Sorry, I tried to change the name of the folder, but I forgot to update everything before I sent it to you. I changed my previous reply. The issue was in the CMakeLists.txt, line 13. Change it from:

set(mylib_src_dir ${CMAKE_CURRENT_SOURCE_DIR}/bsec)

set(mylib_src_dir ${CMAKE_CURRENT_SOURCE_DIR}/bsec_lib)

Best Regards,

thank you sir , i have done as you suggested but i got this error. (in attached image )

Please find the attached zip file , attached file is modified as you suggest .

Ok, so to add a ".a" library to an NCS project, you need to add the path to the library and it's header files. One way to do it is like this:

Create this folder structure by creating a new folder called bsec_lib next to your src folder (you can place it anywhere, but I will use this location for demonstration).

inside the bsec folder, create two folders. One called "inc" and one called "lib".

In the library folder that you downloaded externally, copy the libalgobsec.a file from BSEC_1.4.8.0_Generic_Release_updated_v3\algo\normal_version\bin\gcc\Cortex_M4\libalgobsec.a into your new "lib" folder, and copy the two .h files from the same folder into your "inc" folder.

Now go to your prj.conf file and remove most of your configurations. All you need are these (in order to compile, you may need more later):

CONFIG_NEWLIB_LIBC=y
CONFIG_SENSOR=y
CONFIG_BME680=y

Then open your CMakeLists.txt file to add your library. I did it like this:

# SPDX-License-Identifier: Apache-2.0
cmake_minimum_required(VERSION 3.20.0)
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(hello_world)
target_sources(app PRIVATE src/main.c)
target_sources(app PRIVATE src/bme680.c)
target_sources(app PRIVATE src/bsec_integration.c)
target_sources(app PRIVATE src/bsec_serialized_configurations_iaq.c)
zephyr_library_include_directories(src/)

add_library(my_library STATIC IMPORTED GLOBAL)

set(mylib_src_dir   ${CMAKE_CURRENT_SOURCE_DIR}/bsec_lib)

set(MYLIB_LIB_DIR     ${mylib_src_dir}/lib)
set(MYLIB_INCLUDE_DIR ${mylib_src_dir}/inc)

set_target_properties(my_library PROPERTIES IMPORTED_LOCATION ${MYLIB_LIB_DIR}/libalgobsec.a)
set_target_properties(my_library PROPERTIES INTERFACE_INCLUDE_DIRECTORIES ${MYLIB_INCLUDE_DIR})

target_link_libraries(app PUBLIC my_library)

And then it compiled without any errors.

Best regards,

Edvin

than you sir for prompt reply , As I already explained i con't create same error , I have shared all file i am working on .

my goal is clear i want to build my project file as share as zip , i am ready to do modification in all file as you want but i don't want to change main.c file .

my question is same

"CMake script for add eternal libaray ( BSEC ) to test Bosch sensor raeding?"

i already shared BSEC file Library download link and downloaded zip file as well .

you can ignore all file except main.c file .

1. Bme860 and adxl362 both sensor are supported by nordic ,

if you resolve my one problem rest problem resolve automatically .

2. i learn how to add any header file for any project , but this is not sufficient for achieve my goal ,if you have download bsec_1-4-8-0_generic_release_updated_v3.zip file as i share in previous post you can see there was

a folder "config" which contain c file and header files , i don't know how to provide path to tis folder

3. i want to make a project file by which i can compile main.c file (as shared in zip name"bsec").

yes Sir, this file is same and i am getting same error.

That time i have no solution so i using hit and trial method so , error keep changing with my effort .

I don't make any changes in rest files , i changed only CMake file script .I you can modify it , my desire is same as in my first post .

i also shared CMake file in my old post you can compare it with ZIP i make several changes in only in CMake file.

Hello,

When I try to build your application, it says:

Do you also get this if you unzip and try to compile the project that you sent? Did you send the correct project?

Can you send the project that you used to get the error that you mentioned below?

What does it say when you try to upload it? You can also try to use the button insert -> "image/video/file":

And then click the text that says "upload":

Sir , i tried but not able to post zip file ,can you suggest another way for share file.?

RE: CMake script for add eternal libaray ( BSEC ) to test Bosch sensor raeding?

Edvin — Tue, 19 Apr 2022 10:43:43 GMT

You should be able to just "drag and drop" the zip folder into the text window where you are typing. If you get an error, try to delete the build folder before you zip the folder, to reduce the size (significantly).

Hello,

Sorry for the late reply. We have had a public Holiday in Norway. Can you please zip the project that you are trying to compile and upload it here, then I can navigate it and see if I can find out what's missing?

What dependencies is that? Can you show me something, like a screenshot or a file?

I am trying to help you with this, but I don't have your project or your files, and hence, I don't know how to reproduce the issues that you are seeing, and therefore, I don't know the solution yet.

nordic officially support Bosch Sensor data that's why i am trying nordic thingy91 board . if there was no soliton available then why nordic says about support.

I think you should focus on getting the project to compile before you start tweaking configurations.

I still don't have access to the bsec files.

[quote user="Edvin Holmseth"]

These all look quite similar, so solving one will either solve all, or at least show how to solve all, so let us look at the first one, on line 140 in bsec_integration.c.

You are using a parameter/function called bsec_update_subscription. What is this? Is it a function or a parameter? And where is it defined? I see that you include bsec_integration.h from main.c. Do you include bsec_integration.h from bsec_integration.c as well?

[/quote]

Can you please check this?

I am not familiar with the bosch sensor libraries, so I don't know these files in and out, but you should be able to figure this one out.

In line 140 in bsec_integration.c you call bsec_update_subscription, but the compiler can't see where this is declared.

The same applies to:

bsec_integration.c line 417 with bsec_do_steps

bsec_integration.c line 186 with bsec_init

bsec_integration.c line 207 with bsec_set_state

bsec_integration.c line 196 with bsec_set_configuration

bsec_integration.c line 539 with bsec_get_state

bsec_integration.c line 521 with bsec_sensor_control

These all look quite similar, so solving one will either solve all, or at least show how to solve all, so let us look at the first one, on line 140 in bsec_integration.c.

It may also be that the compiler is not looking in the src folder for header files (not sure if this is set by default). Try adding this last line to your CMakeLists.txt file:

cmake_minimum_required(VERSION 3.20.0)
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(hello_world)
target_sources(app PRIVATE src/main.c)
target_sources(app PRIVATE src/bsec_integration.c)
target_sources(app PRIVATE src/bme680.c)
zephyr_library_include_directories(src)

Also, I noticed that you have some spaces (whitespace) after the lines "target_sources(app PRIVATE src/main.c) "

Try removing these. These files are a bit sensitive. The same applies to your prj.conf file if you are going to do changes there in the future.

If I am going to be able to tell more exactly why it is failing, then I would need to see more from your project. At least bsec_integration.h and bsec_integration.c.

RE: CMake script for add eternal libaray ( BSEC ) to test Bosch sensor raeding?

Mohit Nama — Tue, 05 Apr 2022 06:06:24 GMT

Sir now i explain situation step by step. in odder to interface with BSE i have taken following step . Please correct me where i was wrong .

Step 1: Download library from https://www.bosch-sensortec.com/software-tools/software/bsec/ offical ink on nrodic site.

Step 2: after extracting the file . i have created a folder in name" bsec" you can see the path in image

Step3: copy file from bsec_ito_example (1LHS) to scr folder of my "bsec" fle(2RHS)

( 1 ) (2)

Step4: change name from of "bse_ito_example " which contain the main code (1)

copy and rename in my application folder(2) (i add zephyr library for print_k in main file , remain code is same )

(1) (2)

Step5: As i learn from Nordic academy "ho to add external header file " and take steps as suggested .

My CMake file look like

cmake_minimum_required(VERSION 3.20.0)
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(hello_world)
target_sources(app PRIVATE src/main.c)
target_sources(app PRIVATE src/bsec_integration.c)  
target_sources(app PRIVATE src/bme680.c)

Step6: As usual is add new application in VS code on making Build directory by selecting Thingy91_nrf9160

Terminal shows ERROR
