Error building on a Raspberry pi 3B+

[AryehGielchinsky]

Hi

I'm having trouble building on a raspberry pi 3B+ running Ubuntu server 24.04 LTS. I've already seen #2884 but I don't think it is related.

aryeh@pisdr:~/repos/rtl_433/build$ cmake --version
cmake version 3.28.3

CMake suite maintained and supported by Kitware (kitware.com/cmake).

aryeh@pisdr:~$ uname -a
Linux pisdr 6.8.0-1020-raspi #24-Ubuntu SMP PREEMPT_DYNAMIC Sun Feb 23 08:39:32 UTC 2025 aarch64 aarch64 aarch64 GNU/Linux

Ran sudo apt-get install libtool libusb-1.0-0-dev librtlsdr-dev rtl-sdr build-essential cmake pkg-config as well as sudo apt-get install libssl-dev because the cmake -B build wasn't detecting openssl, but the build still fails at 6%.

Any ideas how I can complete the build?
Thanks

I don't see any error. It looks more like the compiler crashed?

[AryehGielchinsky]

I'm not so familiar with building, so I probably used the wrong terminology.

Could this be caused by the Raspberry pi 3B+ having only 1gb of ram and a weak processor? Is there anything I can do about it?

Ultimately I'm looking to use rtl_433 version 24.10 or later (which has the Arad Master Meter water utility meter).

[zuckschwerdt]

The Raspberry PI 3B+ with 1GB is usually fine. So far I only ever tested server OS variants without a running desktop. It might be a RAM problem if the desktop is already using too much RAM, not sure.

If you can use Ninja as build tool (sudo apt-get install ninja-build) and limit to 1 process as Greg wrote, i.e. cmake -GNinja -B build && cmake --build build -j 1

If it is a OOM error then dmesg should show that as "killed process" or such.

[gdt]

It's a bug in cmake if it does parallel without explicltly being told to, but people these days are writing software without having completed their apprenticeship on low-memory systems. I don't mean 1 GB -- I remember multi-user Unix (as in most of 10 terminals) in 128 kB.

[gdt]

Definitely compiler process failed and this is not about rtl_433 sources.

• Configure some swap space
• FIgure out if cmake is deciding to run multiple jobs and parallel and make it stop, so you only have one
• read /var/log/messages or wherever your os puts that content

[AryehGielchinsky]

Thank you, this got it working.

1. adding 1GB swap ram
2. using ninja-build with 1 core

It took a while, but eventually finished building, and now works properly.
