This is not a new question but the solutions haven't worked for me. I want to read dicom files using C++. I have 32-bit Windows PC with VS 2013 community edition.
This post and other answers therein suggested using DCMTK. I installed DCMTK (using CMake followed by VS) and configured it for use with VS using guidelines and links provided in this post. Then I wrote a simple test program and tried to compile it:
#include "stdafx.h"
#include "dcmtk\dcmdata\dctk.h"
#include "dcmtk\config\osconfig.h"
#include "dcmtk\dcmimgle\dcmimage.h"
#include <iostream>
using namespace std;
int main()
{
DicomImage *image = new DicomImage("test.dcm");
if (image != NULL)
{
if (image->getStatus() == EIS_Normal)
{
if (image->isMonochrome())
{
image->setMinMaxWindow();
Uint8 *pixelData = (Uint8 *)(image->getOutputData(8 /* bits */));
if (pixelData != NULL)
{
/* do something useful with the pixel data */
}
}
}
else
cerr << "Error: cannot load DICOM image (" << DicomImage::getString(image->getStatus()) << ")" << endl;
}
delete image;
return 0;
}
Upon compilation, it gives the following error:
dcmdata.lib(dcuid.obj) : error LNK2019: unresolved external symbol _Netbios#4 referenced in function "unsigned char * __cdecl getMACAddress(unsigned char * const)" (?getMACAddress##YAPAEQAE#Z)
This error seems to be common but none of the following solutions work for me:
FAQ#27 and another post of DCMTK forum: It suggests using particular order of lib files to be included. My order of including files is as follows (I tried the reverse order as well but it didn't work):
All of this doesn't work. In fact, I'm not sure which lib files are supposed to be included? How to decide that?
I've also included "C:\Program Files\DCMTK\lib" under additional library directories and "C:\Program Files\DCMTK\include" under additional include directories in project properties.
Another similar question at stackoverflow has not been answered. Comments suggest to re-run CMake by disabling DCMTK_OVERWRITE_WIN32_COMPILER_FLAGS. I didn't do it because the DCMTK help page says don't disable this unless you really know what you're doing.
Can someone please guide?
The NetBios function resides in NETAPI32.LIB, so you can try moving NetAPI32.lib (which is in your list) to the top of that list.
Not sure which version of the DCMTK you use, but for the current development snapshot you need the following standard libraries (on Windows): "ws2_32 netapi32 wsock32". This information can be found in DCMTK's CMake files. By the way, you don't seem to use CMake for your project, right?
I think you misspelled dcmsign.lib as dcmsig.lib.
If changing that doesn't fix it, I would suggest the following order based on the support page that you linked to:
NetAPI32.lib
WSock32.lib
ofstd.lib
oflog.lib
dcmdata.lib
dcmsign.lib
dcmnet.lib
dcmsr.lib
dcmqrdb.lib
dcmtls.lib
dcmwlm.lib
dcmimgle.lib
dcmpstat.lib
dcmjpls.lib
dcmjpeg.lib
dcmimage.lib
ijg16.lib
ijg12.lib
ijg8.lib
I think that in this list, each library has to come after all the libraries that it depends on.
check your .lib and vs platform if the same ,such lib for x64, then your vs platform must be x64.
I had the same error. You can go to project properties-> linker -> input -> Additional Dependencies-> Edit -> add these two libraries-( netapi32.lib,wsock32.lib) before all other libraries . This solved the error for me .

I installed Aspose.Cells and tried to write a simple C++ file that includes Aspose.Cells.h. I soon realized that I had to install two other external libraries, boost and icu4c as without these libraries my compiler would throw errors saying some h or hpp files can not be found.
My problem is: even after I installed these libraries, I still couldn’t compile my code, as I received a new error saying “Fatal ERROR: comdef.h: No such file or directory.”
And the error persisted even after I installed the latest version for SDK for Win 10.
My simple file can run if I remove the line "#include Aspose.Cells.h" .
Can someone please enlighten me as to how to solve this error?
Also I noticed there is a folder called “Publish” under “include” folder for Aspose.Cells. This folder is besides boost and icu. Could this mean Publish is the third external library to be installed? But I couldn’t find any library called Public on the web. Pls see the screenshot below.
directory of include folder that comes with the installed Aspose.Cells package
Thanks a lot!
My code is as follows:
#include <iostream>
#include <Aspose.Cells.h>
using namespace std;
int main() {
cout << "hello!!!" << endl;
return 0;
}

Can someone please help me with my issue with Aspose.Cells library for C++?
I was writing my first C++ programme using Aspose.Cells library. Everything seemed smooth except that the following error was produced after I built the file:
Error before I launch is:
"Error exist in a required project.Continue launch?"
Error after running the code is:
"**fatal error: boost/config/compiler/gcc.hpp: No such file or directory**".**
If I commented out the line #<include Aspose.Cells.h>, the file can run with no errors.
I tried to solve the error by installing Boost library for C++ from zip file "boost_1_73_0", as I think Aspose depends on Boost to run. However, I couldn't link to Boost successfully as there doesn't seem to be a "include" folder and "lib" folder for me to add into project properties.
My questions are:
Will installing Boost solve my problem?
If yes, how can I install Boost library successful?
The following is my code in C++. Thanks a Lot in advance!
#include <iostream>
#include <Aspose.Cells.h>
using namespace std;
int main() {
cout << "!!!I am little red!!!" << endl;
return 0;
}

UPDATE: I have successfully installed and linked Boot library now but I have got three warning message upon building: "Ignoring #pragma warning [-wunknown-pragmas]" , are these warning messages serious?
I also ran into another fatal error: unicode/uloc.h:No such file or directory. How can I correctly link up to unilib-master/Unicode library?
Yes, installing Boost helps.
If Aspose only requires header-only libraries from Boost, then you don't have to do much. The "include" path you're looking for is just the folder where you extracted the zip. The actual library headers are under boost/ in that folder, which are then found by the compiler.
If you need the shared libraries, you will need to build them. Follow the steps here Getting Started On Windows
I have found two similar questions this and this .
But they both use opencv, and opencv indeed provide the corresponding lib. I don't use opencv, and my project is very simple, just hello world.I have changed project default configuration like this
except for these configurations, others all take defaults
I just want to test my project configuration，that works find for win32 debug and release. But not work for x64 debug and release, they all tell me LINK : fatal error LNK1104: cannot open file 'opencv_world341d.lib'
I indeed know my project does not use any opencv lib, but why they tell me I need to use opencv_world341d.lib
my code
#include<iostream>
using namespace std;
int main()
{
cout << "hello world" << endl;
}
Thanks for everyone who comments on the question. I have solved the problem, although this problem not relevant to OpenCV to much, but I think the solution to the problem may be helpful to others. When I build project, visual studio 2019 tell me cannot link opencv_world341d.lib, so I go to Project->Properties->Linker->Input->Additional Dependencies , and I found opencv_world341d.lib. So I need to remove it, but it's readonly. From this we know visual studio using settings file (Microsoft.cpp..users.props) to control global settings including Global search path. These files are located at $(USERPROFILE)\appdata\local\microsoft\msbuild\v4.0 directory. Then I reedit Microsoft.cpp.<Platform>.users.props, delete opencv_world341d.lib, reboot visual studio, problem solved.
I am trying to get a graphical representation of a chess-board with SFML 2.0. The problem is that I simply cannot load a texture, the command loadFromFile does not work and I don't know why. I already searched the web, also here in Stack Overflow but I did not find a solution.
What I did right now:
Setting all the dependencies for includes and libraries, .dll's and .libs
Changing text format from unicode to multibyte.
Copying the .dll's into the working folder (there was an error that visual studio couldnt find the dlls even though I linked them in the project)
Using the whole path for the image file
using the LoadFile-command with 2 arguments (even though the second one is optional I guess)
Changing runtime library from MDd to MD (trying to get it work in release mode)
Not linking all libraries, but only the ones with a ....-d.lib ending (as supposed in another Stack Overflow thread)
I use Windows 7, Visual Studio Version 15.3.3
This is my code:
#include <SFML/Graphics.hpp>
#include <time.h>
#include <iostream>
int main() {
sf::RenderWindow window(sf::VideoMode(437, 437), "MattseChess!");
sf::Texture t1;
if (!t1.loadFromFile("C:/Users/Mattse/source/repos/Chess/Chess/images/figures.png")) {
std::cout << "Error loading texture" << std::endl;
}
return 0;
}
What shall I try out next?
You should always open files with a relative path ("images/figures.png"). It's relative from the executable.
And check with an other PNG images to see if it does not come from the image that SFML cannot load for any reasons (and try gimp to reexport it with different options like interlacing for example)
I'm guessing (from the C:\Users\ part) you are on a Windows system.
While Windows should support slashes as path separator, the official path separator in Windows is a backslash. It needs to be escaped in C++, so your full path would be:
"C:\\Users\\Mattse\\source\\repos\\Chess\\Chess\\images\\figures.png"
Problem fixed, it was in fact the case that I forgot to delete one library in the linker->input settings. I only have the ones with a -d ending now, even the ones which have NO -d equivalent got deleted.
List of linked libraries:
sfml-audio-d.lib
sfml-graphics-d.lib
sfml-main-d.lib
sfml-network-d.lib
sfml-network-s-d.lib
sfml-system-d.lib
sfml-system-s-d.lib
sfml-window-d.lib
sfml-window-s-d.lib
This is the first question I have found myself not being able to get to the bottom of using my normal googling/stack overflowing/youtubing routine.
I am trying to compile a minimal Lua program inside of a C++ environment just to ensure my environment is ready to development. The Lua language will be later used for User Interface programming for my C++ game.
First some basic information on my environment:
Windows 7 64-bit
Visual studio 2010
Lua for Windows 5.1 (latest build I could download from google code)
Here is the code I am trying to compile:
// UserInt.cpp : Defines the entry point for the console application.
//
#pragma comment(lib,"lua5.1.dll")
#include "stdafx.h"
#ifndef __LUA_INC_H__
#define __LUA_INC_H__
extern "C"
{
#include "lua.h"
#include "lauxlib.h"
#include "lualib.h"
}
int _tmain(int argc, _TCHAR* argv[])
{
lua_State * ls = luaL_newstate();
return 0;
}
#endif // __LUA_INC_H__
Here is the Error I am getting:
1>UserInt.obj : error LNK2019: unresolved external symbol _luaL_newstate referenced in function _wmain
1>c:\users\deank\documents\visual studio 2010\Projects\UserInt\Debug\UserInt.exe : fatal error LNK1120: 1 unresolved externals
Things I have tried:
I have read about lua_open()(and several other functions) no longer being used so I tried the newstate function instead. I get the same error. This was more of a sanity check than anything. I am using 5.1 and not 5.2 so I do not think this really matters.
I have also read this thread Cannot link a minimal Lua program but it does not seem to help me because I am not running the same environment as that OP. I am on a simple windows 7 and visual studio environment.
The top pragma comment line was something I saw in yet another thread. I get the same error with or without it.
I have gone into my visual studio C++ directories area and added the lua include to the includes and the lua lib to the libraries.
So it seems like my program is seeing the .h and seeing the symbol. But for some reason it is not getting the .cpp implementation for the functions. This is why I was hoping including that .dll directly would help fix the problem, but it hasn't.
So, I feel like I have exhausted all of my options solving this on my own. I hope someone is able to help me move forward here. Lua looks like an awesome language to script in and I would like to get my environment squared away for development.
I hope it is just some silly error on my part. I believe I have provided as much information as I can. If you need more specifics I will update with info if I can provide it.
Edit1
Tried the solution in this Can't build lua a project with lua in VS2010, library issue suspected
That did not work either.
You'll need to have the library (.LIB) file and add that to VS. Use Project > Properties and go to Linker > Input and add the full .lib filename to the "Additional Dependencies" line. Note that the .LIB is different from the .DLL.
Personally, I prefer adding the source code to my project, over referencing the dynamic link library. The following procedure will let you do as such.
Download the source code ( http://www.lua.org/ftp/ ), uncompress it.
In Visual Studio, choose File > New > Project and choose Visual C++, Win32, "Win32 Console Application".
In your project in Visual Studio, add all the source code, except luac.c. Also delete the main() function out of the file that VS created for you. This is usually given the name of the project you specified with the .cpp file extension. You could just remove this file all-together from the project.
Build and Run.
