    [RESOLVED] Error while statically linking Libsodium

    It appears that I'm linking libsodium correctly, but I'm getting linker errors for _sodium_init, I'm using Visual Studio 2015, and the libsodium.lib (prebuilt) for msvc 140 (for vs2015). The project is c++.

    This is how my setting look for linker: http://prntscr.com/ixv042

    For additional includes, my settings look like this: http://prntscr.com/ixv0mg

    The folder that the project resides in looks like this: http://prntscr.com/ixv0vw

    I'm including sodium.h as so: http://prntscr.com/ixv1go

    and of course, in main() I'm doing

    I'm not sure why I would be getting linker errors, does anyone spot anything wrong with the code?

    What linker errors are you getting?

    Have you followed the instructions re defining the required macro?

    Note for Visual Studio

    Projects willing to statically link Sodium must define a macro named SODIUM_STATIC. This will prevent symbol definitions from being referenced with __dllexport.
    For static linking, Visual Studio users should define SODIUM_STATIC=1 and SODIUM_EXPORT=. This is not required on other platforms.

    Yes, I followed the instructions, but I also figured out what the issue was.

    It was actually quite a foolish error on my part, I tried to link the x64 static library when the project was x86.

    Thank you for your effort 2kaud!
