gcc 警告：标量初始值设定项周围有大括号

我有如下定义的查找表，并且正在使用 GCC。当我编译时，我收到警告

warning: braces around scalar initializer

这个警告是什么意思？我应该如何初始化这个LUT？我在初始化这个结构时犯了错误吗？

Help!!

typedef struct TECH
{

    float velocity1, velocity2;
    float temp;
    float measure;

    int id;
    float storage[64];

}TECH;

您应该删除大括号：{ and }围绕单一值。
