Question

我不明白错误在哪里。为什么这个错误信息：从不兼容的指针类型初始化。朋友，请帮帮我。

const struct _displayout_default
{
const char* length;
const char**  buf;

}DisplayOut_DEFAULT[2] =  
{
    {
    "02", 
    (const char*[]){
        "01",
        "02",
        "03",
        "04"
        }
    },
    {
    "02", 
    (const char*[]){
        "01",
        "02",
        "03",
        "04"
        }
    }
};

MPLAB®C编译器对于PIC32 MCU

编辑（旧答案消失）

不幸的是，我无法使用相同的编译器和相同的选项重现该消息：

T:\>"c:\Program Files (x86)\Microchip\mplabc32\v2.01\bin\pic32-gcc.exe" -g -mlong-calls -DNDEBUG -Os test.c

没有错误。

与pic32mx-gcc-4.5.1.exe同样 - 没有错误。
