Include file not found, but builds anyway

drmacro · December 17, 2019, 7:20pm

I’ve read other posts about this, but have not found a solution as yet.

I get this message when I build the project:

#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit (/home/mac/Documents/PlatformIO/Projects/MyProjectName/src/MyCode.c). cannot open source file "something.h"

The line in the code is:
#include <something>.h

I have tried having the file in the …/src directory and the in the …/include directory.

same message with “something.h” or <something.h>in the include statement.

Yet, the project builds successfully, and runs on the target hardware.

So, what’s wrong with my setup?

Executing the Rebuild Intellisense does not help? Also what VSCode version are you using? Placing the header in src/ should definitely work.

drmacro · December 17, 2019, 7:41pm

VSC Version: 1.41.0

I don’t know how to execute rebuild intellisense. And, I see no reference to Intellisense in the URL in your response. I’m probably missing something.

Ok, I found the Rebuild Intellisense Index in the task list.

Executing it produced no change, .h file still not found.

Well I cannot reproduce your problem. I just create a new file, fill it with something and reference it. Following it using Ctrl+Click works.

I’m also using the same VSCode version as you, 1.41.0.

What extensions do you have installed in which version, and what is your PIO core and home version?

drmacro · December 17, 2019, 9:17pm

Same 3.0.1 and 4.1.0

I do note, that you did an include Arduino.h, I’m not using any arduino, so did not use it the header file. (I don’t see how that matters…

Ok, so I was tinkering with something completely unrelated in a project.

In order to find the FreeRTOS .h files I had to have this:
#include "freertos/FreeRTOS.h"

rather than:
#include "FreeRTOS.h"

So I looked at the project that prompted this post and yes, it required the same.

So, I tried this:
#include <./dmx.h>

And, it no longer throws the error.

So, what is wrong with my install, defualts, etc.?

Can you post the structure of the project and the contents of the .vscode/c_cpp_properties.json?

drmacro · December 18, 2019, 3:32pm

c_cpp_properties.json:

This doesn’t show all files. Can you do a tree command or show the file structure in VSCode? Also the contents of the platformio.ini and any source or header files please.

maxgerhardt · December 18, 2019, 7:33pm

Well the folder is right there in the includes so dmx.h should be found.

Can you show

the contents of the source files
list of installed VSCode extension

drmacro · December 18, 2019, 7:46pm

This produces no error:

#include <stdint.h>
#include <string.h>
#include <./dmx.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "freertos/queue.h"
#include "esp_attr.h"
#include "soc/rtc.h"
#include "driver/mcpwm.h"
#include "driver/timer.h"
#include "driver/gpio.h"

This does:

#include <stdio.h>
#include <stdint.h>
#include <string.h>
#include <dmx.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"

extensions

drmacro · December 18, 2019, 7:47pm

I apparently don’t know how to include images in a post…

I took an image of the extensions…
But the list of enabled:

C/C++
C++ Intellisense
PlatformIO IDE

Also installed:

openHAB
Python

maxgerhardt · December 18, 2019, 7:53pm

Can you please disable the “C++ Intellisense” plugin from austin and restart VSCode. No special Intellisense plugin is needed which not provided by the C/C++ extension.

drmacro · December 18, 2019, 8:04pm

I have no idea when that was installed.

I disabled it.

restart VSC.

Now:
Not found:
#include <dmx.h>

And, not found:
#include <./dmx.h>

maxgerhardt · December 18, 2019, 8:05pm

No change after the Rebuild Intellisense Task is executed?

drmacro · December 18, 2019, 8:06pm

Tried that and Update project libraries. In both cases (<dmx.h> and <./dmx.h>)

maxgerhardt · December 18, 2019, 8:11pm

Does uninstalling instead of disabling the extension make a difference?

drmacro · December 18, 2019, 8:14pm

Uninstalled, restarted, no difference.

But, it does now recomend that I install C++ Intellisense austin
