编译选项:如果错误是由编译器选项 -Werror=int-to-pointer-cast 触发的,可以考虑移除该选项或将其更改为警告而不是错误。 bash gcc -Wno-error=int-to-pointer-cast -o myprogram myprogram.c 示例代码 假设有以下代码: c #include <stdio.h> int main() { int i = 10; int *ptr = (int...

"Cast from pointer to smaller type 'int' loses information” 从错误内容我们也能看出, 错误出在'int'这里了。 而那份代码也比較早的, 在Xcode5.1之后, 要用uintptr_t来替代int。 把错误语句处的int全换成uintptr_t就可以。 可是, 这样可能会带来很多其它的问题。
Cast from pointer to smaller type ‘int‘ loses information 当void*转换为int时,会报错: Castfrompointer to smaller type ‘int‘ loses information 后来,发现这么修改即可: (int)(size_t)data
error: cast from pointer to smaller type 'unsigned int' loses information 线程池代码上,往往需要输出对应的线程池编号,即(int) pthread_self() 但是在64为机器上可能导致因为int为4字节,指针统统为8字节,所以一般将int改成uintptr_t 即可解决。 即,将(unsigned int)强制类型转换修改成: uintptr_t 即可。
