I am frustrated with this error that has got me stuck for approx 3 days till now. I am trying to setup esp32 audio framework for the ESP32 audio kit by AI-thinker. c:/users/admin/.espressif/tools/xtensa-esp32-elf/esp-2020r3-8.4.0/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: C:/esp/ESP32-A1S-AudioKit/components/esp-sr/liblibmultinet.a(multinet1_quantized_cn.o):(.literal.lvcsr_reset+0x0): undefined reference to `sr_rb_reset’ c:/users/admin/.espressif/tools/xtensa-esp32-elf/esp-2020r3-8.4.0/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: C:/esp/ESP32-A1S-AudioKit/components/esp-sr/liblibmultinet.a(multinet1_quantized_cn.o):(.literal.lvcsr_model_run_accelerate+0x18): undefined reference to `sr_rb_read’ c:/users/admin/.espressif/tools/xtensa-esp32-elf/esp-2020r3-8.4.0/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: C:/esp/ESP32-A1S-AudioKit/components/esp-sr/liblibmultinet.a(multinet1_quantized_cn.o):(.literal.lvcsr_model_run_accelerate+0x1c): undefined reference to `dl_convq_queue_push_by_qmf’ c:/users/admin/.espressif/tools/xtensa-esp32-elf/esp-2020r3-8.4.0/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: C:/esp/ESP32-A1S-AudioKit/components/esp-sr/liblibmultinet.a(multinet1_quantized_cn.o):(.literal.lvcsr_model_run_accelerate+0x20): undefined reference to ..

I have following classes: class ATemperatureDevice{}; class AHumidityDevice{}; class BluetoothLeDevice{}; class Sensor1 : BluetoothLeDevice, ATemperatureDevice, AHumidityDevice {}; class Sensor2 : BluetoothLeDevice, AHumidityDevice {}; I have a vector<BluetoothLeDevice>, where all devices are stored. The Classes ATemperatureDevice, AHumidityDevice and BluetoothLeDevice have virtual functions. When I pick one, I have a BluetoothLeDevice. Now I want to check if ..

This is a program for using fonts in MCUs. I have 4 files. ‘zar.h’ and ‘zar.cpp’ contains data of one font. ‘font.h’ and ‘font.cpp’ contains pointers and functions for set fonts dynamically. There is a lot of problems with pointers. When access elements of "XB_Zar_name" array, by "uni_name[i]" pointer, MCU dos reset’s. Another problem is ..
