src/buffer/FrameBuffer.cpp:8:88: error: 'std::string' has not been declared

Hi, got this error while compiling apparently according to this : https://stackoverflow.com/questions/17040098/c-stdstring-has-not-been-declared-error , this is not best practice . i know nothing about C/C++ programming so im not judging that. th workaround mentionned was working : #include in framebuffer.h

(FYI i m trying to compile for another esp32 board.) (atom M5stack).

Yes, true, there is indeed an include missing. As far as I know It depends on the compiler and the order of the files being compiled, if such errors will come up or not during compile time. I will add the include for correctness, even if my build currently is not broken. Thanks for bringing it up :+1:

But since this is a personal project, I will just support the platformio build for the Arduino ESP32, which is also tested by the github actions pipeline. If you're building for another esp32 board which does not have the arduino framework, it will take some time to port the code. I actually outlined the process of porting this project to another board (without arduino) here: https://github.com/tspopp/AquaMQTT/issues/28#issuecomment-2211764088

Hi, thanks for answer, im actually compiling with this in the platformio.ini :

`[env:arduino_nano_esp32]
platform = espressif32
board = m5stack-atom
framework = arduino
test_framework = googletest
build_flags = -std=c++11
# uncomment the below lines to use over the air update
#upload_protocol = espota
#upload_port = 192.168.188.62
lib_deps =
    locoduino/RingBuffer
    FrankBoesing/FastCRC
    PaulStoffregen/Time
    256dpi/MQTT
    adafruit/Adafruit BusIO
    adafruit/RTClib
    Wire
    SPI`

so basically i just changed the board name (and altered the pin names for the RTC.) i got the same issue further in the code : src/task/MQTTTask.cpp: In static member function 'static void aquamqtt::MQTTTask::messageReceived(String&, String&)': src/task/MQTTTask.cpp: In static member function 'static void aquamqtt::MQTTTask::messageReceived(String&, String&)':

i find strange that having nearly the same.ini , this kind of error appears , i m unable to compile, i recloned the project this morning and tried to compile without any modif and got another error, ill make a new issue for this one.
