All platforms
The following instructions will work with cmake changes introduced in https://github.com/cryoem/eman2/pull/65.
Mac OS X, Linux
Download and install Anaconda2 or Miniconda2.
Checkout EMAN2 code from GitHub:cryoem/eman2.
cd <some-path-to-keep-eman2-source> git clone https://github.com/cryoem/eman2.git
Optionally, activate an existing conda environment, e.g. source activate eman-env. Skip this step, if you don't understand this statement.
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.
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 the number of available processors, make -j4 # but you may specify the number if you like make install
