BME688 library linking fails in STM32MP1

Hi Biswajeet,

Could you confirm the following information?

Host: STM32MP157, https://www.st.com/en/microcontrollers-microprocessors/stm32mp157.html
Compiler: arm-openstlinux_weston-linux-gnueabi-gcc , download link: https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embe...
Compiling option: you could list them if you have.

Host: STM32MP157 : 
Yes, STM32MP157 is the target device. 

Compiler: arm-openstlinux_weston-linux-gnueabi-gcc or arm-ostl-linux-gnueabi-gcc : both are same.
Yes, Download the SDK v1.2.0 or follow this link en.SDK-x86_64-stm32mp1-openstlinux-20-02-19.tar_v1.2.0.xz to download directly. You have to login to ST inorder to download the SDK. 

After downloading extract the file and run the st-image-weston-openstlinux-weston-stm32mp1-x86_64-toolchain-2.6-openstlinux-20-02-19.sh script for installation and it will install in the default path /opt/st/stm32mp1/2.6-openstlinux-20-02-19.

To make the environment setup please run as below

:~$ source /opt/st/stm32mp1/2.6-openstlinux-20-02-19/environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi

Hi BSTRobin, 

Any update when we'll be expecting the library ?

Hi Biswajeet,

After checking you compiling log, could you refer the following step, compile it again? And give feedback to us. Thanks.
Checking the VFP calculation type for CFLAGS in APP build options and changing 'FABI := hard" to "FABI := softfp'

Hi BSTRobin,

By default, "-mfloat-abi=hard" is defined by the SDK environment file. When it is changed  to "-mfloat-abi=softfp", I am getting compilation errors.
