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

Hi Ron,

Thank you for your excellent suggestion! I was able finish the last half
of the make in 3 hours with no problems :)

In looking at your suggestion to make it permanent, I am concerned about
the comments in fstab:

"""
proc /proc proc defaults 0 0
PARTUUID=e625713b-01 /boot vfat defaults 0
2
PARTUUID=e625713b-02 / ext4 defaults,noatime 0
1
# a swapfile is not a swap partition, no line here
# use dphys-swapfile swap[on|off] for that
"""

Do I need to do something else?

Thanks again.

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
