Error compiling under Trixie for Raspberry PI 3B+

[ricorico94]

Hi,
I'm trying to re-install MySensors on a fresh installation on Raspberry Pi 3B+ using Trixie.
I faced several errors. I could solve a couple, but I'm still blocked.
What I solved:

• initial stropts.h error.. so I used development branch (git clone https://github.com/mysensors/MySensors.git --branch development )
• then the problem in ATOMIC Block

./hal/architecture/Linux/MyHwLinuxGeneric.h:106:50: error: ambiguating new declaration of ‘uint8_t __hwLock()’
  106 | #define ATOMIC_BLOCK for ( ATOMIC_BLOCK_CLEANUP, __hwLock(); \

I think I solved I solved it by replacing a coupe lines in MyHwLinuxGeneric.h file as per advice of some other posts ([https://github.com/mysensors/MySensors/issues/1557 )

then compilation was ok, but running I got GPIO error message:

~/MySensors $ sudo ./bin/mysgw

I found this post : link text which had similar type of error and pointing to a commit #1562
Unfortunately, I'm not understanding very well how github works. I tried to download the 4 different modified files and replace the original ones, one by one (hopefully I downloaded correct ones, I don't feel very comfortable) .
Then I installed also the new lib ( sudo apt-get install libgpiod-dev ), launched again the config

sudo ./configure --my-transport=rf24 --my-rf24-irq-pin=15

but when I launch sudo make, then I can't compile anymore:

What do I do wrong ?
Thanks for your help..

Hi again.
I found another post (#1610), which seems referring to the previous one (#1562) and to TRixie.
So I replaced the 6 files by ones found in Files of #1610.
Now I can compile with no error, but when launching mysgw, I get an error :

:~/MySensors $ sudo ./bin/mysgw
Oct 25 12:56:48 INFO  Starting gateway...
Oct 25 12:56:48 INFO  Protocol version - 2.4.0-rc.1

Oct 25 12:56:48 DEBUG TSF:WUR:MS=0
Oct 25 12:56:48 ERROR Failed to request GPIO line

To clarify my setup, I wanted to run the MySensors gateway on my same Raspberry Pi 3B+/Trixie than my Domoticz (same setup than before under Bullseye..)
Any idea ?

I can't really help with the linux code, but if one of the old heads doesn't weigh in, try Ai. This is the kind of thing AI is good at. "I was running this under bullseye, but when I switched to trixie, I get these errors". I've used github copilot for errors similar to this on other programs with good luck. Usually takes about 3 iterations to get to the real problem / solution. When you get it running, don't forget to submit a PR to fix it for MySensors.

Looks like the library for the GPIO isn't working. Try to get it working with Raspberry Pi OS
