If you use a swap file, it won't crash. However, there may be a more
optimum number of cores to use rather than all four.

Hi Ron,
Thanks for the suggestion. My experience is that the -j4
works for a while on a Raspberry PI 3B+, but eventually
runs out of memory on some files and the whole PI crashes.
-j4 might work on a 4 GB PI 4 though.
Best regards,
Glen

You can reduce build time significantly by using all the cores in your
CPU. This is done by using the -j parameter with the make command. Set
the parameter to the number of available cores. For the Pi 3B+, the CPU
has four cores, so:
make -j4

Hi Glen,
With the help of many of our friends here, I was able to build 3.8
from scratch on a Pi 3B+. Here are my notes from that effort:
Build gnuradio on Raspberry Pi 3B+
Author: Barry Duggan
31 July 2019
OS: Raspbian Buster with desktop and recommended software
32GB microSD
A. Load prerequisites
sudo apt-get update --allow-releaseinfo-change
sudo apt-get upgrade
sudo apt-get install git cmake g++ libboost-all-dev libgmp-dev swig
python3-numpy
sudo apt-get install python3-mako python3-sphinx python3-lxml doxygen
libfftw3-dev
sudo apt-get install libsdl1.2-dev libgsl-dev libqwt-qt5-dev
libqt5opengl5-dev python3-pyqt5
sudo apt-get install liblog4cpp5-dev libzmq3-dev python3-yaml
sudo apt-get install libpthread-stubs0-dev
sudo pip3 install click-plugins
D. Set up swap file
sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
- To make this permanent, add this line to /etc/fstab
/swapfile none swap sw 0 0
C. Clone repository
cd
git clone --recursive https://github.com/gnuradio/gnuradio.git
D. Build
cd ~/gnuradio
mkdir build
cd build
(this next command is all on one line, starting with cmake and ending
with ../)
cmake -DENABLE_GR_UHD=OFF -DCMAKE_INSTALL_PREFIX="/usr/local"
-DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3 ../
make
sudo make install
sudo ldconfig
Of course, if you want UHD, leave out the "-DENABLE_GR_UHD=OFF".
It took about eight hours total.
Good luck! Let me know how it went.
Best wishes,
