Add User32.dll to your link stage.
Note: Name is misleading inasmuch that the 64 and 32 bit versions are both called user32.
use #include< windows.h> instead of #include "Windows.h"

As the title suggests, I have an linker error relating to my inline file. It is complaining that my dungeon_layout header that includes my dungeon_room header(which includes the inl file) defines something twice. All my headers have guards, I only include .hpp files, and yet it still gets angry when I try and overload the assignment operator. The code which it complains is such:
Where I need assignment 1:
dungeon_room dungeon_layout::getCurrentRoom()
{
...
dungeon_room temp;
for (row = levelLayout.begin(); row != levelLayout.end(); row++)
{
for (col = row->begin(); col != row->end(); col++)
{
if (col->active)
{
...
temp = *col;
...
}
}
...
}
return temp;
}
Where I need assignment 2:
dungeon_room::dungeon_room()
{
...
roomMap = tim::tileMap(20, 20, 50);
...
}
Assignment Operator 1:
tileMap tim::tileMap::operator=(const tileMap& other)
{
// nothing...
}
Assignment Operator 2:
void dungeon_room::operator=(const dungeon_room& other)
{
// nothing...
}
Header for the Tile Manager (inl file definitions for functions)
#ifndef DUNGEON_ROOM_HPP
#define DUNGEON_ROOM_HPP
...
#include "gridManager\tileManager.hpp"
...
#endif
Header for the level layout
#ifndef DUNGEON_LAYOUT_HPP
#define DUNGEON_LAYOUT_HPP
...
#include "dungeon_room.hpp"
...
#endif

I believe that this should be the relevant code. I've been stuck, and debugging for a while now, and it's been annoying. Please help, thanks!
The reason you are getting these errors is because the function is being compiled for each .cpp file it has been compiled in, which is then being exported multiple times, once for each .cpp file that includes your inline file.
The .inl file that contains the definition is pasted into each of the .cpp files that includes it. Meaning, when the program is linked together, there is a definition of the function, that was supposed to only be defined once, in several files. This breaks the One Definition Rule and is the reason the linker is giving you that error.
To fix it, you have three options. First, you can mark the functions as inline, which does not necessarily make the compiler inline the function, but allows the function to be defined multiple times. Second, you can move the definition of the function inside the definition of the class, which implicitly marks the functions as inline. Or you can define the function in a .cpp file.
With you code, if you still want to have the functions declared in an .inl file you can put inline in front of the definitions of the function in the error messages. In this case those functions are
tim::tileMap::addSprite
tim::tileMap::modifyTile
tim::tileMap::addCollisionValue
tim::tileMap::drawTiles //All 4 overloads
tim::tileMap::operator=
tim::tileMap::tileMap //Both constructor overloads
i am getting the following error
error LNK2019: unresolved external symbol "public: class

My function defination is as follows:
CString CFILicenseSettings::GetCodeStartup1()
{
CString a = "why";
return a;
}
the declaration of the function is as follows:-
CString GetCodeStartup1();
When i searched the web for the above error i found that this error is because my class is derived from CString class,but this is not the case.....
I get this error when i call the function GetCodeStartup1();
if i comment the calling of function GetCodeStartup1(); my program compile successfully
How can i remove the error?
Thanks in advance
I have created .dll file in Visual C++.
It includes a function which takes two arguments and send data through serial port. Next i wanted to include this .dll in my application and call these functions. But i am unable to call these functions. Kindly Help.
Here is header file for my .dll
namespace positioncontrol
{
using namespace std;
using namespace System;
using namespace System::IO::Ports;
public ref class control
{
static int rotate(char a, String^ b);
};
}
And here is .cpp for my .dll
#include "goniometer.h"
namespace positioncontrol
{
void control::rotate(char a, String^ b)
{ SerialPort^ serialPort = gcnew SerialPort(L"COM5",9600,Parity::None,1,StopBits::One);
int inp_rotation;
array<unsigned char>^ inp_c = gcnew array<unsigned char>(2);
String^ inp_string;
inp_c[0] = a;
inp_string= b;
inp_rotation=Int32::Parse(inp_string);
inp_c[1] = (unsigned char)inp_rotation;
serialPort->Write(inp_c,0,2);
}
}
I am using this .dll in a desktop application. I have include the header file
#ifndef goniometer_h
#define goniometer_h
#include "goniometer.h"
#endif
Added the path for include directories and added .dll as a reference.
Now i am using the function defined in .dll for a click event
private: System::Void button9_Click(System::Object^ sender, System::EventArgs^ e) {
char dir;
dir = 0x42;
String^ inp_string;
inp_string=enter_degree->Text;
positioncontrol::control::rotate(dir,inp_string);
}
Now when i build my desktop application i am getting following error
1>C:\Users\DELL\Desktop\Final\Motor_Dual_API\Debug\goniometer.h(10): error C2011: 'positioncontrol::control' : 'class' type redefinition

Kindly help me in figuring out error.
Thanks and Regards
In C++, the namespace separator is :: rather than .. Check your using statement.
Your code does not define serialPort. Add the definition to the global namespace, to the namespace positionControl or as an auto variable in your function
From the semantic point of view, serialPort is a pointer. So must also create an instance of the object, where serialPort points to.

P.S I also use functions from cvBlobslib and code from LIBSVM but it should not be the problem
If you change to use /MT and /MTd, then all your dependent libraries also need to have been compiled with these settings.
If this is not the case, then these dependencies require linking to the dynamic CRT and your project is trying to link to the static CRT, causing the "already defined" errors you're seeing.
I am quite new at working with libraries, and I have some problems.
I have installed PCL and all dependencies on my computer (Windows 7, 32 bit) and I can build and use simple examples like that "Simple Cloud Visualization" example. But if I want to use more complete sample, Visual Studio 2010 reports linking errors.
If I understand correctly, I did not 'include' all necessary "Additional Dependencies" in "Linker/Input". I tried to include all .lib files from lib directory, but the error report is still the same.
Does anyone know, which .lib should be added as "Additional Dependencies" to make more complete sample work? Or is problem somewhere else?

Probably you installed the wrong PCL version (64 bit / 32 bit). Check your VS version and install PCL accordingly. Note that even if you are using a 64 bit system, your compiler may be working in 32 bit.
