Any help would be more than welcome, as I'm a newbie with all these tools.

Hi,

Have you seen installed SDL?

[Joaquin500]

Hi,

The only place I see SDL2 is in C:\msys64\mingw64\include\SDL2.

NOTE: In the installation process I have skiped the step "https://github.com/lvgl/lv_platformio?tab=readme-ov-file#install-sdl-drivers" because it seems to be for Linux, and I'm using Windows. Anyway, my Terminal doesn't recognize the "sudo" command.

This guide can be helpful to install SDL on Windows: https://lazyfoo.net/tutorials/SDL/01_hello_SDL/windows/index.php

Thank you for your help and interest kisvegabor. I have followed the guide and installed SDL (which I think I had already did with MYS32). Then I changed the build_flag -D SDL_INCLUDE_PATH in platformio.ini to -D SDL_INCLUDE_PATH=""C:\vclib\SDL2-2.30.0\include\SDL.h"", and now it finds the elusive SDL.h

But, now I get the following error:

Linking .pio\build\emulator_64bits\program.exe
C:/msys64/ucrt64/bin/../lib/gcc/x86_64-w64-mingw32/13.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lSDL2: No such file or directory
collect2.exe: error: ld returned 1 exit status
*** [.pio\build\emulator_64bits\program.exe] Error 1

Well, obviously this task is far beyond my level, so I'm giving up with it. Again, thank you very much for your efforts trying to solve my issues.

It indicates that SDL2 is not installed or not seen by PlatformIO.

[Joaquin500]

I have it installed in 2 different places and both paths added to the PATH enviroment variable as indicated. Any way, I have given up and cleaned it all. Once again, thank you for your advice :-)

I'm sorry that we couldn't figure it out 🙁

Hello !

I ran into the same issue.
I have several toolchains installed.

As this repo uses mingw-w64-x86_64-gcc for which SDL2 is installed, you need to ensure you do compile with this Toolchain.

==> When you open the project in vscode / platformIo extension, it creates a .vscode/c_cpp_properties.json. You need to ensure you have this value:
"compilerPath": "C:/msys64/mingw64/bin/gcc.exe",

Thank you for your feedback. As I said in my last post, I have given up with this, but I'm sure that your post will be useful for other users that run into the same problem.

[lgrosbois-AtlasLaser]

No problem.
My post was mainly to store somewhere the resolution of the issue I had.
First developer reflex is to google the error, so finding a hint to resolution is always a good sign :)

Have a good day 👍
