A friend was attempting to build gnuradio on Linux Mint 17.1 32-bit. I run 64-bit Linux Mint and did not have this issue since it is specific to 32-bit builds.

If you’re attempting to build gnuradio on a 32-bit system system, whether it be Ubuntu or Mint or something else, you might not be able to build gnuradio without issues. This applies only to the latest gnuradio available as of 12/26/2014. The issue will probably be fixed in future versions.

To resolve this issue so that you can rebuild gnuradio, scroll to the bottom.

Solution (which I found here):

A fix for this is to change line 39 in volk/kernels/volk/volk_64u_popcntpuppet_64u.h

from

#ifdef LV_HAVE_SSE4_2

to

#if LV_HAVE_SSE4_2 && LV_HAVE_64

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.

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
