Compiler cannot resolve type definition

[kribel]

Hello all,

I am getting the following error compiling my project:

D:\.../src/engine/Plugin.hpp:78:21: error: 'engineVersion_t' does not name a type

I defined engineVersion_t in engine.hpp which looks as followed:

#ifndef ENGINE_HPP_
#define ENGINE_HPP_

#include <global/dataTypes.hpp>

namespace tradingScreener
{
	namespace engine
	{
		struct engineVersion_t
		{
			uint16 main;
			uint16 release;
			uint16 bugfix;
		};

	} // namespace engine

} // namespace tradingScreener

#endif /* ENGINE_HPP_ */ 

Plugin.hpp includes engine.hpp and looks as followed:

#ifndef PLUGIN_HPP_
#define PLUGIN_HPP_

#include <string>
#include <engine/engine.hpp>

#define WIN32_LEAN_AND_MEAN
#include <windows.h>

namespace tradingScreener
{

	namespace engine
	{
		class Core;

		class Plugin
		{
			...
			public:
				engineVersion_t getEngineVersion() const;
		};

	} // namespace engine

} // namespace tradingScreener

#endif /* PLUGIN_HPP_ */ 

Can somebody help me to get my head around this issue? Why the compiler cannot resolve the data type?

Many thanks,
Konstantin

You need to fully qualify engineVersion_t with: tradingScreener::engine.

On a side note, the _t suffix is reserved for UNIX system implementations. I know you're on Windows, but I thought you would like to know :)

@kribel
The code you have posted doesn't show what is wrong. There must be something else going on that you have not shown us.

@Framework
He should not have to specify tradingScreener::engine because it's defined in the same namespace.

Hi Peter87, Framework,

@Framework:
I tried your suggestion, unfortunately it did not work. The following error appeared instead:

D:\.../src/engine/Plugin.hpp:78:21: error: 'engineVersion_t' in namespace 'tradingScreener::engine' does not name a type

I also tried ::tradingScreener::engine::engineVersion_t and it did not work out.

@Peter87:
You are absolutely right. There must be something somewhere else. Lets have a deeper look into the project.

engine.hpp is included in the following files:
- Plugin.hpp (for content of this file please see the 1st post)
- GeneralPlugin.hpp

Content of GeneralPlugin.hpp:

#ifndef GENERALPLUGIN_HPP_
#define GENERALPLUGIN_HPP_

#include <boost/property_tree/ptree.hpp>
#include <engine/engine.hpp>
#include <global/dataTypes.hpp>

namespace tradingScreener
{
	namespace engine
	{

		typedef std::string property_t;

		class GeneralPlugin
		{
			public:
				virtual ~GeneralPlugin() = 0;

				virtual std::string getName() const = 0;
				virtual engineVersion_t getPluginVersion() const = 0;
				virtual std::string getPluginDescription() const = 0;
				virtual boost::property_tree::ptree getPluginProperties() const = 0;
				virtual void setPluginProperties(boost::property_tree::ptree properties) = 0;
				virtual std::string getPropertyDescription( property_t property, languageCode_t languageCode) const = 0;
		};

	} // namespace engine

} // namespace tradingScreener

#endif /* GENERALPLUGIN_HPP_ */
