Build fails with Arduinoand esp32s3 on Ubuntu Device

[ZanzyTHEbar]

Hello,

Fantastic. I normally program on Windows, and have not had an issue yet with your library.

However, i recently setup CI for a new project/client - using this lib for the HID application and i ran into an issue.

 In file included from .pio/libdeps/esp32s3_fancy_display/esp32-usb-v2/src/usb_keyboard.hpp:3,
                   from lib/FancyDisplay/src/io/usb/local_keyboard.hpp:5,
                   from src/main.cpp:6:
  .pio/libdeps/esp32s3_fancy_display/esp32-usb-v2/src/usb_hid.hpp:86:102: error: 'void tud_hid_report_complete_cb(uint8_t, const uint8_t*, uint8_t)' should have been declared inside '::'
           friend void ::tud_hid_report_complete_cb(uint8_t instance, uint8_t const* report, uint8_t len);
                                                                                                        ^

This error only occurs within the github action runner. On my home machine (windows 10) the project builds and runs perfectly fine.

Hi,
to be honest, i have no idea why you see this error (im not advanced C++ programmer) and i know nothing about github actions.
It is also possible this function definition changed or you are missing tinyusb library in your github actions.

Hi

I have the same error with ESP32-S2. Did you fix the error? @ZanzyTHEbar

[ZanzyTHEbar]

I have not fixed the error - how did the error arise for you? Are you on a native Linux distro?

[ZanzyTHEbar]

So,, i recently installed windows 11 - not this exact same issue happens on my windows 11 machine. So i can confirm without a doubt that the issue is not OS related. It's somehow related to the compiler.

I don't have my window10 install where this worked anymore, so no idea what compiler i had.

Update- i was able to get it to compile by commenting out

friend void ::tud_hid_set_report_cb(uint8_t instance, uint8_t report_id, hid_report_type_t report_type, uint8_t const *buffer, uint16_t bufsize);
friend void ::tud_hid_report_complete_cb(uint8_t instance, uint8_t const* report, uint8_t len);

And, then making these two function public:

virtual void _onSetReport(uint8_t report_id,
                              uint8_t const* buffer,
                              uint16_t bufsize) {}  // TODO
virtual void _onSendComplete(uint8_t const* buffer, uint16_t bufsize) {}  // TODO
