For the start, i use linux emulation for playing Dwarf Fortress game. It has very handy utilset that helps maintaining your fortress, DFHack & ui for it, DwarfTherapist. The problem is with running it, when trying to run, i got: ptrace attach - operation not permitted Both df and dfhack are running from the same user, tried to run dfhack as root and got ptrace attach: Invalid argument What should i do to diagnose the problem? and, if it is wrong arguments for ptrace, how do i allow user to use ptrace attach? -- with best regards, Krutov Mikle
