缺少括号围绕初始化

编译器是在MPLAB 8 GCC，dsPIC33系列版本3.30c缺少括号围绕初始化

// in the structurer is wrong. 
// the 2nd block give warning, but the data is correct... why??

是否定义了“tSCF”？ –

看起来你在这行的开头错过了{：

(uint32) 0x00000000}, {(uint8) 2} // Filter 15

他承认在代码中（请参阅顶部的注释） –

大概一个未关闭在文件中撑起更高的位置......我们需要在上下文中看到它 - 将文件放在它自己的文件中，第二个数组编译得很好。我改变了使用查找和替换的类型，这不会产生错误或警告与

gcc -c -Wall -Wextra

所以，错误必须在别的地方。

#include <stdint.h> 
const uint32_t static_can_filter[] = { 
    (uint32_t) 0x01FFFFFF, (uint8_t) 2, // Filter 0 (Process data) 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 1  
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 2 (receive P2P-Message) 
    (uint32_t) 0x0000FF00, (uint8_t) 2, // Filter 3 (receive P2P-Message) 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 4 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 5 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 6 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 7 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 8 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 9 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 10 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 11 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 12 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 13 
    (uint32_t) 0x00000000, (uint8_t) 2, // Filter 14 
    (uint32_t) 0x00000000, (uint8_t) 2 // Filter 15

假设TSCF定义类似如下：

typedef struct tSCF { 
    uint32 a; 
    uint8 b; 
} tSCF;

你想要什么可能看起来如下：

const tSCF static_can_filter[] = { 
    { (uint32) 0x01FFFFFF, (uint8) 2 }, // Filter 0 (Process data) 
    { (uint32) 0x00000000, (uint8) 2 }, // Filter 1 
    [...]

用大括号每个初始化初始化数组的不同元素。您的问题{(uint32) 0x01FFFFFF}, {(uint8) 2},的第一个表格最终会生成阵列的两个成员（每个成员的a设置为给定值，并且b设置为零）。您可以通过添加约束的明确阵列（这将导致编译器抱怨过多的初始化从你的问题看这个你的榜样

第二种形式没有你它到底要什么：当没有任何括号并且数组元素是一个结构体，这些值被赋值给连续的字段。这里有一个可选的警告（可能是-Wall或类似的东西），因为这个答案给出的表单使你的意图更清晰一些。
