    Visual Studio 2010 x64 compilation

    Hi, I'm trying to compile a project of mine into x64. I'm on Windows 7 64, but apparently I needed to install the Windows SDK to be able to compile for x64 - I made sure x64 support was enabled during the installation.

    Either way, it is not working. First I got a link error saying that it could not find kernel32.lib - I fixed this by changing "Project Properties -> VC++ Directories -> Library Directories" into C:\Program Files\Microsoft SDKs\Windows\v7.1\Lib\x64

    Not I'm getting the error:
    Code:
    1>------ Build started: Project: test, Configuration: Release x64 ------
1>LINK : fatal error LNK1104: cannot open file 'msvcprt.lib'
    So, how do I compile for x64?

    It should be as simple as switching a switch. I don't know what you did.
    In your configuration combobox, select to manage them, and then in the box for Win32, select to create a new and select target platform x64. Copy settings from Win32 and away you go.
    Now you can compile for x64. You don't need the WinSDK. Everything needed should be installed with VS.

    Just note that Edit and continue doesn't work x64 for some idiotic M$ reason. I hate them. And it's the reason I'm probably going to continue writing x86 programs for the time being.

    Outside of your DOS world, your header file is meaningless.
