Error "Run Simulator"

[TechnicalPBG2025]

Hello,

I'm working on a project in the TouchGFX Designer environment and when I try to execute the "Run Simulator" command, this error occurs.

How can I solve this problem?

[nico23]

I had a similar error on SDL2 compilation. Sometimes it messes up during compilation/build and returns this error.

I usually fix cleaning up the build folder in TouchGFX and then rebuild the whole project within TouchGFX

Hello @TechnicalPBG2025 ,

When you add code or logs to your post, I invite you to use the "Insert code" button to keep everything clean.
I have modified your previous post to properly insert code.

I am not sure what is causing the issue, your TouchGFX should be able to find the SDL files.

Does it happens on every project you create or just this one?

Can you share your full project?

Did you do something special to your computer?

Hi @GaetanGodart,

I managed to solve the problem of the SDL2.dll and SDL2_image.dll libraries, I saw that they were missing in my project.

I only have this problem in this project.

Now I tried to relaunch the simulation but it generates another error:

Hello @TechnicalPBG2025 ,

I don't really know what the issue is here, we should look at what is in line 160 and 155 but also it looks like it is the wrong SDL file.

However, I think the simplest way to fix your project here is to create a new one and to import your GUI from the current project by selecting Edit => Import => GUI.

Hello @TechnicalPBG2025 ,

Have you been able to move forward on your project?
