Can't include libraries in visual code studio

[Manu_30]

Hello,

I try to do a little code for STM32F103 MCU using Visual Code Studio with STM32 VS code Extension.

I can generate and compile base code using STM32CubeMX importation feature.

But I'm stuck with adding external libraries to the project.

What i've done is to modify the "c_cpp_properties.json" file of the project to add the path to the library I want to use.

Here the current file :

{
    "version": 4,
    "configurations": [
        {
            /** 
             * ms-vscode.cmake-tools plugin should be installed.
             * 
             * It provides data for C/C++ plugin,
             * such as include paths, browse paths, defines, etc.
             */
            "name": "STM32",
            "includePath": [
                "lib/ssd1351"
            ],
            "configurationProvider": "ms-vscode.cmake-tools",
            //"intelliSenseMode": "${default}",
            "intelliSenseMode": "gcc-arm"
        }
    ]
}

But when I include the ssd1351.h header in the main.c file, it fail :

/* Private includes ----------------------------------------------------------*/
/* USER CODE BEGIN Includes */
#include "ssd1351.h"
/* USER CODE END Includes */

Can someone point me to the solution for including external libraries in an VScode project ?

Thank you

I finally found one solution :

I added the path to the "CMakeLists.txt" file located in "cmake" folder.

Anyway, if there is a better/more standard way to solve the problem, I'd like to know about it.

Thank you,

Manu

Hello @Manu_30, 

Well done that's it, you need to include and link the external library ssd1351 to your CMakeLists.txt 

• Add the include path for the ssd1351 library in target_include_directories
• Add the ssd1351.c source file to target_link_libraries

Thank you Sarra.S.

I don't understand about

The file we speak about is this one :

./project_Name_Directory/cmake/stm32cubemx/CMakeLists.txt

Correct ?

So, in this file I wrote :

target_link_directories(stm32cubemx INTERFACE
    ../../lib/ssd1351/ssd1351.c
)

Now I can use

#include ssd1351.h

And the code compile.

BUT, as soon as I use a function from the librairie, I can't compile anymore. I have an error message :

C:/Users/manu/Documents/Code/STM32F103C8T6/First/Core/Src/main.c:101: undefined reference to `SSD1351_Unselect'

while Intellisense find the function.

What did I miss ?

Thank you,

Manu

in target_include_directories: Add the path to the ssd1351 header files

in target sources, Add the path to the ssd1351 source files

target_link_libraries: links the library to the project

 check: cmake-properties(7) — CMake 3.31.0-rc3 Documentation

c_cpp_properties is only for the editor so it knows where to find the header files and definitions so it can do proper syntax highlighting and suggestions.

Hi,

I can't make it work :

Plus, I updated SMT32CubeMX to version 6.12.1 and since, STM32F103C8Tx_FLASH.ld is not correct ! It miss the RAM processors and with a straight import in VScode using STM Code extension and using "import Cmake project", the compilation fail. I have to modify the STM32F103C8Tx_FLASH.ld file per hand and add the relevant and missing section :(

Are you sure "../../" is correct? That's two folders up.

[Manu_30]

I'm not sure, but I tried many, many possibilities without success. Even the absolute path don't operate.

Unfortunately there is no documentation about this...
