error variable not declared

hi..
In .h file I have declared

Code:

---

union Uni1{
int a_data;
float b_data;
}UTemp

---

In .cpp I want to access the variables in the union i.e UTemp.a or UTemp.b;

But while compiling error is generated :

Quote:

---

error: a_data has not been declared.

error: a_data has not been declared.

Pls help

Your error must be related to any other thing.
I created the file test.h:

Code:

---

union Uni1{
int a_data;
float b_data;
}UTemp;

---

and the test.cpp:

Code:

---

#include "test.h"
 
int main(int, char**)
{
UTemp.a_data = 10;
UTemp.b_data = 3.5f;
return UTemp.a_data;
}

---

compiled through:
g++ test.cpp

There were no error complains and the a.out output file was correctly generated. You haven't forgot the ';' after UTemp declaration, have you?

Cheers
