plentico / osxcross-target Goto Github PK

We updated this project for Ubuntu 20.04, but OSXCross still needs an older version of OpenSSL so you might need to add a step that looks like this:

-
  name: Downgrade libssl
  run: |
    echo 'deb http://security.ubuntu.com/ubuntu bionic-security main' | sudo tee -a /etc/apt/sources.list
    sudo apt update && apt-cache policy libssl1.0-dev
    sudo apt-get install libssl1.0-dev

Steps to create an OSXCross target:

1. Download OSXCross: https://github.com/tpoechtrager/osxcross/archive/master.zip
2. Unzip the downloaded archive from step 1 so the project lives at ~/Downloads/osxcross-master/
3. Login and download XCode from https://developer.apple.com/download/more/ (version 11.6 worked for me, the beta release for 12 did not)
4. Move the downloaded archive from step 3 so it lives at ~/Downloads/osxcross-master/Xcode_11.6.xip
5. Move into the OSXCross folder (cd ~/Downloads/osxcross-master) and run ./tools/gen_sdk_package_pbzx.sh Xcode_11.6.xip which creates the SDK that lives at ~/Downloads/osxcross-master/MacOSX10.15.sdk.tar.xz. Note: I would have loved to used a precompiled SDK from https://github.com/phracker/MacOSX-SDKs but using those gave me the following errors:

# crypto/x509
osxcross: error: cannot find libc++ headers
osxcross: error: while detecting target
# rogchap.com/v8go
In file included from v8go.cc:3:
../../../../go/pkg/mod/rogchap.com/[email protected]/deps/include/v8.h:23:10: fatal error: 'type_traits' file not found

6. Move the SDK created in step 5 into the "tarballs" directory: mv ~/Downloads/osxcross-master/MacOSX10.15.sdk.tar.xz ~/Downloads/osxcross-master/tarballs/MacOSX10.15.sdk.tar.xz
7. While still in ~/Downloads/osxcross-master/ run the build: ./build.sh. That should create a "target" directory with a bunch of files and folders in it, one of which is ~/Downloads/osxcross-master/target/bin/ that contains various cross-compilers, including o64-clang that we'll be using. The osxcross-target project is the "target" directory that's created using a hardcoded path that can be used with GitHub Actions.

After completing the steps above, you should be able to create a darwin binary using the following command (Update the paths to use your computer's username, not jimafisk):

env GOOS=darwin GOARCH=amd64 CGO_ENABLED=1 CC=/home/jimafisk/Downloads/osxcross-master/target/bin/o64-clang CXX=/home/jimafisk/Downloads/osxcross-master/target/bin/o64-clang++ go build -ldflags -s
