I encountered a problem building Wireshark today on a Windows XP box
that seems to have been encountered before, but searching on the web
yielded no answer. For that reason, I thought I'd describe both the
symptoms and the fix so that the next individual to encounter this might
be able to find this solution a little easier.
The problem manifests itself like this:
Extracting C:\WIRESH~1/zlib123ws.zip into C:\WIRESH~1/zlib123
ERROR: Couldn't unpack C:\WIRESH~1/zlib123ws.zip
NMAKE : fatal error U1077: 'C:\cygwin\bin\bash.EXE' : return code '0x1'
When I unzipped the file from within a cygwin shell, everything worked
just fine. Eventually, I figured it out and it turned out to be quite
simple. I had another (old) version of unzip in the C:\WINDOWS
directory. By coincidence, the older version worked just fine on all of
the library files before that one, but failed on zlib123ws.zip because
it happened to use the "enhanced deflate" compression scheme which the
old version of unzip could identify but not use.
If anyone has this problem in the future, there are a few things to try
that may help them out. First, the output of verify_tools pointed to
the version it was actually using, had I read it more carefully. With
an up-to-date cygwin, the line *should* show:
Second, one can temporarily change the tools/win-setup.sh file from this
pair of lines:
