how to run a program written in go language?

[saccleo]

i want to run some program written in go language ( lego, an acme client for, let's encrypt) . i download an released program (https://github.com/xenolf/lego/releases/download/v1.1.0/lego_v1.1.0_linux_armv7.tar.gz) and run it.
i got an error" illegal instructions"
i thought recompile may solve the problem. so I installed go language by using entware source(opkg install go).
when i run go in a terminal i got the same error as mentioned above.
so what's wrong with the go program?

If your model supports Let's Encrypt, there's already an acme client in there (acme-client).

acme-client use http-01 challenge to issue a certification. unfortunately, my ISP block port 80, so i have to use other client.

i have resolved the problem by recompiling the program with option GOARM=5 in a docker under debian linux.
then it can run in my router.
