Dear all,
I’ve been using GR on Linux for some time, and thought I’d compare its
performance on ‘that other’ OS.
A few weeks ago I checked out the latest from the repo and managed to
compile all that could be compiled on Windows (7, 64-bit) using the
latest
32-bit release of MinGW/MSYS and its bundled packages. The unbuilt
components are those that explicitly require a different platform/build
environment (i.e. USRP2, gcell & related). Qt, wx, GTK and GL GUI
apps/components all work too (including GRC).
The existing guide on the GR wiki
(http://gnuradio.org/redmine/wiki/gnuradio/MingwInstallMain) was an
excellent starting point, however additional source modification and
configuration was necessary (e.g. creation of PkgConfig files).
Some simple tests with a USRP I indicated everything works well and
performs
similarly to a Linux build - as you would expect! Linux still feels
slightly
snappier though (WOW64?). There is also that issue where you have to
re-connect the USRP after the firmware has been programmed.
I’m wondering how many people actually use GR under Windows? (I’m
guessing
it’s a minority!)
If it’s helpful to anyone, I can package up my build notes, .pc files
and
patches, and put them online.
Thanks for keeping GR (almost entirely) cross-platform!
