Windows下Object-C编译环境的搭建:
1. 下载并安装以下两个软件 :
GNUstep System(我用的版本是:gnustep-msys-system-0.25.1-setup.exe)
GNUstep Core(我用的版本是:gnustep-core-0.25.0-setup.exe)
下载地址: http://www.gnustep.org/experience/Windows.html
安装方法:直接点击上exe文件即可,另外,最好选择默认安装路径:C:/GNUstep。
2. 测试:
安装完成后,进入"开始-程序-GNUstep-Shell",出现的窗口就是shell 窗口,就可以进行编辑(vi/vim)和编译(gcc) object-C代码了。
这个shell的默认路径是 /home/<username>,例如,我的是 /home/samsung/。
另外,我直接用devc++,UE等编辑软件编辑程序,放在/home/samsung/下,进行编译和运行。
下面是我的代码和运行结果:
hello.m的源码:
- #import <stdio.h>
- int main(int argc,const char *argv[]){
- printf("hello world/n");
- return 0;
- }
编译运行:
- samsung@coco ~
- $ gcc hello.m
-
- samsung@coco ~
- $ ls
- a.exe hello.m
-
- samsung@coco ~
- $ ./a.exe
- hello world
-
- samsung@coco ~
3. 一个更复杂的例子:
代码: 包含3个文件。
1) Fraction.h:
- #import <Foundation/NSObject.h>
-
- @interface Fraction: NSObject {
- int numerator;
- int denominator;
- }
-
- -(void) print;
- -(void) setNumerator: (int) d;
- -(void) setDenominator: (int) d;
- -(int) numerator;
- -(int) denominator;
- -(void) setNumerator: (int) n ddd: (int)d;
- -(void) setNumerator: (int)n : (int)d :(int) a;
-
- @end
4. 总结:
1. 用户也可以使用cygwin+ GNUstep来进行开发;
2. object-C是以m为后缀的,用GNU GCC来编译;
3. 整个环境和linux差不多;
4. 初看起来,也很easy了,起码,环境搭建时,我没有遇到任何阻碍,呵呵,加油!!!
2)Fraction.m
- #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;
- }
-
- -(void) setNumerator: (int) n ddd: (int)d {
- numerator = n;
- denominator = d;
- }
- -(void) setNumerator: (int)n : (int)d :(int) a {
- numerator = n;
- denominator = d;
- printf("+++++a = %d +++ /n", a);
- }
- @end
3) main.m
- #import <stdio.h>
- #import <Foundation/Foundation.h>
- #import "Fraction.h"
-
- int main( int argc, const char *argv[] ) {
-
- Fraction *frac = [[Fraction alloc] init];
-
-
- int x;
- int y;
-
-
- [frac setNumerator: 1];
- [frac setDenominator: 3];
-
-
- printf( "The fraction is: " );
-
- [frac print];
- printf( "/n/n" );
- NSLog(@"hello world!!!/n");
-
- [frac setNumerator:34 ddd: 98];
-
- [frac print];
- printf( "/n/n" );
- NSLog(@"hello world world!!!/n");
-
- [frac setNumerator:44 : 55 :66];
- [frac print];
- printf( "/n/n" );
-
- scanf("%d %d", &x,&y);
-
- [frac setNumerator: x ddd: y];
- [frac print];
-
-
- [frac release];
-
-
-
- return 0;
- }
编译方法:
1)将main.m编译成main.o :
gcc -fconstant-string-class=NSConstantString -c main.m -I /GNUstep/System/Library/Headers
2) 将Fraction.m编译成Fraction.o :
gcc -c Fraction.m -I /GNUstep/System/Library/Headers
3) 将.o编译成可执行程序,名为main(最后生成的是main.exe)
gcc -o main main.o Fraction.o -L /GNUstep/System/Library/Libraries/ -lobjc -lgnustep-base
注意:这时会有warning出现,但可以不用管它,毕竟,我们的可执行程序已经编译出来了.
运行结果:
- samsung@coco ~/objc/fraction
- $ ./main.exe
- The fraction is: 1/3
-
- 2010-08-13 16:29:01.515 main[1212] hello world!!!
- 34/98
-
- 2010-08-13 16:29:01.515 main[1212] hello world world!!!
- +++++a = 66 +++
- 44/55
-
- 22 33
- 22/33
