I have tried that and built the VM again, but I keep getting the same
mprotect error message :( Any other ideas?
From: oscogvm/build.linux64ARMv8/HowToBuild:
vvv======vvv
If running the resultant squeak vm gives an error something like
mprotect(x,y,PROT_READ|PROT_EXEC)
or
memory_alias_map: shm_open: Permission denied
you need to enable shared memory for the COG JIT.
As root:
chmod 777 /dev/shm
echo 'none /dev/shm tmpfs rw,nosuid,nodev 0 0' >> /etc/fstab
mount /dev/shm
The squeak vm should now work.
