I'm trying to compile a VS 2010 project that uses GTK2.22. I added the all-in-one packages, include paths and libraries but there is still over a thousands errors.
As an example, here are a few of them:
gdkcolor.h:
struct _GdkColormap
{
GObject parent_instance;
gint GSEAL (size);
GdkColor *GSEAL (colors);
GdkVisual *GSEAL (visual);
gpointer GSEAL (windowing_data);
};
error C2061: syntax error : identifier 'size' 'colors' 'visual' and 'windowing_data'
My guess is that some OS related dependency is missing but I have no idea which one. Anyone has an idea what could it be?

I'm writing a new project and want to replace GLEW with glbinding.
My setup is like this:
VS 2015, Qt 5.6, glbinding 2.0
I tried to compile quite simple code - only window (QWindow) with OpenGL context (QOpenGLContext) but got an error: glbinding is not compatible with gl.h
When I was tracking this bug I found out that file (which is imported by the glbinding/gl/gl.h) nogl.h is causing this message with the code below:
#ifdef __gl_h_
#error "glbinding is not compatible with gl.h"
#else
#define __gl_h_
#endif
Then I noticed that this is caused by the QtGui/qopenglcontext.h header (which I need for creating OpenGL context...). So when I don't include qopenglcontext.h my program compiles without error. I also noticed that this error message appears only when I include glbinding/gl/gl.h after QtGui/qopenglcontext.h. If I reverse the include order I get a bunch of errors like this:
1>C:\Qt\Qt5.6.0\5.6\msvc2015_64\include\QtGui/qopenglext.h(117): error C2065: 'GLenum': undeclared identifier
1>C:\Qt\Qt5.6.0\5.6\msvc2015_64\include\QtGui/qopenglext.h(117): error C2146: syntax error: missing ')' before identifier 'mode'
1>C:\Qt\Qt5.6.0\5.6\msvc2015_64\include\QtGui/qopenglext.h(118): error C2065: 'GLenum': undeclared identifier
1>C:\Qt\Qt5.6.0\5.6\msvc2015_64\include\QtGui/qopenglext.h(118): error C2146: syntax error: missing ')' before identifier 'target'
After all I still don't know how to solve this and what exactly is causing this error...
glbinding – like practically every other OpenGL loader – has to fiddle with the OpenGL symbol tokens to avoid namespace clashing. To this end it must interact with the OpenGL definitions in a specific way, which means you must not have included any OpenGL header, or something that includes such in turn at the moment you include the glbinding header. The preprocessor fiddling glbinding performs will prevent gl.h getting included in a way that causes trouble.
So what you must do is: Include the glbinding headers in your C++ compilation unit files before everything else (Qt headers, OpenGL helper libraries and so on).
I'm trying to execute a code generated by graphEditPlus (using VS2010) but having a trouble with the following line:
CComQIPtr<ISampleGrabber, &IID_ISampleGrabber> pSampleGrabber_isg(pSampleGrabber);
where the errors are:
error C2065: 'ISampleGrabber' : undeclared identifier
error C2065: 'IID_ISampleGrabber' : undeclared identifier
error C2514: 'ATL::CComQIPtr' : class has no constructors
I tried downloading different versions of Windows SDK (V7.1, V6.0A, V5) and set the include / lib paths but still having the same problem!
Is the SampleGrabber still being supported? Mainly, the SampleGrabber is used in my code to grab frames from a video capturing source...
Thanks for your assistance...
Microsoft deprecated Sample Grabber and the entire DES API, however you if you import the type library, or just copy the declarations into your project - the component is still usable except some very latest OS releases (Windows Server 2008?) where it is completely gone and you might need another solution such as building your own from earlier SDK samples.
See ISampleGrabber deprecated: where can I find alternatives? for more information.
See also RenderWmvVideo.cpp with code fragment to copy/paste and re-add the declarations to your project (#pragma section at the top of the file):
#pragma region Windows SDK Tribute, qedit.h

I want to make a Google Chrome plugin that use Twain to remote control a Digital Camera.
I want this to run on Windows and I'm using Visual Studio Express 2012 C++.
I have this sample for NPAPI and this sample of CppWrapper for Twain which has 3 interesting files (TwainCpp.cpp TwainCpp.h twain.h)
Before doing anything, I want to merge these two projects.
First step: putting twain.h in the npsimple project which failed, twain.h errors caught.
Second step: putting CppTwain in npsimple, which also failed because twain.h "contains" errors.
Problem is that when I create an empty project, and put twain.h in it, there is no error! So I tried to put npsimple files in that empty project, and this time I get error from npsimple files..
Error type :
I have this code in twain.h :
#ifdef _MSWIN_
typedef HANDLE TW_HANDLE;
typedef LPVOID TW_MEMREF;
and I get plenty of errors like :
error C2146: syntax error : missing ';' before identifier 'TW_HANDLE'
How can I merge these projects?
HANDLE is an unspecified type because you don't include anything that is specificing it. You'll want to include windows.h.
Obviously there is no error when you add only the twain.h header file to the empty project - you haven't added any sources to compile, hence there can be no compilation errors.
I'm building a big C++ project on Visual Studio 2008 I'm getting this error message and I don't understand it. Is it a failure to include the .h file?
I know this thread is dated, but I had the exact same problem with a C++ project on Visual Studio 2008, here was my resolution...
One of the things the VS2008 compile told me was that it generated a log on:
"file://C:\Documents and Settings\adam\My Documents\Visual Studio 2008\Projects\MyProject\Debug\BuildLog.htm"
This log demystified the problem for me.
In my case, it had the following explicit error message:
c:\Documents and Settings\adam\My Documents\Visual Studio 2008\Projects\MyProject\MyProject\UnitTests.h(36): Error: Meta object features not supported for nested classes
The problem had been that INSIDE the class I defined here, I defined yet another internal (nested) class, that included the QT macro (so I could define signals and slots):
Q_OBJECT
Obviously QT wasn't happy that this class was nested/internal in another class. So I simply moved the class definition outside (IE made it non-internal).
No, it is not.
Did you look up the error code error PRJ0019.
I'm trying to use iphlpapi (GetAdapterInfo) and am having trouble compiling the code. I have iphlpapi.h from SDK 7 and have added the appropriate path to the include files in visual studio.
I get the following error...
c:\program files\microsoft sdks\windows\v7.0\include\ifdef.h(154) : error C2146: syntax error : missing ';' before identifier 'NET_IFTYPE'
The lines in ifdef where this occurs are shown below.
typedef NET_LUID IF_LUID, *PIF_LUID;
typedef ULONG NET_IFINDEX, *PNET_IFINDEX; // Interface Index (ifIndex)
typedef UINT16 NET_IFTYPE, *PNET_IFTYPE; // Interface Type (IANA ifType)
I finally figured out how to get this to work so I'm putting this here for others who might stumble upon it.
First, I'm using visual c++ version 6.0 with the 2003 sdk. I added the sdk as the first choice using TOOLS->OPTIONS->DIRECTORIES. Adding the include winsock2.h caused about 60 redefinition errors. I found several sources telling me that the winsock2 include had to precede the windows.h include. My windows.h include was generated for me by VC++ in the precompiled header stdafx.h so I moved the winsock2.h include there. I now can compile and run my program!
According to this page, it looks as though you might need to make sure winsock2.h is included first. I'm guessing that it defines some of those types.
Also, the MSDN page for NET_LUID says it requires Vista at a minimum. Make sure that's true.
