TouchGfx 4.24 linker problem

[OLync.1]

I have just upgraded my project from TouchGfx 4.22 and on rebuild I get:

I followed advice elsewhere and regenerated code from CubeMX before regenerating from TouchGfx designer, with same result.

For this error:

undefined reference to `touchgfx::paint::rgb565::lineFromRGB565(unsigned short*, unsigned short const*, unsigned int, unsigned char) 

There is an implementation in PaintRGB565Impl.hpp:

void lineFromRGB565(uint16_t* const ptr, const uint16_t* const data, const unsigned count, const uint8_t alpha)

CubeMX v6.11.1

TouchGfx: v4.24.0

CubeIDE: v1.15.1 Build: 21094_20240412_1041 (UTC)

The regenerate code has to be done even on a new project so I don't think it's intentional.

I have exacted the same problem as you have and the same feeling.

[MMüll.6]

How it works with my environment:

- Update CubeMx to V6.11.1 (including the HAL firmware files where you have installed)
- Update CubeIDE to V2.15.1
- Update TouchGFX with CubeMx V4.24.0
- Install TouchGFX V4.24.0
- Open in the CubeIDE the IOC file, it update to the new HAL, save.
- Open the touchgfx project von V4.24.0 and generate the code
- CubeIDE menu Project >> Clean...
- CubeIDE, open the ioc file again
- CubeIDE menu Project >> Generate Code
- CubeIDE menu Project >> Build All

After this steps, no errors in the console output (same as befor update).
The step "Project >> Generate Code" fix the issue, I hope it help.
