C2143

T RATHA KRISHNAN

Hi! I'm Working in a VC++ Simulation project. I've got an error which says, c:\program files\delta3d_rel-2.0.0\inc\dtcore\globals.h(29) : error C2143: syntax error : missing ';' before 'namespace' globals.h is a Delta3D Simulation Engine's file. I did not touch it at all. What might be the problem? What is the resolution?

toxcct

the problem might be because you have a syntax error (a missing ; or a brackets { } misplaced) before #including globals.h

I didn't miss any ';' at all. Infact it's system(Simulation Engine's) file. What to do? Here is the complete code for globals.h.

#ifndef DELTA_GLOBALS
#define DELTA_GLOBALS

#include <string>

#include <dtCore/export.h>

namespace dtCore
{
/// Set the list of data file paths
DT_CORE_EXPORT void SetDataFilePathList( const std::string& pathList );

/// Get the list of data file paths
DT_CORE_EXPORT std::string GetDataFilePathList();

/// Get the Delta Data path list (equivalent to the DELTA_DATA environment)
DT_CORE_EXPORT std::string GetDeltaDataPathList();

/// Get the root path to Delta3D (equivalent to the DELTA_ROOT environment)
DT_CORE_EXPORT std::string GetDeltaRootPath();

/// Convienence method to get the supplied environment variable
DT_CORE_EXPORT std::string GetEnvironment(const std::string& env );

  DT\_CORE\_EXPORT void SetEnvironment(const std::string& name, const std::string& value);

 DT\_CORE\_EXPORT std::string FindFileInPathList(const std::string &fileName);

}

#endif //DELTA_GLOBALS

so you didn't read my post !!! i said the error is NOT in the globals.h file itself but around it. when you #include a header, it's as if its content was copied/pasted at the location of the #include directive. so if you have an arror in a file #included before that one, on in the including file itself, you might see such errors in files you actually didn't modified. also, if it's a system file, be sure to #include **<>** rather than #include **""**

Here is my complete listings where the 'globals.h' is included.

#include "HelloWorld.h"
#include <dtCore/globals.h>
#include <dtCore/object.h>
#include <dtCore/orbitmotionmodel.h>
#include <dtCore/scene.h>
#include <osgDB/FileUtils>
#include <dtCore/dt.h>
#include <dtABC/application.h>

If include HelloWorld.h like u said () it shows me error which says Cannot open include file. No such file or Directory. What to do?

CPallini

I can't believe HelloWorld.h being a system header. BTW usually non-system headers includes (like #include "HelloWorld.h") follows the system ones. Your snippet shows the opposite. :)

toxcct

what happens if you #include "HelloWorld.h" after every other system includes ?

[VisualCalc][Binary Guide][CommDialogs] | [Forums Guidelines]

T RATHA KRISHNAN

Not HelloWorld.h. It's globals.h.

CPallini

I was suggesting (the same toxcct did) to put #include "HelloWorld.h" at the end of your include list. Often problems originate in slightly different places with respect the one the misbehaviour shows up. :)

It gives me errors if I include after all the system files. d:\myprojects\myprojects\myprojects\helloworld.cpp(13) : error C2533: 'HelloWorld::{ctor}' : constructors not allowed a return type d:\myprojects\myprojects\myprojects\helloworld.cpp(65) : error C2264: 'HelloWorld::HelloWorld' : error in function definition or declaration; function not called

CPallini

Please post the code. :)

Then it probably means you have errors in that file. Post some code (and please, use the code block tags).

Well, I cannot spot the error. The code seems OK. Anyway, I insist, the right place for #include "HelloWorld.h" is at the bottom of the list. :)

you're missing a ; after the closing } of the class definition. a class definition is like this :
