the way it's supposed to. Might be a really good way of distributing "fresh" releases of old software, which can only run with depreciated packages.

...There are other means of distributing a program as well. Flatpaks generally seem to be well-received, seemingly more so than Canonical's "Snap" format. All of these methods, mind you, are generally of a similar mind: to make Linux applications agnostic to the individual Linux distribution. That's really about all I know. That said, Flatpak strikes me as the best option, all things considered.
