I’m using VS Code on a Windows machine and trying to compile the GUIslice example the ex46_ard_togglebtn.ino example which compiled in fine in the Arduino IDE.
The error that happens is:
Compiling .pio\build\esp32dev\FrameworkArduino\Esp.cpp.o
.pio/libdeps/esp32dev/GUIslice/src/GUIslice_drv_tft_espi.cpp: In function 'bool gslc_DrvGetTxtSize(gslc_tsGui*, gslc_tsFont*, const char*, gslc_teTxtFlags, int16_t*, int16_t*, uint16_t*, uint16_t*)':
.pio/libdeps/esp32dev/GUIslice/src/GUIslice_drv_tft_espi.cpp:394:31: error: ISO C++ forbids declaration of 'type name' with no type [-fpermissive]
m_disp.setFreeFont((const GFXfont *)pFont->pvFont);
When I follow the trail to GUIslice_drv_tft_espi.cpp:394:31 VS Code tells me that GFXfont is undefined but it is defined in Adafruit-GFX-Library/gfxfont.h at master · adafruit/Adafruit-GFX-Library (github.com) which is included in Adafruit-GFX-Library/Adafruit_GFX.h at master · adafruit/Adafruit-GFX-Library (github.com)
My platformio.ini file has the following
[platformio]
;lib_dir = .
[env]
;lib_ldf_mode = chain+ ;i also tried deep
[env:esp32dev]
platform = espressif32
;platform = https://github.com/platformio/platform-espressif32.git ; will force to use the 2.0 board package
board = esp32dev
framework = arduino
lib_deps =
SPI
Wire
adafruit/Adafruit BusIO
adafruit/Adafruit GFX Library
impulseadventure/GUIslice
TFT_eSPI
adafruit/Adafruit FT6206 Library ; needed for GUIslice
build_flags =
-DUSER_CONFIG_LOADED
-DUSER_CONFIG_INC_FILE
-DUSER_CONFIG_INC_FNAME=\"../configs/esp-tftespi-default-ft6206.h\"
# Now TFT_eSPI Build Flags
So the Adafruit GFX Library is included but I can’t seem to find why it’s not found and as you can see I’ve tried a couple of different options in my platformio.ini file.
I could be wrong with the root cause of the compile error so I can provide more details if needed.
Unable to reproduce. Using your exact platformio.ini with this as src/main.cpp but with #include <Arduino.h> at the top produces

I didn’t change the name to main.cpp so it still shows as the ino file in the src directory so maybe that’s it?
You still have the original includes, right?
#include "GUIslice.h"
#include "GUIslice_drv.h"
Thanks for testing for me!
OK drilling down on the problem. I too can compile as long as I don’t have the TFT_eSPI build flags. Once I add these to my platformio.ini I’m back to the error. I started with a fresh workspace and just created a new project and copied and pasted the example code into main.cpp.

OK, just stumbled across that if I comment out

I can get it to compile. Since I still have the rest of my build flags I think I’m OK and things will work but I’m a bit confused on why I’m getting that compile error
