Usually this is caused by leaving the _ATL_MIN_CRT definition in your project settings when your code uses the C runtime libary startup code, either directly or indirectly. So, when I try to link this library to produce the EXE.

My vote is 5 for your answer. if you wrote your own replacement CRT, or if you are targeting a system without CRT), and none of these apply to you. So, COleServerDocX is >derived >from COleServerDoc. So, even if you instruct the linker to tell the OS not to call it, that function exist and places a call to "main" in the symbol table.

What do you call "intellectual" jobs? a fantastic read I thik what I would suggest is to set the Fortran > Library > Runtime Library option to "Multithreaded" (not Debug Multithreaded) and see whast you get.
I built the sqlite3.lib in visual studio 2008 and i got the DragonFireSDK.lib file from the SDK team. i am quoting this because when i rename the file to .cpp and remove the entry point .its builds without linker errors. libiomp5md.dll is the OpenMP support. It is automatically added to PATH when you install the compiler. If you copy the application to another system, you need to install the Intel redistributables I Read on msdn about this but its only explain how i shold solve the problem in Release version.
The correct way is to just use the VC++ 8.0 Redistributable Package like you're supposed to. this page Reply With Quote Quick Navigation Visual C++ Programming Top Site Areas Settings Private Messages Subscriptions Who's Online Search Forums Forums Home Forums Visual C++ & C++ Programming Visual C++ Programming Visual Fortran Unresolved External Symbol What does the pill-shaped 'X' mean in electrical schematics?

Error Lnk2019: Unresolved External Symbol _main Referenced In Function ___tmaincrtstartup
There is a _DllMainCRTStartup function which is set as the entry and one more thing to note is the file is a .c file . This way, others will be able to look exactly at what you are looking at. I get the error that _main is undefined, and it is needed by libcmt.lib(crt0.obj). http://cygnussoft.com/unresolved-external/unresolved-external-symbol-lnk2001.html Of particular importance is the fact that your library is missing _AFXDLL.

If you use a function that requires the CRT startup code to operate properly, you will get the following linker error: Copy LIBCMT.LIB(crt0.obj) : error LNK2001: unresolved external symbol _main Providing check over here But when i use both the above libraries i get the linking errors.

Insults are not welcome. Hope these information is enough.
As a consequence a function named "main" must exist somewhere to let the linker to resolve that name. Because I still can debug with "Multithreaded".
