I'm having some problems with using CEF in my application which uses the MD/MDd runtime library linking.
I have downloaded the latest build of CEF3 from cefbuilds.com and followed the instructions How to link CEF against a different run-time library.
I have built the "libcef_dll_wrapper" project after changing "Runtime Library" to "/MDd" and "Platform Toolset" to "v110" and then I've linked the resulting "libcef_dll_wrapper.lib" binary to my project.
However, when I try to build my project I get the following errors:
12>html.lib(html_producer.obj) : error LNK2019: unresolved external symbol _cef_string_utf16_clear referenced in function "public: static void __cdecl CefBrowserSettingsTraits::clear(struct _cef_browser_settings_t *)" (?clear#CefBrowserSettingsTraits##SAXPAU_cef_browser_settings_t###Z)

Any ideas as to what I might be missing?
Are you also libcef.lib in the linker input?

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.
I've been trying to build using static qt for a while but i can't get rid of these errors .

I am using these libraries :
ws2_32.lib
imm32.lib
winmm.lib
qtharfbuzzng.lib
qtpcre.lib
Qt5PlatformSupport.lib
qwindows.lib
opengl32.lib
Can any of you explain me what i am doing wrong ? Thank you.
I've had the exact same issue. You're missing the freetype library qtfreetype.lib.
Add the following line to your .pro file
LIBS += -lqtfreetype
You need QtCore and QtGui at a minimum for this. QString is in QtCore and QGuiApplication is in QtGui. If your Qt usage is restricted to user interface activities, that might be enough. Otherwise, for each class that's failing to link, look in Qt Assistant. The "qmake" note at the top of the page says which library contains that class.
For instance, for Qstring, it has "qmake: QT += core". For Visual Studio on Windows, the actual filenames for the "core" library are Qt5Core.dll (release) Qt5Cored.dll (debug).
Added my case, hope this will helpful.
I'm lost one CPP file in the library project
Be careful when compilation (Lib & Project) has different option MT/MD options
OpenCV => 3.1.0
Operating System / Platform => Windows 10 / x64
Compiler => Visual Studio 2013

All libraries seem to be linked properly and I am not getting any error while writing the code.
It would be great if anyone could say what the error is. Thanks!
I am trying to build OSGEarth using CMAKE and Visual studio 2013
I first downloaded Open Scene Graph 3.2 and the prebuild dependencies (small package) from this page. I generated the visual studio 2013 project and build/installed Open Scene Graph without much problem
After that, I downloaded the source of osgearth 2.5 and generated the Visual Studio 2013 project, using the same dependencies as for Open Scene Graph (I don't want to use the optional dependencies for the first build) and when I try to build the osgEarth project, I got the following error at the linking step :

The only think I was able to find is that all the missing method seems to be deprecated ODBC method, like this one
For additional information, the project got a reference to odbc32.lib in its inherited values.
Okay, stupid question... the odbc's dependencies were in the inherited values... but the checkbox indicated to the build process to use these dependencies was not checked. Once it was done, everything is good... I think I need either a coffee or a very big smack on the head...
I'm trying to compile SOCI (http://soci.sourceforge.net/) which use OCI (Oracle Call Interface) under windows.
Details: Visual studio 2012, Oracle version 11.2.0; 64 bit
I found $(ORCALE_HOME)/OCI/LIB/MSVC libraries. But it won't like (I tried both oraocci11.lib and oci.lib.
The linkage error I get:

Any Ideas? I'm really stuck on that one.
Thanks, Guy
Well, I found eventually a oci.lib that I can link against ("Instant Client Package")
