Hi
find the number of CPUs in your system with command:
cat /proc/cpuinfo | grep processor | wc -l
don't use all available CPU when using make -j (example make -j3 if you
have 4 CPUs)

Hi Sarandis,
In the first version of your attempt, I’ve also seen this problem
It is caused by your laptop running out of memory during the
make -j 4
step. It can probably be fixed by running
make
instead. The -j 4 command causes 4 simultaneous threads to run, using up
all the memory.
It will take hours to “make” however.
Best regards
Glen

sudo apt-get update
sudo apt-get install gnuradio
I want the 3.8 version. Thanks
