mixing c file with c++ file

Hi,

I have two projects and want them to get together. But I have a problem with mixing c and c++ files.

I get this error while compiling:

process.c fatal error C1853: 'Debug/service.pch' precompiled header file is from a previous version of the compiler, or the precompiled header is C++ and you are using it from C (or vice versa)

I try to solve my problem with this ms paper:
http://support.microsoft.com/kb/126717
but nothing there really work.

Can somebody help me with this problem.


Thank you for help,
keeper

p.s. I use MS Visual Studio 2003 and its internal compiler.

Goto project settings and turn OFF pre-compiled headers.

Hmm now I get these errors after I mark the option Not Using Precompiled Headers:

cerrno(18): error C2143: syntax error : missing '{' before ':'

and

cerrno(18): error C2059: syntax error : ':'

and

cstdlib(19): fatal error C1003: error count exceeds 100; stopping compilation

Are you including any of your headers before the system headers?

Did you delete the "Debug" and "Release" directories, then try "Rebuild All..." ?

I have under the option Additional Dependencies these two psapi.lib ntdll.lib libaries.

The only header I include before the system headers is #include "stdafx.h"

I delete the Debug directory rebuild all, but I have the same errors I mentioned above.

Making a complete new project without the stdafx.cpp and stdafx.h file and with Not Using Precompiled Headers on, I get these errors:

test error LNK2005: _strcat already defined in ntdll.lib(ntdll.dll)

test error LNK2005: _atoi already defined in ntdll.lib(ntdll.dll)

test error LNK2019: unresolved external symbol "int __cdecl InjectDll(void *,char const *,int)" (?InjectDll@@YAHPAXPBDH@Z) referenced in function "void __stdcall ServiceMain(unsigned long,char * * const)" (?ServiceMain@@YGXKQAPAD@Z)

test error LNK2019: unresolved external symbol "void * __cdecl GetProcessHandle(unsigned long)" (?GetProcessHandle@@YAPAXK@Z) referenced in function "void __stdcall ServiceMain(unsigned long,char * * const)" (?ServiceMain@@YGXKQAPAD@Z)

Can you help me with this better?

you have to make sure all your libraries and your project are using the same threading/linking model

i.e Multi-threaded debug DLL, or Multi-threaded DLL, or Mutli-threaded debug (static) or Multi-threaded (static)

I have test all the different versions available, but I get always the error LNK2005 and error LNK2019 I write in my post above.

And I dont know what type of lib ntdll.lib is.

If somebody can please download the programm one could better see were my problems are. I don't know what I can describe more about the errors that appear because everything I try to solve the problem get me new errors. Probably its a little fault in the code and with the programm you see it better as with my description of that.

Thank you,
keeper

get it working :)

It was just a little

Code:

---

extern "C"
{
        #include "x.h"
}

---

Thank you all for your help :)
