Trouble building (& using) pinephone-keyboard tools

[carterza]

I'm trying to build the pinephone-keyboard package on PostmarketOS, so I can see the keyboard's battery with one of its commands. After installing php and gcc to solve the dependency errors I was getting, I got stuck on one I couldn't figure out:

Code:

In file included from i2c-inputd.c:22:
common.c:20:10: fatal error: linux/usbdevice_fs.h: No such file or directory

I did a search and found the file in a GitHub repo that's supposed to be a Linux kernel - I don't know much on the subject, but I assume this means getting the tools to compile will be more complicated than a simple apk install... Unless, by some miracle, make's just not finding the header file hidden in some system folder

Anyone got any ideas? Cheers

Install the

Code:

linux-headers

package.
