2. by Code::Blocks Add a compiler

open Code::Blocks, Click menu Settings>Compiler and debugger>Global compiler settings

stay Selected compiler Click below the drop-down box Copy, Fill in the pop-up window with : GNUstep MinGW Compiler

after , Click on Toolchain executables tab , take Compiler’s installation directory Choose as C:GNUstepmingwbin

3. establish Objective-C engineering

Create a Console Of C engineering , take main.c Delete , newly build main.m file , The contents are as follows :

#import <Foundation/Foundation.h>

int main (int argc, const char *argv[]) {

    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

    NSLog(@"Hello World!");

    [pool drain];

    return 0;

}

Right click main.m Click on property, choice Build tab , take Compile file And Link file All tick ,

choice Advanced, take Compiler variable Is changed to CC

4. Set compilation options

C:/GNUstep/GNUstep/System/Library/Libraries/libgnustep-base.dll.a

choice Search directories>Compiler, Click on Add, Add the following :

C:/GNUstep/GNUstep/System/Library/Headers

(2) Method 2

Right click the project to be created , choice Build options…,Selected compiler Compiler selection GNUstep MinGW Compiler, choice Compiler settings>Other options Fill in the -fconstant-string-class=NSConstantString -IC:/GNUstep/GNUstep/System/Library/Headers  -LC:/GNUstep/GNUstep/System/Library/Libraries

choice Linker settings tab , stay Other linker options Input in -lobjc -lgnustep-base that will do

5. increase .m File type highlighting and editor Association
