fails to build ghc about nix-on-droid

[t184256]

Attempted to look into that, but hit an out-of-space error. Just wanted you to know that I'm on it, but it'll take some time.

[t184256]

Can reproduce under nix-on-droid.

By the way, how do you prevent long builds in nix-on-droid from being killed? =)

Building ghc times out even on Hydra (10h) and Hydra got some powerful hardware.

Can we use nix-on-droid on the android emulator? I tried and the app crashed (or maybe just exited with an error).

[t184256]

I foresee no problems with that approach as long as either: 1) the emulator emulates aarch64 or 2) you teach me how to run it in the emulator and I'll add support for the required architectures.

@t184256 I re-install the app, and building ghc succeeds.

BTW, on my phone (Meizu Pro 6s) building ghc took about 30 minutes, not as long as 10h. So I don't know your problem that long building is killed. But sometimes flyme os (customized Android by Meizu) can kill nix-on-droid when the screen is locked. So I permit nix-on-droid to run in the background and keep the screen unlocked while building ghc. This may help.

[t184256]

I re-install the app, and building ghc succeeds.

I reinstalled the app and ghc just installed without any compilation. O_o

Hydra shows nixos:release-19.03-aarch64 builds now.

Hooray?

Yeah I had no problem with GHC. Should close this.
