使用 GNUstep 编译 Objective-C
我是 Objective-C 的新手。我正在尝试使用 GNUstep 编译 Objective-C，但出现错误。我尝试在命令行（gcc 和 makefile）上进行编译。
No such file or directory /
excepted '>' before 'GSPredicateBlock'
…
我使用了命令行
gcc gnustep-config --objc-flags -o hello hello.m -I /GNUstep/System/Library/Headers -L /GNUstep/System/Library/Libraries -lobjc -lgnustep-base -fconstant-string-class=NSConstantString -enable-auto-import
我尝试使用makefile：
Making all for tool Hello...
Compiling file hello.m ...
hello.m:1:71 fatal error: ../../GNUstep/System/Library/Headers/Foundation/Found ation.h: No such file or directory
compilation terminated.
make[3]: *** [obj/Hello.obj/hello.m.o] Error 1
make[2]: *** [internal-tool-all_] Error 2
make[1]: *** [Hello.all.tool.variables] Error 2
make: *** [internal-all] Error 2
我搜索了Google，但找不到任何有帮助的东西。我安装了 gnustep-msys-system-0.28.0-setup、gnustep-core-0.28.0-setup 和 gnustep-devel-1.3.0-setup在 Windows 7 上。
I'm a newbie in Objective-C. I'm trying to compile Objective-C with GNUstep but it's giving errors. I tried to both compile on command line (gcc and makefile).
No such file or directory /
excepted '>' before 'GSPredicateBlock'
…
I used the command line
gcc gnustep-config --objc-flags -o hello hello.m -I /GNUstep/System/Library/Headers -L /GNUstep/System/Library/Libraries -lobjc -lgnustep-base -fconstant-string-class=NSConstantString -enable-auto-import
My attempt at using a makefile:
Making all for tool Hello...
Compiling file hello.m ...
hello.m:1:71 fatal error: ../../GNUstep/System/Library/Headers/Foundation/Found ation.h: No such file or directory
compilation terminated.
make[3]: *** [obj/Hello.obj/hello.m.o] Error 1
make[2]: *** [internal-tool-all_] Error 2
make[1]: *** [Hello.all.tool.variables] Error 2
make: *** [internal-all] Error 2
I've searched Google, but I can't find anything that helps. I installed gnustep-msys-system-0.28.0-setup, gnustep-core-0.28.0-setup and gnustep-devel-1.3.0-setup on Windows 7.

我不知道这是否是一个红鲱鱼，但我看到在不应该出现的地方有一个空格：
它应该在源代码文件中读取：（
没有空格）
显然这是编译器在这里抱怨的：
删除源代码文件的导入指令中的空格，然后重试。
I don't know if this is a red herring but I see there's a space in a place where it should not be:
it should read:
(without the space) in your source code file
Obviously this is what the compiler complains about here:
remove that space in your source code file's import directive and try again.
