undefined reference to `tud_vendor_n_write'

Hi,
my target board is raspberry pi pico.
I am trying to build a simple USB device with 2 vendor endpoint.
My tusb_config.h looks like this:

#ifndef CFG_TUD_ENDPOINT0_SIZE
#define CFG_TUD_ENDPOINT0_SIZE 64
#endif

//------------- CLASS -------------//
#define CFG_TUD_HID 0
#define CFG_TUD_CDC 0
#define CFG_TUD_MSC 0
#define CFG_TUD_MIDI 0
#define CFG_TUD_VENDOR 1

#define CFG_TUD_VENDOR_RX_BUFSIZE 64
#define CFG_TUD_VENDOR_TX_BUFSIZE 64

and configuration descriptior is like this:

uint8_t const desc_configuration[] =
{
// Config number, interface count, string index, total length, attribute, power in mA
TUD_CONFIG_DESCRIPTOR(1, 1, 0, CONFIG_TOTAL_LEN, TUSB_DESC_CONFIG_ATT_REMOTE_WAKEUP, 100),

TUD_VENDOR_DESCRIPTOR(0xFF,0,0x01,0x81,0x40)
};

and my main.c looks like this:

void tud_vendor_rx_cb(uint8_t itf)
{
tud_vendor_read(usb_rx_buffer,64);
usb_rx_ready = 1;
}

int main(void)
{
board_init();
tusb_init();

while (1)
{
    tud_task(); // tinyusb device task

    if (tud_suspended())
    {
        // Wake up host if we are in suspend mode
        // and REMOTE_WAKEUP feature is enabled by host
        tud_remote_wakeup();
    }

    if(usb_rx_ready)
    {
        tud_vendor_write(usb_rx_buffer,64);
        memcmp(usb_rx_buffer,0,64);
        usb_rx_ready = 0;
    }

}

return 0;

}

but when building the project, the compiler gives the error:
undefined reference to tud_vendor_n_write' undefined reference to tud_hid_get_report_cb'
undefined reference to `tud_hid_set_report_cb'

even though i am not using HID. after manually adding the usb hid callbacks and removing the tud_vendor_write it compiles.
What excatly is the issue here?

Well, it looks like make was linking to previous object files that were build, after doing make clean and rebuilding, it started to compile successfully.
