Install GNU Radio 3.6.4 on MacOSX with package conflicting warnings

GNU Radio

Hi, Michael,

I try to install GNU Radio 3.6.4 on MacOSX 10.8.2 with MacPorts 2.1.3 by
the following commands:
$ sudo port install gnuradio +full configure.compiler=llvm-gcc-4.2

During the installation, I have to “port -f activate qwt” to proceed to
install GNU Radio 3.6.4. This seems to be fine and I can run
gnuradio_companion without problems. And then I try to install rtl-sdr
by
$ sudo port install rtl-sdr

I got this message, which indicates conflicting between qwt and qwt52:
============================== MESSAGE START

============================== MESSAGE END

What should I do to have gnuradio, gr_filter_design, and rtl-sdr built
by MacPorts at the same time? Thanks.

Hi Albert - GNU Radio (et.al.) will work with QWT 5.1 or later,
including 5.2 or 6.0 (in theory; configuration using 6.0 didn’t work the
last time I tried, but I could coerce binaries to work after linking
with 5.2 and then changing DYLD loading to 6.0). I know of no specific
port requirements for QWT (5.1; I might be wrong), and qwt52 is (IMO)
more stable / better option. I have all of these installed and passing
check/test using qwt52, so it can be done.

Probably the best way to do this is to uninstall all of the SDR ports
(gnuradio, rtl-sdr, others), then also uninstall qwt and py27-pyqwt.
Now, install qwt52 (defaults are probably OK: “sudo port install qwt52”)
and then py27-pyqwt (“sudo port install py27-pyqwt”). Now install
gnuradio (+variants), rtl-sdr, and others.
