error: member reference base type 'int' is not a structure or union

[alon9669]

I define a structure

typedef struct
{
 char g_sUDP_HostAddress[MAX_ADDRESS_LEN];
 char g_sUDP_ClientAddress[MAX_ADDRESS_LEN];
 int g_iUDP_ReadPort;
 int g_iUDP_WritePort;
 double g_dMaxCurrentComsumption_A;
 double g_dOperatingVoltage_V; 
 int g_iPSU1TestWaitTime;
 double g_dTestVoltage_33V;
 double g_dTestVoltage_16V;
 int g_iRLY3152TestWaitTime;
 int g_iRLY2114TestWaitTime;
 int g_iRLY2662TestWaitTime;
 double g_dAIO1OutputVoltage_V;
 double g_dAIO1InputVoltage_V;
 int g_iAIO1TestWaitTime;
 int g_iDIO1TestWaitTime;
 int g_iAIO1LogicOutputVoltage_V;
 int g_iCATALYSTTestWaitTime;

} Test_Parameter_t;

Test_Parameter_t Test_Parameter;

In another file I pass a member of the structure as an argument 

extern Test_Parameter;

SetVoltage ( Test_Parameter.g_dOperatingVoltage_V );

While compiling I get an error:

error: member reference base type 'int' is not a structure or union

How do I fix the problem?

Hi,

with

extern Test_Parameter;

you are declaring an int with name Test_Parameter and external linkage.

You need to add the type:

extern Test_Parameter_t Test_Parameter;
