esp32: conflict with <SdFat.h>

[bvsall]

I am trying to make WiFi SD for 3D Printer on ESP32 using your ESPWebDAV library.
For SD I use <SdFat.h> because I think it's faster.
If i connect (uncomment) your library, an error occurs during compilation.
I'm not very good at C. Can you tell me what i can do?
To make it easier to understand, I removed everything unnecessary from the program.

======================================================================================
#include <ESPWebDAV.h>
#include <SdFat.h>
SdFat SD;
File myFile;

void setup() {

if (!SD.begin(5, SD_SCK_MHZ(20))) {
Serial.println("initialization failed!");
return;
}
Serial.println("initialization done.");

// open the file.
myFile = SD.open("test.txt", O_RDONLY);

myFile.close();
}
void loop() {
// nothing happens after setup
}

=======================================================================================

The SDFat API is not same as ESP32 SD API - so it won't work by just changing the SD reference

You need to virtualize SDFat to use same FS API as ESP32 SD . typicaly File of SDFat is not same File of ESP32

try the original SDMMC directory, I tested it on esp32cam
...
//#include <SPIFFS.h>
//#include <LITTLEFS.h> //pipi
#include <SD_MMC.h>
...
//FS& gfs = LITTLEFS;
//#define FILESYSTEM LITTLEFS
//#define FILESYSTEM SPIFFS
FS& gfs = SD_MMC;
#define FILESYSTEM SD_MMC
