All platforms

The following instructions will work with cmake changes introduced in https://github.com/cryoem/eman2/pull/65.

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.

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>
   export MACOSX_DEPLOYMENT_TARGET=10.7            # only for MacOSX
   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
