“expression is not an integer constant expression”问题解析 1. Integer Constant Expression 的含义 整数常量表达式(Integer Constant Expression)是指在编译时就能确定其值的整数表达式。这种表达式通常不包含任何运行时才能确定的值或操作,如变量、函数调用等。整数常量表达式通常用于需要编译时常量的场合,如数组大小、...

resulting_string <= integer'image(87465); to: resulting_string <= integer'image(some_int_var); I get an "Expression is not constant" error. What is the correct way to convert an always changing integer variable (that could be any int within the integer limits) to a string...
time is not a reserved keyword, nor are any type names. So you can use it to confuse yourself thoroughly (and it works because VHDL is all context driven) signal time : std_logic; signal std_logic : integer range 0 to 153; signal integer : real range -0.1 to 100.66; Translate...
如果打开注释的那一块代码会报一个错误提醒Expression is not an integer constant expression GlogConfig.h中声明的pram(extern NSInteger const pram;)对外是一个全局不可变的一个变量. 我们在GlogConfig.m中对pram进行了初始值进行定义(const NSInteger pram = 0x11;),这里parm是一个局部常量不可变的. ...
意思是:当使用extern在.h中声明常量,在.m中给该常量赋值,意味着外部不能知道该常量的值,只能使用,而switch中case的值是需要在编译阶段就要知道case的具体常量值,但是这个是extern无法做到的。
