rsync - Jan 2005 - Rsync cross-compilation problem

Hi all !

I really appreciate rsync, so that I would like to make a package for the mips 
architecture, but I encounter a problem when trying to cross compile it :

the configure script has been called using the following options :

  --with-gnu-ld \
  --disable-largefiles \
  --with-included-popt \
  --with-rsh=ssh \

And when using the cross compiler, I get the following message :

In file included from rsync.c:23:
rsync.h:360: warning: no semicolon at end of struct or union
rsync.h:360: error: parse error before "inode"
rsync.h:361: error: parse error before "dev"
rsync.h:361: warning: type defaults to `int' in declaration of `dev'
rsync.h:361: warning: data definition has no type or storage class

So I don't know what to do, I have deleted the concerned line but it causes 
problem when compiling some other files.

Has anyone an idea ?

Thanks a lot for your answer.

Best regards, Florian

The problem code is:

struct idev {
        uint64 inode;
        uint64 dev;
};


uint64 is defined by this code earlier in rsync.h:

#if (SIZEOF_LONG == 8) 
#define uint64 unsigned long
#elif (SIZEOF_INT == 8) 
#define uint64 unsigned int
#elif HAVE_LONGLONG
#define uint64 unsigned long long
#else
/* As long as it gets... */
#define uint64 unsigned off_t
#endif


(Note to Wayne - isn't it dangerous to assume that off_t is 64 bits?
 I don't see any diagnostic test for uint64 less than 64 bits, like
 there is for int64 in io.c.)

What values are used by rsync for these tests?  Find out via:

  egrep "SIZEOF|LONGLONG" config.h

Please copy the output into your reply.

If the sizes are not 8 and HAVE_LONGLONG is 0 then it is using
"unsigned off_t" for uint64, and if off_t is a typedef, a modifier
such as unsigned is not allowed.  That could be the source of your
compilation errors.

If HAVE_LONGLONG is 0, look in config.log for  long long  to see why
the test for it failed.  Does your cross compiler really not have it?

Hi all,

Thanks a lot for your help, when defining LONGLON, it works like a charm.

I just cached the value rsync_ac_cv_HAVE_LONGLONG=yes before running the 
configure script. Instead of having rsync_ac_cv_HAVE_LONGLONG=cross.

Thanks for your help, good luck for your wonderful project !

Best regards, Florian
