[SOLVED] segmentation fault with Lords of Xulima (uses mono)

hagabaka · 2015-12-22 04:05:18

Hello, I got Lords of Xulima from GOG and it's crashing with a segfault on start up. I've posted on their support forum too, but I wonder if other Arch users have seen similar problems or found solutions.

If I run the game with the GOG launcher, I get a stack trace:

Lords of Xulima> ./start.sh

Native stacktrace:

I also tried bypassing the GOG launcher like this, although I'm not sure it's right. I get two errors before the same stack trace:

gmisc-unix.c:70: assertion 'filename != NULL' failed

Got a SIGSEGV while executing native code. This usually indicates

The c files with assertion "filename != NULL" are from mono source, and they are checking whether some file path is absolute. But since they're getting a NULL I guess there's no way to find out what file the game is trying to open.

The above is with the mono bundled with the game. If I use the Arch packaged mono, it gets a little farther, showing a window titled "Lords of Xulima" briefly, but then it shows an error reporting dialog about the sound library "Un4seen". I'm guessing this is because I don't have the library installed system wide, but there's no package for it in repo or AUR, I have no idea how to build it. I feel like it would be less effort to try to get the bundled mono to run...

OK, I found the solution:
Since I'm on 64-bit, I need to replace game/libbass.so with its 64-bit version, which is included in the "x64" directory from http://www.un4seen.com/download.php?bass24-linux
After that the game runs with Arch packaged mono:

cd game
mono LoX.exe

Arch Linux
