Installation complains about incompatibility when using Python 2.7.11

Hi, I have trouble installing rPython. I'm using python 2.7.11 and R 3.2.3 on Windows 7 enterprise (64-bit). I used Rtools33 to do the isntall.

Here's the log I got:

• installing source package 'rPython' ... ** libs Warning: this package has a non-empty 'configure.win' file, so building only the main architecture

Did you follow all the installation steps as indicated in the package page in Github? In the logs I see that you cannot find a library and you should:

1. have it
2. indicate where to find it in the required configuration script.

Unfortunately, it is very difficult to know where R should go and look for Python dependencies in Windows, so users need to do it themselves.

Hello, Sadly I have the same problem with python35. I found the lib and adapted the paths in the configure.win file :

echo 'PKG_LIBS=-LC:/Users/mli/AppData/Local/Programs/Python/Python35-32/libs -lpython35'  > src/makevars.win
echo 'PKG_CFLAGS=-I"C:/Users/mli/AppData/Local/Programs/Python/Python35-32/include"'     >> src/makevars.win

I get this error

cannot find -lpython35
collect2: ld returned 1 exit status

Thank you for doind this work, Cheers

Hi, this configure.win file made it for me

   echo 'PKG_LIBS=-LC:/python35/libs -lpython35'  > src/makevars.win
   echo 'PKG_CFLAGS=-I"C:/Python35/include"'     >> src/makevars.win
