Thank you very much for the replies. I appreciate your support.
I am experiencing some strange behavior within the project window now. Yesterday I was able to set the "simulator" folder to be "Exclude resource from build". I know it took effect because the folder was grayed out in the project viewer.
Today when doing a build, I am getting the same error I was before:
===============================================
/Middlewares/ST/TouchGFX/touchgfx/framework/include/platform/hal/simulator/sdl2/HALSDL2.hpp:22:10: fatal error: SDL2/SDL_video.h: No such file or directory
===============================================
And when I looked at the simulator folder it is no longer grayed out, nor can I change it. In fact, there is a key icon above the folder in the viewer:
I tried to deselect "Exclude resource from build" and select it again, and am not able to exclude it any more. I will start over with a fresh project and see if that helps. But do you have any ideas in the meantime why the folder now appears to be locked from excluding it?
Update: I just noticed that you stated up above that even though the tool can indicate that it not excluded it actually is, so maybe you already answered this question.
Martin,
I tried an experiment to see if I can get your example to do this same thing. I assume your configuration is correct and wanted to see if I can make it fail when going through these steps. I created a new workspace and imported your example project (f746g-disco-test). I was able to successfully import the project and debug it (via Run > Debug Configurations > STM32 MCU Debugging > f746g-disco-test.elf). My Discovery board loaded up with your code of a red and green screen, each with a button on it causing it to switch between screens.
Because I need to utilize more quad SPI flash, I opened up CubeMX by double-clicking the file "f746g-disco-test.ioc" and set the QUADSPI configuration as the following link describes:
https://touchgfx.zendesk.com/hc/en-us/articles/360019884752-Configuring-STM32F746G-DISCO
Then I attempted to run the debugger again and I got the following fatal error on the build:
===============================
/Middlewares/ST/TouchGFX/touchgfx/framework/include/platform/hal/simulator/sdl2/HALSDL2.hpp:22:10: fatal error: SDL2/SDL_video.h: No such file or directory
===============================
When I checked the simulator directory it was selected to "Exclude resource from build", but I could no longer set it to be excluded from the build.
I set the quad spi flash to the previous settings but this did not resolve the issue.
It appears that whenever the configuration is edited, something in the project files changes to cause this. I differenced the files and found a number of things that had been changed. I copied them from your original project to my project and still had an issue. There was a missing file called OSWrappers_cmsis.cpp (located Middlewares/ST/TouchGFX/touchgfx/os) . Once I copied that file from your project to my project, the code compiled.
I copied the previous project files back over into my project and it worked fine, so I do suspect something is being messed up when the CubeMX is edited.
In fact, I do not believe that the configuration file needs to be edited to cause this issue. I created a new project based on your example. Opened the configurator by double-clicking the file "f746g-disco-test.ioc" then doing a CubeMX "generate" without making any changes. After this point, the project will not build and I am not able to exclude the simulator directory ( i get the fatal error on SDL_video.h).
