Description:
Gives base64.h:8:12: error: 'String' does not name a type and base64.h:9:26: error: 'uint8_t' has not been declared when called the static String base64::encode(uint8_t * data, size_t length) function.

Including arduino.h or WString.h and stdint.h on base64.h fix the error.

Can you give sample code? This works for me:

#include <base64.h>
base64 test;
void setup() {
  test.encode("Blahblahblah");
}
void loop() {}

@lbernstone : Could please check the below library and its example which I created.

You can put the required headers at the top of your library. While it would be nice to have everything in the codebase work standalone, it is generally assumed that you will be running as part of an arduino app.

I have tested the code with WString.h and stdint.h included on the ESP32AESB64.h but still gives the same error.

[lbernstone]

It works fine for me when I include those. Are you including them before the library that requires them?

[Jeard]

Adding modified version of base64.h and base64.cpp to src folder of library fixed the issue.

@Jeard update the link for the modified version of base64.h and base64.cpp files
