Now, I have to confess that I've only recently come out of the dark ages of the FS700 and FS800 macros and started using the FS900 macro. I've yet to run headlong into the serialization of the FS1000 macro (later, later  ).

 

I'm getting a redefinition warning when compiling two gauges:

 

Macro definitions:-

 

 

FAILURE_RECORD cpc_fail[] =
{
        {FAIL_NONE, FAIL_ACTION_NONE}
};

#define     GAUGE_NAME          "cpc\0"
#define     GAUGEHDR_VAR_NAME   gaugehdr_cpc
#define     GAUGE_W             20

#include "flighteng\dfd_cpc.cpp"

FAILURE_RECORD ecs_fail[] =
{
        {FAIL_NONE, FAIL_ACTION_NONE}
};

#define     GAUGE_NAME          "ecs\0"
#define     GAUGEHDR_VAR_NAME   gaugehdr_ecs
#define     GAUGE_W             20

#include "flighteng\dfd_ecs.cpp"

 

 

Warnings:-

 

1>xxxxxxxxxxxxxx.cpp(1265): warning C4005: 'GAUGE_NAME' : macro redefinition
1>          xxxxxxxxxxxxxx.cpp(1254) : see previous definition of 'GAUGE_NAME'
1>xxxxxxxxxxxxxx.cpp(1266): warning C4005: 'GAUGEHDR_VAR_NAME' : macro redefinition
1>          xxxxxxxxxxxxxx.cpp(1255) : see previous definition of 'GAUGEHDR_VAR_NAME'

 

 

I agree that the warning is pretty explicit and I suspect that it is something to do with the FS900 header structure:

 

 

GAUGE_HEADER_FS900(gaugehdr_cpc,GAUGE_W, cpc_gauge_name, &cpc_list, cpc_mouse_rect, cpc_update, 0,0);

 

 

Would someone be kind enough to tell me what I need to change to suppress the warnings? I gave up after thirty or so minutes!

You need to #undef the macros after each sub-gauge:

 

#define     GAUGE_NAME          "cpc\0"
#define     GAUGEHDR_VAR_NAME   gaugehdr_cpc
#define     GAUGE_W             20

#include "flighteng\dfd_cpc.cpp"

 

#undef     GAUGE_NAME

#undef     GAUGEHDR_VAR_NAME

#undef     GAUGE_W   //for completeness only, seeing as you're using the same value again

Thanks Doug. The #undef statement in the gauge.c/.cpp file worked fine for FS700 and FS800, so it never occurred to me that it might night work for the later versions. Of course, now I have your answer it's d*mned obvious!!! :lol:
