Greetings all,
I realized after reading the developer guide that Visual Studio .NET (VC7) and its C compiler is discouraged because of MSVCRT70.dll but I do not plan on distributing my builds beyond my immediate development team and really I just want to be able to modify/test an existing packet dissector.

That being said while building under Windows XP Professional I hit some linker errors just a few seconds into the build:

Creating library wiretap-0.3.lib and object wiretap-0.3.exp

nettl.obj : error LNK2001: unresolved external symbol __imp___errno
network_instruments.obj : error LNK2001: unresolved external symbol __imp___errno

and so on and so forth for several screens. There appears to be an issue with the C runtime library (errno, strncmp, fwrite, etc. all have similar linker errors).

Has anyone seen this before and is willing to break the Visual Studio .NET glass ceiling to lend a thought?

Kind regards,

Ben
