BSEC library for Azure Sphere

[jeremynz]

Hi,

I posted some of this earlier at the end of this thread https://community.bosch-sensortec.com/t5/MEMS-sensors-forum/BSEC-integration-problem-on-gcc-Cortex-A... but perhaps it was unnoticed as that thread is already marked as solved.

I'm using a BME680 with an Azure Sphere kit. I want to use the BSEC library but I am getting a variety of linking errors.

The Azure Sphere is based off a MT3260, which has a Cortex-A7 core and 2 x Cortex-M4 cores. I want to integrate the BSEC library into my Cortex-A7 application.

I have tried the following versions of libalgosec.a:

• algo\normal_version\bin\gcc\Cortex_A7\libalgosec.a from BSEC_1.4.7.4_Generic_Release.zip

Can someone from Bosch help to provide a precompiled library to resolve these errors? The standard gcc options for the Azure Sphere toolchain are:

-c -x c -I DRIVERS/BME680 -I LIBRARIES -I DRIVERS -I "C:\PROGRAM FILES (X86)\MICROSOFT AZURE SPHERE SDK\SYSROOTS\3+BETA1909\USR\INCLUDE" -I ..\HARDWARE\AVNET_MT3620_SK\INC -g2 -gdwarf-2 -Wall -W"strict-prototypes" -Wswitch -W"no-deprecated-declarations" -W"empty-body" -Wconversion -W"return-type" -Wparentheses -W"no-pointer-sign" -W"no-format" -Wuninitialized -W"unreachable-code" -W"unused-function" -W"unused-value" -W"unused-variable" -W"deprecated-declarations" -O0 -fno-strict-aliasing -fno-omit-frame-pointer -D_POSIX_C_SOURCE -fno-exceptions -std=c11 -fstack-protector-strong -Werror=implicit-function-declaration -B "C:\Program Files (x86)\Microsoft Azure Sphere SDK\Sysroots\3+Beta1909\tools\gcc" -march=armv7ve -mthumb -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a7 -ggdb -fPIC -ffunction-sections -fdata-sections --sysroot="C:\Program Files (x86)\Microsoft Azure Sphere SDK\Sysroots\3+Beta1909"

I believe using the -fPIC -mfloat-abi=hard -fno-short-enums options when compiling BSEC will help resolve my errors.

Yes, it seems like the -fPIC option should be included for all BSEC libraries provided by Bosch, I don't think there's any downside to just including that option on existing builds.

Sorry for the delay between other tasks and setting up the SDK, but please try the attached release using the native toolchain from the Azure SDK.
