Re: [Discuss-gnuradio] Build GR 3.8 from source

[Ron Economos]

When building GNU Radio on small systems, it's very easy to run out of 
memory (especially when building swig files). The remedy is to create a 
swap file.

sudo fallocate -l 2G /swapfile

sudo chmod 600 /swapfile

sudo mkswap /swapfile

sudo swapon /swapfile

To make is permanent, add this line to /etc/fstab

/swapfile  none  swap  sw  0  0
