Cross distro support

Describe the problem Some compiling tools set interpreter to nix store

Some users may compile with nix tooling and run on Linux LSB FHS

• On Devenv: Developer :grinning: -> Server FHS: Ops :sob:
• On Devenv: Developer :grinning: -> CI/CD On Devenv: DevOps :grinning: -> Server FHS: Ops :sob:

:sob: fail to run :grinning: Happy

To Reproduce

cc  hello.c -o hello
ldd hello
# /nix/store/lyl6nysc3i3aqhj6shizjgj0ibnf1pvg-glibc-2.34-210/lib/ld-linux-x86-64.so.2 => /nix/store/4nlgxhb09sdr51nc9hdm8az5b08vzkgx-glibc-2.35-163/lib64/ld-linux-x86-64.so.2 (0x00007f2a584be000)

Copy to machine without Nix store

./hello
exec: Failed to execute process './hello.a': The file exists and is executable. Check the interpreter or linker?

Then apply patchelf

cp hello hellow
patchelf  --set-interpreter  /lib64/ld-linux-x86-64.so.2 hellow

Copy to a machine without Nix store

./hellow
Hello, World!

Would this entail static compilation?

[hugosenari]

I'm a newbie on this topic. I don't know what would be the best solution. Options

• Apply patchelf
• Apply patchelf and pack to deb/rpm with fpm, translating deps names to platform pkgs
• Nix bundle
• Static compilation with musl
• Static compilation with cosmopolitan
• Systemd portable services
