typedef Syntax Error

[Mike Copeland]

I'm getting a syntax error on the "typedef" code line here. Any
thoughts on why? TIA
struct CSTYPE
{ // City/State Record
string csKey; // City/State "Key"
string csCity; // City
string csState; // State Code
};
typedef map<string, CSTYPECSINFO; // <=== error here
extern CSINFO cityStInfo;
extern map<string, CSTYPE>::iterator csIter;
extern CSTYPE workCS;

1. did you #include <mapand <string>?
2. map and string live in the std:: namespace
3. Would you care to describe the specific error?

It's possible that his compiler does not allow the use of incomplete
types as template arguments, even in typedefs, and 'CSTYPE' is
incomplete at that point...

The following appears to work as expected w/GCC 4.

#include <map>
#include <string>

using std::map;
using std::string;

// TODO: Expand "cs" to something more meaningful.
namespace cs {

// TODO: Give this type a more meaningful name.
struct type {
string key;
string city;
string state;
};

typedef map<string, typeinfo;
}

#include <iostream>

int main() {

cs::info info;

info["hello"].key = "world";
info["foo"].key = "bar";

std::cout << info["hello"].key << '\n';
std::cout << info["foo"].key << '\n';
}

Yes, but please see my common above. I _thought_ I had a complete
declaration for CSTYPE - am I wrong?

I didn't state the error (C2143) because it's compiler-specififc
(VC++ 6.0) and I know that's a no-no here. 8<{{

That wasn't the case in his original code. If you'll look at
the end of the line "string csState;", you'll see the closing
brace of CSTYPE. For some reasons, something in the news very
often seems to move a line with just a }: to the end of the
preceding line. (I've always suspected Google, because that's
what I use to read news, and I'm constantly seeing this.)

Without the closing brace, of course, the code would be illegal.
Because of the incomplete type, but also because you're not
allowed to use extern in a class either (and that error requires
a dignostic).

Like Mike, I rather suspect that he's either forgotten the
include, and he's clearly fogotten the std::. Which means that
string and map are unknown symbols. To reasonably parse C++,
the compiler needs to know when a symbol names a type; use an
unknown symbol where a type is required, the compiler will
generally suppose it isn't a type (which results in a syntax
error), and the quality of the error messages go downhill from
there.

You did. Your original posting was correct in this regard, but
something in the net seems to occasionally (often, in fact) join
a line with just a "}" or a "};" with the preceding line. If
the preceding line doesn't end with a comment, it doesn't affect
the legality of the code, but it is an unusual formatting. (I
asked about this once, since I was seeing so many postings with
this unusual formatting, and thought it might be some new coding
convention I wasn't familiar with. The poster in question
assured me that the }; was on a separate line when the posting
left his machine.)

There is no reason I know of to use VC++ 6.0 when you can download VC++ 8.0
for free from Microsoft which is much better and up to date. See here.

That's VC9 even, telling us that VC6 is just ancient. Don't use it

But you could tell us the *text* of the message, which might shed some
light. ;-)

Another possibility that nobody has mentioned is that you're including
some other header file which defines CSINFO or CSTYPE as a macro -
because of this, it's often a good idea to avoid using all-caps
identifiers for anything else.

I also didn't state that this is in a common .h file I'm building

The message is "syntax error : missing 'token1' before 'token2'",
which could be helpful in understanding your problem.

Sounds like one of the headers included before this screwed up.
Have your file preprocessed and compile the result. Check what's
just above the definition of 'CSTYPE'. (If it still /is/ 'CSTYPE'
after preprocessing.)
