| Maximum number of global bits? |

This post is an extension of an earlier post: http://www.ccsinfo.com/forum/viewtopic.php?t=34506
I have managed to code around the previous post's bug painfully, by not adding any new defines for months. Until now, as long as I do not add a #define I can keep adding and revising code. Painful!
I'm using PCH version 4.071 with a PIC18F8722 target on a gigantic (126768 bytes ROM used) application. The program is comprised of 20 header files and 18 C files. I am awaiting my 4.076 upgrade key.
Déjà vu - We start with a working, compiling program, that is error free. Then I add one new global bit:
| Code: | | int1 gbIrDAMasked = false; |
I get an error
| Quote: | | Error 53 "C:\Devel\PIC-C\Atlanta\Atlanta-Mode.c" Line 49(1,8): Expecting function name |
The error refers to a completely different system, and does not look like an error to me (and remember, it compiled before we added the new definition). Here is Line 49 from the referenced file:
| Code: | | fprintf(TERM,"Toggle reverse valve"); |
When I simply remark the new global bit out of the code, the project once again compiles successfully.
Again, to cover the bases, I have tried:
* moving the global bit to a different location of the header file
* changing the variable name
* putting it in another header file
In all cases the project will not compile, reports the same error, until I remove this extra global bit.
Like the previous post, since it does not have to do with the name, the value, or the location, I now have to wonder if there is a maximum number of global bits one can define in PCH? I think it is either that or we are hitting the roof on the capabilities of the CCS compiler itself.
Since I know I'll be asked, here is the entire small header file that contains the new bit: | Code: | ///////// IrDA Interface Header File/////////
// Program Value Definitions
#define IRDA_I_BUFFER_SIZE 255 // IrDA input buffer size
#define IRDA_PORT 2 // The serial port # for IRDA
///////////// Includes /////////////
#include "Dev-AT24C1024.c" // I2C EEPROM Device Interface
#include "STDLIBM.h" // Memory Handling Header File
///////////// Shared Variables /////////////
int1 gbIrDAMasked = false; |
And here is the whole subroutine that fails when I add a new global bit:
| Code: | //--------------------------------------------------------------------------
// Toggle the reversing valve.
//
void AtlMode_Reverse(void) {
if(giRunMode == RUN_TEST) {
gsTestState.bRev = !gsTestState.bRev; // Toggle the reversing valve
if(gsTestState.bRev) {
if(gsTestState.iStage > gsSetting.iNumStages) gsTestState.iStage = gsSetting.iNumStages;
}
fprintf(TERM,"Toggle reverse valve");
AtlTerm_CRLF();
}
return;
} |
Once again, thanks in advance!

Yay, after a while I received my 4.076 upgrade key, the bug went away. Everything compiles "as-is", with no errors, with the new bit, with no other changes, on 4.076.
(Now I will see if I can add some new #define statements too...)
