GNU Make 4.3 from 20.09 is broken on some devices

[t184256]

GNU Make 4.3 from 20.09 cannot spawn any processes, aborting with Function not implemented. https://discourse.nixos.org/t/9875 A workaround that builds gnumake-4.3 that works and doesn't trigger a rebuild of everything is enabled with system.workaround.make-posix-spawn.enable, but it's ugly. The issue currently known to manifest on only one device now. Please, contribute by reporting your Android/kernel versions and whether or not unworkarounded make 4.3 is functional on your device, especially if it's not.

• Android 9, Linux 3.10.102, aarch64, vanilla make 4.3 is broken, workaround fixes the issue.
• Android 8, Linux 4.4.83, aarch64, vanilla make 4.3 is working fine.

@Gerschtli, let's move the make discussion here out of #90.

Yes, I have limited access to a device that seems to have gnumake-4.3 spawn processes fine. The regression came with the rebase to Make 4.3 (NixOS/nixpkgs#0cfe9f3ae25f5c4627664476bececb31e8b0143e), which was the first release to default to using posix_spawn, IIRC.

Alright, I will add myself to the list of broken devices:

• android: 10
• system: "aarch64-linux"
• host os: Linux 4.4.205-perf+
• multi-user?: no
• sandbox: no
• version: nix-env (Nix) 2.3.7
• channels(nix-on-droid): "home-manager-20.09, nix-on-droid-20.09, nixpkgs-20.09.1683.1ae46bffe4a, nur-gerschtli, unstable-21.03pre250878.a52e974cff8"
• nixpkgs: /data/data/com.termux.nix/files/home/.nix-defexpr/channels/nixpkgs

It also happen to my phone.

• android: 10
• system: "aarch64-linux"
• host os: Linux 4.9.186-perf+
• multi-user?: no
• sandbox: no
• version: nix-env (Nix) 2.3.7

I'm hitting the same error,

device: Samsung Galaxy Tab S7+
android: 11
kernel: Linux 4.19.113-21033171
system: "aarch64-linux"
multi-user?: no
version: nix-env (Nix) 2.4pre20201201_5a6ddb3
channels(nix-on-droid): "nix-on-droid-20.09, nixpkgs-20.09.3376.1ac507ba981"
nixpkgs: /data/data/com.termux.nix/files/home/.nix-defexpr/channels/nixpkgs

I'm getting the error when trying to build a flaked config in a nix-shell -p nixFlakes

Same problem. I'm getting the error when usin make, cargo, or cabal.

device: Asus ZenFone Max Pro M2
android: 9 (API 28)
system: aarch64-linux
kernel: Linux 4.4.153-perf+
multi-user?: no
version: niv-env (Nix) 2.3.10
channels: "home-manager release-20.09, nix-on-droid release-20.09, nixpkgs nixos-20.09"
nixpkgs: /data/data/com.termux.nix/files/home/.nix-defexpr/channels/nixpkgs

Notes to self: right before the crash proot catches a SIGSYS, caused by seccomp. Can be observed with elevated proot's verbosity. tracee/seccomp.c already has handle_seccomp_event_common to retrigger modified calls. Next steps seem to be, learning what setresgid does, who called it, why is it blocked, how to sidestep it and why is this device-specific.

[t184256]

I can't believe it. Call for testing!

Either

• disable the make workaround option, back up your /data/data/com.termux.nix/files/usr/bin/proot-static, and switch to the does-this-fix-make branch using nix-channel or
• start anew bootstrapping from https://nix-on-droid.unboiled.info/bootstrap-does-this-fix-make.

Then test compiling pretty much anything using make, the bare minimum should be running a nix-shell -p gnumake --run make after creating Makefile containing

all:
    echo test

[noonien]

The test ran successfully on my device.

Awesome, thanks for the report!
