BME680 BSEC Arduino Uno compile error

[skumar]

I am trying to compile to BSEC basic for arduino uno platform. I modified the platform.txt as indicated here :https://github.com/BoschSensortec/BSEC-Arduino-library. I created a atmega328p folder in src directory and copied the lib.

now i get the error: 

/Applications/Arduino.app/Contents/Java/hardware/tools/avr/bin/../lib/gcc/avr/5.4.0/../../../../avr/bin/ld: skipping incompatible /Users/skumar/Documents/Arduino/libraries/BSEC-Arduino-library-master/src/atmega328p/libalgobsec.a when searching for -lalgobsec
/Applications/Arduino.app/Contents/Java/hardware/tools/avr/bin/../lib/gcc/avr/5.4.0/../../../../avr/bin/ld: cannot find -lalgobsec

collect2: error: ld returned 1 exit status

Modified the platform.txt to include compiler.libraries.ldflags.

recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}" {compiler.c.elf.flags} -mmcu={build.mcu} {compiler.c.elf.extra_flags} -o "{build.path}/{build.project_name}.elf" {object_files} {compiler.libraries.ldflags} "{build.path}/{archive_file}" "-L{build.path}" -lm

I am using this on MAC, installed the latest arduino uno (1.8.9).

I understand the library libalgobsec.a is part of the megaAVR family which includes atmega series, which means it should work for atmega328p or uno platform.

Any suggestions on how to fix this?.

I downloaded this repo today (25.9.2020) and tried to compile basic sketch for ATmega2560 but got the similar (incompatible) error:

c:/program files (x86)/arduino/hardware/tools/avr/bin/../lib/gcc/avr/7.3.0/../../../../avr/bin/ld.exe: skipping incompatible C:\Users\arduinouser\Documents\Arduino\libraries\BSEC\src\atmega2560\libalgobsec.a when searching for -lalgobsec
