unresolved-external

问题 This is in continuation for the thread "Unresolved external symbol error occurring only in 64-bit mode and not in 32-bit build" . I have a VC++ code (built using VS2008), which makes use of some static libraries (*.lib files linked statically during compile time). For ease of understanding let's refer my EXE code as "AAA.EXE" & refer the lib files as "A.lib", b.lib and LOGGER.lib (the library which is causing the below error) Both the AAA.EXE code and static libraries code (LOgger.lib) are

问题 I've facing this problem when trying to use boost::thread: unresolved external symbols: public: __thiscall boost::thread::~thread(void) public: __thiscall boost::thread::thread(void) Does anyone have any idea? 回答1: You haven't told your linker to link with the boost threads library. Without info on compiler and platform, nobody can help you further. 来源： https://stackoverflow.com/questions/3164668/boostthread-member-function

问题 I've got a VC++ project, and I'm attempting to use the extension of the gumbo-query library, found here. This library wraps/extends Google's gumbo-parser found here. The following is the exact steps I've taken - I'm not very familiar with importing libraries, so I've done what I do to use the Boost libraries: In Visual Studio (VS Community 2013), under the project settings -> Configuration Properties -> C/C++ -> General I have put the path to a folder that contains all of the source files

问题 I want to test Flandmarks for face detection http://cmp.felk.cvut.cz/~uricamic/flandmark/ But I cant get it to work. I've been working on this for probably 10 hours. I asked for help on opencv.org (http://answers.opencv.org/question/16956/eye-detection-is-jumping/ , the question were first about something else, see comments if you want to read what was said about this problem) And got some help but the problem is still there. Computer: 64bit, windows 7, Visual studio 2010. What I've tried:

问题 I am trying to implement the libraries from the company Appodeal (an Ad mediation company) to my App in Android Studio, so I can run their advertisements and monetize my App. I followed their instructions: First, put the necessary libraries in the libs folder Second, add the necessary dependencies in the gradle file: apply plugin: 'com.android.application' android { compileSdkVersion 27 buildToolsVersion '27.0.3' defaultConfig { applicationId 'com.languagematerial.lmmovies' minSdkVersion 23

问题 Let's say I have this class: in Vector4.h : #pragma once template<typename T> class Vector4 { public: T X; T Y; T Z; T W; Vector4(); Vector4(T X, T Y, T Z, T W); ~Vector4(); friend Vector4<T> operator*(const Vector4<T>& l, const Vector4<T>& r); }; #include "Vector4.inl" and in Vector4.inl : template<typename T> Vector4<T>::Vector4() { X = 0; Y = 0; Z = 0; W = 0; } template<typename T> Vector4<T>::Vector4(T X, T Y, T Z, T W) { this->X = X; this->Y = Y; this->Z = Z; this->W = W; } template

问题 Here is a preface - I have a C++ + Qt application, it consists of several projects and we are using MSVC 2012 to build it. Now, I'm implementing build scripts to start deploying build server. So, I started creating Qt .pro files for each and every project we have. Now the problem - we use Crypto++ library(http://www.cryptopp.com/) which we build from source code and the output is static lib, and we have DLL which depends on cryptlib.lib. I wrote .pro file for Cryptlib and I'm able to build it

问题 I'm currently trying to decide between DirectX and OpenGL by programming a little DirectX 10 and OpenGL 3.3. I already have the setup for DirectX finished, it was fairly easy to link and compile. OpenGl is... harder. The OpenGL Superbible has a beginning example called Triangle.cpp in which we link two libraries freeglut_static.lib and GLTools.lib . This isn't a problem; I have also gone to the Project Directories and included the Include/ and lib/ path of all necessary OpenGL extensions

问题 How to fix a Visual Studio 2012 error LNK2019: unresolved external symbol "__declspec(dllimport) public: class std::basic_string? I've been compiling a solution containing one exe and several static lib projects on which the exe depends fine with Visual Studio 2008.
