Troubles with enum...

ThomasH — Fri, 23 Jun 2006 14:35:34 GMT

I´m a newbie in programming with CodeWarrior and I´m porting software from my old compiler to the CodeWarrior and I faced a very confusing problem:

I had defined the structure:

typedef struct
{

BYTE menu_nr_left;
   BYTE menu_nr_right;
   BYTE menu_nr_up;
   .....

enum
   {
   NUMBER=0,
   TEXT_1=1,

TEXT_2=2
}para_view:2;

unsigned int txt_idx;

.....

}view_tab_t;

During compiling of the sources I get the error message that NUMBER, TEXT_1 and TEXT_2 are not declared. All declarations in this header are working fine except all enum´s. Please can anybody tell me, what I´ve done wrong?

Thanks in advance!

Hello

I assume you are using CodeWarrior for HC12 V4.5. Am I right?

Basically the constants NUMBER, TEXT_1 and TEXT_2 are defined in type view_tab_t. They do not have global scope and are not available outside of a variable of type view_tab_t.

If you wish to test against that constant you have to write:

if (viewTab.para_view == viewTab.TEXT_2) {

where viewTab is defined as

view_tab_t viewTab;

Another alternative to to define the enumerated type and its constant outside of the structured type view_tab_t.

I have encountered the same thing with array definitions using constants defined using enum. The best way is to place the enum definitions in a separate file to give them file scope.

Thanks for your helps!

I defined all enums outside the struct and now all works!
