Hi Jean-Michel!
Fully agree, if a build takes 8 hours, your system isn't the system you
should build on, even if it "feels" like a full PC!
However, at the time, I don't have anything better to offer to Barry,
seeing that Raspian AFAIK doesn't ship current GNU Radio, and setting
up an OE build di
Here's what I use for the BeagleBoard X15. Should be adaptable to other
boards by changing -march and -mtune.
cmake -DCMAKE_CXX_FLAGS:STRING="-march=armv7-a -mfloat-abi=hard
-mfpu=neon -mtune=cortex-a15" -DCMAKE_C_FLAGS:STRING="-march=armv7-a
-mfloat-abi=hard -mfpu=neon -mtune=cortex-a15" ../
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 Gle
Thanks Barry,
Those are great notes.
I will try to follow them.
However it would be great if I could start from an image of the Sd card.
One issue with SD card images is to remember to remove passwords from
browsers
I am also using a 32GB card, but it compressed very well, down to 2.5GB

You need to specify the right cmake toolchain in order to enable the use of
NEON kernels.

I would hope this list would stop promoting building on the target
embedded system.
Embedded system development should never, ever, attempt compiling
on the low power target but rather figure out how to cross-compile
from the powerful host for generating binarie
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:

Thank you very much!!
This was the problem.
Now, it works fine.
