Ubuntu下Objective-C開發環境搭建

1.Installing GNUstep on Ubuntu

       下面列出來的包是安裝GNUstep環境所必須的：

• build-essential
• gobjc
• gobjc++
• gnustep-devel

用 apt-get install 就可以搞定

2.編譯objective-c代碼

 #import <Foundation/Foundation.h>

int main (int argc, const char * argv[])
{
        NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

        NSLog (@"hello world");
        [pool drain];
        return 0;
}

保存爲 hello.m.

.  /usr/share/GNUstep/Makefiles/GNUstep.sh

gcc -fconstant-string-class=NSConstantString -o hello hello.m -I/usr/include/GNUstep  -lobjc -lgnustep-base

./hello 運行出結果

matsyx@matsyx-pc:~/Downloads/obj-c_text$ ./hello
