C++ DirectX skipped when looking for precompiled header

  1. Apr 6, 2014 #1
    Hi all, I main c# and XNA, but XNA is really outdated and requires the player (I'm using XNA for game making) to install it, i wanted to use something windows native so i decided to choose Direct X because i knew some c++. I copied and pasted code to open a blank window to look through but I get the error:

    "Warning 1 warning C4627: '#include <windows.h>': skipped when looking for precompiled header use c:\users\e\documents\visual studio 2012\projects\first directx\first directx\first directx.cpp 2 1 first directx"

    now tried a different code sample from a different site and had the same issue. I was under the impression that direct x being native wouldn't need special include paths. I have $(IncludePath);$(DXSDK_DIR)Include under additional include directories and $(LibraryPath);$(DXSDK_DIR)Lib\x86 under the using directories, what am i doing wrong? I have googled the issue and every variation of my problem takes me to the same stackoverflow page. thanks in advance.

    Hmmm .... googling "visual studio C4627" took me straight to the Microsoft page that explains what the error means, and gives two simple ways to fix it.

    oh, tanks. i just googled the error message and not the actual error value.

    aright second question if no body minds is does anyone know the location of d3dx9.h?

    Have you downloaded the DirectX SDK? Here's a link to the June, 2010 release: http://www.microsoft.com/en-us/download/details.aspx?id=6812

    I'm not sure if that's the latest release or the release that you need for your version of VS. If it's not, do a web search for DirectX SDK. They have a developer center that should have a link to whatever version you need.

    I did all that. i got the error "unexpected end of file, did you forget to add "include "stdfx.h""?" so i added it then i get :
    Error 1 error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup C:\Users\E\Documents\Visual Studio 2012\Projects\hopes run\hopes run\MSVCRTD.lib(crtexe.obj) first

    Give this a shot...
    In the Visual Studio IDE, open Solution Explorer.
    Select the project.
    Right click the project, and select Properties, which should be the last thing on the right-click menu.
    On Property Pages for the project, under Configuration Properties, click C/C++.
    Under C/C++, select Precompiled Headers.
    In the pane on the right, the first thing listed is Precompiled Header, which has a pull-down menu.
    Select Not Using Precompiled Header. The other choices are Create and Use.

    I'm currently using VS 10. If you're using a different version, you might see something different.

    Let me know if that helps out any.

    nope, sorry i thank you for the advie anyway, twas good.

    "Error 1 error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup C:\Users\E\Documents\Visual Studio 2012\Projects\first directx\first directx\MSVCRTD.lib(crtexe.obj) first directx

    thats the new error

    if anyone could please look thorugh it/try compile it to see if they have issues. I really want to learn this engine.

    Your Visual Studio project is configured for a console application. So the linker expects a main() entry point. While your C++ code is for a GUI application, whose entry point is WinMain(). Change the project properties to match your code; or recreate the project, making sure you specify the correct application type (GUI/Windows).

    Thanks. I did everything you guys said, which solved it, but im getting the error:
    MSB6006: "link.exe" exited with code 1120. this is in a win32 project. precompiled headers switched off.
  14. Apr 16, 2014 #13
    MSB6006 is a message from the build system. You should also get a message from the linker, prefixed with LNK, that explains what the error is. Assuming that the exit code would be equal to the error number, and googling for LNK1120, I get this: http://msdn.microsoft.com/en-us/library/z98k84c3.aspx So you still have some unresolved externals, and other messages from the linker should tell you what they are.
