Problems compiling sample project for MC52235

ND — Wed, 30 Aug 2006 18:27:28 GMT

Hi,

I have the MC52235 DEMO board, and using codewarrier V6.3 that comes with it, I am trying to compile the free project that demonstrates the TCP stack,from NicheLite (project called coldfire_lite) from freescale web site.

I have tried to build it but got the following error (many times throughout the code):

***** Error received ****

Error : unexpected end of line
(included from:
cstdarg:40
stdarg.h:17
printf.c:9)
stdarg.68k.h line 20 #if __CFM68K__

**** Source ****

#if __STDABI__ || __REGABI__
#define __va_start(parm) (__std(va_list)) (&parm + 1)
#if __CFM68K__
#define va_arg(ap, type) (*(type *)((ap += sizeof(type) + 3U & ~3U) - (sizeof(type) + 3U & ~3U)))
#else
#define va_arg(ap, type) (*(type *)((ap += sizeof(type) + 3U & ~3U) - (sizeof(type))))
#endif
#else
#define __va_start(parm) (__std(va_list)) ((char *)&parm + (sizeof(parm) + (1U) & ~(1U)))
#define va_arg(ap, type) (*(((type *) (ap += sizeof(type))) - 1))
#endif

Anyone any ideas how to solve this?

Thanks

Neil

Hi,

When you are in a define, it just cut and paste the define value until the end of line.

If the define does not fit in one line, you are required to put a "\" at the end of the line to be able to continue at the next line within the same define value.

Code:

  #define va_arg(ap, type) (*(type *)((ap += sizeof(type) \ + 3U & ~3U) - (sizeof(type) + 3U & ~3U)))

Cheers,

Alban.

Can you generate the preprocessor output?
I guess you have some macro conflict, for example a macro like
#define __CFM68K__ /*nothing*/
somewhere else would explain the error message.h.
Also trigraphs are a source of surprising preprocessor error messages, are tri/bi graphs
enabled?

Something has changed in the new 6.3 release of the compiler. Look for the line:

#define __MC68K__

in common.h and add a zero at the end:

#define __MC68K__ 0

We are working on fixing this ASAP.
