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. Optionally, activate an existing conda environment, e.g. source activate eman-env. Skip this step, if you don't understand this statement. However, if you already use anaconda, you may get package conflicts when you install eman dependencies in the next step. In that case, you need to install eman and its dependencies in its own conda environment and skip the next step, "Install dependencies".

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

4. Install dependencies

   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.

5. Out-of-source builds are recommended, so work in a directory outside of eman2 source (this is generally true, 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 \
                                          -DEMAN_CXX_FLAGS="-D_GLIBCXX_USE_CXX11_ABI=0"  # This flag will be set in cmake with https://github.com/cryoem/eman2/pull/80
   make -j           # "make" should pick up the number of available processors,
   make -j4          # but you may specify the number if you like
   make install
