Error: Missing Right Brace

[Doglao 0]

Hi!

I make a attempt to put a structure in a class and then shows this error message "missing right brace".

are not accepted structures as member of class?

thanks!

 

class Cmcp23016{

public:

Cmcp23016();

Cmcp23016(int);

~Cmcp23016();

void WriteMcp23016(int iSlaveAddr, int iCommandByte, int iLsb, int iMsb);

void LeMcp23016(int iSlaveAddr, int iCommandByte);

void config_mcp(int slave);

private:

int m_iVarGp0;//varialvel do byte baixo do mcp23016

int m_iVarGp1;//varialvel do byte alto do mcp23016

struct DoisBytes{// the message error highlighting this line

unsigned char iLsb;

unsigned char iMsb;

};

union Converse

{

int Gp;

struct DoisBytes Gp0e1;

}Totaliza;

 

};

class Cmcp23016{
...
struct DoisBytes{
	unsigned char iLsb;
	unsigned char iMsb;
} v;   // <--- you need to have a variable name here !!!
...
};

Pavel

thank you a lot Mr. Pavel, this works fine now, but I have to put the struct on inside the union to take the effect that I hope, is this a BoostC++ limitation or a normal behavior of C++ ?
