In first place, THANK YOU, for a detailed explanation about zero-k on Linux issues.
About 1) I didn't understand what's the point about my post, cause I'm far away how internally Spring / Lobby works
About 3) I was desesperate, cause don't know other way to launch Zero-K lobby, however, a Spring "lobby" (or not) launcher appears just after installing all packs that I mentioned in my OpenSUSE. I was thinking it was the simpliest lobby for Linux (the window is called "Spring 96" on launching it).
About 5) I located the "infolog.txt" file in ~/.config/spring. As you guessed, apparentely, spring compiled for OpenSUSE doesn't search on "mods" folder:
Using read-write data directory: /home/falelovsky/.config/spring/
Using read-only data directory: /home/falelovsky/.spring/
Using read-only data directory: /usr/share/games/spring/
Scanning: /usr/share/games/spring/maps
Scanning: /usr/share/games/spring/base
About 6) That's most a maintainer headache, but there are many application for OpenSUSE that are updated near each week and however, they are avaiable in repos in less than two weeks. I wish I could do that job. I'll investigate about it.
I tried to launch springweblobby's QT port, but I'm behind a proxy now, so I'll try in my other PC. However, I don't understand why it launch a Java plugin ... in chrome and firefox.
I'll report more news later.
Thank you very much for all your information
I think I'm near to play Zero-K in my OpenSUSE!!!!!!! At last!!! ;)
