Subject: [Rd] R CMD SHLIB error bad value (core2) for -mtune= switch
Message-ID: <1349996161811-4645928.post@n4.nabble.com>

Hi there,

I'm having trouble to compile the R + C/C++ codes for this project from
Yahoo folks on latent factor models: 
https://github.com/yahoo/Latent-Factor-Models#readme

After downloading the package from the site, I could not successfully *make*
the files.

Here is the message: 
======================================================================================
sh-4.1$ make

======================================================================================

I am running cygwin (virtual linux environment on windows) on Windows 7
64bit Professional with Intel core i5 650 @3.20GHz 3.33GHz with 4GB memory
to take advantage of its c/c++ compile capabilities. My R version is R
2.15.1. It looks to me from the files in my src/C folder that  "src/C/util.c
src/C/factor_model_util.c src/C/pagerank.c src/C/hierarchical.c
src/C/factor_model_multicontext.c " have all been complied to their
corresponding *.o files, but not "src/C/factor_model_util2.cpp ".

Here is the makefile contents (You can download them from the link I posted
above):
======================================================================================
all: lib c_funcs

pagerank: src/C/pagerank.c src/C/util.h
	R CMD SHLIB src/C/pagerank.c -o lib/pagerank.so

c_funcs: src/C/util.h src/C/factor_model_util.h src/C/pagerank.c
src/C/util.c src/C/factor_model_util.c src/C/factor_model_util2.cpp
src/C/hierarchical.c src/C/hierarchical.h src/C/factor_model_multicontext.c
	R CMD SHLIB src/C/util.c src/C/factor_model_util.c src/C/pagerank.c
src/C/hierarchical.c src/C/factor_model_multicontext.c
src/C/factor_model_util2.cpp -o lib/c_funcs.so

clean:
	rm -f src/C/*.o src/C/*.so lib/*.so

lib:
	mkdir lib
======================================================================================

Here is the contents of the makevars:
======================================================================================
PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS) -Wall
======================================================================================

I did check my C:\Program Files\R\R-2.15.1\etc\i386\Makeconf file, but could
not figure out why this matters:
bad value (core2) for -mtune= switch


Can someone help or what else do you need to help diagnose the issue here?

Many Thanks!

YI
