I’ve been trying to get the STM32duino Low Power library to compile, but I get a long string of errors relating to the RTC library such as:
.pio\libdeps\bluepill_f103c8\STM32duino RTC\src\STM32RTC.cpp: In member function 'void STM32RTC::sy ncAlarmTime()': .pio\libdeps\bluepill_f103c8\STM32duino RTC\src\STM32RTC.cpp:988:5: error: 'hourAM_PM_t' was not de clared in this scope 988 | hourAM_PM_t p = HOUR_AM; | ^~~~~~~~~~~ .pio\libdeps\bluepill_f103c8\STM32duino RTC\src\STM32RTC.cpp:991:38: error: 'p' was not declared in this scope 991 | &_alarmSubSeconds, &p, &match); | ^ .pio\libdeps\bluepill_f103c8\STM32duino RTC\src\STM32RTC.cpp:990:5: error: 'RTC_GetAlarm' was not d eclared in this scope; did you mean 'HAL_RTC_GetAlarm'? 990 | RTC_GetAlarm(&_alarmDay, &_alarmHours, &_alarmMinutes, &_alarmSeconds, | ^~~~~~~~~~~~ | HAL_RTC_GetAlarm .pio\libdeps\bluepill_f103c8\STM32duino RTC\src\STM32RTC.cpp:992:26: error: 'HOUR_AM' was not decla red in this scope; did you mean 'HOUR_12'? 992 | _alarmPeriod = (p == HOUR_AM) ?

I think it’s the same as this issue because the RTC library is a dependency of the low power module. However, I can’t figure out how to get it working.
I’ve tried including the RTC library in the list of lib_deps separately using the GitHub link in the above forum posts, I’ve tried downgrading to version 13 of the ststm32 platform and I’ve been using
pio system prune -f and deleting .pio throughout but nothing has had any effect.
Here’s the minimum platformio.ini file that causes the build to fail:
[env:bluepill_f103c8] platform = ststm32 board = bluepill_f103c8 upload_protocol = serial framework = arduino lib_deps = stm32duino/STM32duino Low Power @ 1.0.3
Does anyone have any ideas how I could get it working?
