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

[Barry Duggan]

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
