Compilation error when adding AESLib to Platformio project (ESP32-Arduino framework)

[mrdc]

Hello,

I'm having a compilation issue when I add AESLib to my project in Platformio:

Compiling .pio\build\esp32doit-devkit-v1\lib76b\AESLib\base64.cpp.o
Compiling .pio\build\esp32doit-devkit-v1\lib1e2\HTTPClient\HTTPClient.cpp.o

Looks like there is a conflict because of custom base64 lib which AESLib uses and base64 lib in ESP32-Arduino.

Interesting. I'm seeing the same issue, but am not sure this has anything to do with AESLib. Maybe some namespace collision?

Can be solved by commenting-out the _base64Authorization = base64::encode(auth); line in HTTPClient.cpp, if base64 authorization is not used.

Otherwise needs to be examined (AESLib does use own base64 implementation instead of the one in core, it will probably have to be renamed first, later reused the system one).

Yes, I’ve also tried to rename it - compilation failed (it was some time ago - don’t remember exactly the error).

Try this branch https://github.com/suculent/thinx-aes-lib/tree/base64-fix – if this won't help, it's not caused by AESLib, but can be still overridden by commenting out the line from post above.

BTW, I've found out that my project with same error as yours does not include AESLib at all... i've downgraded to 2.5.0, upgraded back to 2.6.2 and the error is not there. So I need confirmation, whether it's the AESLib or not.

Thanks, it works! Strange that It hasn’t compiled when I had renamed it.
