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)

Hello @OLync.1 ,
 

Have you tried to delete the Middleware folder and the Touchgfx/generated one ? Try to do that and regenerate afterward.

Regards,

[OLync.1]

I deleted the folders and regenerated them via CubeMX and TouchGfx but problem remains - appears to be in LCD16bpp code:

undefined reference to `touchgfx::paint::flushLine(unsigned long*, int)'

I just get 4 errors when it comes to this flushLine in CubeIDE folder:

C:\STM32CubeIDE_1.13.2\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.win32_1.0.100.202403111256\tools\bin

Have you found how to resolve it?

[unsigned_char_array]

Have you checked all the framework features checkboxes in TouchGFX (under Config)? Try checking all of those and regenerating code in TouchGFX.

[Enekkk]

I've checked all of them and the error just continues, i did not touch any framework before so.

[unsigned_char_array]

Have you checked the difference between the git commit before and after the migration? Try making a new project and using a diff tool such as diffmerge or winmerge to compare your project with it. Maybe you see a difference somewhere. If that is too much work try the same with a stripped version of your project.

[Enekkk]

I am working currenlty on touchGFX 4.23 with same code and no error appeared. I will continue using 4.23 for the moment. Thank you!

[OLync.1]

@LouisB I have updated the TouchGfx component in MX 6.11.1 to the latest and regenerated code:

Now I get the same as @Enekkk:

undefined reference to `touchgfx::paint::flushLine(unsigned long*, int)'
in function `touchgfx::LCD16bpp::DecompressorRGB_QOI::blitCopyRGB565(unsigned char const*, touchgfx::Rect const&, touchgfx::Rect const&, unsigned char)'

 It seems that TouchGfx 4.24 is not backward compatible with 4.23. Please advise on a solution as I want to use the 4.24 features. (Does MX need to be updated to support TouchGfx 4.24?)

[OLync.1 · Accepted solution]

I now have a successful build. I needed to manually import TouchGfx 4.24 zip into MX (Embedded Software Packages Manager -> From Local...) and then update the selection to 4.24 (Software Packs Component Selector) and then regenerate the code. Maybe this is documented somewhere but it's certainly not intuitive and hard to navigate when done infrequently.
