R6034: An application has made an attempt to load the C runtime library incorrectly

I am getting this R6034 error when running program that I just updated (and cleaned) from VS2003 -> VS2008. To be more exact:

"R6034: An application has made an attempt to load the C runtime library incorrectly."

It seems to happed almost at the same place all the time when running. I have no really idea why but I tried some s开发者_StackOverflow中文版uggestions I found when googleing this. For example adding the msvc dlls, but that didn't work.

Any help on why this error occurs would be great. Thanks

Starting from Visual Studio 2005 you must refer to the C Run Time using a manifest file. Referring to the DLL's by just putting them in the path will give the above error.

The manifest file will look like this:

<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
<assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'>
  <dependency>
    <dependentAssembly>
      <assemblyIdentity type='win32' name='Microsoft.VC80.DebugCRT' version='8.0.50727.4053' processorArchitecture='x86' publicKeyToken='1fc8b3b9a1e18e3b' />
    </dependentAssembly>
  </dependency>
</assembly>

You can use the MT command to integrate the manifest as a resource in the application, but that's not mandatory. It's also allowed to have the manifest besides your application (as MYAPP.EXE.MANIFEST).

The following test program:

#include <iostream>
#include <crtdefs.h>

void main()
{
std::cout << "Hello World" << std::endl;
}

Compiled using these commands (Visual Studio 2005):

cl /EHsc /MD /c test.cpp
link test.obj

Create the executable (TEST.EXE) and a manifest file (TEST.EXE.MANIFEST) that looks like this:

<?xml version='1.0' encoding='UTF-8' standalone='yes'?>
<assembly xmlns='urn:schemas-microsoft-com:asm.v1' manifestVersion='1.0'>
  <dependency>
    <dependentAssembly>
      <assemblyIdentity type='win32' name='Microsoft.VC80.CRT' version='8.0.50727.4053' processorArchitecture='x86' publicKeyToken='1fc8b3b9a1e18e3b' />
    </dependentAssembly>
  </dependency>
</assembly>

I didn't try this with VS2008, but this should probably work as well.

Hope this is enough to get you started.
