macos cmake fpu_control problem

[wheelBL]

My system is macOS 10.13.3. When I execute cmake .. in folder ApproxMVBB/Build It generated two errors and I paste them below. I searched google found that fpu_control.h is not a macOS header. So how do I build it? Thank you!

Could you send me the whole output text based and post it here? I have one Apple macOS build. I develop on macOs, (not Sierra). The latest release from yesterday, might still have some problems, since I changed everything to a modern cmake...

Ok. This is the result of executing cmake command.

Thanks. And do you need other files or information?

Ok, I did not yet properly add AppleClang to the CmakeBuild... I will correct that, today or tomorrot. In the meanwhile you can try to compile with gcc on macOS. brew install gcc7.0 -> make sure to put somthing like the following into your ~/.bash_profile

comp="gcc@7.0"
if [[ ${comp} == "clang" ]] ; then
    echo "enabling clang7.0"
    export PATH="/usr/local/opt/llvm/bin:$PATH"
    export CC="/usr/local/opt/llvm/bin/clang"
    export CXX="${CC}++"
    export LDFLAGS="-L/usr/local/opt/llvm/lib -Wl,-rpath,/usr/local/opt/llvm/lib"
    export CPPFLAGS="-I/usr/local/opt/llvm/include -I/usr/local/opt/llvm/include/c++/v1/"
    export CXXFLAGS="$CPPFLAGS"
elif [[ ${comp} == "gcc@7.0" ]] ; then
    echo "enabling gcc@7.0"
    export PATH="/usr/local/opt/$comp/bin:$PATH"
    export CC="/usr/local/opt/$comp/bin/gcc-7"
    export CXX="/usr/local/opt/$comp/bin/g++-7"
    export LDFLAGS="-L/usr/local/opt/$comp/lib/gcc/7 -Wl,-rpath,/usr/local/opt/$comp/lib/gcc/7"
    export CPPFLAGS="-I/usr/local/opt/$comp/include -I/usr/local/opt/$comp/include/c++/7.2.0"
  export CXXFLAGS="$CPPFLAGS"
elif [[ ${comp} == "gcc@4.9" ]] ; then
    echo "enabling gcc@4.9"
    export PATH="/usr/local/opt/$comp/bin:$PATH"
    export CC="/usr/local/opt/$comp/bin/gcc-4.9"
    export CXX="/usr/local/opt/$comp/bin/g++-4.9"
    export LDFLAGS="-L/usr/local/opt/$comp/lib/gcc/4.9 -Wl,-rpath,/usr/local/opt/$comp/lib/gcc/4.9"
    export CPPFLAGS="-I/usr/local/opt/$comp/include -I/usr/local/opt/$comp/include/c++/4.9.4/"
    export CXXFLAGS="$CPPFLAGS"
fi

Thanks a lot! It works. But there was a flaw in it for my system. comp should be "gcc@7"

Ah ok really, strange for me its 7.0 lol, thanks for the update. But its weird why it does not work for AppleClang... I will look in to that, strange because travis builds it with AppleClang as far as I saw ;)
