Error Lnk2019 Unresolved External Symbol Visual Studio 2010
compile my program, I'm getting unresolved externals for everything that uses SFML. I've had problems with this on multiple machines, and also with some other libraries in some case. I'm using the following command to generate my Visual Studio Project (inside a VisualStudioProject folder): Z:/Coding/cmake/cmake-3.1.1-win32-x86/bin/cmake.exe -G "Visual Studio 12" .. And this is my CMakeLists.txt (it's actually generated from a python script I wrote, but I doubt that's important). I can confirm that all the libraries are being found correctly. cmake_minimum_required (VERSION 2.6) set( CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR}/bin) set( CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/lib ) set( CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/lib ) project(Game) include_directories( Z:/Coding/Libraries/SFML/SFML-2.2/include Z:/Coding/Game/src/win32 Z:/Coding/Game/src ) find_library( SFML-GRAPHICS NAMES sfml-graphics PATHS Z:/Coding/Libraries/SFML/SFML-2.2/lib NO_DEFAULT_PATH ) find_library( SFML-WINDOW NAMES sfml-window PATHS Z:/Coding/Libraries/SFML/SFML-2.2/lib NO_DEFAULT_PATH ) find_library( SFML-SYSTEM NAMES sfml-system PATHS Z:/Coding/Libraries/SFML/SFML-2.2/lib NO_DEFAULT_PATH ) add_executable( win32 "Z:/Coding/Game/apps/win32.cpp" ) target_link_libraries( win32 ${SFML-GRAPHICS} ${SFML-WINDOW} ${SFML-SYSTEM} ) This is my simple SFML test program: #include

However the library download does not supply you with precompiled headers and instead requires Cmake. This wouldn't be a huge problem, except that their tutorial on the http://stackoverflow.com/questions/12701926/compiling-a-library-with-cmake subject is extremely incomplete. I've never used Cmake before, and searching shed no light on the problem. I've ran Cmake with the Visual Studio 10 compiler, which generated a bunch of Visual Studio projects. I compiled those projects into 2 libraries, and included the library directories in the project's properties. I also put all of PolyVox's header files in directories Visual Studio is aware of. When attempting to compile my project I get linker errors such as: 1>Gamestate.obj : error LNK2019: unresolved external symbol "public: __thiscall PolyVox::Region::Region(class PolyVox::Vector<3,int> const &,class PolyVox::Vector<3,int> const &)" (??0Region@PolyVox@@QAE@ABV?$Vector@$02H@1@0@Z) referenced in function "public: __thiscall Gamestate::Gamestate(void)" (??0Gamestate@@QAE@XZ) Could someone please explain to me how to properly include PolyVox into my code using Cmake? c++ visual-studio linker cmake voxel share|improve this question asked Oct 3 '12 at 4:31 Zeke 649 add a comment| 1 Answer 1 active oldest votes up vote 5 down vote accepted You forgot to add polyvox library in your game project. It's in the Linker menu and called "Additional dependencies", IIRC. share|improve this answer answered Oct

anyone help me, please? I am using Windows 8 -64 bit system and try to program Nao by C++ language. Basically, I already install all the software that are needed to use for programming. Including Qibuild (1.14.3) , Cmake (3.1.1) , Visual Studio 2010 , naoqi-sdk-2.1.2.17-win32-vs2010, pynaoqi-python2.7-2.1.2.17-2.win32, python 2.7.9. After that I can run Qibuild by cmd.
