Meaning of Cosmic's segment .bss size overflow error

''The page 9 reference (I had read it) escaped my understanding as to its ability to discern the Cosmic compiler.''

 

It seems pretty clear to me - in what way would you have it changed?

''Perhaps a mention could be included in the manual?''

Which manual do you mean?

Since the Standard Peripheral Library supports both Cosmic & Raisonance compilers, its source code would seem like an obvious place to look to see how it distinguishes the two; eg, in stm8s.h:

 

/******************************************************************************/

/*                   Library configuration section                            */

/******************************************************************************/

/* Check the used compiler */

#if defined(__CSMC__)

 #undef _RAISONANCE_

 #define _COSMIC_

 

 #define TINY @tiny

 #define NEAR @near

#elif defined(__RCST7__)

 #undef _COSMIC_

 #define _RAISONANCE_

 #define TINY page0

 #define NEAR data

#else

 #error ''Unsupported Compiler!''          /* Compiler defines not found */

#endif

Thank you, and succinct. 

The page 9 reference (I had read it) escaped my understanding as to its ability to discern the Cosmic compiler.  Perhaps a mention could be included in the manual?

Hi,

1744 is the size of the overflow, that is, the difference between the actual size of the segment and its maximum size (as specified by the -m parameter for that segment, in the linker file)

As for your other question, I quote the user manual, page 9:

The COSMIC compiler defines the __CSMC__ preprocessor symbol....

Regards,

Luca

PS: note that when you have a linker error the map file is NOT created.
