Go package for building go-tun2socks libraries for macOS, iOS, and Android. Builds go-tun2socks binaries for Linux and Windows.
- macOS host (iOS, macOS)
- Xcode (iOS, macOS)
- Go >= 1.12
- A C compiler (e.g.: clang, gcc)
- gomobile (iOS, macOS, Android)
- xgo (Windows, Linux)
- Docker (Windows, Linux)
- Other common utilities (e.g.: git)
Apple Golang Runtime
We use a custom Golang runtime to build the iOS and macOS framework built off Go 1.12. The patch improves memory reporting to the OS. This should not be necessary after Go 1.13 is released (scheduled for August 2019).
Additionally, Go 1.12 calls private APIs on Darwin, which is not approved for Mac App Store distribution. We have applied this patch, scheduled for release on Go 1.12.2.
You can use our pre-compiled Darwin binary, at
tools/go or build it yourself:
# We assume that Go is installed in /usr/local; this may vary on your system. cd /usr/local/ # Temporarily move the current Go version, so as not to clobber $PATH. mv go go1.12 # Download the Go source. git clone https://go.googlesource.com/go cd go git checkout release-branch.go1.12 # Apply the patches. git fetch https://go.googlesource.com/go refs/changes/17/159117/5 && git cherry-pick FETCH_HEAD git fetch https://go.googlesource.com/go refs/changes/40/170640/6 && git cherry-pick FETCH_HEAD # Update the version. echo "go1.12-dev-runtime" > VERSION # Build the runtime. cd src GOROOT_BOOTSTRAP=/usr/local/go1.12/ ./make.bash # Verify that the installed binary matches the custom version (i.e. 'go version go1.12-dev-runtime darwin/amd64'). go version
After building the framework, you can delete the custom runtime and revert to Go 1.12.
As of Go 1.12, gomobile does not support building frameworks for macOS. We have patched gomobile to enable building a framework for macOS by replacing the default iOS simulator build.
Until we upstream the change, the (Darwin) binary to enable this behavior is located at
# Find out the path of the installed gomobile (i.e. ~/go/bin/gomobile). which gomobile # Temporarily rename the installed gomobile. mv ~/go/bin/gomobile ~/go/bin/gomobile-prod # Copy the patched gomobile binary. ln -s `pwd`/tools/gomobile ~/go/bin/gomobile # Initialize gomobile. gomobile init # Build the macOS framework. ./build_macos # Revert the changes. rm ~/go/bin/gomobile mv ~/go/bin/gomobile-prod ~/go/bin/gomobile
Linux & Windows
We build binaries for Linux and Windows from source without any custom integrations.
xgo and Docker are required to support cross-compilation.
