Eclipse show red higligh in somes lines but compiles ok

[iotdeveloperfw]

Hi, I'm using Espressif-IDE Version: 2.11.1 Build id: 20231027-0959 ESP_IDF: 4.4.6 ESP32_Arduino: 2.11.1, I've noted that in differents ECLIPSE ide's compiles ok the code but allways appears red lines highligted in some code lines and a kind of insect (hehehe) at the begining of the line why it happens?? I can compile, run and debugging sucessfully but it sometimes distract us. For example I compile the following code.


#include <functional>
namespace SIXCOMMCU
{

using rxCallback = std::function<void(uint8_t* data, unsigned int data_len)>;

}

But I got a message showing the message: Type 'std::function<void(uint8_t* data, unsigned int data_len)>' could not be resolved

But all compiles ok and run as well.

Thank you in advance for your time.

Looks like some include path are not known by the editor, so can't resolve...
Is this a IDF plugin feature ?
