how do I remove `GLIBC_2.27' requirement at compile time?

Question

I've been using a docker image for c++ compilation. It's based on Ubuntu 18.04. When I attempt to run on some Ubuntu 16 systems, I get this message:

/lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.27' not found

I'll post the full ldd output below. I like using the newer compiler. I would prefer to not compile with an older Linux base image (but I will if necessary). I statically link most libraries, but I haven't been statically linking glibc. A number of web sources recommend against that. Is there some way I can tell my newer compiler (gcc 7.3) to not require the newer glibc? ldd -v output:

Answer 1

I faced the same problem.

/lib/i386-linux-gnu/libm.so.6: version `GLIBC_2.27' not found (required by your_lib.so) 

After searching over the internet, I found some links that could be useful.

Static link: Link with -static. See How can I link to a specific glibc version?

Using docker: See Can docker solve a problem of mismatched C shared libraries?

Proprietary solution: See https://github.com/wheybags/glibc_version_header

I have decided to follow the first one. So I created a static library for your_lib.so and linked it statically with my binary.
