I have no idea why I'm gettin gthese terrors because I'm 99% sure I've setup my directories correctly.
For example one of the functions it can't find is TextureFactory::CreateTextureFromFile yet I have the directory in which that function is declared and defined already added to the include/source directory in the Visual C++ settings.
Top of the file looks like this:
#include "nvafx.h"
//#include "NV_D3DCommon\NV_D3DCommonDX9.h" // include library sub-headers
// and add .lib to linker inputs
//#include "NV_D3DMesh\NV_D3DMesh.h"
//#include "shared\NV_Common.h"
//#include "shared\NV_Error.h"
#include "FogTombScene.h"
#include "ThicknessRenderProperties.h"
#include "ThicknessRenderProperties8BPC.h"
#include "../camera.h"
// When the following two lines are added I get more LNK2005 (understandable)
// but I also still get the same LNK2019 errors as above
#include "texturefactory.h"
#include "texturefactory.cpp"
More to the point if I say #include "TextureFactory.h" and #include "texturefactory.cpp" at the top of the file in which I'm getting these errors then there can be no room for ambiguity, the functions are defined and basically copy+pasted into the same source file generating the linker error, yet I still get the linker error.
Am I overlooking something?
That happend because:
1 The source of .lib is missing like said tomzx or Daniel,
or
2 The .lib it was compiled in another version of Visual C
Try to create your file like a .c (NOT a .cpp) in notepad, then you add to your project the file .c (project...add to project...file)
Sorry I'm Mexican, I don't speak english.
Saludos.
You have added the files in the include/source folder, but what about the libraries? Looks more like a library problem to me (missing .lib).
Maybe you also need to list your dependencies in Linker - Input.
LNK2005 generally means that additionnal libraries aren't correctly linked.
You probably forgot to link to one of the SDKs lib files. You can set this in your project properties under Linker->Input->Additional Dependencies or use a #pragma comment.

I am trying to do Catch2 Unit Testing in Visual Studio. I have created a small test project to practice. When I try to compile this test project, I get a linker error. I am now trying to diagnose this linker error, but the Catch2.hpp header file contains thousands of lines of code. My hope is that someone who is more familiar with Catch2 or unit testing in general can diagnose what the issue is.
I will describe the process by which I created this project. I created a new project in a new solution. I have 4 files, all in the same directory, listed below.
The class I want to test:
//a.h
#pragma once
class A {
friend int A_Tester_Func1(A a);
public:
A(int num) : my_num_(num) {
}
private:
int my_num_;
};
The test:
//atester.cpp
#pragma once
#include "catch.hpp"
#include "a.h"
int A_Tester_Func1(A a) {
return a.my_num_;
}
TEST_CASE("a contains a positive integer", "[a]") {
//...
A a(3);
REQUIRE(A_Tester_Func1(a) == 3);
}
The main function that runs the tests:
//tester.cpp
#define CATCH_CONFIG_MAIN
#include "catch.hpp" // this should create the main function
The Catch2 Testing Framework:
// catch.hpp
/*
* Catch v2.13.2
* Generated: 2020-10-07 11:32:53.302017
*/
//~17-18k lines of code that from Catch2
#endif // TWOBLUECUBES_SINGLE_INCLUDE_CATCH_HPP_INCLUDED
When I try to compile this code in Visual Studio using the Local Windows Debugger button, I get a bunch of Unresolved External Symbol linker errors. I believe I read somewhere that Catch2 is "partially compiled." That may have something to do with it, but I don't know. Following this guide (StackOverflow: Best practices for Unit testing with Catch2 in Visual Studio) has worked for me, but I'm trying to understand why the small example above is not successfully linking.
I have included the linker errors below for completeness, although I feel that they will probably not be necessary for the question.

What is causing these errors? How do I fix these errors while keeping catch.hpp in the same project as my source files?
In a .cpp file, add this to make the project a Catch2 test runner:
#define CATCH_CONFIG_RUNNER
#include "catch.hpp"
Read more at Supplying main() yourself
I ran into the same problem.
You need to keep #define CATCH_CONFIG_MAIN in the first line of the file, especially before other #include.
atester.cpp must not have the #pragma once directive. It's for header files, and while it may not be your source of trouble, it simply doesn't belong. Since you're not providing enough detail (namely: where's the minimized project file?), I have to be conservative here.
It seems that tester.cpp is not part of the project that you're building. Just because it's a file that exists on disk doesn't mean it's automatically picked up. You have to manually add it to the MSVC project. That's all there's to it. I use Catch2 with MSVS all the time and that's all it takes to make it work.

What is an undefined reference/unresolved external symbol error and how do I fix it?

Closed 3 years ago.
I am having trouble installing the Stanford C++ Libraries, in particular, the Graph related libraries that I need to use for a project. I am using the Visual Studio IDE, Eclipse IDE, so instructions tailored to either would be appreciated.
I have done the following already:
-> Downloaded and unzipped the library at https://stanford.edu/~stepp/cppdoc/
-> selected the 'collections' folder in StanfordCPPLib as #include directory for Eclipse/Visual Studio
-> things seem to work until this point, and #include works. But During compile time, a ton of other 'unresolved inclusions' occur.
Please can someone who has actually installed the library/willing to do so, help me to do the same. I have spent quite a bit of time trying to solve this myself, and this is a major bottleneck.
Specs: Windows 10 Home
MY CODE:
#include "pch.h"
#include <iostream>
#include <collections/basicgraph.h>
using namespace std;
int main() {
BasicGraph g;
g.addVertex("1");
g.addVertex("2");
g.addEdge("1", "2");
cout<< g.getVertex("1")->name <<endl;
//boost::optional<int>;
return 0;
}

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
Based on the error, it seems to be missing the library/implementations that it needs to link with to produce the executable. The library in the link that you provided, it's distributed as raw source. What you would have to do is to either incorporate that whole library into your project so that you can include and build it together with your own codes. Or you can build it as a separate project that would create a static library, then you can include its headers like you're currently doing and then link your program with the library that it produced.
Something like this:
MyProject\
main.cpp
stanfordlib\
collections\
graph.h
graph.cpp
....
then in your code include the library like this,
#include "stanfordlib/collections/graph.h"
This will allow your project to compile the lib and link it with your code.

I can't seem to find any information on compiling with OpenVDB in Visual Studio that covers this kind of error, and am pretty stumped as to what I could be forgetting.
It turned out to be a combination of a couple problems:
My OpenVDB binaries were compiled with OPENVDB_3_ABI_COMPATIBLE defined, and so were using the boost version of shared_ptr instead of the std version, but I hadn't defined OPENVDB_3_ABI_COMPATIBLE when trying to build my project, so it was trying to build using the std version; hence, undefined externals.
I hadn't defined OPENEXR_DLL and HALF_EXPORTS, which is evidently required when building with those libraries, unbeknownst to me.
I was compiling with the /MT option instead of the /MDd option used by half.lib
In the end, all I needed to do was define OPENEXR_DLL, HALF_EXPORTS, and OPENVDB_3_ABI_COMPATIBLE, and switch the build option to /MDd.
Try to use Vcpkg.
It supports visual studio 2015,2017

It's easy to use like yum in Linux.
I have two libraries A and B. Library B is my own library and I need "windows.h" in it. Also for some functions I need to use a third-party library A. A uses google logging library and here is the problem :
The first error was this :
Severity Code Description Project File Line Error C1189 #error: ERROR macro is defined. Define GLOG_NO_ABBREVIATED_SEVERITIES before including logging.h
I defined GLOG_NO_ABBREVIATED_SEVERITIES before "A.h", but after that strange linking errors appeared. I have tested all solutions suggested here but none of them works.
Is there any other ways to use glog in a project that uses "windows.h"?
EDIT :
The linker errors are :

I have recompiled A after adding GLOG_NO_ABBREVIATED_SEVERITIES, but nothing changed. But the problem solved by reordering the inclusion of "A.h" and "windows.h". When I include "A.h" before "windows.h" no error appears!!! I can not understand what was the real cause of linker errors! – payman
I'm developing a small Application using a QWidget and statically linking Qt 5.6. I'm using VS12 at moment.
#include <QMainWindow>
#include <QApplication>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QMainWindow w;
w.show();
return a.exec();
}
It compiles fine but I'm getting linker errors.

I have included the following libs:
winmm.lib
imm32.lib
Ws2_32.lib
opengl32.lib
Qt5Guid.lib
Qt5Widgetsd.lib
qtpcred.lib
qtharfbuzzngd.lib
Qt5PlatformSupportd.lib
qwindowsd.lib
libEGLd.lib
libGLESv2d.lib
qtfreetyped.lib
Qt5Cored.lib
And the funny thing is that if use QtCreator it compiles,links and runs just fine.
What I saw is that QtCreator adds the following compile flags:
-DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DQT_OPENGL_ES_2 -DQT_OPENGL_ES_2_ANGLE -DQT_OPENGL_ES_2_ANGLE_STATIC -DGL_APICALL= -DEGLAPI=
I tried them in my project but it does not change anything.
What am I missing? What do I need to make the program link?
I found it. This is the list of libs you need to make it work:
winmm.lib
imm32.lib
Ws2_32.lib
Qt5Guid.lib
Qt5Widgetsd.lib
qtpcred.lib
qtharfbuzzngd.lib
Qt5PlatformSupportd.lib
qwindowsd.lib
libEGLd.lib
libGLESv2d.lib
qtfreetyped.lib
Qt5Cored.lib
+ preprocessord.lib
+ translatord.lib
+ d3d9.lib
+ dxguid.lib
opengl32.lib is not needed.
I still have no idea why QtCreator knows what libs are needed and why VS2013 does not.
Thanks for your help.
As far as I can tell the linker is complaining about this line of code. Looking at what that file is including seems to suggest dependence on libANGLE.
After a lot of Googling I found that CreateTLS() seems to be defined in libANGLE common, which can be found here.
I'm not sure in which particular Lib or DLL those definitions end up but looking into the build scripts would definitely reveal it (sorry, I don't have time to do that atm). But the symbols in the original question are definitely in one of the Libs provided by libANGLE.
this page suggests that all you need to do is add libEGLd.lib and libGLESv2.lib to your linker line, which is already the case, but you should check that you also have the DLLs too. Note point 3, quoted from the linked page, below:
Copy libEGL.dll and libGLESv2.dll from the build output directory (see Building ANGLE) into your application folder.
If you add the DLLs to your solution you can automate copying them to the destination directory..
