main.c:10:18: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] 主要原因是在源文件中没有声明函数 未经声明的函数原型一律默认为返回int值(4个byte) 定义赋值的指针变量(8个byte) 所以发生警告
报错:[Warning] cast to pointer from integer of different size [-Wint-to-pointer-cast] 中译:[警告]把指针不同大小的整数(-Wint-to-pointer-cast) 起源:看到了知乎这个问题指针的指针定义为什么用int* ptr,而不是intptr?,一下子没反应过来。借此机会在温习一下指针。 文章描述了这两种差异化的写法 int ...
修改成:p=(void *)((unsigned int)a + (unsigned int)b);错误原因:首先一点,两个地址相加没有意义,地址加一个偏移量才有意义,你一行实质是两个地址相加;如果你想练习使用指针访问变量的值,从而得到1000+11的结果,那么就是int c = *a + *b; 最后结果是一个数字,不是地址,所以不要...
uboot编译出现 warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]我这边的用法是 Writel(val, reg) 其函数操作最后为 reg = val reg其实是一个地址,上层传int 类型,编译器处理的时候要识别为指针, 把警报作为错误处理 * eg:int reg=0xFF00...

When I compile in and64 platform: I can't seem to figure it out. Here's one of the lines it has trouble with:static gboolean scan_freq(gpointer data) { static gint start, mom, max; gint dir = (gint)(data); /// <- cast to pointer from integer of different ...
将int变量转为(void*)时出现错误 error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] 这是由于int类型为32位,指针为long long 64位 解决方法:(voi
char一个字节,unsigned int至少4个字节,把4字节的数据cast为1字节数据可能会warning的啊 64
今天在编写多线程程序的时候,编译过程中出现了如下错误: thread.c: In function ‘main’: thread.c:38:57: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] 后来google了,受这个问题解决的启发http://stackoverflow.com/questions/9251102/warning-cast-to-pointer-from-integ...
