TouchGfx with ILI9341

[zain_stm32]

Hi All,

This is the first time I am posting on this forum. I am new to cubeIde/cubeMX world.

 I have recently started integrating the touchGFX capability to my stm32 boards. I followed some online tutorials and youtube videos like these:

(https://www.youtube.com/watch?v=g1siKaPox88&list=PL6Fwy7aR3zSlZO3OBppHSzDacE4CGgRqO)

However I am having issues in compiling my code. The moment I compile my code I get like 200+ errors in  middleware and touchgfx/generate folder. I have tried creating a project using different boards however I am keep getting these errors.  I have tried configuring the board in cubeMx and then importing it in cubeIde, also tried creating  a project in just cubeide as well but i am keep getting these issues.

My cubeMx version is: 6.12.0

CubeIde version: Version: 1.16.0

TouchGfx version: 4.23.2

 

I have B-l475e-iot01a2(discovery board) and STM32L073RZ board. Problem is not the board here I tried creating a project using different board but my program is not compiling hence flashing the code to the board is the next step.

 

Please let me know what I am doing wrong. Any help will be much appreciated. I have attached screenshots of the errors I am getting. Please let me know if you guys need any further information.

Thanks for your response, The link which you shared helped me to understand that the first error matters the most but I am not sure how to resolve the first error and what is causing this problem. please have a look on my first 5 errors:

Those are linker errors.

They suggest that you are missing some source files and/or libraries.
