I tried ArrayFire on a linux 64 bit computer with internet access from an internal 10.194.xxx.xxx local network.
I can compile without problem the provided examples/misc.
When I try to run blas the program waits for several minutes and then output
$ ./blas
src/gena/gi_core.cpp:37: src/license.cpp:323: cannot connect to license server (Cannot connect to license server system. (-15,570:115 "Operation now in progress"))
hit [enter]...
I suspect some ports are blocked by a firewall, so the question is which one?
