error: 'OSWrappers' has not been declared

[lsoon]

Hi everyone,

STM32CubeIDE 1.3.0

32F746-Dicovery

In the above environment, I chose TouchGFX as an additional software and added graphics.

And I created a simple GUI for testing by opening the file in the created TouchGFX directory.

And when compiling, the following error appeared.

../TouchGFX/target/generated/TouchGFXGeneratedHAL.cpp:35:32: error: 'OSWrappers' has not been declared

   registerTaskDelayFunction(&OSWrappers::taskDelay);

                ^~~~~~~~~~

make: *** [TouchGFX/target/generated/subdir.mk:28: TouchGFX/target/generated/TouchGFXGeneratedHAL.o] Error 1

make: *** Waiting for unfinished jobs....

​Is there any way to solve it?

Thank you.

Finished my tests. .ioc file definitely says STM32CubeIDE as expected - Great!

ProjectManager.PreviousToolchain=
ProjectManager.ProjectBuild=false
ProjectManager.ProjectFileName=746gtest.ioc
ProjectManager.ProjectName=746gtest
ProjectManager.StackSize=0x400
ProjectManager.TargetToolchain=STM32CubeIDE
ProjectManager.ToolChainLocation=
ProjectManager.UnderRoot=true
ProjectManager.functionlistsort=

• Add TouchGFX from Additional Software in CubeMX and generate code. Failures in compilation due to missing TouchGFX bootstrap.
• Open the .part file in TouchGFX designer and generate code. Here's part of what happened to the .cproject file (include paths).

Compiling OSWrappers.cpp without issues - Remember to press F5 on your CubeIDE project to reload changes to .cproject file! Classic eclipse. Once you do, TouchGFX will appear in the "Middlewares" folder.

make -j8 all 
arm-none-eabi-g++ "../TouchGFX/target/generated/OSWrappers.cpp" -mcpu=cortex-m7 -std=gnu++14 -g3 ....
arm-none-eabi-g++ "../TouchGFX/target/generated/TouchGFXConfiguration.cpp" -mcpu=cortex-m7 -std=gnu++14 ...
arm-none-eabi-g++ "../TouchGFX/target/generated/TouchGFXGeneratedHAL.cpp" -
...

And finally we're done:

 Going to bed so i won't see answers until tomorrow. Good night! 😉
