Compilation Error - Windows Environment

[shobha]

Hi all,
  Am trying to compile Netxms-0.2.22 on window environment using VC2005 professional edition.

I am facing the following errors and warnings during Linking process...

Am not sure what the problem is and it would be rely helpful if someone tells me how to solve.

Thanks,

Hi!

Looks like you mix files from different projects into one and trying to compile them as one executable. How do you create VC2005 workspace - by hand or by converting existing VC6 workspace?

Best regards,
Victor

Hi victor,
            I have excluded all the subagents other than ping, and portchecking during compilation.

During compilation i am not trying to port the VC6 workspace to VS2005 workspace.

I am just compiling the whole project modules altogether to bring it as a single executable.I am doing

the work as an windows project in VC++2005.I am in need of your help and suggestions to overcome

the linker errors.Thanks in advance.

Regards,

Shobha.

Hi!

I highly recommend you to try to convert existing VC6 projects (as far as I know, Visual Studio 2005 has built-in conversion functionality for VC6 projects). Currently, there are 59 separate projects in VC6 workspace, each compiling in separate executable or DLL. They are not intended to be compiled into a single executable. The only exception is that it is possible to build monolithic agent with all subagents compiled into it, like static agent on UNIX platforms, but it will require some additional efforts.

Best regards,
Victor
