fails to build ghc #8

Closed chenyulue closed 4 years ago

chenyulue commented 5 years ago

I use nix-env -i ghc to install GHC. However, when compiling Distribution.SPDX.LIcenseId, I get the following error:

[123 of 270] Compiling Distribution.SPDX.LicenseId ( libraries/Cabal/Cabal/Distribution/SPDX/LicenseId.hs, bootstrapping/Distribution/SPDX/LicenseId.o ) utils/genprimopcode/ghc.mk:19: utils/genprimopcode/dist/package-data.mk: No such file or directory make[1]: [utils/ghc-cabal/ghc.mk:56: utils/ghc-cabal/dist/build/tmp/ghc-cabal] Killed make: [Makefile:123: all] Error 2 error (ignored): getting status of '/data/data/com.termux.nix/files/usr/tmp/nix-build-ghc-8.6.4.drv-1/ghc-8.6.4/utils/unlit/fs.c': Operation not permitted error: cannot unlink '/data/data/com.termux.nix/files/usr/tmp/nix-build-ghc-8.6.4.drv-1/ghc-8.6.4/utils/fs': Directory not empty

I have no idea why this happens and whether it is related to Nix-on-droid or just to GHC.

Could you take some time to look into it when you are free? Thanks!

My android version is 7.1.1

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 commented 5 years ago

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.

bbigras commented 5 years ago

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

t184256 commented 5 years ago

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 commented 5 years ago

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.
