hbcxx:使用“#!/ usr / bin / env hbcxx”使C ++源代码可执行-开源
这段代码在输出时,使用了变量 $related_pins,$timing_types 和 $whens,这些变量只有在相应的 if 语句块中被定义。如果某些语句没有被执行,这些变量将没有定义,因此在输出时会出现编译错误。
为了解决这个问题,你可以在定义变量时,先将它们初始化为空字符串,如下所示:
```
my $pin_name = '';
my $timing_type = '';
my $related_pin = '';
my $when = '';
```
这样,即使相应的 if 语句块没有被执行,这些变量也会有默认值,不会导致编译错误。
