I do not understand where the error.
why this error message:
initialization from incompatible pointer type.
Help me please, friends.

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"
        }
    }
};

    Edit (old answer gone)

    Unfortunately, I’m not able to reproduce the message with the same Compiler and same options:

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

    No Errors.

    Likewise with pic32mx-gcc-4.5.1.exe – No Errors.

    Details:

    Source

    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"
        }
    }
};    

int main(int argc, const char *argv[])
{

    return 0;
}
