Can't compile firmware

[tmartin]

I've just fitted the 3dtouch auto levelling sensor and I'm seeking to update the firmware. I've downloaded the indicated file: I3ProW.zip and pulled it into Arduino (v 1.8.5) and tried to build it. Unfortunately, it fails with the errors posted below. Can anyone identify what the problem is?

Thanks.

Tony

For any other noobs who find difficulty with the firmware package, as downloaded.

The first raft of errors from Arduino IDE occurred because I was working on the downloaded marlin.ino (on linux). By pulling it in as a template and saving it as marlin2.ino I was able to save changes.

To overcome the problem with LiquidCrystal.h I installed the libraries LiquidCrystal and U8glib from the Arduino IDE library manager. This overcame the error listed in the second part of the included error diagnostic.

The compile failed at this stage due to the presence of a definition of 'fpos_t' in SdBaseFile.h (and SdBaseFile.cpp) which clashed with a similar definition in stdio.h. I renamed the SdBaseFile definition to 'fpos_t_sd' and all compiled well.

Now that the firmware is flashed, I must troubleshoot the strange behaviour...
