[v2] Cross Compilation Investigation
Although there is the options for using xgo, this article suggests it might be possible to cross-compile in a more lightweight way using zig: https://dev.to/kristoff/zig-makes-go-cross-compilation-just-work-29ho
Hey thanks for posting this!
Hey, Great job creating this. Ran into a small issue. Wails CLI v2.0.0-beta.33
App Type: desktop Platforms: darwin/universal Compiler: C:\Program Files\Go\bin\go.exe Build Mode: Production Skip Frontend: false Compress: false Package: true Clean Build Dir: false LDFlags: "" Tags: []
Building target: darwin/universal
Crosscompiling to Mac not currently supported.
Crosscompiling is not working for linux as well. got any solutions?
You'll notice that this is still a WIP.
Oh my bad. I was following a video from youtube where the author himself is explaining the crosscompiling process and it was working fine for him. Sorry.
This ticket is for the V2 version which I do not believe has working cross-compile at this time.
V1 used to work with what was available.. if it isn't working now I would open an issue on that.
Didn't mean to be harsh.
Cross compilation for v2 works for all scenarios apart from when the target is Mac and the compilation host isn't. If you really want to cross compile right now you can do so using GitHub actions. Both the October app and https://riftshare.app take this approach. I'll update the docs with this information over the weekend 👍

V1 is at bug+feature freeze.
Oh okay. But I could not get cross-compiling to Linux working as well. Anyway, Thank you for this awesome project. I'll start looking for alternatives to this compiling issue. wails build -platform linux Wails CLI v2.0.0-beta.33

Latest versions should work for you but you need docker
This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.
We may leave "Cross-compilation" for Mac as a github actions task for v2. I will timebox trying to get xgo working to 1 evening and then leave this as a post-v2 task. The majority of people developing for Mac will have a Mac so I'm not sure how many people this really affects.
Cross compilation will be handled by GitHub actions for v2. Bumping this down the road.

How to cross compile linux/arm
Using GitHub actions is the best way
Cross compiling to darwin target works on linux host with osxcross.
Requirements:
- Package the Xcode SDK from an macOS host. Please ensure you have read and understood the Xcode license terms before continuing.
- Build the toolchain with
./build.sh
- Build the runtime library with
./build_compiler_rt.sh
Examples:
CGO_CFLAGS="-mmacosx-version-min=10.15" CGO_LDFLAGS="-fuse-ld=lld -mmacosx-version-min=10.15 -framework UniformTypeIdentifiers" CGO_ENABLED=1 GOOS=darwin GOARCH=amd64 CC="o64-clang" CXX="o64-clang++" go build -tags desktop,production -buildmode=pie -buildvcs=false -ldflags "-s -w" -a -o build/bin/Phantom-darwin-amd64
CGO_CFLAGS="-mmacosx-version-min=11.1" CGO_LDFLAGS="-fuse-ld=lld -mmacosx-version-min=11.1 -framework UniformTypeIdentifiers" CGO_ENABLED=1 GOOS=darwin GOARCH=arm64 CC="o64-clang" CXX="o64-clang++" go build -tags desktop,production -buildmode=pie -buildvcs=false -ldflags "-s -w" -a -o build/bin/Phantom-darwin-arm64
Then you can make an universal binary with:
lipo -create -output build/bin/Phantom-darwin build/bin/Phantom-darwin-amd64 build/bin/Phantom-darwin-arm64
The resulting binary can be packaged into .app
. Running codesign and notary on an macOS host will work with the cross compiled binary:
rachel@rachels-iMac-Pro phantom % ./codesign.sh
Conducting pre-submission checks for Phantom.app.zip and initiating connection to the Apple notary service...
Submission ID received
id: (redacted)
Upload progress: 100.00% (11.9 MB of 11.9 MB)

Current status: Accepted..........

The staple and validate action worked!
You can try using https://github.com/indygreg/apple-platform-rs for codesigning on Linux, however I haven't tested it yet.

WARNING Crosscompiling to Linux not currently supported.
Hi, until this investigation is concluded; I wanted to solve all of the cross compilation and targeting issues for my own project so I cooked up a Docker solution inspired by go-releaser-cross. It is available as open source here so feel free to use it.
Thank you!
