Release build error LNK2019

Droopy Toon

Hi,

I think it is a FAQ but I found no answer to my problem.
I created a C# program that called some C++ legacy code.
I created 2 projects :

1) a DLL (IPRCommWrapper .dll) including an unmanaged C++ wrapper for
legacy code and a managed C++ wrapper to allow C# to call this unmanaged
wrapper
2) a C# Win application

In Debug mode, everything works fine.
When I try to build in release mode, I have the following error :

"libcmt.lib(crt 0.obj) : error LNK2019: unresolved external symbol _main
referenced in function _mainCRTStartup ".

here is the output from the build log :

Creating temporary file

.\Release\TrspP ortManaged.obj
.\Release\app.r es
]
Creating command line "link.exe
@c:\Projects\IP RManaged\IPRCom mWrapper\Releas e\RSP000017.rsp "
I suppose I did not choose appropriate options (though I selected
"NoEntry" as DLL entry point).

Thanks in advance for any help.

Build Problem - Debug Vs Release

by: David++ | last post by:

Hi there, I have built a DLL in Visual C++ 6. When I build the DLL it builds fine for the debug version of the DLL (and this DLL works fine), however, I seem unable to build a Release version of the DLL. If I do a 'Batch Build' and select both Debug and Relase versions for building it will build the debug version but throws up errors for the Release version. For example, the output I get for a Batch Build is this - ...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
