libtouchgfx-float-abi-hard.a cause build error in STM32CubeIDE

I followed instrunction in this online workshop STM32 Graphics Workshop - 10 TouchGFX lab temperature sensor display https://www.youtube.com/watch?v=rYrRjXyAYvs&list=PLnMKNibPkDnGNY9Ny4FWpM5bgC3b4XdbN&index=10

When I get to (minute 18:30) the step build in STM32CubeIDE I get this error list below. Please help.

Hi,

I wont lie that it is a bit complicated to read that text :grinning_face_with_sweat:. Could you maybe share your project or add a screenshot of this error message ? (the colors will help us see faster where the issues are).

I have not gone through that video but I suppose you followed all the steps ?

The online training its starter files are based on TouchGFX 4.13. The generated Texts.cpp has a different format and methods from what the TouchGFX 4.14 generate. I uninstalled the version 4.14 and installed the version 4.13 and the labs work as expected. Enclosed are the 2 Texts.cpp files generated. You find this file under C:\TouchGFXProjects\STM32H7BWorkshop_lab4\TouchGFX\generated\texts\src

The errors caused by the four extra methods generated by the GFX Version 4.14

Enclosed is the full project for GFX version 4.13 (26.4 MB) This is the working version with lab4 completed.

Enclosed is the full project for GFX version 4.14 up to the point after ToughGFX generated the code and STM32CubeIDE compile error. (40 MB) I am not sure why the compress files is so much larger for version 4.14.

Hi Romain,

With respect to the problem I discovered and described previously, I think the TouchGFX 4.14.0 code generation for Texts.cpp file has problem. Will the TouchGFX team look into this issue and confirm my thoughts.

Hi Stran.2,

did you solve the issue?

I have the same problem

Hi FMarr

I down grade to ToughGFX 4.13 then it works as I show in the previous attachment. An ST employee has the suggested solution to use latest TouchGFX version here: STM32 Graphics Workshop - TouchGFX fail to run Target STM32H7B3I_DISCO

I have not try it yet but I will in a few weeks when I get back to working on STM project again. If you try the solution, please post if you have more information about it.
