g++: error: unrecognized command line option ‘-R’

Hello, while installing cupy using `pip install cupy --no-cache-dir ’ I encounter a problem.

cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ g++ -pthread -shared -B /home/gin/anaconda2/compiler_compat -L/home/gin/anaconda2/lib -Wl,-rpath=/home/gin/anaconda2/lib,–no-as-needed -Wl,-rpath build/temp.linux-x86_64-2.7/cupy/core/core.o -L/usr/local/cuda-8.0/lib64 -L/home/gin/anaconda2/lib -R/usr/local/cuda-8.0/lib64 -lcublas -lcuda -lcudart -lcurand -lnvToolsExt -lpython2.7 -o build/lib.linux-x86_64-2.7/cupy/core/core.so g++: error: unrecognized command line option ‘-R’ error: command ‘g++’ failed with exit status 1

Actually, ‘-R’ should be replace with ‘-Wl,-rpath’ . After replacing ‘-R’ with ‘-Wl,-rpath’, the g++ command can be successfully run.

I don’t know how to change the comman using setuptool.

Here is the whole log.

@hvy Thank you.

Finally, I found that the latest Python 3.6.3 (3.6.3-hc9025b9_1) can successfully install cupy without downgrading.

After dozens of testing, I figured out that compatibility libraries provided by Anaconda 3 is the culprit. Unfortunately, anaconda-flavored libraries causing havocs has happened many times before, such as this and this. I tried to update gcc and other binaries but it didn’t work either. I suggest everyone to just use plain python installations or virtualenvs not based on conda to work around the problem.
