Compiling EMAN2 on Mac OS X with Homebrew

Homebrew is a package management system for Mac. It is under active development and has strict policies to protect the user from damage via software. They also seek to protect users from themselves by avoiding sudo commands as much as possible. It is recommended that you do NOT install homebrew alongside other package managers such as macports/fink.

The following install was successful on OS X 10.8 (Mountain Lion) and OS X 10.10 (Yosemite) and 10.11 (El Capitan). If for any reason this doesn't work for you, I recommend refreshing your terminal (1st) and restarting your computer (2nd) since many of the packages downloaded might require sourcing. If neither solve your specific problem, please send an e-mail to a member of the lab and we'll try to address it as soon as possible. Also, it may be necessary to turn off SIP (System Integrity Protection) before proceeding when installing on El Capitan. To do this, reboot your machine while holding [CMD]+[R], open a terminal from the utilities menu at the top of the screen, type "csrutil disable", hit enter, type reboot, and hit enter to restart with SIP disabled.

Additionally, a known problem of using pure homebrew is that Qt windows seem to possess abnormally large buttons. A way around this is to install Qt/PyQt from source.

Install homebrew

To install homebrew, simply paste the following line into your favorite Mac terminal emulator:

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

To make sure everything is up to date, run:

brew update

To make sure everything is configured correctly, run the following command, addressing any warnings or errors before proceeding. Most of the warnings can be ignored, but for the smoothest install, it is better to address them sooner rather than later.

brew doctor

Additionally, add the following to your shell's 'rc' file to source homebrew programs ahead of the system's default versions:

export PATH=/usr/local/bin:$PATH

If you find you have already completed these instructions but are upgrading from OS X 10.8, 10.9, or 10.10, you will need to reinstall all homebrew packages or start from scratch. Luckily, there is an easy way to do the former:

brew list | xargs brew reinstall -v

This should reinstall all packages in their current versions.

Required Packages

Xcode

Starting with Mac OS X 10.7 and Xcode 4.3, the developer tools are distributed through the Mac App Store instead of an installer package.

You'll also need the command line tools, which you can install with:

xcode-select --install

CMake

CMake is a family of tools designed to build, test and package software. It is used to generate the Makefiles for compiling EMAN2. We install the homebrew version as follows:

brew install cmake

Qt4

Qt is a graphics library for cross-platform user interfaces.

brew install qt --with-developer --with-docs --HEAD

Boost

Boost is a set of useful, standardized libraries for C++. It is used to generate the Python-C++ interface in EMAN2. Homebrew comes with two 'boost' packages, and we'll need both to generate the libraries required for compiling EMAN2:

brew install boost --with-python
brew install boost-python

To install with MPI support, simply run the following commands instead:

brew install boost --with-mpi --with-python
brew install boost-python

GSL

The GNU Scientific Library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting.

brew install gsl

A personal concern is that there is no option to '--enable-float'; however, I have not run into any problems with this yet.

FFTW3

FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST). The most recent version is available from homebrew as follows:

brew install fftw

Berkeley DB (5.3.28)

The Oracle Berkeley DB family of open source, embeddable databases provides developers with fast, reliable, local persistence with zero administration. EMAN2 uses Berkeley DB as a mechanism for local storage of project metadata.

Oracle has made their most recent version very VERY proprietary. To install BDB, you need an account on the following website at which you can download BDB 5.3.28.

http://www.oracle.com/technetwork/database/database-technologies/berkeleydb/downloads/index-082944.html

Once there, download "Berkeley_DB_5.3.28.tar.gz," then enter the following commands where you placed the download (preferably your source code directory).

tar -xzf db-5.3.28
cd db-5.3.28/build_unix
../../dist/configure
make
sudo make install

If you encounter errors during this process, I suggest trying the following:

cd db-5.3.28
cd src/dbinc
curl -O https://raw.githubusercontent.com/narkoleptik/os-x-berkeleydb-patch/master/atomic.patch
patch atomic.h < atomic.patch
cd ../../build_unix
../dist/configure
make
sudo make install

Freetype and libPNG

On Mac OS X 10.8 and later, X11 and Freetype are no longer included by default. Even if you are using an earlier Mac OS X, I recommend installing your own Freetype. Homebrew offers the most recent version of freetype, but we'll need to explicitly include it in our configuration step later on.

brew install freetype

The PNG (Portal Network Graphics) format provides lossless-compressed image support. Although homebrew installs libpng as a dependency for freetype, it can be installed independently using the following command

brew install libpng

FTGL

FTGL is a free, open source library to enable developers to use arbitrary fonts in their OpenGL applications. We can install it as follows:

brew install ftgl

HDF5

HDF5 is a data model, library, and file format for storing and managing data. It supports an unlimited variety of datatypes, and is designed for flexible and efficient I/O and for high volume and complex data.

brew tap homebrew/science
brew install hdf5

SIP

Python's SIP (not to be confused with Mac OS X's SIP) is a tool that makes it very easy to create Python bindings for C and C++ libraries. It was originally developed to create PyQt, the Python bindings for the Qt toolkit, but can be used to create bindings for any C or C++ library.

brew install sip

PyQt4

PyQt4 provides Python bindings for Qt4. This software underlies every EMAN2 GUI application.

brew install pyqt

Required Python Modules

PIP

Pip is a package manager for python. To install it, use the system's own "easy_install" program

easy_install pip

Numpy

Numpy is an array manipulation package for python. To install, run

pip install numpy --upgrade

bsddb3

bsddb3 provides Python bindings for the Berkeley DB API.

Having previously defined the BERKELEYDB_DIR environment variable, we can install bsddb3 with pip very easily:

pip install bsddb3

PyOpenGL

PyOpenGL provides Python bindings for OpenGL. There is a pip package for it, available here, along with an acceleration package for optimization of certain graphics routines.

pip install PyOpenGL PyOpenGL-accelerate

IPython

IPython provides a rich toolkit to help you make the most out of using Python interactively. EMAN2 uses iPython for the "e2.py" interactive interpreter environment.

pip install ipython

Matplotlib

Matplotlib is a python 2D and 3D plotting library which produces publication quality figures in a variety of hardcopy formats and interactive environments. It can be installed with the following line:

pip install matplotlib

For examples and inspiration, see: http://matplotlib.org/gallery.html

Readline

pip install gnureadline

Optional (Recommended) Packages

Readline

Readline facilitates command history parsing in python.

brew install readline

JPEG

Jpeg is a library for writing JPEG image files.

brew install jpeg

TIFF

Libtiff is a library for reading and writing TIFF image files.

brew install libtiff

For EMAN2 Developers

If you spend a lot of time developing EMAN2, you will likely want these packages

brew install git cvs doxygen gnu-indent cscope

Excellent documentation for GIT is available at: https://www.atlassian.com/git/

Cleaning up

Cleaning things up and ensuring that everything has been installed properly, run:

brew linkapps
brew cleanup
brew doctor

Most warnings observed when running 'brew doctor' are harmless, especially if you don't use homebrew extensively. Unless problems arise later on, we recommend ignoring them.

The QUICK version

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew update && brew doctor
brew install qt --with-developer --with-docs --HEAD
brew install cmake boost boost-python ftgl freetype readline sip pyqt
brew tap homebrew/science && brew install hdf5 jpeg libtiff fftw gsl
brew install git cvs doxygen gnu-indent cscope
brew linkapps && brew cleanup && brew doctor
sudo easy_install pip
sudo -H pip install “ipython[all]” matplotlib spicy numpy gnureadline —upgrade
sudo -H pip install PyOpenGL PyOpenGL-accelerate --upgrade

Download Berkeley DB 5.3.28.tar.gz (instructions above)

tar -xf db-5.3.28
cd db-5.3.28
cd src/dbinc
curl -O https://raw.githubusercontent.com/narkoleptik/os-x-berkeleydb-patch/master/atomic.patch
patch atomic.h < atomic.patch
cd ../../build_unix
../dist/configure
make
sudo make install
sudo -H pip install bsddb3 --upgrade

Get EMAN2 source code

EMAN2 is now hosted on GitHub. Here is a direct link to dowload the source. Just hit the "clone or download" button:

https://github.com/cryoem/eman2

Configure EMAN2

1. Go to 'build' and type

ccmake ../eman2

2. Link all libraries properly.

When using Homebrew, this phase takes a little more care to get right. I suggest comparing your screen to the one I've pasted below (using OS X 10.8):

Build EMAN2

Once you're happy with the links, press 'c' to configure and then 'g' to generate the makefile.

8. Still inside build type:

make -j16 && make install

9. Add the EMAN2 folder (and the examples folder therein) to your PATH via the .bashrc file

export EMAN2DIR=${HOME}/username/EMAN2                                                      
export PATH=$EMAN2DIR/bin:$PATH                                                             
export PATH=$EMAN2DIR/examples:$PATH                                                        
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$EMAN2DIR/lib                                       
export PYTHONPATH=$PYTHONPATH:$EMAN2DIR/lib:$EMAN2DIR/bin                                              

Once you refresh your shell by calling the shell in the terminal or by restarting your computer, everything should work properly. If the building process goes through without errors, the basic tests to see whether EMAN2 is actually installed properly, are

10. A. Run e2speedtest.py from the command line

10. B. Run e2.py from the command line

10. C. Run e2display.py from the command line (assuming you're not on a cluster)

If everything went well, the above should run without failure and you can begin using EMAN2. If not, please double check that you've followed all instructions. If you have, feel free to post to the EMAN2 google group for assistance.
