Hi, 
In order to compile the BSEC library from Bosch, I should be able to change the used platform.txt file to the following.
I already did this in the standard Arduino location, such that I can compile in the Arduino IDE. However, when compiling in visualMicro it uses a different linker command than the one i specified in platform.txt. 
I also tried adding the board.txt file with the specific command in visualMicro, but it has no effect.
What is the location of the platform.txt file used in visualMicro compiling for a SAMD21 architecture?

Hi,
Thanks for the reply!
I changed the linker script in the samd21 platform.txt file (line 96, ..\AppData\Local\Arduino15\packages\arduino\hardware\samd\1.6.19) to the following, such that it includes a precompiled library. 
I already tried restarting and rescanning, however without success. 
Is there a way to check that it is referring to the correct platform file?
I don't really see another possibility as to why it would compile in the arduino IDE and not in visualMicro?

The following is line 96 in platform.txt after change:

recipe.c.combine.pattern="{compiler.path}{compiler.c.elf.cmd}"  "-L{build.path}" {compiler.c.elf.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 {compiler.c.elf.extra_flags} "{build.path}/{archive_file}" -Wl,--end-group 

Thanks!

If i hardcode the {compiler.c.elf.extra_flags} to the correct path and library to include, everything works.
So for some reason visual micro omits this part or can't find this parameter.
