I'm wondering why it appears that setresgid is not declared on your system. So I am asking which libc you are using, and what version it is. For example, on my system setresgid is declared in <unistd.h>; I am running glibc 2.33. But that is likely a side issue. To build a Go distribution for Solaris, use the bootstrap.bash script that I mentioned.
