Error Lnk2019 Unresolved External Symbol Winmain@16 Referenced In Function ___tmaincrtstartup
error LNK2019, snprintf(), c up vote 3 down vote favorite I'm trying to run a unix compiler-project written in c with MS Visual-Studio 2013 and I can't get rid of the following error: error LNK2019: unresolved external symbol "_snprintf" referenced in function "PUBLIC void SyntaxError( int Expected, TOKEN CurrentToken )" If I get it right it is a problem where VisualStudio can't find the body/declaration from error lnk2019 unresolved external symbol public __thiscall referenced in function _main the snprintf() function, which should be defined in stdio.h. The project works fine with cygwin. I had to add _CRT_SECURE_NO_WARNINGS to preprocessor settings to get this far, but i don't think that has a influence. Here is the named function: #include

I'm pretty sure this is not related to something in the code so I did not post a sample, but if you require one, I'll post it. c++ visual-c++ codeblocks share|improve this question asked Jan 26 '14 at 21:21 Mark Hedberg 361210 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted Linker errors are generated due to how c++ and many other similar languages compile and link code. The compiler generates object files (*.obj) and only requires function declarations in order to compile code that calls these functions- that's why forward declarations and header files work. After compilation, at link time, the linker looks for the definitions of these functions in compiled files (usually in object files (*.obj) or libraries (*.lib). A linker error saying "Unresolved external symbol" means a declaration without matching definition has been used. Most often this is because of a spelling error in the declaration or definition, or because the file containing the definition was never linked. Long story short, you are missing a reference to a library. That might be libcmt.lib for release and libcmtd.lib for debug. share|improve this answer answered Jan 26 '14 at 21:39 Peter 3,1261033 Ah right, before I was getting this error, I was getting a different one that "wcrt.lib" couldn't be opened/found but I specified the library's directory in the linker though
