I am using NCS Connect SDK version 2.6.0
I am trying to create an array of models and found a problem with using Zephry macros in C++ projects. My main.cpp is as below
#include <zephyr/bluetooth/bluetooth.h>
#include <zephyr/bluetooth/mesh.h>
#include <zephyr/sys/printk.h>
int main(void)
{
printk("Hello Worlds! %s\n", CONFIG_BOARD);
static const struct bt_mesh_model models[] =
{
BT_MESH_MODEL_CFG_SRV,
};
return 0;
}
BT_MESH_MODEL_CFG_SRV is defined in cfg_srv.h as
#define BT_MESH_MODEL_CFG_SRV \ BT_MESH_MODEL_CNT_CB(BT_MESH_MODEL_ID_CFG_SRV, \ bt_mesh_cfg_srv_op, NULL, \ NULL, 1, 0, &bt_mesh_cfg_srv_cb)
BT_MESH_MODEL_CNT_CB is defined in access.h
/**
* @brief Composition data SIG model entry with callback functions
* with specific number of keys & groups.
*
* This macro uses compound literal feature of C99 standard and thus is available only from C,
* not C++.
*
* @param _id Model ID.
* @param _op Array of model opcode handlers.
* @param _pub Model publish parameters.
* @param _user_data User data for the model.
* @param _keys Number of keys that can be bound to the model.
* Shall not exceed @kconfig{CONFIG_BT_MESH_MODEL_KEY_COUNT}.
* @param _grps Number of addresses that the model can be subscribed to.
* Shall not exceed @kconfig{CONFIG_BT_MESH_MODEL_GROUP_COUNT}.
* @param _cb Callback structure, or NULL to keep no callbacks.
*/
#define BT_MESH_MODEL_CNT_CB(_id, _op, _pub, _user_data, _keys, _grps, _cb) \
{ \
.id = (_id), \
.pub = _pub, \
.keys = (uint16_t []) BT_MESH_MODEL_KEYS_UNUSED(_keys), \
.keys_cnt = _keys, \
.groups = (uint16_t []) BT_MESH_MODEL_GROUPS_UNASSIGNED(_grps), \
.groups_cnt = _grps, \
BT_MESH_MODEL_UUIDS_UNASSIGNED() \
.op = _op, \
.cb = _cb, \
.user_data = _user_data, \
}
Which is where the problem lies. The macro is defined for C language only and cannot be used with a C++ compiler as it uses compound literals.
Does anyone have any suggestion to resolve this impase
Appreciate any suggestions.
Thanks
