How to compile HelloWorld in Intel x86-32 on Mac OSX/FreeBSD

How to compile HelloWorld in Intel x86-32 on Mac OSX/FreeBSD

Compile in your Terminal:

nasm -o hello.tmp -f macho hello.s && ld -arch i386 -macosx_version_min 10.6 -no_pie -e _main -o hello.o hello.tmp && ./hello.o

The Code:

section .data                   ; constants stored here

    msg db "Hello World!", 0xa  ; our string to be printed
    len equ $ - msg             ; get the length of our string

section .text                   ; labels stored here

global _main                    ; specify our main function - (ld -e main)

_syscall:                       ; label - system call - call kernel - how we print to the screen
    int 0x80
    ret

_main:                          ; label - technically int main()
    push    dword len           ; message length
    push    dword msg           ; message to write
    push    dword 1             ; file descriptor - 1 - stdout
    mov     eax, 0x4            ; system call number - 4 - system write
    call    _syscall            ; go to label(function call) - _syscall

    ;  add     esp,12          ;clean stack (3 arguments * 4)

    push    dword 0             ; exit code - return 0
    mov     eax, 0x1            ; system call number (sys_exit)
    call    _syscall            ; go to label(function call) - _syscall

How to put Applications on Jailbroken iPhone

How to put Applications on Jailbroken iPhone

Need:

• Jailbroken iPhone(with OpenSSH from Cydia)
• USB cable
• MacbookPro(for Xcode) 
• uikittools

Tested with:

• iPhone 5, running iOS 6.1(Jailbroken using Evasi0n Untethered Jailbreak iOS)
• USB Cable (used original cable)
• Xcode 4.6
• iPhone iOS 6.1 SDK

Step 1 - make sure Xcode is closed - stop automatic signing

---

First off you need to edit a configuration file within Xcode:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/SDKSettings.plist

Make a backup just in case you mess up:

sudo cp /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/SDKSettings.plist /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/SDKSettings.BACK

Edit the file like:

sudo nano /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/SDKSettings.plist

To save:

Control + X  then Y

Change

<key>CODE_SIGNING_REQUIRED</key>
<string>YES</string>
<key>CODE_SIGN_ENTITLEMENTS</key>
<string>YES</string>

to

<key>CODE_SIGNING_REQUIRED</key>
<string>NO</string>
<key>CODE_SIGN_ENTITLEMENTS</key>
<string>NO</string>

Step 2 - create the TCP connection between your Macbook and your iPhone

---

Go to

http://cgit.sukimashita.com/usbmuxd.git/

Download the latest, here:

http://cgit.sukimashita.com/usbmuxd.git/snapshot/usbmuxd-1.0.8.tar.bz2

Use a GUI tool or simply extract in Terminal:

tar -xjf usbmuxd-1.0.8.tar.bz2

cd to the "python-client" folder

Open Terminal and run to test the connection, Control + C to quit:

python tcprelay.py -t 22:2222

Now you can run these commands in the future:

ssh root@localhost -p 2222 - access the phone
scp -P 2222 root@localhost - send files to the phone

Step 3 - time to open Xcode

---

Click on your Project > Build Settings > Go to Code Signing > Code Signing Identity > Make sure it says "Don't sign code"

Make sure you set your target to "iOS Device"

Go to Product > Build for > Archiving

Step 4 - time to push your application to your jailbroken iPhone!

---

Example project name: NavBar

After building your application, its time to push it your phone, you need to find the path to your application in order to send it to your phone:

Open terminal again:

scp -r -P 2222 "/Users/noname/Library/Developer/Xcode/DerivedData/NavBar-gekkahxyyaepvgdkfkduwhlmqvqg/Build/Products/Release-iphoneos/NavBar.app" root@localhost:/Applications/

When prompted for the password, make sure your type "alpine"

User: root (already specified)
Password: alpine

After that is quickly transferred, Control + C to quit and then update your iPhone with:

ssh -p 2222 mobile@localhost uicache

User: mobile (already specified)
Password: alpine

To remove everything:

ssh -p 2222 root@localhost rm -rf /Applications/NavBar.app && ssh -p 2222 mobile@localhost uicache

By now you should see the application pop up on your home screen!
