问题 This question already has an answer here: What is an undefined reference/unresolved external symbol error and how do I fix it? 32 answers I've downloaded this C++ code from the SBIG website in order to control (take pictures and save them) the camera (model ST-401ME) which I purchased from them. I have a Matlab program which needs to call this so I'm trying to compile (with Visual Studio) this code with its headers and libraries into an executable. However, when I try I get the above

So, the infamous error is back. The project is complaining that it can't find the main() method (that's what the error means, right). However I do have a main, and my project is a Console project, as it should be. It worked before, so I know it's not that. Also, the project has too many classes and files for me to post them all, so I will post any classes you need by request. It's a C++, OpenGL and SDL game on Visual Studio 2010. It's not a problem of any of the libraries, as it was working fine before it suddenly and inexplicably showed this linker error. EDIT: The main() method: int main(int

I have the following error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup, There are a lot of threads relating to this error but none of those solutions worked for me. And, none explained why this error is here. I tried: wWinMainCRTStartup as entry point in the linker properties http://social.msdn.microsoft.com/Forums/en/vclanguage/thread/14e85604-6929-4707-a22e-8cdf596926a6 set the linker to "Windows" (same thread as above) Right click on solution name->Add->Existing Item->file with main (same thread as above) include error LNK2019: unresolved external

I am quite new to C++ so I downloaded a sample C++ program. The sample program seems to hit the following error when it is compiling :- Error 22 error LNK2019: unresolved external symbol _acsEnumServerNames@12 referenced in function "protected: virtual int __thiscall COpenTsrv::OnInitDialog(void)" (?OnInitDialog@COpenTsrv@@MAEHXZ) Opentsrv.obj I traced it to the referred function but I do not know anything wrong with it ? BOOL COpenTsrv::OnInitDialog() { CDialog::OnInitDialog(); CenterWindow(); acsEnumServerNames(ST_CSTA, AddToList, (unsigned long) (CComboBox*)&m_TserverListControl);

Linking error LNK2019 in MSVC, unresolved symbols with __imp__ prefix, but should be from static lib

你说的曾经没有我的故事 提交于 2019-11-27 08:36:23
I'm running into linking problems in MSVC for a project that I wrote for g++. Here's the problem: I build libssh as a static library as part of my application, adding the target in cmake with add_library(ssh_static STATIC $libssh_SRCS) Libssh is in C, so I have 'extern "C" {...}' wrapping the includes in my c++ sources. I then link the ssh_static target to my executable, sshconnectiontest, with target_link_libraries(sshconnectiontest ... ssh_static ...) This all works fine in linux with gcc, but now in MSVC I get error LNK2019: unresolved external symbol __imp__[function names here] referenced

问题 I'm trying to compile and run a C code that is using libsndfile library for sound files processing.

first time posting a question here to stackoverflow. Sorry if I butcher the formatting! I am attempting to follow a basic tutorial on openCV, namely this one: http://aishack.in/tutorials/tracking-colored-objects-in-opencv/ I have looked at various tutorial online on how to install openCV, including: Setup OpenCV-2.3 for Visual Studio 2010 and opencv.willowgarage.com/wiki/VisualC%2B%2B without much luck. The current version I have running right now is OpenCV 2.3.0. I am currently running on Windows 7 with Microsoft Visual C++ Express 2010. Whenever I try to build and run my code, I get the

不打扰是莪最后的温柔 提交于 2019-11-27 02:57:06
I get this error, but I don't know how to fix it. I'm using Visual Studio 2013. I made the solution name MyProjectTest This is the structure of my test solution: - function.h #ifndef MY_FUNCTION_H #define MY_FUNCTION_H int multiple(int x, int y); #endif -function.cpp #include "function.h" int multiple(int x, int y){ return x*y; } - main.cpp #include <iostream> #include <cstdlib> #include "function.h" using namespace std; int main(){ int a, b; cin >> a >> b; cout << multiple(a, b) << endl; system("pause"); return 0; } I'm a beginner; this is a simple program and it runs without error.
