[Rivet] ruvet and osx

[Sabah Salih]

Dear James,
         It is so nice to hear from you. 
Thank you so much for your kind reply.

I just done 

brew tap osx-cross/arm
brew tap osx-cross/avr

brew install arm-gcc-bin

brew install avr-gcc
This look like installing gcc8

Is this what you meant?

   Many Tanks, Sabah.

Hi,

>From a bit of nurdling about on various fora, that error appears to refer to an option that is present for clang, but not gcc.  Clang is the supplied default on mac.  You have installed a separate gcc toolchain via homebrew.  What I can imagine may be happening is that autotools is detecting the system clang and adding options appropriately, but then the g++ command is now calling the gcc from homebrew.  For example, on my own mac I see

        g++ --version
        Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
        Apple LLVM version 9.1.0 (clang-902.0.39.2)
        Target: x86_64-apple-darwin17.7.0

It’s possible you may be able to cure this with some appropriate environment settings like

        export CC=/usr/bin/clang
        export CXX=/usr/bin/clang++

Which would try to force it to use the system clang compiler consistently.  Alternatively, try to point it to your homebrew compiler location.  You may also like to consider removing homebrew as another solution - I don’t know what else it adds for you, but personally I have never found those kinds of packaging systems helpful on a mac precisely because they bring a second toolchain into play that is not always entirely consistent with the system toolchain.

cheers,

James
