Hello solution is simple .
fixes in files with fonts (font_name.c in UTFT folder )"uint8_t" to "const char"
for example
original file
fixed file
fixes in files with fonts (font_name.c in UTFT folder )"uint8_t" to "const char"
for example
original file
// various_symbols.c
// Font type : Full (95 characters)
// Font size : 16x16 pixels
// Memory usage : 3044 bytes
// Submitted by : MBWK
#include <avr/pgmspace.h>
uint8_t various_symbols[3044] PROGMEM={fixed file
// various_symbols.c
// Font type : Full (95 characters)
// Font size : 16x16 pixels
// Memory usage : 3044 bytes
// Submitted by : MBWK
#include <avr/pgmspace.h>
/*uint8_t*/const char various_symbols[3044] PROGMEM={

Here you can download my Arduino IDE
iot-playground.com/swdownload/Arduino.zip
unzip it to your computer and try compile thermostat sketch with it

Now I got it! Thanks for your help here. I'm not sure if it will work correctly but I used the IDE you gave me and changed the font files similarly to what kindr suggested. I change "const uint8_t various_symbols[3044] PROGMEM={" and removed the const, it compiled then, but I don't know if they need to be constants. At least I can get it to load and run now..

And... I am lost.
I am working with Arduino 1.6.5
I assumed the .h files for the fonts do not exist and I added the contents of the fonts .c files to the .ino file.
I also made the change from "iunt8_t* const..." to "const char..." as indicated above.
However, when I compile, I get an error at every single instruction which uses any of the three fonts defined by the "const char...: instructions. The error reads as follows:
Invalid conversion from 'const char*' to unit8_t* {aka unsigned char*}' {-fpermissive}
Any idea what is going on ?
What am I missing ?
Thanks,

Originally code was compiled with Arduino IDE 1.0.6. There are some issues with Ardino 1.6.5 when you compile this code.
