[golang-dev] how to build golang with a lower version kernal requirement?

[f***@gmail.com]

I build golang program in ubuntu 18.04 and try to run it on centos 7 and
ubunbu 16.04.
it hint , "kernel too old."

ldd --version ldd (Ubuntu GLIBC 2.27-3ubuntu1) 2.27 #ubuntu 18.04 ldd
(Ubuntu GLIBC 2.23-3ubuntu1) 2.23 #ubuntu 16.04

glibc 2.24 above requires kernel 3.2 minimum glibc 2.23 requires kernel
2.6.32. minimum #ubuntu 16.04

Question:
1. how to build golang with a lower version kernel requirement?

2. on the other hand, if I build golang programe in ubuntu 16.04 , can it
be run on ubutu 18.04?

Build it on an older system with an older glibc.

2. on the other hand, if I build golang programe in ubuntu 16.04 , can it be run on ubutu 18.04?

Yes.
