Is there a good way to make binary files compiled on a high-version machine run on a low-version machine?

I have a project that uses CGO. After compiling on an ubuntu 20.04 compilation machine, it is distributed to other machines for execution, but many of these machines have very low ubuntu versions, which may be ubuntu 16.04 or ubuntu 18.04.

In this way, when executing the binary file, an error similar to version `GLIBC_2.29' not found will be reported.

I try to use -a -ldflags '-extldflags "-static"' when go build. But it seems that because of the use of cgo, it cannot be compiled successfully.

Is there any good way, such as adding appropriate tags when go build, to solve this problem?

I use a docker container with a centos7 image and build my shared libs there; https://github.com/ITRS-Group/cordial/blob/4f119f7893c67b817baaad23ed75b1ba134bf9c2/Dockerfile#L35

(pls don't judge my Dockerfile skills, it's a learning experience ;) )

Did you try:

export CGO_ENABLED=0
go build

?

Thanks. It is indeed a good solution to use containers

Because cgo is used, setting CGO_ENABLED=0 will cause problems, and may not compile successfully
