I followed all the instructions on [gnuradio.org](http://gnuradio.org) to build gnuradio+uhd on XP+SP3 with MinGW Everything went well. uhd\_fft.py shows spectrum window, all well. However, when I tried gnuradio-companion, I got the following errors. Any ideas? I thought someone had success with grc on MinGW. C:/MinGW/msys/1.0/local/bin/gnuradio-companion:51: GtkWarning: Could not find th e icon ‘gnuradio-grc’. The ‘hicolor’ theme was not found either, perhaps you need to install it.

Probably some mismatch between mingw paths and native windows paths?

Also /usr/local/share/gnuradio/grc/blocks does not work. Must use windows style path. Thanks Josh for the prompt support.
