Problem with nested structs in BME680-Driver / I²C-init

[rk-sTEk]

The issue

I try to use the BME680-driver on an ESP32C6 with VSC on Linux with newest ESP-IDF (v5.1.2).
Unfortunately the controller went in an error by init the sensor. After a debug session I realized, that there is a wrong variable initialization.

the definitions in bme680.h:

/**
 * BME680 sensor device data structure type
 */
typedef struct
{
    i2c_dev_t i2c_dev;              //!< I2C device descriptor

    bool meas_started;              //!< Indicates whether measurement started
    uint8_t meas_status;            //!< Last sensor status (for internal use only)

    bme680_settings_t settings;     //!< Sensor settings
    bme680_calib_data_t calib_data; //!< Calibration data of the sensor
} bme680_t;


//Test-Dev without the first struct
typedef struct
{
 
    bool meas_started;              //!< Indicates whether measurement started
    uint8_t meas_status;            //!< Last sensor status (for internal use only)

    bme680_settings_t settings;     //!< Sensor settings
    bme680_calib_data_t calib_data; //!< Calibration data of the sensor
} bme680t1;

typedef struct
{
   i2c_dev_t i2c_dev0;              //!< I2C device descriptor
} bme680_t_1;

the definitions in i2cdev.h:

/**
 * I2C device descriptor
 */
typedef struct
{
    i2c_port_t port;         //!< I2C port number
    i2c_config_t cfg;        //!< I2C driver configuration
    uint8_t addr;            //!< Unshifted address
    SemaphoreHandle_t mutex; //!< Device mutex
    uint32_t timeout_ticks;  /*!< HW I2C bus timeout (stretch time), in ticks. 80MHz APB clock
                                  ticks for ESP-IDF, CPU ticks for ESP8266.
                                  When this value is 0, I2CDEV_MAX_STRETCH_TIME will be used */
} i2c_dev_t;

typedef struct
{
    i2c_port_t port;         //!< I2C port number
    i2c_config_t cfg;        //!< I2C driver configuration
    uint8_t addr;            //!< Unshifted address
    SemaphoreHandle_t mutex; //!< Device mutex
    uint32_t timeout_ticks;  /*!< HW I2C bus timeout (stretch time), in ticks. 80MHz APB clock
                                  ticks for ESP-IDF, CPU ticks for ESP8266.
                                  When this value is 0, I2CDEV_MAX_STRETCH_TIME will be used */
} i2c_dev_t_stek;

the declarations:

    bme680_t sensor;
    bme680t1 sensor2;
    bme680_t_1 sensor1;

    i2c_dev_t i2c_dev;
    i2c_dev_t_stek i2c_dev1;

The variables (breakpoint after the declarations) are shown in the picture.

What you see: The nested structs are absolutely wrong - and I don't know how and why. The compiler(?) uses the wrong struct definitions. And...after a nested struct the the definition in the typedef stops.

What is going wrong here?

Which SDK are you using?

esp-idf

Which version of SDK are you using?

v5.1.2

Which build target have you used?

• esp32
• esp32s2
• esp32s3
• esp32c2
• esp8266
• other

Component causing the issue

BME680, I2CDEV
