This sample Xcode project demonstrates how to build Go code for OS X / iPhone / iOS Simulator executables, as well as calling to and from Go.
This project installs its own local version of Go 1.5 and does not use or modify in any way any prior Go installation.
- Clone repo and
cdinto the directory - Run
./bootstrap.sh - Open the Xcode project
If you need to access the local Go environment from Terminal, cd into the directory then run source env.sh. This will define GOROOT, GOPATH, etc...
- Go code is built with absolute addressing which triggers a warning when linking the executable
(null): PIE disabled. Absolute addressing (perhaps -mdynamic-no-pic) not allowed in code signed PIE, but used in __cgoexp_45a75e65c81e_Test from build/iphoneos/main.a(go.o). To fix this warning, don't compile with -mdynamic-no-pic or link with -Wl,-no_pie
- Go code is not built with bitcode when building for iPhone
- Go code fails to build for iOS Simulator on i386 (the Xcode project is therefore configured to only use it in 64 bit mode)
