Since recently (the last few days?) I've bee getting this error when starting GNU APL:
shm_open(/apl-svars) failed: No such file or directory
shm_open(/apl-svars) failed: Undefined error: 0
*** Failed to start APnnn: processor -1 will not accept incoming shared variable offers. Expect surprises.
When looking at the code it looks like it's intentional.
Regards,
Elias
