The daily build library path should output:
V-Play library path: /home/eigel/libs/V-PlaySDK/Desktop/Qt/4.8.1/gcc/../../../V-PlaySDK/daily/lib/lib64
on 64 bit systems. I guess you already checked if you’ve installed the latest daily build 1.3.7 (you can check that in the V-Play SDK maintenance tool), or better, have you also tried the latest 1.4.0 stable build, which indeed should have the 64 bit check (v-play.prf line #140)?
Regarding the crash, this sounds like there are still some wrong dynamic libraries linked, if the problem won’t be fixed with the 1.4.0 installation you could try to run in debug mode and check if you get a useful breakpoint (resulting from SIGSEV or similar).
If all of this won’t fix your problem, we’ll go and get a 64bit Linux VM up an running this evening. 😉
