Not all platforms have a "libc". Linux is an example: there is no standard c library and while glibc is very common, there are several distributions that use other C libraries like uClibc and musl. For example a gaming handheld i have which is running Linux uses uClibc
Another example is Windows, the platform API does not provide a C library (even MSVC has its own). While there is an MSVCRT.DLL it is not recommended to link against it as it is there only because some other software relies on it and its semantics are for around Visual C++ 4 (IIRC).
It is already next to impossible to write software that requires “Linux” and nothing more with all the kernel functionality that can be enabled or disabled.
Linux is a component of many different platforms, which indeed do provide different libcs, but also different t.l.s. libraries, different c.p.u. architectures, different Linux configurations and whatever else.
As far as I know with respect to Windows, it only provides stable interfaces viāC libraries, and does not have a stable binary interface to the kernel directly.
For containers Go static binaries are great. Used to build Docker containers for Kubernetes using a 8 MB Go binary. That was all you needed. No libraries. No "minimum OS' Alpine or Ubuntu image.
Error doesn't work for everyone else. It's a hack, you wouldn't do it if it wasn't for backwards compatability.
