Linux Timblenovo 4.15.0-33-generic #36-Ubuntu SMP Wed Aug 15 16:00:05 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I'm getting errors about hid_input_report(... size ...) and hid_report_raw_event(... size ...) needing to be u32 instead of int, and (after trying to fix those) asking whether instead of signal_pending, I mean timer_pending.

I attach the make.log; here's the output:

While I'm writing, it would be helpful if you could add a few lines to 'how to install' - I haven't needed to fiddle with kernel modules for several years, and the tools have changed!

sudo apt-get install linux-source dkms libelf-dev
gem install fpm
make
sudo dpkg -i build/magictrackpad2-dkms_1.0.0_all.deb

I just noticed the libelf stuff at the start of the log - those signal_pending and similar errors persist.

make.log

Never mind, I found https://github.com/rozza/magictrackpad2-dkms which has a fix. Especially once I noticed the version number has been bumped too.
