Got it now, thanks! Are you planning to publish the build scripts for
the new Rtools as well?
I did the following limited test on the new Rtools:
R CMD INSTALL --no-multiarch Rcpp_0.11.5.tar.gz
I did this under various settings:
- the default settings
- with -std=c++11 added to CXXFLAGS in my .R\Makevars file.
This was done under the newly released R-3.1.3, using the 64-bit R binary.
Here are my findings:
- With the default settings, the command succeeded
- With -std=c++11, there were two problems:
+ api.cpp failed to compile because it could not find execinfo.h
* I worked around this by using CXXFLAGS=-DWIN32 -std=c++11
* CXXFLAGS=-std=gnu++11 also works around this
* Maybe Rcpp needs to guard against this?
+ the package could not be loaded because some of the object files
contain symbols named .refptr.* and .weak.*, which should be excluded
from the exports list
* To work around this, put this line in .R\Makevars: NM_FILTER = |
sed -e '/\.refptr\./d; /\.weak\./d'
