enum C, global variable error: variable has initializer but incomplete type

I used enum to have boolean variables in C using following code in header file:

enum myBool { FALSE = 0, TRUE = 1}; typedef enum _myBool Bool;

then I defined some global Bool variables with: extern Bool low;

then when I tried to initialize the variables to false in another .c file with Bool low = FALSE I get the error variable 'low' has initializer but incomplete type.

How can I fix this? Thanks so much!!

then I defined some global Bool variables with: extern Bool low;

so you have declared it in the another file. otherwise you will get linker error

You have defined your enum as myBool not _myBool so you need to change

typedef enum _myBool Bool;

to

typedef enum myBool Bool;
