Question

当我使用g++

编译以下代码时

#include <CoreServices/CoreServices.h>
int main(int argc, char ** argv)
{
  return 0;
}

我收到此错误。

bash-3.2$ g++ test.C
In file included from /System/Library/Frameworks/CoreFoundation.framework/Headers/CoreFoundation.h:43:0,
                 from /System/Library/Frameworks/CoreServices.framework/Frameworks/CarbonCore.framework/Headers/CarbonCore.h:20,
                 from /System/Library/Frameworks/CoreServices.framework/Frameworks/AE.framework/Headers/AE.h:20,
                 from /System/Library/Frameworks/CoreServices.framework/Headers/CoreServices.h:21,
                 from test.C:1:
/System/Library/Frameworks/CoreFoundation.framework/Headers/CFBundle.h:147:120: error: format string argument not a string type

有谁知道我能做些什么才能让它发挥作用？我正在尝试使用mach_absolute_time和AbsoluteToNanoseconds CoreServices.h，here。

g++ -v
gcc version 4.5.0 20100107 (experimental) (GCC)

看起来你正在尝试使用Apple的框架而不使用Apple的工具链 - 这可能不会起作用。你的示例程序在这里为我编译好，使用Xcode附带的gcc（和clang）：

$ cat example.cpp 
#include <CoreServices/CoreServices.h>
int main(int argc, char ** argv)
{
  return 0;
}
$ make example
g++     example.cpp   -o example
$ rm example
$ CXX=clang make example
clang     example.cpp   -o example
$

Mac OS X上的g ++ - CoreServices.h错误
