Motorola MPC5200 Manuel D’Utilisation

KADAK has successfully used the BestComm API and firmware source code without
modification using the Metrowerks software development tools.  All modules have been
successfully compiled without warnings or errors.

However, when the BestComm source code is compiled using the Diab (Wind River) or
MetaWare tools, numerous warnings and some errors are encountered.  KADAK has
made no attempt to review or repair the source code which generated warnings.
However, many years of experience with these tools have proven that it is not wise to
ignore the warnings and Freescale should be encouraged to review the source code.

The errors occur because of the use of the non-ANSI C keyword 

 in header file

.  This keyword is not supported by either Diab or MetaWare compilers.

To avoid the errors when using these tools, KADAK has inserted the following code
fragment near the beginning of header file 

:

Symbol 

, if required, is defined on the command line used to invoke the

compiler in tailoring file 

.

If the compiler supports an alternate keyword for an in-line function, symbol 

is defined to be that keyword.  For example, the tailoring file for MetaWare tools defines

 to be 

, the equivalent MetaWare keyword.

If the compiler does not support in-line functions, symbol 

 must be defined to

be an empty string.  For example, the tailoring file for Diab tools defines 

 but

does not specify a value for the symbol, since it does not support the feature.

If the compiler supports the 

 keyword, symbol 

 must not be defined.

Note

No improper operation of the BestComm API and
microcode has been observed as a consequence of this code
patch.  Note that the BestComm software compiled in this
fashion has been exercised using the FEC subsystem only.
