  And then you discover your program can't resolve hostnames because "DNS responses shouldn't be that big".

    Can you explain how musl is related to this DNS resolving problem?

    But honestly, they really shouldn't.

AppImage is sufficient.

  nope, it still requires at least the glibc version that the appimage was compiled against. snaps, flatpaks nor appimage solve the long-standing glibc versioning issue that plagues portable Linux binaries. the closest I've seen to fixing this issue is https://github.com/wheybags/glibc_version_header https://github.com/wheybags/glibc_version_header

Plenty of tools to setup sysroots for that, e.g. https://wiki.gentoo.org/wiki/Crossdev https://wiki.gentoo.org/wiki/Crossdev

Trick question: glibc doesn't support that. Trying to statically link with glibc is a fool's errand.
- account42 4y ago
  glibc doesn't support static linking, but you can fully static link with another libc if that is what you wanted to do. Not that it is needed for forward-compatible Linux binaries since newer glibc versions are backwards compatible so dynamically linking the oldest one you want to support works fine. Would be nice if glibc/gcc supported targetting older versions directly without having to have an older copy installed but that is a convenience issue.

When trying to statically link everything, glibc is not as much a problem as GPU drivers are if you want binaries that work on more than one system
