2B direwolf gpio errors

I'm getting an error when I try to use direwolf with GPIO configured for PTT.
I'm running Raspberry Pi OS on a Pi 2B.

开云体育Hello Jim, A recent Raspberry Pi OS upgrade made many disruptive changes including deprecating the old way of interfacing to the GPIO pins.? To resolve this for Direwolf you need to compile a new Direwolf using the Direwolf DEV branch which will bring you up to the 1.8-D version: ?? Section 7.2.2 ?? --David KI6ZHD On 07/23/2024 09:49 PM, Jim KX0U wrote:

Another option is downgrading the kernel to 6.1.74 which was the last kernel with the deprecated GPIO. A lot more software will be affected for GPIO access and this fix will fix it for all
sudo rpi-update d86b5843d68b9972a5430a6d3da1b271cfc83521

Thanks, David, for the information. I have compiled direwolf 1.6 according to the steps listed in the PDF you provided a link to.? However, I didn't get the "Includes optional support for:? libgpiod" I should have.? (I did successfully install gpiod and libgpiod-dev prior to building direwolf.) Can anyone recommend additional steps I should take to get the required support compiled into direwolf? 73, Jim?

开云体育Hello Jim,You need to install the required dependency packages and then compile the Direwolf 1.8-DEV (not 1.6) meaning the DEV branch of Direwolf: ?? --David KI6ZHD On 07/24/2024 08:44 PM, Jim KX0U wrote:
