Cryptoauthlib-匿名联合只能有非静态数据成员-分段错误 我试图用CudioAuthLIB编译一个C++程序，在ATCAIIFACE中得到这个（匿名联盟只能有非静态数据成员）错误。我认为这是c11特性，与c++不兼容：

ATCA_STATUS atinit（ATCAIface）时，我遇到了一个分段错误。。。我不直接调用这个函数。我调用atcab_init（&cfg_ateccx08a_i2c_default）
有没有一种方法可以在不修改界面的情况下使用它？为什么会出现分段错误
我的硬件设置是一个CM3，ATEC608A连接到I2C 1。界面已打开，我可以查询它。是否需要将默认接口修改为正确的设备类型和正确的I2C接口？当我这样做的时候，我得到了同样的分割错误
编辑：
示例代码
#include <iostream>
#include "cryptoauthlib.h"
int main(int argc, char *argv[])
{
uint8_t random_number;
atcab_init(&cfg_ateccx08a_i2c_default);
ATCA_STATUS status = atcab_random(&random_number);
std::cout << "status: " << (int)status << std::endl;
return 0;
}
建造
编辑5：
发现我必须在我的CMAKE项目中明确地执行设置（ATCA_HAL_I2C TRUE）
。。。不幸的是，作为一种选择，它对我不起作用
现在我在这里又遇到了一个分段错误：
ATCA_STATUS atcab_random(uint8_t *rand_out)
{
...
ATCACommand ca_cmd = _gDevice->mCommands;
...
}
我在github上打开了它。我发现了错误。硬件抽象层无法连接，因为i2c总线.atcai2c.bus
的默认总线设置被设置为2，它需要为1，否则它将找不到i2c设备
ATCAIfaceCfg cfg_ateccx08a_i2c_default = {
.iface_type = ATCA_I2C_IFACE,
.devtype = ATECC608A,
.atcai2c.slave_address = 0xC0,
.atcai2c.bus = 1,
.atcai2c.baud = 400000,
//.atcai2c.baud = 100000,
.wake_delay = 1500,
.rx_retries = 20
};
现在，我可以通过以下方式从芯片中获取修订版、序列号和随机数：

{
ATCAIfaceType iface_type; // active iface - how to interpret the union below
ATCADeviceType devtype; // explicit device type
union // each instance of an iface cfg defines a single type of interface

std：：cout在我的机器上工作。但是我必须弥补很多缺失的部分。你能确保你的示例代码完整并编译（产生编译器错误）吗？我没有将联合更改为struct@john，我删除了未命名联合中的结构名称。@Eljay我添加的示例代码仍然没有按照给定的方式编译。我的调整版本必须定义ATCAIfaceType、ATCADeviceType和ATCA_状态。我遇到了另一个错误，我通过给匿名联合一个名称修复了该错误（不再匿名）。但是默认接口定义不起作用。因为编译器找不到联盟的成员。我正在使用gcc 7.3.1…github上有人告诉我必须使用-DATCA_halu_I2C作为C编译器标志。但是我现在得到了对HAL_I2C_init的未定义引用
