Unresolved symbols when linking a program using libcurl
I’ve been using static version of libcurl, and to link my program against it properly, I had to add definition: CURL_STATICLIB to build configuration of my project.

Unresolved externals in C++ when using vectors and find
I found another forum post, where somebody seems to have reported the same exact problem that you are having. Please check to see if you have _DEBUG defined either in your project settings (under C/C++ — Preprocessor) or somewhere in your code (or include files). It looks as if std::vector thinks you are building a … Read more
Unresolved external symbol LNK2019
The problem is you are not linking against the Ws2_32.lib library. To fix this you can add that to your additional dependencies tab of linker/Input settings for your project. Alternatively (as pointed out by SChepurin in the comments) you can add #pragma comment(lib, “Ws2_32.lib”) to a source file of your project.
unresolved external symbol __imp__fprintf and __imp____iob_func, SDL2
I have finally figured out why this is happening ! In visual studio 2015, stdin, stderr, stdout are defined as follow : #define stdin (__acrt_iob_func(0)) #define stdout (__acrt_iob_func(1)) #define stderr (__acrt_iob_func(2)) But previously, they were defined as: #define stdin (&__iob_func()[0]) #define stdout (&__iob_func()[1]) #define stderr (&__iob_func()[2]) So now __iob_func is not defined anymore which leads … Read more
Unresolved external symbol in object files
This error often means that some function has a declaration, but not a definition. Example: // A.hpp class A { public: void myFunc(); // Function declaration }; // A.cpp // Function definition void A::myFunc() { // do stuff } In your case, the definition cannot be found. The issue could be that you are including … Read more
What is an undefined reference/unresolved external symbol error and how do I fix it in Fortran?
A link-time error like these messages can be for many of the same reasons as for more general uses of the linker, rather than just having compiled a Fortran program. Some of these are covered in the linked question about C++ linking and in another answer here: failing to specify the library, or providing them … Read more
What is an undefined reference/unresolved external symbol error and how do I fix it?
Compiling a C++ program takes place in several steps, as specified by 2.2 (credits to Keith Thompson for the reference): The precedence among the syntax rules of translation is specified by the following phases [see footnote]. Physical source file characters are mapped, in an implementation-defined manner, to the basic source character set (introducing new-line characters … Read more
