All platforms

Mac OS X, Linux

1. Download and install Anaconda2 or Miniconda2.

2. Checkout EMAN2 code from GitHub:cryoem/eman2.

   cd <some-path-to-keep-eman2-source>
   git clone https://github.com/cryoem/eman2.git

3. Install dependencies. Follow only one of the steps below:

   1. conda install eman-deps -c cryoem -c defaults -c conda-forge

      Listing the channels explicitly can be avoided by specifying them in $HOME/.condarc, see conda documentation for more details, https://conda.io/docs/using/index.html.

   2. If you already use anaconda, you may get package conflicts when you install eman dependencies by following the instructions in the previous step. In that case, you need to install eman and its dependencies in its own conda environment.

      conda create -n eman-env eman-deps -c cryoem -c defaults -c conda-forge
      source activate eman-env

4. Out-of-source builds are recommended, so work in a directory outside of eman2 source (this is a recommended practice in general, not EMAN2-specific). Note cmake, not ccmake . CMake will automatically find the dependencies. If you want to change any of the CMake values, then use cmake-gui or ccmake.

   cd <build-directory>
   rm -f CMakeCache.txt  # This is needed to ensure cmake doesn't have any leftovers from previous runs
   cmake <some-path-to-keep-eman2-source> -DENABLE_CONDA=ON
   make -j           # "make" should pick up the number of available processors,
   make -j4          # but you may specify the number if you like
   make install
