Unable to install with ruby 2.2.5

I am getting the following output on running 'make'

Hi Aishmita, This may be an issue with your c++ compiler.

Can you please tell me which version you are using? Also, can you please try using the install.sh script present in tools folder of the respository. Thanks

Getting the same compiler error here.

$ g++ --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 8.1.0 (clang-802.0.42)

I'm not so sure this is an issue with the compiler, so much as it's just that a newer version of the compiler started banning some questionable pointer arithmetic which this code happens to be doing.

e.g., if you change this:

        auto dst_str = (char *)(cbytes+8);

To this:

        auto dst_str = (char *)cbytes + 8;

Now you get one less error. The other 3 look like more or less the same thing.

Disclaimer: I don't know if that change I suggested means the same thing on all platforms, and also the library crashes for me after making this change, and I don't know whether that crash is due to this, or just because tensorflow itself is broken.

Ah, this issue is a duplicate of #84.

@aishmita-aggarwal @trejkaz @chrhansen I am incredibly sorry for the delayed response for this.
I couldn't replicate this issue on my machine before and therefore, I couldn't help you out.
I have updated the code to solve this issue and therefore I am closing this issue.
If the issue still persists feel free to reopen this and I will try my best to help you out.
Thanks
