Hi all Here is the egrep result : egrep "SIZEOF|LONGLONG" build_mipsel/rsync-2.6.3/config.h /* #undef HAVE_LONGLONG */ #define SIZEOF_INT 4 #define SIZEOF_LONG 4 #define SIZEOF_SHORT 2 and the HAVE_LONGLONG config.log result : rsync_cv_HAVE_LONGLONG=cross Is there a problem with this values ? Thanks a lot for your answer Best regards, Florian
