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:
$ 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
See these instructions from James Chamberlain.
These instructions Worked For Me as of September 2012 on OSX 10.8.
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
$ brew install --HEAD astrometry.net
if you like to live dangerously (but trendily).
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"
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:
If you installed the libraries listed above, build the plotting code:
$ make extra
$ 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
$ 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"
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:
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)
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).
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.)
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"
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"
make NETPBM_INC="-I/to/netpbm" NETPBM_LIB="-L/to/netpbm/lib -lnetpbm"
Ditto, with WCSLIB_INC, WCSLIB_LIB, WCS_SLIB
