RE: request for member in something not a structure or union (yaccparse error)

[Krishna Murthy Gudipati]

Hello Tim,

I thank you very much for the info. I have defined it as struct port*
myPort; and worked as you suggested. But still how come gcc recognizes
struct port* myPort; and not Port* port;. Is it like when struct port*
port; is used the gcc will not bother whether struct port {} is already
included or defined earlier but it is conscious when Port* port; is used.
The same problem i have encountered while using enum like :

 /* in the header file */

enum {IN, OUT, INOUT} MODE;

 /* in the yacc parser file */

%union {

MODE mode; // gave error
enum MODE anotherMode; // gave error

}

Once again thank you very much.

Have good day.

Regards,
Krishna
