C语言出现initializerelementisnotconstant错误的原因 C语⾔出现initializerelementisnotconstant错误的原因 当在全局变量定义⼀个指针变量,并动态分配内存后,发现竟然编译不过去,并提⽰ ""initializer element is not constant"":char *buf = malloc(1024);int main() { return 0;};后来知道了,不能将全局...
上面的代码会报initializer element is not constant 错误,错误原因是: C语言初始化一个全局变量或static变量时,只能用常量赋值,不能用变量赋值!(错误就在void* v_p = p_a) 解决办法如下:定义成局部变量就OK了。 #include <stdio.h>inta =1314;int* p_a = &a;intmain(void) {void* v_p =p_a;retu...
initializer element is not constant 问题 在Ubuntu下,比葫芦画瓢,写了一个程序,居然报错!!! 1#include <stdio.h>23floati =3;4intj = *(int*)(&i) ;56intmain (intargc ,char*argv[])7{8printf("i = %f \n", i ) ;9printf("j = %#x \n", j);10return0;11} 对于高手,一眼就能看出...
initializer element is not constant 问题 #include <stdio.h> int a = 1314; int* p_a = &a; void* v_p = p_a; int main(void) { return 0; } 1. 2. 3. 4. 5. 6. 7. 8. 9. 上面的代码会报initializer element is not constant 错误,错误原因是: ...
原因: 全局变量c的值不能在编译时确定,要在执行是确定(编译原理。。) 解决办法: [cpp] view plaincopy #include int a = 1; int b = 2; int c; //只声明 int main() { c = a + b; //在main函数里赋值 printf("c is %d\n", c); return 0; } ...
error: initializer element is not constant error: (near initialization for tca6507_leds1.leds.num_leds) I think the problem is related tostruct led_info *ledsinsideled_platform_data. Is this somehow not a const since it is a pointer? I am particularly baffled sinceled_platform_dataandled...

当在全局变量定义一个指针变量,并动态分配内存后,发现竟然编译不过去,并提示 ""initializer element is not constant"": 1 2 3 4 5 char*buf =malloc(1024); intmain() { return0; }; 后来知道了,不能将全局变量初始化为一个无法在编译时期确定的值。再想想暑假学习的CSAPP中的链接那部分就知道为什么了。
