IOS (iPhoneOS) Build Instructions and Notes

This guide will show you how to build twisterd for IOS on a linux machine.

Notes

Compilation, made on a linux
Application, tested on iPhone4 with IOS 7.1.2 (jailbroken)
All of the commands should be executed in a Terminal application.

Preparation

You need to install clang and llvm from distribution's repo. Then you need IOS toolchain and SDK. You can get them from iOS toolchain based on clang for linux.

You need to install openssl (view in cydia...) to your device and copy headers and libraries to your SDK as well.

REQUIRMENTS (leveldb, berkeley db and boost) WILL BE DOWNLOADED AND BUILDED BY runme-ios-onlinux.sh You need also to build leveldb, Berkeley DB for IOS.

And you need the boost sources.

Instructions:

Setting required variable

You should check variables set in runme-ios-onlinux.sh script.

export IPHONE_IP=""
export IOS_SDK=/usr/share/iPhoneOS6.0.sdk
export ARCH=armv7
export TARGET=arm-apple-darwin11
export LINKER_VER=236.3
export IPHONEOS_DEPLOYMENT_TARGET=6.0
export TARGET_OS=IOS
export CC="clang"
export CXX="clang++"
export PJC=2

Building dependencies and `twisterd`

Clone the github tree to get the source code and go into the directory.

 git clone https://github.com/miguelfreitas/twister-core.git
 cd twister-core/src

Building
```
 ./runme-ios-onlinux.sh
```
If things go south, before trying again, make sure you clean it up:
```
 make clean
```

If all went well, you should now have a twisterd executable in the twister-core directory. See the Running instructions below.

Running

If you have been set IPHONE_IP before running script, it's now available at /usr/bin/twisterd on your device. We have to first create the RPC configuration file, though.

Run /usr/bin/twisterd from SSH or on Mobile Terminal to get the filename where it should be put, or just try these commands:

mkdir -p "/User/.twister"
echo -e "rpcuser=user\nrpcpassword=pwd\nrpcallowip=127.0.0.1" > "/User/.twister/twister.conf"
chmod 600 "/User/.twister/twister.conf"

When next you run it, it will start downloading the blockchain, but it won't output anything while it's doing this. This process may take several hours. If you see a lonely connect: Operation timed out, don't freak out, it seems to work fine.

Other commands:

tail -f ~/.twister/debug.log
./twisterd --help  # for a list of command-line options.
./twisterd -daemon # to start it as a daemon.
./twisterd help    # When the daemon is running, to get a list of RPC commands

In order to get the HTML interface, you'll have to download it and link it in .twister:

 git clone https://github.com/miguelfreitas/twister-html.git /User/Library/Application\ Support/twister/html

Once you do that, it will be available at http://localhost:28332/home.html
