Go on iOS
|
|
=========
|
|
|
|
To build a cross compiling toolchain for iOS on OS X, first modify clangwrap.sh
|
|
in misc/ios to match your setup. And then run:
|
|
|
|
GOARM=7 CGO_ENABLED=1 GOARCH=arm CC_FOR_TARGET=`pwd`/../misc/ios/clangwrap.sh \
|
|
CXX_FOR_TARGET=`pwd`/../misc/ios/clangwrap.sh ./make.bash
|
|
|
|
To build a program, use the normal go build command:
|
|
|
|
CGO_ENABLED=1 GOARCH=arm go build import/path
|
|
|
|
To run a program on an iDevice, first make sure you have a valid developer
|
|
certificate and have setup your iDevice properly to run apps signed by your
|
|
developer certificate. Then install https://github.com/phonegap/ios-deploy.
|
|
At a first step, you can try building the famous hello world program to run
|
|
on your test device.
|
|
(The needed files are provided at https://github.com/minux/go-ios-examples.)
|
|
|
|
# assume your program binary is helloworld.go, build it into the
|
|
# example hello.app bundle.
|
|
CGO_ENABLED=1 GOARCH=arm go build -o hello.app/hello helloworld.go
|
|
# sign the executable using your developer certificate
|
|
codesign -f -s "iPhone Developer" --entitlements hello.app/Entitlements.plist hello.app/hello
|
|
# run the program inside lldb on iDevice, run `ios-deploy` for more
|
|
# command options
|
|
ios-deploy --debug --uninstall --bundle hello.app
|
|
# Depending on your ios-deploy version, you might need to enter "run"
|
|
# into lldb to run your program, and its output will be shown by lldb.
|
|
|
|
Notes:
|
|
- A dummy hello.app bundle is provided in this directory to help you get started.
|
|
- Running the program on an iDevice requires code sign and thus external linking,
|
|
if your program uses cgo, then it will automatically use external linking.
|
|
However, if your program does not use cgo, please make sure to add
|
|
import _ "runtime/cgo"
|
|
so that external linking will be used.

Known issues
|
|
============
|
|
- crypto/x509 won't build, I don't yet know how to get system root on iOS.
|
|
- Because I still want to be able to do native build, CGO_ENABLED=1 is not the
|
|
default, yet.
