memcpy_P conflict with Arduino libraries

[n9wxu]

The library is sensitive to the include sequence.

The following two errors are creating a problem with compiling on [email protected]

.platformio\packages\framework-arduinoststm32\cores\arduino/avr/pgmspace.h:48: warning: "memcpy_P" redefined
48 | #define memcpy_P(dest, src, num) memcpy((dest), (src), (num))
|
In file included from .pio\libdeps\nucleo_l073rz\Crypto_ID1168\RNG.cpp:27:
.pio\libdeps\nucleo_l073rz\Crypto_ID1168\utility/ProgMemUtil.h:49: note: this is the location of the previous definition
49 | #define memcpy_P(d,s,l) memcpy((d), (s), (l))
|

I added a #undef in my header file that uses the crypto to remove the memcpy_P after the use of crypto is complete.

More information:

My "fix" does not fix anything. the real problem is found in RNG.cpp

The code below comes from line 23-31 of RNG.cpp.
The ProgMemUtil.h brings in an instance of memcpy_P and Arduino.h overrides it creating a conflict.

#include "RNG.h"
#include "NoiseSource.h"
#include "ChaCha.h"
#include "Crypto.h"
#include "utility/ProgMemUtil.h"
#include <Arduino.h>
#if defined (__arm__) && defined (__SAM3X8E__)
// The Arduino Due does not have any EEPROM natively on the main chip.
// However, it does have a TRNG and flash memory.
