I modified my project and after compiling there pop up some weird error.

#ifndef BART_RAY_TRACER_MESH_H
#define BART_RAY_TRACER_MESH_H

#include <vector>
#include "assert.h"
#include "vec3f.h"

class Triangle;

class Mesh {
public:
    uint32_t nverts;
    bool _is_static;
    vec3f *verts;
    vec3f *_verts_world;
    Material material; 
    // 2 error occurs at the line below
    Matrix4x4 _trans_local_to_world; // '_trans_local_to_world': unknown override specifier & missing type specifier - int assumed. Note: C++ does not support default-int
    Matrix4x4 _trans_local_to_world_inv;
    TransformHierarchy *_trans_hierarchy;   

    std::vector<Triangle* > triangles;
    // ...
};
#endif

When I change the order of the declaration a little bit, the error always occurs the line after Material material, but with different message:

#ifndef BART_RAY_TRACER_MESH_H
#define BART_RAY_TRACER_MESH_H

#include <vector>
#include "assert.h"
#include "vec3f.h"

class Triangle;

class Mesh {
public:
    uint32_t nverts;
    bool _is_static;
    vec3f *verts;
    vec3f *_verts_world;
    Material material; 
    // 2 error occurs at the line below
    TransformHierarchy *_trans_hierarchy; // error C2143: syntax error: missing ';' before '*' & error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
    Matrix4x4 _trans_local_to_world;
    Matrix4x4 _trans_local_to_world_inv;  

    std::vector<Triangle* > triangles;
    // ...
};
#endif

I’ve searched for similar questions on SO but none seems useful.
I’ve checked my vec3f, Triangle class definition in case there are missing semicolons but I can’t find any.

Can any one help?

This is just another Microsoft cock-up. Here it is in essence:

class C
  {
  x y ;
  } ;

If you submit this to a sensible compiler like g++, it gives you a helpful error message:

3:2: error: ‘x’ does not name a type

MSVC, on the other hand, comes up with this gibberish:

(3): error C3646: ‘y’: unknown override specifier
(3): error C4430: missing type specifier — int assumed. Note: C++ does not
support default-int

With this key, you can decrypt Microsoft’s error message into:

error: ‘Matrix4x4’ does not name a type

The error is most likely because that TransformHierarchy and Matrix4x4 are not defined.

If they are not defined in "assert.h" and "vec3f.h", this should be the case.

Forward declaration is enough only when you use the reference types and/or pointer types only. Therefore, to forward declare Triangle is OK. But forward declare Triangle does not mean your shape.h is processed. Neither does your material.h which is included in shape.h.

Therefore, all names in material.h is not visible from this code.
TransformHierarchy and Matrix4x4 are not recognized by the compiler.
Many of the compliers will complain with words similar to "missing type specifier - int assumed"

In my case, it was found that a header file had the following directives for a class [ie, myComboBoxData]

#ifndef __COMBOBOXDATA__
#define __COMBOBOXDATA__
// ... 
class myComboBoxData
{
    // ...
}
#endif

As another class below tried to use myComboBoxData class

class TypeDlg : public CDialog
{
    myComboBoxData cbRow,cbCol;
    // ...
}

the error message popped up as above:

«error C3646: ‘cbRow’: unknown override specifier».

Solution:

The problem was the directive name (__COMBOBOXDATA__) was already used by OTHER header.

Thus, make sure to use some other name like (__myCOMBOBOXDATA__).

I use Visual Studio 2015 and I have a C# Application-Project that defines a COM-Interface and generates a .tlb file on compilation. Now I want to import that Csharp.tlb into an idl.

MyLibrary.idl:

import "oaidl.idl";
import "ocidl.idl";
import "Cplusplus.idl";

library MyLibrary
{
  importlib("stdole32.tlb");
  importlib("stdole2.tlb");
  importlib("Csharp.tlb");

  interface IMyCOM : IDispatch
  {
    [propget, id(1)]
    HRESULT CpluplusObject
    (
      [out,retval] ICplusplusObject** cplusplusObject
    );

    [propget, id(2)]
    HRESULT CsharpObject
    (
      [out, retval] ICsharpObject** csharpObject
    );
  }

  coclass MyCOM
  {
    [default] interface IMyCOM;
  };
}

During compilation I get an error

C3646 ‘csharpObject’: unknown override specifier in MyLibrary.tlh

MyLibrary.tlh was auto generated by the compilation and looks as the following

MyLibrary.tlh:

#pragma once
#pragma pack(push, 8)

#include <comdef.h>

namespace MyLibrary {

  struct __declspec(uuid("8e664998-bc93-48e7-adcc-84fc8598cd5d"))

  }

  __declspec(implementation_key(1)) ICplusplusObjectPtr IMyLibrary::GetcplusplusObject ( );
  __declspec(implementation_key(2)) ICsharpObjectPtr IMyLibrary::GetcsharpObject ( );
}

The error means that ICsharpObjectPtr or ICsharpObject respectively is not known which I understand so far. ICplusplusObjectPtr is known because import «ICplusplus.idl» added the definitions into the .tlh and importlib(«ICsharp.tlb»); did not obviously.

For Test reasons I generated the ICsharp.idl out of the .tlb by using OLE/COM Object Viewer and made an import of that idl. The error was gone after that.

But why does the importlib of the .tlb not work directly? I do not want to generate an idl file every time out of the .tlb.

I think that there is an #include «ICsharp.tlh» missing or something to make the type known for the .tlh. But how to tell the idl or the compiler to properly reference the ICsharpObject?

Thank you so much in advance for your help.

Я пытаюсь написать простой движок DirectX11, но продолжаю получать эту странную ошибку и не могу найти проблему: я определяю класс Terrain и класс Mesh и #include класс Mesh в классе Terrain:

определение класса Terrain:

// Terrain.h
#pragma once

#include "Noise.h"#include "Mesh.h"
class Terrain
{
public:
Terrain(float width, float depth, int numVerticesW, int numVerticesD);
~Terrain();
float GetHeight(float x, float z);
void Draw();
private:
Mesh mMesh;                     // I get the error on this line
Noise mNoiseGenerator;
std::vector<float> mHeights;
void CreateTerrain(float width, float depth, int numVerticesW, int numVerticesD);
float ComputeHeight(float x, float z, float startFrequency, float startAmplitude, float persistence, int octaves);
};

и определение класса Mesh:

// Mesh.h
#pragma once

#include <d3d11.h>
#include <vector>
#include "Game.h"
class Mesh
{
public:
Mesh();
~Mesh();
template <typename T, unsigned int N>
void LoadVertexBuffer(T data[][N], unsigned int size, bool dynamic = false);
void LoadIndexBuffer(std::vector<unsigned int> indices);
void SetVertexCount(unsigned int vertexCount);
void Bind();
void Draw();
private:
std::vector<ID3D11Buffer*> mVertexBuffers;
std::vector<unsigned int> mStrides;
ID3D11Buffer *mIndexBuffer;
unsigned int mVertexCount;
};template <typename T, unsigned int N>
void Mesh::LoadVertexBuffer(T data[][N], unsigned int size, bool dynamic)
{
D3D11_BUFFER_DESC bufferDesc = {};
bufferDesc.Usage = dynamic ? D3D11_USAGE_DYNAMIC : D3D11_USAGE_IMMUTABLE;
bufferDesc.BindFlags = D3D11_BIND_VERTEX_BUFFER;
bufferDesc.ByteWidth = sizeof(T[N]) * size;
bufferDesc.CPUAccessFlags = dynamic ? D3D11_CPU_ACCESS_WRITE : 0;
bufferDesc.MiscFlags = 0;
bufferDesc.StructureByteStride = 0;

D3D11_SUBRESOURCE_DATA bufferData = {};
bufferData.pSysMem = data;

ID3D11Buffer *buffer;
Game::GetInstance()->GetDevice()->CreateBuffer(&bufferDesc, &bufferData, &buffer);
mVertexBuffers.push_back(buffer);
mStrides.push_back(sizeof(T[N]));
}

Когда я компилирую код, я получаю:

Severity    Code    Description Project File    Line    Suppression State
Error   C3646   'mMesh': unknown override specifier DirectX11 engine 0.3    c:userslucadesktopprogrammingcodec++sourcevisual studiodirectx11 engine 0.3terrain.h  14

Я искал в Интернете, но большинство результатов показывают пропущенные точки с запятой или циклические проблемы с включением, но я не могу их найти.

РЕДАКТИРОВАТЬ
Я обнаружил проблему, но не могу объяснить, почему мое решение работает:
следуя дереву включения:
Terrain.h -> Mesh.h -> Game.h -> Renderer.h -> Terrain.h

устранение #include «Terrain.h» (поскольку я просто объявляю указатели Terrain * внутри класса) и добавление его в Terrain.cpp, похоже, решает проблему.
Так что, должно быть, речь идет о круговом включении, но разве я не должен быть защищен от этого с помощью защиты заголовка / включения?

1

Решение

Ваша проблема в том, что #pragma once предотвращает только двойное включение. То есть это делает следующее безопасным (упрощенным, чтобы сделать это очевидным):

// Terrain.cpp
#include "Terrain.h"#include "Terrain.h"

Это не решает круговое включение, которое гораздо сложнее решить автоматически. С двойным включением понятно, кто из них первый. Но у круга нет начала.

dbapserv.h(451): error C3646: ‘final’ : unknown override specifier


I am compiling a 2014 x64 ARX with the 2015 SDK, and receive the following error:

Does anyone know where I should be looking to solve this issue ?

You have to build with VS 2012 Update 4.

That was applied before I started:

It’s not enough to use the VS 2012 IDE, you also have to set the correct Platform Toolset in the project properties.

Doesn’t matter, either one:

Platform Toolset: Visual Studio 2010 (v100)
Platform Toolset: Visual Studio 2012 (v110)

Returns the error. Is there some specific setup documentation for VS 2012 ? I didn’t notice it in the SDK.

Can you reproduce the problem in a new project created from scratch? If so, attach it here so I can have a look. I’m not sure I understand your question about documentation. As far as I know, all the SDK documentation is in the docs subdirectory.

I have this happening in 3 older working MFC Extension Arx projects; so I find it is easy to reproduce in a fresh 2014 Wizard generated project’s code:

Why exactly it does, is not clear yet.

I haven’t tried to build your project, just looked through it. I see that it imports Autodesk.arx-2014.props. Where does that file come from? Did you edit it?

The 2014 Wizard creates it, it appears to be irrelevant to the compiler issue with the .h file.

I can confirm the error when I build your project. I don’t see any obvious reason, but I’ll have a closer look when time permits.

Ah, I see the problem. In your project file around line 53, you are overriding the PlatformToolset property. I deleted those property overrides, saved the file, then reloaded it in the IDE and reset the platform toolset — now it builds without error.

I’m not following your comments.

I didn’t override the PlatformToolset. But even when I remove from the TestArxProject1.vcxproj file those lines, so it looks like this:

  <PropertyGroup Label=»Configuration»>
  </PropertyGroup>

And reset the PlatformToolset correctly I still end up with an error. It also does not help when I edit the Autodesk.arx-2014.props file from:

        <ArxSDKVersion>19.1</ArxSDKVersion>
        <ArxSDKPlatform>v100</ArxSDKPlatform>

to this:

        <ArxSDKVersion>20.0</ArxSDKVersion>
        <ArxSDKPlatform>v110</ArxSDKPlatform>

I am compiling a 2014 x64 ARX with the 2015 SDK, and receive the following error:

Does anyone know where I should be looking to solve this issue ?

You have to use ObjectARX SDK 2014 (not 2015) in order to create arx-application for AutoCAD 2014

I’ve attached the project file that builds without error for me. I also removed the /WX compiler option while messing around with it, so maybe something else I changed also affects the outcome.

Sorry I wasn’t clearer, but I am not interested in compiling for 2014.

I am compiling for 2015. As the test example shows.

I didn’t expect to have so much trouble doing that with code which works and compiles for 2014.

The error appears to be with the 2015 SDK and the 2012 compiler settings as setup using the 2014 Wizard.

Yes that works. I’ll need to look at this more closely. I thought I had those setting changed per your project, but apparently not all of them.

Actually — in addition to the corrected Platform settings, they have to be placed in the .vcxproj in the right location. When I moved the PlatformToolset lines to the location yours were right below the PropertyGroup Condition :

  <PropertyGroup Condition=»‘$(Configuration)’==’Release'» Label=»Configuration»>
    <UseDebugLibraries>false</UseDebugLibraries>
    <WholeProgramOptimization>true</WholeProgramOptimization>
  </PropertyGroup>
  <PropertyGroup Condition=»‘$(Configuration)’==’Debug'» Label=»Configuration»>
    <UseDebugLibraries>true</UseDebugLibraries>
    <WholeProgramOptimization>false</WholeProgramOptimization>
  </PropertyGroup>

  <PropertyGroup Label=»Configuration» Condition=»‘$(Configuration)|$(Platform)’==’Debug|Win32′»>
    <PlatformToolset>v110</PlatformToolset>
  </PropertyGroup>
  <PropertyGroup Label=»Configuration» Condition=»‘$(Configuration)|$(Platform)’==’Release|Win32′»>
    <PlatformToolset>v110</PlatformToolset>
  </PropertyGroup>
  <PropertyGroup Label=»Configuration» Condition=»‘$(Configuration)|$(Platform)’==’Debug|x64′»>
    <PlatformToolset>v110</PlatformToolset>
  </PropertyGroup>
  <PropertyGroup Label=»Configuration» Condition=»‘$(Configuration)|$(Platform)’==’Release|x64′»>
    <PlatformToolset>v110</PlatformToolset>
  </PropertyGroup>

Then my project file worked to compile, otherwise it doesn’t properly configured.
