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 ?
