Using my own library

Antoine · February 24, 2020, 9:40am

Hello ,

I’m trying to use my own library (in local) in platformio.
This is my platformio.init:

[env:eval_f072vb]
platform = ststm32
board = eval_f072vb
framework = stm32cube
build_flags = 
    -D USE_FULL_LL_DRIVER
    -D USE_HAL_DRIVER
lib_extra_dirs =
    C:\Users\antoi\OneDrive\Bureau\LUOS\Luos_Dev\Luos
    C:\Users\antoi\OneDrive\Bureau\LUOS\Luos_Dev\Robus

I include my library “luos” in the main.c:

/* Includes ------------------------------------------------------------------*/
#include "main.h"
#include "adc.h"
#include "crc.h"
#include "dma.h"
#include "rtc.h"
#include "usart.h"
#include "gpio.h"
/* Private includes ----------------------------------------------------------*/
/* USER CODE BEGIN Includes */
#include "luos.h"
/* USER CODE END Includes */

I use a function of this library:

/* USER CODE BEGIN 2 */
  luos_init();
  /* USER CODE END 2 */

This is the error i have :

I don’t understant because VSCode recognize the function but don’t seems compile the library:

This dependency graph looks weird. What’s the folder structure of C:\Users\antoi\OneDrive\Bureau\LUOS\Luos_Dev\Luos and C:\Users\antoi\OneDrive\Bureau\LUOS\Luos_Dev\Robus? If these are directly the library folders, you should try just adding C:\Users\antoi\OneDrive\Bureau\LUOS\Luos_Dev to the lib_extra_dirs and then adding

lib_deps = 
    Luos
    Robus

to the platformio.ini.

However,

Could also come from using C++ code in C in the wrong way. Are your libraries written in C++ or C?

Antoine · February 24, 2020, 11:22am

Thank you for your quick answer
My libraries are written in C.
I have a better dependencie graph by doing this in platformio.ini

[env:eval_f072vb]
platform = ststm32
board = eval_f072vb
framework = stm32cube
build_flags =
-D USE_FULL_LL_DRIVER
-D USE_HAL_DRIVER
lib_extra_dirs =
C:\Users\antoi\OneDrive\Bureau\LUOS\Luos_Dev
lib_deps =
Luos
Robus

But now VScode doesn’t find my library and i think it just see it like a piece of code
and not a library.

To solve that I’d have to know…

Specifically to see whether they conform to the needed default library structured explain in the README. If not, the creation of library.json is necessary which simply declares the include paths which are missing now. (an example)

It seems that VSCode only see robus in libdeps.
In fact Robus depend of Luos so i tried to make this json file but nothing change:

     "name": "Luos",
     "keywords": "robus,network",
     "description": "distributing operating system",
     "version": "1.0",

       "name": "Luos",
       "url": "https://luos-robotics.com"
     },
     "licence": "MIT",
     //"platforms": "espressif32",
     "build" : {
       "flags": [
         "-I Inc",
         "-I OD",
         "-I board/lo",
       ]
     },

     "dependencies":
   [
       {
           "name": "Robus",
       }
   ]

   }```

Does the project compile now and it’s just an Intellisense error? Are you getting the same error?

You put a comments in a JSON file and the JSON parser doesn’t crash on you?

Besides that the JSON file looks good, can you share a reproducable example for the project?

Antoine · February 25, 2020, 9:07am

Hi
I have the same error

* Looking for luos.h dependency? Check our library registry!
*
* CLI  > platformio lib search "header:luos.h"
* Web  > https://platformio.org/lib/search?query=header:luos.h
*
**************************************************************

 #include "luos.h"
          ^~~~~~~~
compilation terminated.
*** [.pio\build\eval_f072vb\src\main.o] Error 1

The comment in the JSON file doesn’t make crash the JSON parser put i have the impression
that my json has no effect like my library.

maxgerhardt · February 25, 2020, 10:52am

This Again . If it’s reproducable I can work on it.

Also are you sure you’re putting your two library.json file in the respective folder of the library?

You should be able to see the new -I flags when you run “Verbose Compilation” (or just pio run -v). If not the library.json is malformed or in the wrong place.

Antoine · February 25, 2020, 1:08pm

Yes i made a project which reproduce the error
How can i share it whith you ? (it’s a folder containing my library and a platformIO project)
structure of the folder:
-Driver (folder generate by cub_mx)
-Inc(folder generate by cub_mx)
-lib(folder that i create containing LUOS library)
-Project(PlatformIO project)
-Src(folder generate by cub_mx)

Antoine · February 25, 2020, 1:21pm

Normaly if you compile the platformIO project you should get this error :

Either a github.com repository or a google drive / dropbox download would be appreciated

Antoine · February 25, 2020, 1:33pm

Yes of course

Here is the google drive link : Project – Google Drive
