Odd Compiler Error_

vining · January 2012

DEFINE_VARIABLE
VOLATILE CHAR cTX_Queue[HVAC_ZONES * 128] ;
or
DEFINE_VARIABLE
VOLATILE CHAR cTX_Queue[HVAC_ZONES * 64] ;

results in this:

ERROR: file\path...... C10219: Array [CTX_QUEUE] must have an initializer if bounds are not specified

While the same thing with a number from 1-63 or 65-127 or 129-256 compiles just fine. I didn't actually try every number but everything I did try other than 64 or 128 did work.

HVAC_ZONES is an integer constant of 4.

I don't have it open and set up to test, but memory tells me that you aren't allowed to do variable or constant math inside a variable declaration. I think it does allow direct numeric math though.

Edit: I re-read your post and now understand what you are saying... it was the number and not the constant that it didn't like. That's pretty weird!

Looks like you found some sort of bug.

You can change HVAC_ZONES and/or your multiplier to any numbers but if when you multiply the two and the result is a multiple of 256 the compiler chokes. If it's not a multiple of 256 the compiler is happy.

Odd...

Odd. As in, make HVAC_ZONES an odd number.

try this,

DEFINE_VARIABLE
VOLATILE CHAR cTX_Queue[(HVAC_ZONES * 128) + (256 - 256)] ;

and it will compile.

Did they have a theory behing that? In this instance it's easier to make the queue large or smaller since it does't really matter but let them play with this:

The above compiles fine including the last 3 constants but this next line doesn't:

HWI_TOTAL_OUTPUTS		= (HWI_TOTAL_MI_OUTPUTS + HWI_TOTAL_H48_OUTPUTS + HWI_TOTAL_RF_OUTPUTS) ;

The compiler throws this error:

ERROR: C:\filepath...\Netinx_Code\VAV_HWI.axi(98): C10539: Identifier [HWI_TOTAL_MI_OUTPUTS] undefined

So I just comment it out and use:

HWI_TOTAL_OUTPUTS		= 160 ;

Obviously it defeats the prupose of going through all this crap.

If they figure it out I'll buy them ein bier at the next Kieler Woche. Actually not since I don't drink anymore and I won't be going to Kiel. The idea is very tempting though.

Hmmm, i'll have to see what i'm running and update.

Thanks for checking it.

vining · January 2012

Turns out I was running build 3.2.0.418 which is newer and I went ahead and updated to the current version 3.3.525.

Still didn't work on my system so I started playing around.

This worked:

HWI_TOTAL_OUTPUTS_		= ((HWI1_NUM_MIs * HWI_NUM_MI_DEVICES) + (HWI2_NUM_MIs * HWI_NUM_MI_DEVICES) + (HWI3_NUM_MIs * HWI_NUM_MI_DEVICES)
				   + (HWI1_NUM_H48s * HWI_NUM_H48_DEVICES) + (HWI2_NUM_H48s * HWI_NUM_H48_DEVICES) + (HWI3_NUM_H48s * HWI_NUM_H48_DEVICES)
				   + (HWI1_NUM_RF_LINKS * HWI_NUM_RF_DEVICES) + (HWI2_NUM_RF_LINKS * HWI_NUM_RF_DEVICES) + (HWI3_NUM_RF_LINKS * HWI_NUM_RF_DEVICES))

and then this worked:

HWI_TOTAL_SW_DIM 		= (HWI_TOTAL_MI_OUTPUTS + HWI_TOTAL_H48_OUTPUTS + HWI_TOTAL_RF_OUTPUTS) ;

so I thought WTF! I then figured maybe because these constants that worked weren't actually used in any later declarations so I went to the first place the non working constant was used and changed it to a working constant:

CHAR HWI_OUTPUT_NAMES[HWI_TOTAL_SW_DIM ][18]=

but that didn't break the constant now that is was actually used but I didn't give up and stepped through the code and changed where HWI_TOTAL_OUTPUTS was used one at a time and it turns out that it breaks here.

DEFINE_TYPE     //_sHWI

STRUCTURE _sHWI

     {
     _sHWI_Status sStatus ;
     _sHWI_Outputs sOutput[HWI_TOTAL_OUTPUTS] ;//
  }

if I change that to a constant declared with out a constant used with a math operation it works but if I use a constant declared using a constant and a math operation it doesn't.

This works:
TEST_CONSTANT 			= 40 ;
_sHWI_Outputs sOutput[TEST_CONSTANT] ;

This works:
TEST_CONSTANT 			= (10 * 40) ;
_sHWI_Outputs sOutput[TEST_CONSTANT] ;

This doesn't:
HWI_SOME_DUMB_NUM		= 20 ;
TEST_CONSTANT 			= (HWI_SOME_DUMB_NUM * 40) ;
_sHWI_Outputs sOutput[TEST_CONSTANT] ;

Using HWI_TOTAL_OUTPUTS everywhere else in the code works fine but not in the structure "type" declarations. This is an old issue that I gave up on long ago so it doesn't bother me.

HWI_TOTAL_MI_OUTPUTS		= ((HWI1_NUM_MIs * HWI_NUM_MI_DEVICES) + (HWI2_NUM_MIs * HWI_NUM_MI_DEVICES) + (HWI3_NUM_MIs * HWI_NUM_MI_DEVICES)) ;
HWI_TOTAL_H48_OUTPUTS		= ((HWI1_NUM_H48s * HWI_NUM_H48_DEVICES) + (HWI2_NUM_H48s * HWI_NUM_H48_DEVICES) + (HWI3_NUM_H48s * HWI_NUM_H48_DEVICES)) ;
HWI_TOTAL_RF_OUTPUTS		= ((HWI1_NUM_RF_LINKS * HWI_NUM_RF_DEVICES) + (HWI2_NUM_RF_LINKS * HWI_NUM_RF_DEVICES) + (HWI3_NUM_RF_LINKS * HWI_NUM_RF_DEVICES)) ;

HWI_TOTAL_OUTPUTS 		= (HWI_TOTAL_MI_OUTPUTS + HWI_TOTAL_H48_OUTPUTS + HWI_TOTAL_RF_OUTPUTS) ;

like:
if(sHWI_UI[iUI_Indx].nSelOut && sHWI_UI[iUI_Indx].nSelOut <= HWI_TOTAL_OUTPUTS)
