Error compiling in an ESP32. This happened after you upgraded the ESP32 module SDK. Can someone help me with this please?

 

[Erel]

Try this, edit rCore.h, located in the internal libraries folder and comment line #18:

//extern void *operator new( size_t size, void *ptr );

 

[Johan Hormaza]

Thanks @Erel, it works great.
By the way, why this operator "extern void * new (size_t size, void * ptr);" there?

 

[Erel]

It is needed in most cases.
