Hi Laurent,
Apologies if this is a bit curt/blunt - I'm running late and just
squeezed in an attempt to build rpy2 (from the zip file for 2.1.0rc)
before going home. It is mostly a list of questions I'm afraid.
I've just tied to build it using the MS compiler under Python 2.6 (a
setup I know can build other Python packages with C code), and failed.
First attempt:
C:\Downloads\rpy2-2.1.0rc>c:\python26\python setup.py bdist_wininst
c:\python26\lib\distutils\dist.py:266: UserWarning: Unknown distribution option:
'install_requires'
warnings.warn(msg)
running bdist_wininst
running build
running build_py
running build_ext
Error: Tried to guess R's HOME but no R command in the PATH.
What is this install_requires warning about?
Why isn't rpy2 checking the registry to find R (a regression from rpy1)?
How do I tell it where I have R installed (other than via the PATH)?
>From looking at setup.py there is something about this.
I updated my PATH to include "C:\Program Files\R\R-2.10.1\bin" and
tried again, and got further (this is the output from the second run -
same error but without all the noise):
C:\Downloads\rpy2-2.1.0rc>c:\python26\python setup.py bdist_wininst
c:\python26\lib\distutils\dist.py:266: UserWarning: Unknown distribution option:

Note this gives sane output:
C:\Downloads\rpy2-2.1.0rc>R CMD config
Usage: R CMD config [options] [VAR]
Get the value of a basic R configure variable VAR which must be among
those listed in the 'Variables' section below, or the header and
library flags necessary for linking against R.
Options:
-h, --help print short help message and exit
-v, --version print version info and exit
--cppflags print pre-processor flags required to compile
a program using R as a library
--ldflags print linker flags needed for linking against
the R library
Variables:

CC C compiler command
CFLAGS C compiler flags
CPICFLAGS special flags for compiling C code to be turned into a
shared library
CPP C preprocessor

headers in a nonstandard directory <dir>
CXX C++ compiler command
CXXCPP C++ preprocessor
CXXFLAGS C++ compiler flags
CXXPICFLAGS special flags for compiling C++ code to be turned into a
shared library

MAKE Make command
SAFE_FFLAGS Safe (as conformant as possible) Fortran 77 compiler flags
SHLIB_CFLAGS additional CFLAGS used when building shared objects
SHLIB_CXXLD command for linking shared objects which contain
object files from a C++ compiler
SHLIB_CXXLDFLAGS
special flags used by SHLIB_CXXLD
SHLIB_EXT file extension (including '.') for shared objects
SHLIB_FFLAGS additional FFLAGS used when building shared objects

TCLTK_CPPFLAGS
flags needed for finding the tcl.h and tk.h headers

However, including the --cppflags flag makes things go a bit odd:
C:\Downloads\rpy2-2.1.0rc>R CMD config --cppflags
/cygdrive/c/PROGRA~1/R/R-210~1.1/bin/config.sh: line 143: make:
command not found
/cygdrive/c/PROGRA~1/R/R-210~1.1/bin/config.sh: line 144: make:
command not found
R was not built as a library
Note that there really is a file "C:\Program
Files\R\R-2.10.1\bin\config.sh" and it may be possible to get it to
run on my machine since I have cygwin. I get the same with R-2.9.2 and
R-2.8.2. Just in case it was the problem, I edited my PATH again to
remove C:\cygwin\bin\;C:\cygwin\usr\bin\; and retried, but R acts the
same way.
However, ignoring that, it claims my R installs were not built as libraries (?).
I wonder if this is a Windows specific bug in the config support in
recent versions of R?
What was the last version of R known to work with rpy2 on Windows XP 32 bit?

Peter
