firrtl VS patchelf

You need replace protoc with something like this: protobufRunProtoc in ProtobufConfig := (args => scala.sys.process.Process("protoc", args).!) in build.sbt and add protobuf3_6 to buildInputs. For example: https://github.com/TimothyKlim/firrtl/commit/be23dbfaeb043e01ea7d293243e5994715d00d2b

I mean, we don't have to hack the elf loader if we just rewrite every elf binary using patchelf: https://github.com/NixOS/patchelf

The parent commenter is already suggesting "just run a regex", so it seems like a trivial extension to their simple solution to "just run patchelf on every binary on your system"

Patching paths in text files typically used substituteInPlace (including in cowsay). For dynamic libraries, patchelf is typically used.

Install patchelf.

Thank you! I followed the instruction here, but it looks like I didn't actually install it, because my pacman -Q patchelf did not find anything. Maybe I was missing a dependency. Also, it was late so I didn't pay attention to warnings at the time.

How does an article on NixOS talk about the `rpath` issue without also mentioning the `patchelf` utility that NixOS developers created to solve this issue? It's a small tool that lets you modify ELF executables and binaries. It's also the recommended way for NixOS users to modify binaries to work properly.

So install it? https://github.com/NixOS/patchelf

NixOS doesn't have stable paths to shared libraries like macOS or other linux distributions (and this is the core feature) and always need to patch elf for current paths ( https://github.com/NixOS/patchelf ).
