Airwaves

I’m running Linux Mint 17.1 and had already installed git, pybombs, gnuradio, and OP25 per instructions kingly given by PiccoIntegra in throughout this thread on the RadioReference forums.

I decided I wanted to install gqrx.   Should be simple.   Switch to your ~/pybombs directory and type in:

./pybombs install gqrx

However, for me it wasn’t quite so easy.   After doing this, the installation failed with the following information below.

make: *** [gqrx] Error 1
Build failed. See output above for error messages.

So, I did some searching on the internet and found out that unless you compiled libboost stuff from source, the -mt is no longer needed.

To fix this issue:

1. Edit ~/pybombs/recipes/gqrx.lwr, make the following change, and then save:

Change:   qmake BOOST_SUFFIX=-mt

To:   qmake BOOST_SUFFIX=

2. Change back to your pybombs directory

mike@LinxMinut ~ $ cd ~/pybombs

3. clean the previous build data for gqrx and then rebuild gqrx

mike@LinuxMint ~/pybombs $ ./pybombs clean gqrx
