BSEC Compilation Error on MEGA 2560 with Arduino IDE

[anelephantheart]

Hi, 

I'm trying to use BSEC library on Arduino Mega 2560. Although I'm using the guide on BSEC Github Page for Arduino Library, somehow I cannot compile the "Basic" code on Examples. 

Ide: Arduino Ide 1.8.9

Platform txt(C:\Users\yalci\Desktop\arduino-1.8.9-windows\arduino-1.8.9\hardware\arduino\avr\platform.txt):

...
# These can be overridden in platform.local.txt

compiler.c.extra_flags=
compiler.c.elf.extra_flags=
#compiler.c.elf.extra_flags=-v
compiler.cpp.extra_flags=
compiler.S.extra_flags=
compiler.ar.extra_flags=
compiler.elf2hex.extra_flags=
compiler.libraries.ldflags=

...

## Combine gc-sections, archives, and objects
recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}" "-L{build.path}" {compiler.c.elf.flags} {compiler.c.elf.extra_flags} "-T{build.variant.path}/{build.ldscript}" "-Wl,-Map,{build.path}/{build.project_name}.map" --specs=nano.specs --specs=nosys.specs {compiler.ldflags} -o "{build.path}/{build.project_name}.elf" {object_files} -Wl,--start-group {compiler.arm.cmsis.ldflags} -lm "{build.path}/{archive_file}" {compiler.libraries.ldflags} -Wl,--end-group

Error Message I got:

Could you help me to check if there are any mistakes?

Hello,

I find many errors. Could you confirm other examples w/o BSEC is success?

Some errors as bellow are no related to BSEC.

avr-gcc: error: {compiler.arm.cmsis.ldflags}: No such file or directory

avr-gcc: error: nano.specs: No such file or directory

Best regards.

Unless I change platform.txt, it does not give any error on compilation of other examples. 

BSEC's 'Basic' example gives this error: 

C:\Users\yalci\AppData\Local\Temp\ccTU2Ulh.ltrans0.ltrans.o: In function `main':

collect2.exe: error: ld returned 1 exit status

However, when I change this file by following instructions on Github page, the ide starts to give error that I posted on my first message on every example from different libraries and BSEC library.

Could you please share the of the "Arduino AVR Boards" used in your project? You can find your version from the Boards Manager or inside the platform.txt file (line 9).

The latest version of the Arduino AVR Boards I can find is v1.8.3, which seems to come with external libraries support by default. I can successfully compile the basic example for the Arduino Mega 2560 board with the BSEC Software Library v1.5.1474, Arduino IDE v1.8.13 and Arduino AVR Boards v1.8.3.
