This looks like a CR/LF problem. AFAIK, the GCC preprocessor isn't
always too happy about text files that end with CR/LF.
Try to remove the CR's and compile again.

Yes you were right, it was the CR/LF problem. I have now wrote a tcl script
that converts all files from dos2unix format.

Thanks!

[ECOS] Macro problem with gcc and eCos

[Daniel.Andersson]

Hi,

I have problems when I compile my application together with eCos
using gcc for ARM. When I try to compile the code section with 
VC++ it works without problem.

The eCos code I got problem with looks like this:

------snip--------
#define CYG_MACRO_START do{
#define CYG_MACRO_END   }while (0)

#define CYG_EMPTY_STATEMENT CYG_MACRO_START CYG_MACRO_END

#define CYG_UNUSED_PARAM( _type_, _name_ ) CYG_MACRO_START      \
  _type_ __tmp1 = (_name_);                                     \
  _type_ __tmp2 = __tmp1;                                       \
  __tmp1 = __tmp2;                                              \
CYG_MACRO_END
-------end snip----


It gives me the following error:

------snip--------
arm-elf-gcc -mcpu=arm7tdmi                         -c -o twothreads.o -g
-Wall -I/ecos-work/include -ffunct
ion-sections -fdata-sections  twothreads.c
In file included from /ecos-work/include/cyg/kernel/kapi.h:53,
                 from twothreads.c:1:
/ecos-work/include/cyg/infra/cyg_type.h:169: parse error before `__tmp1'
/ecos-work/include/cyg/infra/cyg_type.h:169: warning: type defaults to `int'
in declaration of `__tmp1'
/ecos-work/include/cyg/infra/cyg_type.h:169: `_name_' undeclared here (not
in a function)
/ecos-work/include/cyg/infra/cyg_type.h:169: warning: data definition has no
type or storage class
-------end snip----

Does anyone know what the problem is?
