I am trying to make works libtorrent on VS2015 with boost 1.60. I built both and trying to build example "simple_client" from libtorrent but unfortunately it shows me:
unresolved external symbol if_nametoindex (broadcast_socket.obj)
Any ideas?
the if_nametoindex function is defined in iphlpapi.dll. See the documentation on msdn.

On compiling GOBJECT in Visual Studio, I came across below two
errors:
Error 5 error LNK1120: 1 unresolved externals C:\gtk_compilation\glib\glib-2.46.0\build\win32\vs12\Debug\Win32\bin\gobject-2-vs12.dll gobject
Error 4 error LNK2019: unresolved external symbol ___chkstk_ms referenced in function _ffi_call C:\gtk_compilation\glib\glib-2.46.0\build\win32\vs12\libffi.lib(ffi.o) gobject
I recompiled the libffi using the procedure described here but with
extra flags given to ./configure like below.
cflags="-fno-stack-check -fno-stack-protector -mno-stack-arg-probe"
which i hope will get rid of the ___chkstk_ms invocations.
After make and make install of libffi, I renamed the libffi.a to libffi.lib and libffi.dll.a to libffi.dll and copied them to appropriate directories.
Then I re-build the gobject project in visual studio and I got the same error
which I mentioned in the beginning. :(
Edit:
From this post, I guess the problem's root is that I am using two compilers. But i don't see a way to get around it. I tried to compile
the libffi using Visual Studio Projects available, but hours of efforts
were in vain.
I resolved this using the MSVC build of Libffi found in the Github project.
However, you need to change the line#606 from
sizet z = (*p_arg)->size;
to
unsigned long long z = (*p_arg)->size;
because the typedef is not (for some reason effective here).
I've been struggling to compile my Visual C++ 2010 project with dependency of Zlib. I've got source code that worked on Linux and Mac OS X. Here's, where I have linker errors:
error LNK2019: unresolved external symbol _inflate#8 referenced in function...
error LNK2019: unresolved external symbol _inflateInit2_#16 referenced in function...
error LNK2019: unresolved external symbol _deflate#8 referenced in function...
error LNK2019: unresolved external symbol _deflateInit2_#32 referenced in function...
I've been finding solution for few days now, trying compiling Zlib different ways, but it is clear that I've missed something. Very similar question has been answered here, but not clearly enough for amateur like me. I would need step-by-step guide how to get it to work.
Thank you in advance.
If you have static libraries after building the Zlib, point them in your project at this location.Project properties -> Linker -> Input -> Additional dependencies. Give the absolute path.
I built boost latest version (64 bit, msvc-10.0). When using the libraries with my project getting following linker error:
error LNK2001: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::system_category(void)" (?
Things checked:
1. Libraries are present in the path specified
2. Built 64-bit boost library
3. Using latest boost headers, etc..
Any suggestions?
I've experienced the same problem when using some header-only boost library. The problem is some libraries are themselves header-only, but they depend on boost.system which need be linked against your program.
I am trying to built a .cpp file using OpenNI in Visual Studio 2012. I am using the code of the SimpleViewer sample (it is included in the OpenNI). When I try to build the .cpp file I got the error LNK2019 which it seems a problem when the compiler has to link the OpenNI library. What could be wrong?
Errors (55 in total):

I followed all the steps described in the OpenNI website to compile a file in Visual Studio: I added all the VCC Directories and the Include and Lib environment variables. I also added OpenNI2.lib in the additional dependencies on the Linker section. I also copied the Redist files in the working directory (the directory where I have the .vcproj).
I ran into a similar issue. The sample projects wouldn't build because I was using OpenNI for x64 but the platform was set to Win32. Changing to x64 (in the properties dialog at the top) fixed it for me.
OpenNI 2.0 is not mature enough. Most of the libraries, open source codes, examples and wrappers still use OpenNI 1.5. The integration is not easy since OpenNI2 uses the Microsoft official drivers and OpenNI1.x uses the open source drivers. The 32bit version gives less problems than the 64bits but I ended up installing and working the OpenNI 1.5 and the Kinect non-official drivers.
The problem is related to the linking process. You may have wrong link path in the properties of your projects. There is solution, check this question
maybe it works in your case!
I've been attempting to install glew and freeglut to use with Visual Studio 2010. I followed this guide and have backtracked a few times to make sure I followed it correctly but I still get the following errors when I try and compile the example code at the end:
Error 1 error LNK2019: unresolved external symbol _imp_glutMainLoop#0 referenced in function _main c:\Users\Esteban\documents\visual studio 2010\Projects\Chapter 1 Project\Chapter 1 Project\main.obj Chapter 1 Project
Error 2 error LNK2019: unresolved external symbol _imp_glutDisplayFunc#4 referenced in function _InitWindow c:\Users\Esteban\documents\visual studio 2010\Projects\Chapter 1 Project\Chapter 1 Project\main.obj Chapter 1 Project
Error 3 error LNK2019: unresolved external symbol _imp_glutReshapeFunc#4 referenced in function _InitWindow c:\Users\Esteban\documents\visual studio 2010\Projects\Chapter 1 Project\Chapter 1 Project\main.obj Chapter 1 Project

and more just like those. I don't know if its a problem but originally I accidentally grabbed the 64bit version. I realized my mistake and overwrote the files with the 32bit versions, then cleaned and attempted the build again with the same result.
Are you sure that you have done "Step 6: Project Settings (Linker)" in linked guide correctly? It seems that the linker is unable to find symbols that are defined in those libraries (glew and glut32.lib). Also make sure that the Visual Studio knows where to find those libraries (Project->Properties->Configuration properties->VC++ Directories->Library Directories).
All the unresolved external symbols should be found in freeglut.lib. Are you sure that you are properly linking to this library?
Instead of trying to accomplish this in the you could just insert the following line of code in one of your header files:
#pragma comment(lib, "freeglut.lib")
I had this problem too. It turns out I was using the express version of visual studios, so I had to download microsoft sdk to get 64bit openGL libraries. Basically, I found this guide more helpful: http://www.cs.uregina.ca/Links/class-info/315/WWW/Lab1/GLUT/windows.html
