It seems solaris prefers "sys/loadavg.h" over "stdlib.h" when fetching the load average. For Illumos based OSes it was required to include "sys/time.h" to ensure that "hrtime_t" was defined. https://www.illumos.org/issues/6002 It also required setting the ldflags "-fno-stack-protector -lssp" to avoid undefined symbols when linking with gcc. /opt/local/go/pkg/tool/solaris_amd64/link: running gcc failed: exit status 1 Undefined first referenced symbol in file __stack_chk_fail /tmp/go-link-138622936/000002.o __stack_chk_guard /tmp/go-link-138622936/000002.o
