Everything went fine to compile minetest, but when trying to run it, i get:

minetest: symbol lookup error: minetest: undefined symbol: _ZN6JMutexC1Ev

a bit of strace minetest:

Any pointers would be nice, that might causing this issue

Tested again to build it. Still same issue from commit:

commit 993821a92448bf3573ac56dbfe67ee4b54172d06
Author: Perttu Ahola <celeron55@gmail.com>
Date: Fri Feb 3 14:50:49 2012 +0200

Is jthread installed, and has the game found it? All I could make sense of that is that it might have to do with jmutex, which is something from the jthread library.

Thank you, that was the problem. used jthread 1.3.0 and setup with cmake. reverted to 1.2.1 and use a normal configure, make, makeinstall and now minetest works.

Thank you for the pointer, appriciated alot. Possible now to make a package in Foresight Linux for all users :)
