objective-c - 无法使用 GNUstep 在 Objective-C 上构建程序

Question

我正在尝试在 Linux (Ubuntu) 的 Objective-C 上构建 hello world。主程序

#import <Foundation/Foundation.h>

int main(void)
{

    NSLog(@"asdasd");  
    return 0;
}

我不认为这里有错误。然后我创建了 Makefile:

GNUSTEP_MAKEFILES = /usr/share/GNUstep/Makefiles

include $(GNUSTEP_MAKEFILES)/common.make
TOOL_NAME = main
main_OBJC_FILES = main.m
include $(GNUSTEP_MAKEFILES)/tool.make

然后我运行“make”:

This is gnustep-make 2.2.0. Type 'make print-gnustep-make-help' for help.
Making all for tool main...
make[1]: GNUmakefile: no such file or directory

我该如何解决？

Answer 1

在 Ubuntu 系统上安装 GNUstep 库和工具很简单，只需 sudo apt-get install gnustep gnustep-devel 就可以了(说真的，据我所知，Apt 是安装软件最简单的方法- 只要它在存储库中)。结果我将其命名为 GNUMakefile，而我应该将其命名为 GNUmakefile。

source.m:

#import <Foundation/Foundation.h>
int main(void)
{
    NSLog(@"asdasd");  
    return 0;
}

GNUmakefile:

GNUSTEP_MAKEFILES = /usr/share/GNUstep/Makefiles

include $(GNUSTEP_MAKEFILES)/common.make
TOOL_NAME = app
app_OBJC_FILES = source.m
include $(GNUSTEP_MAKEFILES)/tool.make

我可以运行它。
