[BUG] MarlinSimulator Crashes in Windows

[classicrocker883]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

I get an error strlcpy undefined.
in ini/native.ini -DHAS_LIBBSD makes it so strlcpy is not defined because of the #ifndef HAS_LIBBSD directive. I dont know if this was a mistake and should be #ifdef instead, but removing -DHAS_LIBBSD solves that issue.

however, the "SDL2" library is in 'Program Files' and not '**C:**', at least thats how it defaulted in my installation. but I did notice to install now it goes to C: for new installs for MSYS2 mingw64

I was able to circumvent this by copying the SDL2 directory into libdeps/simulator_windows/, or change it to "Program\ FIles" in the .ini

anyway I dont know but I used to be able to get the MarlinSimulator.exe running just fine, I have an older version of this that doesn't crash. but anytime I make a new one, it will load, and subsequently crash after like 3 seconds of being open. it actually closes instead of crashing.

Bug Timeline

Use strlcpy with buffer size (#26513)

Expected behavior

MarlinSimulator_Working.zip

Actual behavior

MarlinSimulator_Crashes-pt1.zip
MarlinSimulator_Crashes-pt2.zip

(extract -pt2 first)

Steps to Reproduce

1. Take a Config example, like CrealityUI for Ender3-V2
2. I used DWIN_LCD_PROUI
3. To create your own MarlinSimulator, start by changing in Configuration.h MOTHERBOARD to BOARD_SIMULATED, also disable ENDSTOP_INTERRUPTS_FEATURE
4. In platformio.ini default_envs = change to simulator_windows.

There is no simulation for a DWIN_LCD_PROUI (or any other dwin displays in the simulator)
Best you would get is a raw serial data

Here's the simulator config: https://github.com/MarlinFirmware/Configurations/tree/bugfix-2.1.x/config/examples/Simulator

//
// Simulator currently supports these displays. Choose one!
//
#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
//#define REPRAP_DISCOUNT_SMART_CONTROLLER
//#define TFT_CLASSIC_UI
//#define TFT_COLOR_UI

// Enable parent LCD based on your selection above
#if ANY(TFT_CLASSIC_UI, TFT_COLOR_UI)
  #define TFT_GENERIC
  #define TOUCH_SCREEN
#elif ENABLED(LIGHTWEIGHT_UI)
  #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
#endif

-DHAS_LIBBSD is set on environments where strlcpy is already part of the OS so the code doesn't need the work around in the #ifndef HAS_LIBBSD block

bridging sim to real serial port is possible with socat, port 3 is TCP socket on port 8099

@ellensp by default in my MSYS2 installation of Windows 10 x64 libbsd seems to be missing, I added it to MSYS2 by executing:

$ pacman -S libbsd

The package was installed but VSCODE still cannot find strlcpy (I also tried with -lbsd).

By removing -DHAS_LIBBSD from the simulator_windows environment in native.ini your implementation is used and the simulator can be compiled and all is working correctly.
