Pinephone Keyboard Utilities on postmarketOS

[elof]

Hi,

I have my Pinephone Keyboard working really well with my Pinephone running postmarketOS edge.

However, I cannot check the current charge of the keyboard battery.

The device does not show up as /sys/class/power_supply/ip5xxx_power 
I am unable to compile the ppkb utilities as sdcc is not available in the pmOS.

Does anyone running pmOS on the Pinephone know how to tackle this?

Thanks in advance!

P.S.:
I've searched the forum for

• ppkb postmarketOS
  
• sdcc postmarketOS
  
• ppkb pmos
  
• sdcc pmos
  

but haven't found anything so I thought I'd open this thread

http://sdcc.sourceforge.net/ ?

Have you successfully built it from source on pmOS yet? Unfortunately there is no aarch64 linux build afaik.
I'd love to hear how you did it. I can't find straightforward instructions for this and I've so far not been successful in my attempts.

Currently the configure script fails stating
"C compiler cannot create executables".

This is with gcc-11.2.1 on pmOS edge.
