Build Problem: gr-osmosdr and FreeBSD

Hi All:

I have gnuradio 3.6 running under FreeBSD 9.2.  This is the latest port of gnuradio on that platform.

I would like to build gr-osmosdr so that I can use my Realtek USB dongle under gnuradio-companion.

I followed the procedure at

1) Got the source:
git clone git://
cd gr-osmosdr/

2) Followed the direction for use with gnuradio 3.6:
git checkout gr3.6

3) Created the build environment:
mkdir build
cd build/
cmake ../
4) However, "make" fails with the following error:
[ 24%] Building CXX object lib/CMakeFiles/gnuradio-osmosdr.dir/rtl/
/home/kevin/gr-osmosdr/lib/rtl/ In member function 'virtual osmosdr::freq_range_t rtl_source_c::get_freq_range(size_t)':

Stop in /usr/home/kevin/gr-osmosdr/build.
*** [all] Error code 1

Stop in /usr/home/kevin/gr-osmosdr/build.

I did some research on the error and the missing declaration.

While there is a previous post from another person who experienced this error, I can't follow the proven solution of "upgrade to gnuradio 3.7" as I expect that this would not be trivial, and in fact very complex, under FreeBSD.  I have no porting/port conversion experience.

Just thought I'd ask if anyone else has experienced this, and whether there is a known solution.
