Crosscompiling from OSX:

export PATH=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin:$PATH export CC=pwd/sys/ios-sdk-gcc

set only for arm64, otherwise it is armv7

export CPU=arm64

select ios sdk version

export IOSVER=7.1 ./configure --prefix=/usr --with-ostype=darwin --with-compiler=ios-sdk --target=arm-unknown-darwin make -j4 make install DESTDIR=/tmp/r2ios

Natively compiling on iOS

SSH into your iDevice and run the following steps:

Setup SDK for ARMv6

Install 'APT 0.7 Strict' and OpenSSH packages from cydia.

apt-get coreutils install wget inetutils rsync git expat curl
Download missing packages from lolcathost:

wget http://lolcathost.org/b/libgcc_4.2-20080410-1-6_iphoneos-arm.deb wget http://lolcathost.org/b/libSystem.dylib
Install them

dpkg -i libgcc_4.2-20080410-1-6_iphoneos-arm.deb apt-get install com.bigboss.20toolchain cp libSystem.dylib /usr/lib cd /usr/lib ; ln -sf libSystem.dylib libm.dylib apt-get install make vim gawk git
/var/include/sys/stat.h is broken.

Solution: add 'int foo[3];' after 'st_rdev' at line 178
Get the varinclude tarball

wget lolcathost.org/b/varinclude.tar.gz tar xzvf varinclude.tar.gz -C /

Compilation

export CC=gcc
export CFLAGS=-I/var/include
export CPPFLAGS=-I/var/include
./configure --prefix=/usr --with-ostype=darwin
make
make symstall

Usage

export R2DIR=/private/var/radare2
export PATH=${R2DIR}/bin:$PATH
export DYLD_LIBRARY_PATH=${R2DIR}/lib
r2 ...

Building with the ARMv7 SDK

From coolstar repo we get the ios toolchain

apt-get coreutils install wget inetutils
apt-get install basename git make expat 
apt-get install org.coolstar.iostoolchain

Copy crt1.o and dylib1.o from your iOS SDK into /usr/lib

/Applications//Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/
Current r2 build requires 'gcc' as native compiler to build a standalone 'sdb' to precompile some files. This dependency will be probably

cd /usr/bin ln -fs clang gcc

Build

export CC=clang
export CFLAGS=-I/var/include
export CPPFLAGS=-I/var/include
./configure --prefix=/usr --with-ostype=darwin
make
make symstall

Packaging

Make a fake install in a temporary directory:

rm -rf /tmp/r2
make install DESTDIR=/tmp/r2
cd /tmp/r2
tar czvpf ../r2.tgz *

Clone the cydia repo from radare's github

git clone https://github.com/radare/cydia
cd cydia/radare2*
mkdir root
tar xzvf r2.tgz -C root
vim CONFIG # bump version
make

Signing

In order to enable debugger capabilities to the radare2 executable you will need to sign it using the following command:

cd binr/radare2
make sign
