I have tried this with both the release 3.0 and the 3.0rc3 but get the
same message. Before I updated my cygwin package, I used the same
source and was able to build the GNUradio code fully without errors
(But the programs didnt work though!!).
Given the above two issues, it appears as though your Cygwin installation needs some correcting.
Even I thought of the same thing and I have tried with cygwin packages
downloaded from almost four or five mirrors…From what you say,
the problem seems to be with cygwin package, but how do I rectify it??
Can you be more specific??
