1 Go on iOS
4 To run the standard library tests, run all.bash as usual, but with the compiler
5 set to the clang wrapper that invokes clang for iOS. For example, this command runs
6 all.bash on the iOS emulator:
8 GOOS=ios GOARCH=amd64 CGO_ENABLED=1 CC_FOR_TARGET=$(pwd)/../misc/ios/clangwrap.sh ./all.bash
10 If CC_FOR_TARGET is not set when the toolchain is built (make.bash or all.bash), CC
11 can be set on the command line. For example,
13 GOOS=ios GOARCH=amd64 CGO_ENABLED=1 CC=$(go env GOROOT)/misc/ios/clangwrap.sh go build
15 Setting CC is not necessary if the toolchain is built with CC_FOR_TARGET set.
17 To use the go tool to run individual programs and tests, put $GOROOT/bin into PATH to ensure
18 the go_ios_$GOARCH_exec wrapper is found. For example, to run the archive/tar tests:
20 export PATH=$GOROOT/bin:$PATH
21 GOOS=ios GOARCH=amd64 CGO_ENABLED=1 go test archive/tar
23 The go_ios_exec wrapper uses GOARCH to select the emulator (amd64) or the device (arm64).
24 However, further setup is required to run tests or programs directly on a device.
26 First make sure you have a valid developer certificate and have setup your device properly
27 to run apps signed by your developer certificate. Then install the libimobiledevice and
28 ideviceinstaller tools from https://www.libimobiledevice.org/. Use the HEAD versions from
29 source; the stable versions have bugs that prevents the Go exec wrapper to install and run
32 Second, the Go exec wrapper must be told the developer account signing identity, the team
33 id and a provisioned bundle id to use. They're specified with the environment variables
34 GOIOS_DEV_ID, GOIOS_TEAM_ID and GOIOS_APP_ID. The detect.go program in this directory will
35 attempt to auto-detect suitable values. Run it as
37 go run detect.go
39 which will output something similar to
41 export GOIOS_DEV_ID="iPhone Developer: email@example.com (XXXXXXXX)"
42 export GOIOS_APP_ID=YYYYYYYY.some.bundle.id
43 export GOIOS_TEAM_ID=ZZZZZZZZ
45 If you have multiple devices connected, specify the device UDID with the GOIOS_DEVICE_ID
46 variable. Use `idevice_id -l` to list all available UDIDs. Then, setting GOARCH to arm64
47 will select the device:
49 GOOS=ios GOARCH=arm64 CGO_ENABLED=1 CC_FOR_TARGET=$(pwd)/../misc/ios/clangwrap.sh ./all.bash
51 Note that the go_darwin_$GOARCH_exec wrapper uninstalls any existing app identified by
52 the bundle id before installing a new app. If the uninstalled app is the last app by
53 the developer identity, the device might also remove the permission to run apps from
54 that developer, and the exec wrapper will fail to install the new app. To avoid that,
55 install another app with the same developer identity but with a different bundle id.
56 That way, the permission to install apps is held on to while the primary app is
