Hi.
If you are trying to get GnuRadio compiled on Windows then I'd suggest doing a
"native" build rather than using Cygwin. Despite what it says here:
http://gnuradio.org/redmine/projects/gnuradio/wiki/WindowsInstall GR 3.7 *will*
build properly using VisualStudio and the result is fully usable (with a tiny
tweak, see my bug report here: http://gnuradio.org/redmine/issues/799). While
the install/compile process is complex, and has a very steep learning curve, I
found it to be more successful (eventually!) than the Cygwin approach,
(although if you are new to this like I was, don't expect to get it working
without a few weeks effort!) I managed to get a working GR 3.7.7.1 compiled
from source (with the the RTLSDR and OsmoSDR blocks) about 6 weeks ago, and
It's been working with my HackRF Blue (and RTL dongle) pretty well.
I would say though that's the process is enormously painful! The Pothos project
install seems *much* more polished: https://github.com/pothosware/pothos/wiki
(with just a single installer for everything! In an ideal world this is what
the GnuRadio installer should be aiming for I think), but at the time it didn't
seem easy (or perhaps even possible) to add the OsmoSDR blocks to Pothos that I
needed to support my HackRF Blue.
CE.
