Hi David,
I recently hit these errors from #include<string> when I added
/usr/include/sys to my header search paths (rdar://5997145).
What are your header search paths?

I added an explicit include statement (#include <string>). Now, I get
this error:
Time.h:26:18: error: string: No such file or directory
I also get a new set of errors before this one occurs. These are coming
from the file "ctime" in the C++ library:
/Developer/SDKs/MacOSX10.4u.sdk/usr/include/c++/4.0.0/ctime:68: error:
'::tm' has not been declared
The code it's referring to looks like this:
namespace std
{
using ::clock_t;
using ::time_t;
using ::tm;
I get this in the pre-compiling headers stage - there are lots of
others, also for ::namespaces that are missing. It's coming from a file
that is part of the SDK.
It seems like these errors may be related, but I'm not sure how- any
help is appreciated.
Thanks,
David

Time.h:47: error: 'string' in namespace 'std' does not name a type
The code in question looks like this:
static std::string local( const time_t& iTime );
This compiles without a problem on Linux - only XCode throws the
error. I suspect it might be happening because I'm not supplying a
link command, e.g., to a libstdc++ dynamic library.
It's a compiler error, which means you haven't gotten to the link
phase, so it has nothing to do with your libraries. Most likely you
don't have a "#include <string>" in your file. If it compiles on
Linux, that just means that something in the Linux headers is
including <string> for you.
