While building an existing code base on Mac OS using its native build setup I am getting some basic strange error while compilation phase.
Does any of you have any idea, as I have seen it’s been discussed earlier as well in this forum without any good reason. I can not see any conflicting files being included.
But still I am unable to compile the code because this error appears.
Source are like the code given below and compilation error appears
$ cat a.h
#include <string>
#include <sstream>
namespace brijesh {
typedef std::string String;
template<class T>
String toString(T value) {
std::ostringstream buffer;
buffer << value;
return buffer.str();
}
$ cat b.h
#include "a.h"
namespace brijesh {
class Platform {
public:
static String getName();
};
}
$ cat b.cpp
#include "b.h"
namespace brijesh {
String Platform::getName()
{
String name = "UNKNOWN";
#ifdef LINUX
name = "linux";
#endif
#ifdef MACOSX
name = "Mac";
#endif
return name;
}
}

It looks like you’re trying to use OS X 10.3 developer tools (Xcode et al) and are trying to target OS X 10.4, which is obviously not going to work. Either change your build command to remove incompatible flags, such as
-mmacosx-version-min=10.4, or upgrade to a more current version of OS X + Xcode + SDKs.
