How to change all nix packages' RUNPATH to RPATH?

[amosbird]

I have customized toolchains that rely on LD_LIBRARY_PATH while I still want to use binaries from nix-env like cmake and ninja.

LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID: CentOS

nix-env (Nix) 1.11.2

That should be achieved by dropping our patch for it: https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/tools/misc/binutils/default.nix#L21

Note that you'll have to build basically everything from scratch by yourself, if you take the simple direct approach.

@vcunat I was trying to do that but failed. It keeps giving me warnings about package conflicts. Could you give me some help build everything from scratch? Could we have an option in nix-env which lets user choose if they want rpath or not?

I don't think adding the option would help the conflicts (whatever those are exactly).

@vcunat I've cloned the nixpkgs repo and dropped the newdtags patch. After installing a brand new nix-env toolset, removing all the nix store and profiles, I did nix-env -f /path/to/my/nixpkgs -i binutils. It was compiling for a long time and finally gave me a confliction. What should I do?

@vcunat this dtags patch seems to have no effects on whether RPATH or RUNPATH being used. I've tried dropping the patch or setting link_info.new_dtags = FALSE;. All the nixpkgs still have RUNPATH being set instead of RPATH.
