Problem with TFT_eFEX on latest version of espressif32 arduino framework dependancy

[renegadeandy]

I am using a ESP32-WROOM-32 with GuiSlice and the TFT_eFEX and TFT_eSPI successfully. For various reasons I changed my platform code to use : https://github.com/pioarduino/platform-espressif32/releases/download/stable/platform-espressif32.zip which I believe is newer than I originally used.

Since doing this, when I compile my application it fails with:

.pio/libdeps/esp32dev/TFT_eFEX/TFT_eFEX.cpp: In function 'bool jpgDecode(jpg_file_decoder_t*, uint32_t (*)(JDEC*, uint8_t*, uint32_t))':

I read about a similar issue which didn't seem to get resolved on the TFT_eFEX repo here:Bodmer/TFT_eFEX#44

I decided to just comment out those declarations from the library and then I hit GUISlice issues as it dependended on these jpg functions:

toolchain-xtensa-esp-elf/bin/../lib/gcc/xtensa-esp-elf/14.2.0/../../../../xtensa-esp-elf/bin/ld.exe: .pio/build/esp32dev/lib9f7/GUIslice-0.17.2/GUIslice_drv_tft_espi.cpp.o:(.literal.gslc_DrvDrawJpegFromFile+0x4): undefined reference to TFT_eFEX::drawJpgFile(fs::FS&, char const*, unsigned short, unsigned short, unsigned short, unsigned short, unsigned short, unsigned short, jpeg_div_t)' toolchain-xtensa-esp-elf/bin/../lib/gcc/xtensa-esp-elf/14.2.0/../../../../xtensa-esp-elf/bin/ld.exe: .pio/build/esp32dev/lib9f7/GUIslice-0.17.2/GUIslice_drv_tft_espi.cpp.o: in function gslc_DrvDrawJpegFromFile':
.pio/libdeps/esp32dev/GUIslice-0.17.2/src/GUIslice_drv_tft_espi.cpp:1080:(.text.gslc_DrvDrawJpegFromFile+0x22): undefined reference to `TFT_eFEX::drawJpgFile(fs::FS&, char const*, unsigned short, unsigned short, unsigned short, unsigned short, unsigned short, unsigned short, jpeg_div_t)

I am using an image element in GUISlice : gslc_ElemCreateImg, to display a bitmap.

Can you help:
1/Get my project compiling again
2/The challenge we now have with the TFT_eFEX compatibility?

@renegadeandy Well, thats the problem with using libs written by other people.
Over time code ages and stops working.

If you don't need Jpeg support why not just comment out line 1080 in GUIslice_drv_tft_espi.cpp?
I can't support TFT_eFEX myself after all. Guislice may need to find another library to replace it...

Commenting out the if ESP32 block including the call to the function does indeed resolve the issue. However I am not keen on the solution as it will break each time I upgrade GUISlice and creates a bit of a dependency nightmare!

Of course I don't expect you to support TFT_eFEX yourself! We, the community, should if possible look to find an alternative, or perhaps bring TFT_eFEX up to date....
