Wireshark · Wireshark-dev: [Wireshark-dev] Unresolved symbol problem with a tap (__imp__a_global_variant)

["Michael Lum" <Michael.Lum@xxxxxxxxxx>]

Hello,

I am using:

Windows XP
Visual C++ 6.0

I have built a few versions of ethereal successfully (not wireshark yet).

I am currently trying to rebuild ethereal-0.99.0 after modifying the
ANSI A-interface dissector, packet-ansi_a.c

I am getting the following errors but I can't figure out what the problem
is.
(I have tried 'distclean' but it didn't make a difference.)

Part of the problem is that there are no complaints about
'ansi_a_ios401_bsmap_strings' and 'ansi_a_ios401_dtap_strings' which
are defined in the exact same manner!(?)

This is from *** packet-ansi_a.h ***

The command 'nmake -f Makefile.nmake' results in the following:

Any help would be greatly appreciated.
Thank you.
