R devel - Apr 2008 - R-extension in unix system -- help to locate header files

Hi list,
To call C,  I used to use R-extension in windows but I'm moving to unix
system
because my PC doesn't have enough memory. My C codes requires to include the
following header files:

#include <stdlib.h>
#include <R.h>
#include <Rdefines.h>
#include <Rmath.h>
#include <R_ext/Applic.h>
#include <R_ext/PrtUtil.h>

In windows, I had no problem with it because I set the path for Rtools
and R etc.
But in unix system, these header files call other header files and
they call other
header files... And some files are not in R folders so I have to
manually find them
and give path and it takes for ever. For example,


#include </usr/include/stdlib.h>
#include </gpfs/data/local/linux/R-2.6.2/lib64/R/include/R.h>
#include </gpfs/data/local/linux/R-2.6.2/lib64/R/include/Rmath.h>
#include </gpfs/data/local/linux/R-2.6.2/lib64/R/include/Rdefines.h>
#include </gpfs/data/local/linux/R-2.6.2/lib64/R/include/R_ext/Applic.h>
#include </gpfs/data/local/linux/R-2.6.2/lib64/R/include/R_ext/PrtUtil.h>

but now
<R_ext/Memory.h> calls <stddef.h> and I have to search the whole
directory of my
school computer to find it. Same for other header files...

Is there better way to do it? Or is there any package for unix that
has "all" the
needed header files so that I can download them only once and don't
have to search
for them? I appreciate your help in advance.

You should never give full paths in #include statements.

The search paths for include ('header') files are set by the compiler
and
supplemented by -I flags on the command line.  If your C compiler is 
unable to find <stdlib.h> something is badly wrong, and you need to ask 
your 'unix' advisor for help.  (BTW, these header files are OS-specific,
and some of them will be compiler-specific -- on my Solaris Unix box cc 
and gcc use different versions of some of these headers.)
