Compilation problem, SOS_IIR_Filter

[elbozzal]

Hello,
This work looks incredible, but I struggle at compilation time. IDE (Arduino IDE 2.3.2), board ESP32 DEV KIT.
When I compile, sos_iir_filter.h fails with this error.
micro_inmp441.ino.ino:140:1: error: designated initializers cannot be used with a non-aggregate type 'SOS_IIR_Filter'
140 | };
I checked, looks like other had this issue, but could not find the answer anywhere.

For those whom the project work, do you have any clue? Is there a library I miss (only .h no .cpp) or something like that?

Thanks in advance

Same issue on ESP32-C6 using latest Arduino IDE with ESP32 extensions

Same problem here. Solved by installing a toolchain dated about 2019 f.i. 1.0.5 espressif ESP32.
