.. _build: Building/installing the Astrometry.net code =========================================== Grab the code:: wget http://astrometry.net/downloads/astrometry.net-latest.tar.bz2 tar xjf astrometry.net-latest.tar.bz2 cd astrometry.net-* Build it. The short version:: make make py make extra make install # to put it in /usr/local/astrometry # or: make install INSTALL_DIR=/some/other/place The long version: Prerequisites ------------- For full functionality, you will need: * GNU build tools (gcc/clang, make, etc.) * cairo * netpbm * libpng * libjpeg * libz * bzip2 * python (probably >= 2.4; 2.7 or 3.6 preferred) * numpy * swig (>= 2.0) * fitsio https://github.com/esheldon/fitsio or astropy http://www.astropy.org/ or pyfits: http://www.stsci.edu/resources/software_hardware/pyfits (version >= 3.1) * cfitsio: http://heasarc.gsfc.nasa.gov/fitsio/ Ubuntu or Debian-like systems: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: $ sudo apt-get install libcairo2-dev libnetpbm10-dev netpbm \ libpng12-dev libjpeg-dev python-numpy \ python-pyfits python-dev zlib1g-dev \ libbz2-dev swig cfitsio-dev For example, in Debian 9 (Stretch):: $ sudo apt-get install libcairo2-dev libnetpbm10-dev netpbm \ libpng-dev libjpeg-dev python-numpy \ python-pyfits python-dev zlib1g-dev \ libbz2-dev swig libcfitsio-dev CentOS 6.5 / Fedora / RedHat / RHEL -- Detailed Instructions: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ See these `instructions from James Chamberlain `_. Arch Linux ^^^^^^^^^^ A package can be installed from the `Arch Linux (AUR) `_. Mac OS X using homebrew: ^^^^^^^^^^^^^^^^^^^^^^^^ These instructions *Worked For Me* as of September 2012 on OSX 10.8. First set up homebrew: * grab `XCode `_ (from the Apps Store. Free, but you still need a credit card. Argh.) * grab `XCode Command-line utilities `_ * grab `XQuartz `_ * grab `Homebrew `_ * grab `pip `_ if you don't have it already Get homebrew dependencies that need special instructions:: $ brew install --HEAD --use-gcc netpbm Optionally, grab some other handy homebrew packages:: $ brew install cfitsio --with-examples $ brew install md5sha1sum # OSX doesn't come with this?! For shame Get our fork of homebrew-science and install:: $ brew tap homebrew/homebrew-science $ brew install astrometry-net Or:: $ brew install --HEAD astrometry.net if you like to live dangerously (but trendily). Mac OS X using Fink: ^^^^^^^^^^^^^^^^^^^^ Use apt-get install as per the Debian instructions above (leaving out ``zlib1g-dev`` because it's already included with OSX). Note that to use Fink you will need to add something like this in your ``~/.profile`` or ``~/.bashrc`` file:: . /sw/bin/init.sh export CFLAGS="-I/usr/local/include -I/sw/include" export LDFLAGS="-L/usr/local/lib -L/sw/lib" Getting/Building ---------------- If you don't have and can't get these libraries, you should still be able to compile and use the core parts of the solver, but you will miss out on some eye-candy. Build the solving system:: $ make If you installed the libraries listed above, build the plotting code:: $ make extra Install it:: $ make install You might see some error message during compilation; see the section ERROR MESSAGES below for fixes to common problems. By default it will be installed in ``/usr/local/astrometry`` . You can override this by either: * editing the top-level Makefile (look for INSTALL_DIR); or * defining INSTALL_DIR on the command-line: For bash shell:: $ export INSTALL_DIR=/path/to/astrometry $ make install or:: $ INSTALL_DIR=/path/to/astrometry make install For tcsh shell:: $ setenv INSTALL_DIR /path/to/astrometry $ make install The astrometry solver is composed of several executables. You may want to add the INSTALL_DIR/bin directory to your path: For bash shell:: $ export PATH="$PATH:/usr/local/astrometry/bin" For tcsh shell:: $ setenv PATH "$PATH:/usr/local/astrometry/bin" Auto-config ----------- We use a do-it-yourself auto-config system that tries to detect what is available on your machine. It is called ``os-features``, and it works by trying to compile, link, and run a number of executables to detect: * whether the "netpbm" library is available * whether certain GNU-specific function calls exist You can change the flags used to compile and link "netpbm" by either: * editing util/makefile.netpbm * setting NETPBM_INC or NETPBM_LIB, like this:: $ make NETPBM_INC="-I/tmp" NETPBM_LIB="-L/tmp -lnetpbm" You can see whether netpbm was successfully detected by:: $ cat util/makefile.os-features # This file is generated by util/Makefile. HAVE_NETPBM := yes You can force a re-detection either by deleting util/makefile.os-features and util/os-features-config.h, or running:: $ make reconfig (which just deletes those files) Overriding Things ----------------- For most of the libraries we use, there is a file called ``util/makefile.*`` where we try to auto-configure where the headers and libraries can be found. We use ``pkg-config`` when possible, but you can override things. ``*_INC`` are the compile flags (eg, for the include files). ``*_LIB`` is for libraries. ``*_SLIB``, when used, is for static libraries (.a files). gsl: ^^^^ You can either use your system's GSL (GNU scientific library) libraries, or the subset we ship. (You don't need to do anything special to use the shipped version.) System:: make SYSTEM_GSL=yes Or specify static lib:: make SYSTEM_GSL=yes GSL_INC="-I/to/gsl/include" GSL_SLIB="/to/gsl/lib/libgsl.a" Or specify dynamic lib:: make SYSTEM_GSL=yes GSL_INC="-I/to/gsl/include" GSL_LIB="-L/to/gsl/lib -lgsl" cfitsio: ^^^^^^^^ For dynamic libs:: make CFITS_INC="-I/to/cfitsio/include" CFITS_LIB="-L/to/cfitsio/lib -lcfitsio" Or for static lib:: make CFITS_INC="-I/to/cfitsio" CFITS_SLIB="/to/cfitsio/lib/libcfitsio.a" netpbm: ^^^^^^^ :: make NETPBM_INC="-I/to/netpbm" NETPBM_LIB="-L/to/netpbm/lib -lnetpbm" wcslib: ^^^^^^^ Ditto, with ``WCSLIB_INC``, ``WCSLIB_LIB``, ``WCS_SLIB`` cairo: ^^^^^^ ``CAIRO_INC``, ``CAIRO_LIB`` jpeg: ^^^^^ ``JPEG_INC``, ``JPEG_LIB`` png: ^^^^ ``PNG_INC``, ``PNG_LIB`` zlib: ^^^^^ ``ZLIB_INC``, ``ZLIB_LIB``
