Building lime.ndll on Apple Silicon Mac #1640

Closed tobil4sk closed 2 months ago

tobil4sk commented 1 year ago

Created this to keep track of the status of native Apple Silicon builds of the lime.ndll.

Todo:

After applying these patches, it is possible to build the ndll and build/run projects as expected.

player-03 commented 1 year ago

For any changes involving submodules, please start with the 8.2.0 branch and submit changes to that branch.

The branch includes a build guide that may help debug, but still feel free to ask if not.

tobil4sk commented 1 year ago

Created a new branch based on 8.2.0 as suggested. The linker error was due to a problem with the libpixman patch, which I have explained in more detail here: https://github.com/openfl/libpixman/pull/1.

I've created a new PR with the 8.2.0 based branch, which allows for a successful build of the lime.ndll on arm64 Mac with haxelib run lime rebuild mac -DHXCPP_ARM64: #1642. This also requires the most recent development version of hxcpp. I've pasted the installation instructions in case anyone is interested:

Expand for detailed installation instructions ```sh # install updated hxcpp with arm64 building support haxelib git hxcpp https://github.com/HaxeFoundation/hxcpp.git # clone forked version of lime from PR #1642 git clone https://github.com/soccertutor/lime.git --branch fix/m1-build-ndll --recursive # set lime library path haxelib dev lime ./lime # rebuild lime haxelib run lime rebuild mac -DHXCPP_ARM64 ```

Since the ndll is still loaded from the Mac64 path for now, we had to move the new arm64 binary:

cd $(haxelib libpath lime)
rm ndll/Mac64/lime.ndll
cp ndll/MacArm64/lime-64.ndll ndll/Mac64/lime.ndll

We also ran into this issue: #1750. ~~We managed to work around it by creating symlinks in /usr/local/bin and /usr/local/lib, see: https://brettterpstra.com/2022/09/28/homebrew-and-slash-usr-slash-local-slash-bin-on-m1-macs/~~.

UPDATE: It looks like /usr/local/lib may no longer be a default path for dyld anymore, see #1750.

Despite having to use these awkward workarounds, openfl test mac -DHXCPP_ARM64 now successfully runs our project. UPDATE: Seems to only build successfully with the -clean flag.

how whould i build the macos arm64 dll on a x86_64 and i have xcode

ido-pluto commented 1 year ago

For some reason after installing the lime fork and doing all the steps, I got a segmentation fault

openfl test html5 -DHXCPP_ARM64
Could not link to neko.
Called from lime/_internal/backend/native/NativeCFFI.hx line 613
Called from lime/system/CFFI.hx line 171

Uncaught exception - Segmentation fault

If I put the MacArm64/lime-64.ndll into ndll/Mac/lime.ndll Is seems to work, but only for:

openfl test mac -DHXCPP_ARM64
tobil4sk commented 1 year ago

openfl test html5 -DHXCPP_ARM64

@ido-pluto The html5 target doesn't use hxcpp or lime.ndll so there is no need to build here with the -DHXCPP_ARM64 flag. However, it does seem odd that this causes a segmentation fault, there could be something wrong with the conditional compilation in my PR.

player-03 commented 1 year ago

Lime does use the ndll when building, which could explain the error.

If so, there's a second solution: the -eval flag skips lime.ndll when building. The flag was only recently merged into 8.2.0-Dev, so you'd need to pull that first.

👋 Ran into this as well - any closer to this being resolved?

ido-pluto commented 9 months ago

Use the x86 version of haxe without brew (from the website). This works without any issue

bguiz commented 9 months ago

Ah will give this a go - thanks!

Use the x86 version of haxe without brew (from the website).

I learned a while back that there are now two different versions of Homebrew. One for Intel and one for Apple Silicon, and you can actually install both on the same computer.

I needed the Intel version on my M1 Mac to locally build HashLink binaries a while back, and I mentioned what I did to install Intel Hombrew on the Haxe forums. Maybe it'll help you out.

Now that the PRs have been merged, it is possible to build lime.ndll on apple silicon and build and run projects, with the following requirements:

Then run:

lime rebuild swf
lime rebuild mac

So I think it's time to close this issue!

Also, in the develop branch you can now pass the -arm64 flag to do this:

lime rebuild mac -arm64

Same requirements as above (particularly for hxcpp).

Love to see this completed
