Question

I can’t get rid of compiler warning “assignment makes pointer from integer without a cast” in following case:

    int sql_user(char** mysql_user_name, char** mysql_password, char** mysql_server, char **mysql_serverport, char** mysql_socket)
{
    int retval = -1;
    char **sub;
    char *contents;
    if(g_file_get_contents("mysqlsrv.def", &contents, NULL, NULL))
    {
        sub = g_strsplit(contents, "\n", -1);
        //here compiler warning: assignment makes pointer from integer without a cast

        *mysql_user_name  = sub[0];
        *mysql_password   = sub[1];
        *mysql_server     = sub[2];
        *mysql_serverport = sub[3];
        *mysql_socket     = sub[4];
        if (!strlen(sub[4])) *mysql_socket = NULL;
        retval = 0;
    }
    return retval;
}

Additionaly, In sub[4] is empty string (“”). Is here a way to save NULL instead to text file so it can be readed later as NULL without If (!strlen… condition?

Any help would be appreciated.

Sounds like g_strsplit() is not known (declared), so the compiler is assuming the default return type of int.
I’d check your include files to make sure the one declaring g_strsplit() is included.
