Dear all,
I am trying to reproduce the simple example from Peng & Leeuw article
(http://www.biostat.jhsph.edu/~rpeng/docs/interface.pdf) but have multiple
errors which I cannot resolve.
The example file is hello.c:
===
#include <R.h>
void hello(int *n)
{
int i;
for(i=0; i < *n; i++) {
Rprintf("Hello, world!\n");
}
}
===
I try to compile it via
> R CMD SHLIB hello.c
and get this message:
===
gcc-4.0 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -std=gnu99
-no-cpp-precomp -I/Library/Frameworks/R.framework/Resources/include
-I/Library/Frameworks/R.framework/Resources/include/ppc -I/usr/local/include
-fPIC -g -O2 -c hello.c -o hello.o
In file included from hello.c:1:
/Library/Frameworks/R.framework/Resources/include/R.h:31:20: error: stddef.h:
No such file or directory
... (lot more errors)
===
I thought that the error is in "-I/usr/local/include" because I have stddef.h
in /usr/include. So I tried following:
===
> MAKEFLAGS="CPPFLAGS=-I/usr/include" R CMD SHLIB hello.c
gcc-4.0 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -std=gnu99
-no-cpp-precomp -I/Library/Frameworks/R.framework/Resources/include
-I/Library/Frameworks/R.framework/Resources/include/ppc -I/usr/include
-fPIC -g -O2 -c hello.c -o hello.o
In file included from /Library/Frameworks/R.framework/Resources/include/R.h:35,
from hello.c:1:
/usr/include/float.h:8:24: error: no include path in which to search for float.h
... (and lot more errors)
===

How to resolve the problem? Any help will be appreciated.
With best wishes,
