I want to use ESP32 for my app. When I compile this code with PlatformIO I get the following error:
[env:nodemcuv2]
platform = https://github.com/Jason2866/platform-espressif32.git#feature/arduino-idf-v4.4
board = nodemcu-32s
framework = arduino
monitor_speed = 115200
I get this Error:
|-- <ESP32 BLE Arduino> 2.0.0
Building in release mode
Linking .pio/build/nodemcuv2/firmware.elf
/Users/juliusschmid/.platformio/packages/toolchain-xtensa32/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld: final link failed: bad value
collect2: error: ld returned 1 exit status

I don't understand why I get this error message. Can someone help me and explain easily how I can fix the error?
I am trying to build the protobuf compiler for MATLAB using github.com/BraunPhilipp/protobuf-matlab (forked from farsounders code). I followed the instructions at the site and I keep getting this error:

Any help would be great
I am getting a linker error when trying to build redis-stable (should be 5.0.5) on raspbian buster running on the latest Raspberry Pi 4
make goes through the motions and then fails with the following
LINK redis-server
/usr/bin/ld: networking.o: in function `createClient':
/home/pi/redis-stable/src/networking.c:109: undefined reference to `__atomic_fetch_add_8'
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:219: redis-server] Error 1
make[1]: Leaving directory '/home/pi/redis-stable/src'
make: *** [Makefile:6: all] Error 2
Am I missing a setting somewhere?
I was able to get all the tests to run successfully by adding the compiler flag -latomic only to the redis-server
# redis-server
$(REDIS_SERVER_NAME): $(REDIS_SERVER_OBJ)
$(REDIS_LD) -o $# $^ ../deps/hiredis/libhiredis.a ../deps/lua/src/liblua.a $(FINAL_LIBS) -latomic
EDIT: This is with Redis 5.0.5
I was able to run by adding the compiler flag -latomic only to the haproxy

I have compiled and installed alsa-lib 1.1.0 and moved on to compiling and installing the new alsa-util. The ./configure works:
./configure --disable-bat --disable-xmlto --disable-alsaconf --with-curses=ncursesw
however the make fails and I have had no luck finding a resolution:

I understand that this error means that undefined references exist but I cannot understand why?
Thanks.
