Compile IOS program from linux commandline - ios

Question

I want to compile my IOS appication from linux terminal(command line)....
Is it possible to do so, if yes, then how?

Answer 1

Yes, it's possible.
At least you need:
Assembler and Linker: cctools and ld64 from apple opensource.
Compiler: Clang/LLVM
SDK, include headers and libraries.
Utilities: such as ldid codesign tool.
Step 1 : The compiler
Clang/llvm >= 3.2 is highly recommended and tested.
If you want to build clang/llvm from scratch, Please refer to this link to build a svn version for your linux distribution.
If your distribution already provides clang/llvm packages，make sure it is 3.2 release or above. Lower version may work but isn't tested.
for Ubuntu 13.04 and later, clang/llvm already provided in repos, please run:
$sudo apt-get install gcc g++ clang libclang-dev uuid-dev libssl-dev libpng12-dev libicu-dev bison flex libsqlite3-dev
to install some dev packages, other dev packages related to llvm/llvm-dev should be installed automatically.
Step 2 : The assembler and linker
The latest cctools-855 and ld64-236.3 had been ported from Apple opensource to linux. the porting process is a little bit complicated, also with a lot of codes modified for linux, let's just skip it.
please check out the codes from:
svn checkout http://ios-toolchain-based-on-clang-for-linux.googlecode.com/svn/trunk/cctools-porting
Build it:
$ sed -i 's/proz -k=20 --no-curses/wget/g' cctools-ld64.sh
$ ./cctools-ld64.sh
$ cd cctools-855-ld64-236.3
$
$ ./configure --target=arm-apple-darwin11 --prefix=/usr
$ make
$ make install
For Ubuntu 13.04, since the clang/llvm 3.2 package use a customized libraries/headers path. please setup CFLAGS and CXXFLAGS first before run configure.
$export CFLAGS="-I/usr/include/llvm-c-3.2"
$export CXXFLAGS="-I/usr/include/llvm-c-3.2"
Step 3: The iPhoneOS SDK.
The old iPhone SDK with ARC support extracted from xcode had been provided in Download Sections. You can directly download it and extract it to /usr/share
For iOS 4.2: https://ios-toolchain-based-on-clang-for-linux.googlecode.com/files/iPhoneOS4.2.sdk.tar.xz
For iOS 5.0: https://ios-toolchain-based-on-clang-for-linux.googlecode.com/files/iPhoneOS5.0.sdk.tar.xz
For iOS 6.0: https://ios-toolchain-based-on-clang-for-linux.googlecode.com/files/iPhoneOS6.0.sdk.tar.xz
For other iOS versions, You may need follow these steps to get the SDK for your self.
Step 4: The utilities
iphonesdk-utils is a utility collection for iOS development, provides below utilities:
NOTE: (Some of them are collected from internet with some modifications.)
ldid : codesign tool, with armv7/armv7s support and other changes from orig version. it will be involked by ld64 after link complete.
ios-clang-wrapper : automatically find SDK and construct proper compilation args.
ios-switchsdk : switch sdk when multiple version of SDK exist.
ios-pngcrush: png crush/de-crush tool, like Apple's pngcrush.
ios-createProject : project templates
ios-genLocalization : iOS app localization tool based on clang lexer.
ios-plutil : plist compiler/decompiler.
ios-xcbuild : convert xcode project to makefile, build xcode project directly under linux.
Download the source tarball from: https://ios-toolchain-based-on-clang-for-linux.googlecode.com/files/iphonesdk-utils-2.0.tar.gz
Build and install it:
$./configure --prefix=/usr
$make
$make install
Build App
Now you can build and install your project simply doing:
$cd ProjectDir
$make
$make install IPHONE_IP=<your own device IP

Answer 2

The above solution given by Barjomet is correct incase if its not mavericks, but if it is Maverics then following is the solution:
1) Install the appropriate command line tool
2) for building :a)xcodebuild -list -project .xcodeproj
b)- xcodebuild -scheme build
