ESP8266 Compilation issue #16

Closed ronguest closed 5 years ago

ronguest commented 5 years ago

I am seeing a compile failure specific to the ESP8266 when using the included example graphicstest_featherwing. Reproduced by installing a new Arduino IDE 1.8.8, downloading fresh copies of the GFX and HX8357 libraries, setting the board type to Feather M0 - compiles without errors. Change the board type to Feather HUZZAH 8266 and the compile will fail with the below error. In looking at the GfX repo I see some changes were made last week specifically for the 8266. I looked at the copy of the GfX library source and confirmed the changes are in the copy on my machine. I don’t understand the libraries enough to know if the problem lies in the GfX library itself or HX8357. But since the error is reported on the HX8357 at compilation I’m filing it here.

Here are the compile errors:

I was able to recreate. There's a #if that removes the constructor for ESP8266. https://github.com/adafruit/Adafruit-GFX-Library/blob/5f38af166fdb1faf4cea2ffd67857d8b09cd66f5/Adafruit_SPITFT.cpp#L240-L246

Fixed in v1.1.1. Thanks.
