When building Wireshark under Windows 7, I receive the error above after changing to the wsutil directory. I'm not familiar with biulding DLLs, but I would have thought the DllMainCRTStartup function should have been found in one of the *.c files within wsutil - but it isn't. Here's the output I get from running the "nmake -f Makefile.nmake all" command: <previous packages="" built="" correctly...=""> cd wsutil "C:Program Files (x86)Microsoft Visual Studio 8VCBINnmake.exe" / -f Makefile.nmake Microsoft (R) Program Maintenance Utility Version 8.00.50727.762 Copyright (C) Microsoft Corporation.

One Answer:
I don't specifically know what the problem is.... I have no troubles when building with Visual Studio 2008 (VC9). I notice you appear to be building with Visual Studio 2005 (VC8). Have you commented / uncommented the proper lines in config.nmake to indicate the compiler you are using ? (config.make as distributed indicates that Visual Studio 2008 (VC9) is being used). Is there any particular reason you are using VC8 ? Wireshark is built using VC9 these days. answered 02 Dec '10, 08:50  Bill Meier ♦♦ edited 02 Dec '10, 09:19 |
Yes, I modified the config.nmake file to account for the correct version of VS. The reason I'm using VC8 is because that is the version I own - and I can't afford to upgrade at the moment.
I did note that even though my user account has administrator privileges under Windows 7, there are times that subdirectory creation fails. I will be backing out the various tools (for example, TortoiseSVN never worked properly) and will be re-installing everything specifically as administrator.
Just as an FYI:
A free version of VS2008 (VS2008EE) can be downloaded from Microsoft.
See: http://www.wireshark.org/docs/wsdg_html_chunked /ChSetupWin32.html#ChSetupMSVC
Yep - tried that. Downloaded the VS2008 and installed it. Did a "distclean" - made sure I ran the correct batch file to set up the path, yada yada - and still bombed out at the same point with the same error. I ran all this as the "adminstrator" under Windows 7.
BTW: I did remember to change config.nmake back to the correct VS2008) version before doing the nmake ... all.
