phyx requires a few dependencies. Since installation of these dependencies differs on Linux vs. Mac OSX, we've separated the instructions below.

Mac has become increasingly difficult to support at the command line with changes every version on location and standards for compilation tools. First, distribution of compiled programs is very difficult. Furthermore, Mac now defaults to clang as a C/C++ compiler, which does not support OpenMP. For Mac OSX 10.12, we have found that you can install with clang using the simple instructions and [homebrew] (http://brew.sh/) or using a fresh installation of gcc from here. Instructions for both are below (don't use both, choose one, probably the simple one). For simple instructions click here, and for advanced instructions click here.

The instructions below assume homebrew, which is convenient for dealing with dependencies.

1. Install the homebrew package manager:

    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
   

2. Install dependencies from homebrew:

    brew install git
    brew install cmake
    brew install nlopt
   

3. On to phyx. first, clone the repository (if you haven't already):

    git clone https://github.com/FePhyFoFum/phyx.git
   

4. Install the final dependency, armadillo, (included with phyx). You can do this with the included files or with homebrew:

    brew install armadillo
   

   or

    cd phyx/deps
    tar -xzf armadillo-7.400.2.tgz
    cd armadillo-7.400.2
    ./configure
    make
    sudo make install
   

5. Add the necessary bits to .bash_profile. At the end of .bash_profile add these lines (this is for home-brew):

    export CPPFLAGS='-I/usr/local/include'
    export LDFLAGS='-L/usr/local/lib'
   

6. Install phyx

    cd ../../src
    ./configure
    make
    python run_tests.py
   

   If you want to install it so it is available anywhere in your system, do:

    sudo make install
   

1. Install gcc and gfortran. Download gcc-6.2-bin.tar.gz or more recent from http://hpc.sourceforge.net/. Install with:

    sudo tar -xvf gcc-6.2-bin.tar -C /
   

2. Install autoconf from http://ftp.gnu.org/gnu/autoconf/. Get autoconf-latest.tar.gz, then:

    tar -xzf autoconf-latest.tar.gz
    cd autoconf-2.69
    ./configure --prefix=/usr/local/autoconf-2.69
    make
    sudo make install
    ln -s autoconf-2.69 /usr/local/autoconf
   

3. On to phyx. first, clone the repository (if you haven't already):

    git clone https://github.com/FePhyFoFum/phyx.git
   

4. Install cmake and install Armadillo. Get cmake from https://cmake.org/download/. I got https://cmake.org/files/v3.6/cmake-3.6.2-Darwin-x86_64.tar.gz. Get armadillo from the deps directory or http://arma.sourceforge.net/download.html, get the stable one. Untar it. Double click the Cmake.app. Click "Browse source..." and choose the armadillo folder that was created after untaring. Click "Browse build..." and choose the same folder as browse source. Click "Configure" and then click "Generate". Go to the terminal and browse to that armadillo folder and type:

    make
    sudo make install
   

5. Install nlopt. Get armadillo from the deps directory or go to http://ab-initio.mit.edu/wiki/index.php/NLopt#Download_and_installation and download the latest (probably nlopt-2.4.2.tar.gz). Untar and browse in the terminal to that directory:

    ./configure --without-octave --without-matlab
    make
    sudo make install
   

6. Compile phyx. Now you can go to the src directory of phyx and type:

    ./configure
    make
    python run_tests.py
    sudo make install
   

   and all the programs should compile without issue.

These instructions work for most ubuntu versions as well as debian.

1. Install general dependencies:

    sudo apt-get install git autotools-dev autoconf automake cmake libtool liblapack-dev libatlas-cpp-0.6-dev libnlopt-dev libnlopt0
   

2. Clone the phyx repo (if you haven't already):

    git clone https://github.com/FePhyFoFum/phyx.git
   

3. Install armadillo dependency
   Note: it is possible to get from apt-get, but need version >= 5.2:

    sudo apt-get install libarmadillo-dev
   

   On debian it was necessary to use backports:

    sudo apt-get -t jessie-backports install libarmadillo-dev
   

   If that is not possible, compile the provided code:

    cd phyx/deps
    tar -xvzf armadillo-7.400.2.tgz
    cd armadillo-7.400.2
    ./configure
    make
    sudo make install
   

4. Finally, install phyx:

    cd phyx/src
    ./configure
    make
    python run_tests.py
   

   If you want to install it so it is available anywhere in your system, do:

    sudo make install
