git-annex isn't available on M1 Macs #5701

adswa · 2021-05-28T15:32:11Z

I don't have a machine to verify or test this, but a group of M1 Mac users just reported that they can't install git-annex. The workaround that they found is recorded here. To cite the relevant parts:

So the problem is that git-annex is not available for M1 macs, natively.

Solution:

1- Install Rosetta 2: Open a terminal and execute

/usr/sbin/softwareupdate --install-rosetta --agree-to-license

2- Download the git-annex DMG file from here: https://downloads.kitenet.net/git-annex/OSX/current/10.10_Yosemite/git-annex.dmg

3- Open the DMG file. Drag and drop the git-annex app to the /Applications folder.

4- In the terminal, run:

/Applications/git-annex.app/Contents/MacOS/git-annex

Once you do that, a message will appear saying that you can't execute that.

5- Open the System Preferences. Go to Security & Privacy. In the general tab, click on "Open anyway". Another message will apear, click open.

6- In the terminal, run:

/Applications/git-annex.app/Contents/MacOS/git-annex

You should see the output of git-annex.

7- Create a symbolic link so it's always on the path.

cd /usr/local/bin
sudo ln -s /Applications/git-annex.app/Contents/MacOS/git-annex

The text was updated successfully, but these errors were encountered:

FWIW, filed datalad/git-annex#61 to eventually/hopefully provide a native build (if that is what is needed)

adswa · 2021-05-28T17:42:14Z

thanks!

adswa · 2021-07-21T08:10:20Z

I vaguely recall @yarikoptic reporting that this was fixed... Did I dream this, or is there indeed git-annex for M1 macs now?

mih · 2021-07-21T08:48:09Z

Maybe: https://git-annex.branchable.com/forum/Apple_M1_Silicon/

adswa · 2021-10-08T06:57:38Z

I think its ok to close this issue. It does not so much belong into datalad, and while not optimal, there are some ways to get git-annex for M1 users. Its apparently possible to use it via Rosetta2, and homebrew (which has become available for M1 macs) has bottled all git-annex dependencies. Maybe it even bottles git-annex itself soon.

JoshuaDietz · 2021-11-03T23:00:04Z

6- In the terminal, run:

/Applications/git-annex.app/Contents/MacOS/git-annex

When I do this step I just get
dyld[1525]: Library not loaded: @executable_path/B Referenced from: /Applications/git-annex.app/Contents/MacOS/bundle/git-annex Reason: tried: '/Applications/git-annex.app/Contents/MacOS/bundle/B' (code signature invalid (errno=1) sliceOffset=0x00000000, codeBlobOffset=0x000FC4A0, codeBlobSize=0x00006700 for '/Applications/git-annex.app/Contents/MacOS/bundle/usr/lib/libiconv.2.dylib'), '/usr/local/lib/B' (no such file), '/usr/lib/B' (no such file) zsh: abort /Applications/git-annex.app/Contents/MacOS/git-annex

any idea on how to fix this?

adswa · 2021-11-04T07:46:28Z

I personally have no idea, and also no hardware to try this myself. Sadly, brew also hasn't bottled it up: https://formulae.brew.sh/formula/git-annex#default. I'll reopen the issue in hopes of someone with M1/mac experience to come by.

adswa · 2022-01-14T14:25:01Z

Saving a collection of links from the chat on updates with brew (sadly, no steps forward):

judging from Homebrew/brew#7857, the brew team has troubles to bottle the haskell compiler (but that list may be outdated, because it looks like there is a formula: https://formulae.brew.sh/formula/ghc). As far as I know, Rosetta2 is the official way to get support for x86-64 applications when there is no Apple Silicon alternative.
I think the latest attempt to bottle was Homebrew/homebrew-core#88995, but stalled. I guess someone with haskell knowledge is needed, or, as @mslw said, someone with homebrew / compiling knowlege. Looking back at it, in addition to the attempt to change the build instructions you mention, the build for the latest version bump Homebrew/homebrew-core#92348 still fails on M1 with what looks like 🤷‍♂️some mismatch in the build environment 🤷‍♂️ (logs are under "Files changed")

yarikoptic · 2022-01-14T20:53:00Z

to contribute I guess we would need some M1 box. I guess I could buy one (and provide ssh access), or here are some virtual providers:

https://www.scaleway.com/en/hello-m1/ - €0.1/hour
https://www.macstadium.com/ - 12c/hour? But then have some "MacStadium for open source.
We are proud to support the free and open source community by offering free Mac minis to eligible projects.". So I have applied for DataLad, and pointed to this issue

update1: macstadium gave us an instance for an open source project. Waiting for details on setup

Hi there -- I've tried a few times to get git-annex built on M1 macOS: Homebrew/homebrew-core#88995, Homebrew/homebrew-core#93863

Homebrew CI always attempts to build a binary package on version bumps, so you'll see several other attempts here: https://github.com/Homebrew/homebrew-core/pulls?q=is%3Apr+is%3Aclosed+in%3Atitle+git-annex

The build invariably fails with an error like

ghc: could not execute: opt

I don't really understand why, since opt (provided by LLVM) should be in PATH during the build. Attempting to add it again to PATH during the build does not work either.

I also saw a suggestion in the GHCUp repo to export the environment variable OPT for a similar problem, but that didn't seem to work.

I have one last idea, and if that fails, I'll try to crank up the verbosity of the build. I know Homebrew well, but know next to little about Haskell, so I'll need a little help here if I'm still unsuccessful.

Many other Haskell builds on M1 require an LLVM installation (they fail when it's not available), but none of the others fail in this way, so I'm not really sure what the problem is here. I recall a user having reported being able to successfully build git-annex from source using Homebrew on M1 macOS, though.

carlocab · 2022-01-29T15:20:38Z

So I tried setting --with-llc and --with-opt, but that didn't work (cabal didn't recognise the options), I also set --extra-prog-path to the location where llc and opt can be found, along with LLC and OPT in the environment. That didn't work too. See Homebrew/homebrew-core#94060.

I then upped the verbosity of the logs. It didn't get much more informative than

ghc: could not execute: llc
/opt/homebrew/opt/ghc/bin/ghc returned ExitFailure 1

which isn't helpful. Still, here's the log in case I missed something: arm.log.tar.gz (N.B. ~14M uncompressed)

@angerman, if you don't mind taking a look at this, I'd appreciate it.

yarikoptic · 2022-01-29T15:51:29Z

Thank you @carlocab for taking a stab at it!

adswa · 2022-01-31T07:19:50Z

Also from my side thanks a lot for looking in to it, @carlocab!

adswa · 2022-02-09T09:45:05Z

@yarikoptic could you add information on the new virtual M1 mac somewhere (sorry if I missed this)?

yarikoptic · 2022-02-09T11:49:55Z

Where? Do you want access @adswa ?

adswa · 2022-02-09T12:14:23Z

yes please. @mslw probably too?

mslw · 2022-02-09T12:53:56Z

Yes, I'd be interested - not immediately, but I'd happily give it a try in the near future.

yarikoptic · 2022-02-09T13:51:03Z

@adswa you should have access now, please add @mslw ssh key into the mix

yarikoptic · 2022-02-09T14:09:50Z

linking issue in datalad/git-annex: datalad/git-annex#61 (comment) : @jwodder:

@yarikoptic It looks like Haskell Stack (which is used to build git-annex) doesn't properly support M1 Macs yet.

adswa · 2022-02-09T14:48:04Z

I had a few minutes and tried to build git-annex on that M1, here's what I did so far:
Anything stack (setup, build) segfaulted immediately, under all shells.

Then I went for cabal instead of stack.
I got until cabal install -j --only-dependencies in the git-annex source repository.
This fails like this:

I checked the LLVM version.
brew (if I understand it correctly) said that LLVM is preinstalled on macOS

datalad@26696 git-annex % brew info llvm                                               
llvm: stable 13.0.0 (bottled), HEAD [keg-only]
Next-gen compiler infrastructure
https://llvm.org/
Not installed
From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/llvm.rb
License: Apache-2.0 with LLVM-exception
==> Dependencies
Build: cmake ✘, swig ✘
Required: python@3.10 ✘
==> Options
--HEAD
	Install HEAD version
==> Caveats
To use the bundled libc++ please add the following LDFLAGS:
  LDFLAGS="-L/opt/homebrew/opt/llvm/lib -Wl,-rpath,/opt/homebrew/opt/llvm/lib"

llvm is keg-only, which means it was not symlinked into /opt/homebrew,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

==> Analytics
install: 37,461 (30 days), 104,782 (90 days), 332,272 (365 days)
install-on-request: 22,691 (30 days), 61,686 (90 days), 224,768 (365 days)
build-error: 2,621 (30 days)

I'm not sure what "is not symlinked" means in practice.

It seems the system has it installed (if llvm-gcc is the correct thing here, I'm really not sure):

datalad@26696 git-annex % llvm-gcc --version                                           
Apple clang version 13.0.0 (clang-1300.0.29.30)
Target: arm64-apple-darwin21.2.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin
datalad@26696 git-annex % which llvm-gcc
/usr/bin/llvm-gcc

but adding any of those paths into $PATH does not resolve the problem.

GHC does not work with LLVM 13. You need to brew install llvm@12 and then add /opt/homebrew/opt/llvm@12/bin to your PATH. (Not symlinked roughly means it is not added to your PATH to avoid conflicts with Apple-installed software. Emphasis on "roughly" -- it means slightly more than that.)

thanks much!

I just wanted to provide one more data point. Today I managed to install git-annex painlessly with homebrew, running

brew install --build-from-source git-annex

it took about 25 minutes, but then git-annex test passes without problems.

carlocab · 2022-07-17T06:09:57Z

Yes, we've had reports at Homebrew about users being able to build git-annex successfully from source. Unfortunately, it does not work in our CI for some reason.

carlocab · 2022-09-30T06:58:04Z

Just an FYI: the git-annex build for M1 macOS was fixed recently at Homebrew, so you can now do brew install git-annex. You may need to brew update if you've disabled auto-update and haven't done brew update in a while.

It seems the issue was a process leak in GHC 8.10. We were able to build git-annex successfully using GHC 9.2 (+ some patches).

This is great news, thanks for the update @carlocab !

I think we can close this issue now.
