alt Hacker News> do the build process on alpine linux and […] statically link musl libc
IIRC it used to be common to do builds on an old version of RHEL or CentOS and dynamically link an old version of glibc. Binaries would then work on newer systems because glibc is backwards compatible.
Does anyone still use that approach?
If you need glibc for any kind of reason, that approach is still used. But that won’t save you if no glibc is available. And since the folks here want to produce a musl build anyways for alpine, the easier approach is to just go for musl all the way.
