Objective-C under Ubuntu Linux
Compiling Everything from Scratch
The following scripts compiles and installs everything needed for Objective-C 2.0 from scratch. The script uses clang and libobjc2 for all the awesome new features like ARC, blocks, etc.
Reference manuals for GNUStep, including available APIs, etc, are available at http://www.gnustep.org/developers/documentation.html
NOTE: Unless you have a need for the above features, its recommended to install from the default repos as often the scripts below have issues.
sudo apt install gnustep
16.04, 16.10, & 17.04
In addition to building everything, this script also provides the ability to build the most recent version of four apps: Project Center, Gorm, GWorkspace, and System Preferences.

Open a new terminal or type source ~/.bashrc"
12.04
This uses the same as the 14.04 & 15.04 except there are some additional requirements.
On Ubuntu 12.04, the default installed version of CMake is 2.8.7 but you need 2.8.8 or later to compile LLVM. And the default installed version of GCC and G++ is 4.6 but you need 4.8 or later to compile LLVM.
For CMake, the solution is to download and compile CMake yourself. Use the existing CMake 2.8.7 and then replace it:
- Download the latest CMake version from the CMake web site (http://www.cmake.org/cmake/resources/software.html), and uncompress it in a folder.
- Create a _build directory in the CMake sources folder.
- From the _build directory, run the following commands to build and install CMake from sources:
cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr make cpack -G DEB sudo apt-get remove cmake cmake-data sudo dpkg -i cmake*.deb
To get GCC and G++ 4.8, do the following:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test sudo apt-get update sudo apt-get install gcc-4.8 g++-4.8 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 50
Now run the 14.04 & 15.04 script.
Test Code
The following is some Objective-C source code from the internet. It demonstrates blocks, Grand Central Dispatch, and the use of GNUStep GUI.
cat > blocktest.m << EOF #include <stdio.h> int main() { void (^hello)(void) = ^(void) { printf("Hello, block!\n"); }; hello(); return 0; } EOF cat > helloGCD_objc.m << EOF #include <dispatch/dispatch.h> #import <stdio.h> #import "Fraction.h" int main( int argc, const char *argv[] ) { dispatch_queue_t queue = dispatch_queue_create(NULL, NULL); Fraction *frac = [[Fraction alloc] init]; [frac setNumerator: 1]; [frac setDenominator: 3]; // print it dispatch_sync(queue, ^{ printf( "The fraction is: " ); [frac print]; printf( "\n" ); }); dispatch_release(queue); return 0; } EOF cat > Fraction.h << EOF #import <Foundation/NSObject.h> @interface Fraction: NSObject { int numerator; int denominator; } -(void) print; -(void) setNumerator: (int) n; -(void) setDenominator: (int) d; -(int) numerator; -(int) denominator; @end EOF cat > Fraction.m << EOF #import "Fraction.h" #import <stdio.h> @implementation Fraction -(void) print { printf( "%i/%i", numerator, denominator ); } -(void) setNumerator: (int) n { numerator = n; } -(void) setDenominator: (int) d { denominator = d; } -(int) denominator { return denominator; } -(int) numerator { return numerator; } @end EOF cat > guitest.m << EOF #import <AppKit/AppKit.h> int main() { NSApplication *app; // Without these 2 lines, seg fault may occur app = [NSApplication sharedApplication]; NSAlert * alert = [[NSAlert alloc] init]; [alert setMessageText:@"Hello alert"]; [alert addButtonWithTitle:@"All done"]; int result = [alert runModal]; if (result == NSAlertFirstButtonReturn) { NSLog(@"First button pressed"); } } EOF # ====================================================================== # COMPILE USING THE FOLLOWING COMMAND LINES, OR CREATE A MAKEFILE # ====================================================================== # Using COMMAND LINE clang `gnustep-config --objc-flags` `gnustep-config --objc-libs` -fobjc-runtime=gnustep -fblocks -fobjc-arc -lobjc blocktest.m clang `gnustep-config --objc-flags` `gnustep-config --objc-libs` -fobjc-runtime=gnustep -fblocks -lobjc -ldispatch -lgnustep-base Fraction.m helloGCD_objc.m clang `gnustep-config --objc-flags` `gnustep-config --objc-libs` -fobjc-runtime=gnustep -fblocks -lobjc -fobjc-arc -ldispatch -lgnustep-base -lgnustep-gui guitest.m # Using MAKEFILE cat > GNUmakefile << EOF include \$(GNUSTEP_MAKEFILES)/common.make APP_NAME = GUITest GUITest_OBJC_FILES = guitest.m include \$(GNUSTEP_MAKEFILES)/application.make EOF make openapp ./GUITest.app
General Note: When compiling your own code, it is generally good to tell clang both the family and version of the runtime: -fobjc-runtime=gnustep-1.8.1 (The current version number can be had by looking at the latest ANNOUNCE filename in https://github.com/gnustep/libobjc2 (e.g., ANNOUNCE.1.8.1))
