Hah platyna, i remember you from long ago:biggrin: To the issue at hand - it could well be some incompatile library version.


I suggest to install gdb, the gnu debugger (yum install gdb) and start rolauncher with it, it might be able to give some insight in where exactly it is crashing.


Once gdb is installed, naviage to the regnum directory and launch a console, then issue gdb ./rolauncher
This will bring you inside the gdb console ready to debug. now just type run or r to get rolauncher executed with the debugger attached.
Once it crashed it will pause and you can issue more commands, i suggest to issue bt to get a backtrace on the function calls - paste the output here, it might give a hint which library is the culprit.


Exit gdb with the command quit
Good luck and a happy new year.

Not really useful info in there.

Regarding rolauncher, i remember it could crash related to issues with themes, can you try to disable any special effects and themes? Also can you run ldd on rolauncher and paste its output here?
Also try to run the game executable directly, just to see if it crashes or just produces some error.

[_Lutz_]

$ ldd -v /usr/local/regnum/rolauncher
not a dynamic executable

I have 2 pc, here.. with fedora, 29 and 30, regnum don't start.
the fedora 29, is not a fresh installation, I upgraded system since fedora 26 and worked till 28
the pc with fedora 30, it's fresh install on nvme (i had ssd with fedora 28), the theme is dark breeze (kde), i tryed on gnome with adwaita (default), no success also

to play i need to plug old ssd card with fedora 28.. sad

I see, can you try strace -o strace.log -Tfe trace=openat,open ./rolauncher, put it to i.e. pastebin and put a link here or in a pm? Maybe we can find out what its trying to load just before it crashes.

[_Lutz_]

I did this command in both OS

strace on fedora 30
https://pastebin.com/yuCE1fyd

strace on fedora 28
https://pastebin.com/zD9rGx1U

on fedora 28 I closed after load login window

maybe some issue with fonts?

Very nice you did both, it looks definitely like some issue with themes, not some missing library.

See if there are more settings regarding that.

I.e. on cinnamon i can set default fonts + sizes, theme for window borders, mouse pointer, controls, desktop elements separately (all set to adwaita). And try disable all effects, all that visual candy.


Edit: I just read that with new gnome they added a new adwaita theme, so it could well be there are problems with it. Try to get some older theme, maybe you can download the old adwaita and use it on fedora 30 for a test.

I found the problem... [font configs on fedora 29/30]

I did a hard work with fonts on this system, and I configured to get best font rendering ever, but I copy my entire home to new installation.

1st I test renaming the files ~/.fonts ~/.fonts.conf and ~/.config/fontconfig/fonts.conf I think the file ~/.fonts.conf is decrapted, not sure about that

but the real problem was in ~/.config/fontconfig/fonts.conf, after relogin, system created new one with few things and all worked. If I use old file.. regnum not load, I didnt check which exactly block config making game crash. My fonts rendering didnt changed

I instaled others gtk-2 and gtk-3 themes also, but wasnt the problem, now all work with gnome default

on kde/gnome i dont use antialising/hint configs by display manager (using system default).

Any1 with Fedora 29/30, check font configs

Thank you very much for help Enio and give me some light about that.

Very welcome! Glad to hear you figured it out and good to know the fonts can be an issue :thumb:

some help pls

[platyna]

10 yeas have passed and the problem still persist.

I also learned I have "infractions" on forums, no idea how, and they do not seem to be related to the posts they link to, tried to PM admins about it, but they have PMs off.

I ran strace and removed this file: /usr/share/fonts/bitstream-vera-sans-fonts/VeraBd.ttf RO client proceeded to the EULA and then crashed again when I agreed to it. So I removed whole /usr/share/fonts/liberation-sans/ and managed to start the game...and all my chars are level 1 mages with empty inventories in the starting area. What the heck?! I had four chars - all high level and fully geared, with a lot of stuff from xim bought boxes...

What's up guys? I remember I put quite some money in this game, where are my skills and items???


Cheers!
