Error in installation of gqrx

GNU Radio
1

Hello all,

I tried to install gqrx using PyBOMBS. I have GNU Radio 3.7 installed
using
PyBOMBS.

*manu@radio1:bin$ ./gnuradio-config-info -v
3.7.2git-0-gd19aa281

Then I did

*manu@radio1:pybombs$ ./pybombs install gqrx
*
But I got the following output.

I’m sorry if this has been discussed before. Any thoughts?

I have no idea how such error messages occur …
Can you check to see if the missing headers are in
/usr/local/include/gnuradio/ or really missing?

Hi Alex,

I am using PyBOMBS for installation. PyBOMBS installed GNU Radio(3.7) to
a
local directory instead of /usr/local. In my case this directory is
“/home/manu/gr/target/”. The files missing are there in
“/home/manu/gr/target/include/gnuradio”, while they are not found in my
old
installation (3.6.* inside /usr/local). I want gqrx also to work with
the
new (3.7), and I used PyBOMBS to install.

So it could be that the qmake is not able to locate the header files in
“~/gr/target/include/gnuradio”. Is there a way to specify that in the
recipes?

The gqrx build system based on qmake uses pkg-config to find the
gnuradio dependencies. The environment to find the pkg-config scripts
is set up by pybombs; however, if you have gnuradio 3.6 installed
system wide in /usr/local/ the old pkg-config files may interfere with
pybombs.

I see no other safe option than to remove gnuradio 3.6 from
/usr/local. If you still need gnuradio 3.6 you can install it under a
prefix other than /usr/local. As long as you have gnuradio 3.6 in
/usr/local it will interfere, not only with gqrx but other
applications as well.
