Compilation error #3

Closed seandoyle closed 5 years ago

seandoyle commented 5 years ago

Hi -

After checking out the code last night I've run into this error - I didn't have this on the earlier version. I can compile/run other programs for the pygamer.

we completely re-factored the library last nite. please check you have all the latest code!

I just deleted this directory and re-cloned it from github. I still get the same error. I'm using Arduino 1.8.9. All of my libraries are updated except for the SPIFlash one - it's at version 2.02 because it wouldn't compile with 3.0.0. The only other changes I've made were setting the config flags ENABLE_EXTENDED_TRANSFER_CLASS and FAT12_SUPPORT to 1 because of the error (I see you have the same error in Travis).

error FAT12_SUPPORT must be set to 1 in SdFat'sSdFatConfig.h

If there are other build items cached somewhere outside the Adafruit_TFLite_Micro_Speech directory I'd be happy to delete them and retry.

I also just tried compiling the micro_speech_json example and get the same error.

I'll look around a bit more but I'm stumped. But I am very honored that ladyada herself responded!

try deleting whatever version of sdfat you have installed and install this version https://github.com/adafruit/SdFat

Thanks. No more SdFat errors - but the original error with kCategoryCount remains:

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

I found the two or three errors...

  1. I downloaded this git repository and loaded the *.ino files directly from the directory that I had downloaded them from. Not sure if this is accepted practice or not.
  2. I had previously downloaded the Adafruit_TFLite_Micro_Speech using the Arduino's library manager. This was at a different version than the one in this repo - which was a cause of compilation errors.
  3. I thought I had followed the instructions from installing pygamer libraries - but when I installed the TinyUSB I must have just unzipped the file into my Arduino/libraries directory without removing the '_master' part of the name.

So - all user errors. Sorry about that - it's been a while since I've been working on arduinos.

all good, this code is under a lot of work :)
