R help - Jul 2007 - R CMD SHLIB problem [make: *** No rule to make target ]

Hy all,
 
I apologize for my ingenuity in regard to interfaces in R, but I do need it for
my work. In that respect I took a simple and small example from the net (the
"hello world", one) to interface R with C.
I have a Windows XP OS using R.2.5.0 and in that regard I have installed the
Perl and RTools files to my PC. I also wrote a proper path file, as suggested.
 
The C program is:
 
#include <C:/Archivos de programa/R-2.5.0/include/R.h>
void hello(int *n){
int i;
for(i=0;i<*n;i++){
 Rprintf("Hello, world!\n");
}
}
 
However when trying to compile the a C file in the command window:
 
R CMD SHLIB holla.c
 
I get the following message:

make: *** No rule to make target `holla.d', needed by `makeMakedeps'. 
Stop.
 
Can somebody give me a hand on this,
Thanks in advance

Please do *not* use paths in your C code, especially those with spaces in. 
(The rw-FAQ did advise you not to install into a path with spaces in if 
you wanted to do development work.)  The path is not needed for system 
include files (you used <>) and is likely the problem.

And please do not post multiple times.

You don't need R.h, but you do need to declare Rprintf, which is in
<R_ext/Print.h>.  So a more legible version of a correct program would be

% cat holla.c

#include <R_ext/Print.h>

void hello(int *n)
{
     int i;
     for(i = 0; i < *n; i++)
          Rprintf("Hello, world!\n");
}

which you could call by
> dyn.load("holla.dll")
> .C("hello", 10L)
(note the L).

Prof. Ripley,
 
I will follow your suggestion about file spaces. However, as you said the path
declared in the #include row is redundant, so I think the problem did not come
through that.
Meanwhile, after some tries I could compile the file. I just got more attention
to case sensitiveness.
Sorry for the mess.
 
Cheers,
 
Diogo Andre' Alagador
