The getrandom syscall only appeared in Linux kernel 3.17, so in your kernel it is not present, which causes the error. The fact that SYS_getrandom is defined likely means that your installed Linux headers are from a different, newer kernel. Please, check that your linux-libc-dev package version on the build system matches the kernel you're running. If it doesn't then I'd say it's a configuration problem.

Also, you can define BOOST_UUID_RANDOM_PROVIDER_FORCE_POSIX to disable getrandom backend and use /dev/urandom.

@Lastique thank you, I fixed it according to your suggestion.

So before we close this, I'd like to know if you used the BOOST_UUID_RANDOM_PROVIDER_FORCE_POSIX workaround. If we need to add a fix here I'd like to know.
