Hi Craig,
I have had to use gcc-4.8 with the `-march=native` compiler flag for compiling
and testing on ARMv7 (Raspberry Pi 2) . Is it possible for you to test with
that?
Also, it seems like some of the eventfd and signalfd related functionality is
missing in your environment or is in a non-standard path. Could you provide
some more details about your environment? In particular, it’d be great if you
can provide the following bits:
- DMTCP version;
- Linux kernel version;
- Libc version; and
- CPU architecture
Thanks,
Rohan
