1. 准備Ubuntu環境
Ubuntu 10.04
sudo apt-get install git-core libxar-dev bison flex patch openssl libbz2-dev libssl-dev autoconf
sudo apt-get install build-essential gnustep gobjc gnustep-make libgnustep-base-dev gnustep-devel uuid
gcc, g++等編譯器默認已經安裝
sudo apt-get install g++
Ubuntu 10.04 amd64:
在64位系統上，apt-get找不到xar，就從網站上下載xar安裝，要先安裝依賴文件libxar1, 再安裝xar
http://packages.ubuntu.com/hardy/xar
2.准備SDK和iPhone Fireware文件
2.1
iPhone1,2_3.1.2_7D11_Restore.ipsw
http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-7265.20091008.Xsd32/iPhone1,2_3.1.2_7D11_Restore.ipsw
2.2
iphone_sdk_3.1.2_with_xcode_3.1.4__leopard__9m2809.dmg
3. 准備iphonedevonlinux源代碼、SDK和firmware文件
3.1 checkout iphonedevonlinux源代碼
$ mkdir -p ~/iPhone/toolchain
$ cd ~/iPhone/toolchain
$ svn checkout http://iphonedevonlinux.googlecode.com/svn/trunk/ ./
目前checkout out的svn版本為revision 83
3.2 拷貝SDK，firmware文件到相應目錄
$ mkdir -p ~/iPhone/toolchain/files/firmware
$ mv iphone_sdk_3.1.2_with_xcode_3.1.4__leopard__9m2809.dmg ~/iPhone/toolchain/files/
$ mv iPhone1,2_3.1.2_7D11_Restore.ipsw ~/iPhone/toolchain/files/firmware/
4. 執行toolchain.sh
4.1 sudo ./toolchain.sh headers
4.2 sudo ./toolchain.sh firmware
由於GFW的原因，這一步可能不成功。如果失敗了，就手工修改toolchain.sh，直接添加解密firmware的key
修改toolchain.sh如下：
注視掉以下內容：
if [ -z "$DECRYPTION_KEY_SYSTEM" ] ; then
# echo "We need the decryption key for `basename $FW_RESTORE_SYSTEMDISK`."
# echo "I'm going to try to fetch it from $IPHONEWIKI_KEY_URL...."
#
# IPHONEWIKI_KEY_URL=$( wget --quiet -O - $IPHONEWIKI_KEY_URL | awk '
# BEGIN { IGNORECASE = 1; }
# /name="'${DEVICE}'/ { found_phone=1; }
# /.*'${TOOLCHAIN_VERSION}'.*/ && found_phone { found_firmware=1; }
# /.*href=.*/ && found_firmware { while(sub(/href=|"/,"", $3));; print $3; exit;}
# ')
#
# DECRYPTION_KEY_SYSTEM=`wget --quiet -O - "http://#www.theiphonewiki.com"$IPHONEWIKI_KEY_URL | awk '
# BEGIN { IGNORECASE = 1; }
# /.*VFDecrypt.*/ { print $3;}
# '`
DECRYPTION_KEY_SYSTEM="a8a886d56011d2d98b190d0a498f6fcac719467047639cd601fd53a4a1d93c24e1b2ddc6"
if [ ! "$DECRYPTION_KEY_SYSTEM" ] ; then
error "Sorry, no decryption key for system partition found!"
exit 1
fi
echo "I found it!"
fi
message_status "Mounting ${FW_RESTORE_SYSTEMDISK}..."
mount_dmg "${TMP_DIR}/${FW_RESTORE_SYSTEMDISK}" "${MNT_DIR}" "${DECRYPTION_KEY_SYSTEM}"
別忘了添加DECRYPTION_KEY_SYSTEM=...這一行
4.3 sudo ./toolchain.sh darwin_sources
