It should compile on any machine that uses gcc and supports IEEE floating point arithmetic, and has been tested under GNU/Linux. It uses an included library, gnulliver.c, that automatically handles integer and floating point Big-endian/Little-endian byte swapping to match Big-endian/network order on any computer. gnulliver.c can be used separately under the LGPL 2.1. This is a redesign of JPL's original FORTRAN code, available on JPL's FTP website (ftp://ssd.jpl.nasa.gov/pub/eph/export/), with some added flexibility (including patching some inconsistencies in the original JPL data files). 'Ephemeris' is not associated with JPL or NASA, but just uses JPL's data.<br /> |User level=none<br /> |Status=Live<br /> |Component programs=eph2eph,eph2asc,asc2eph,ephcmp,headcmp,testeff,ephcoeff,vtransit,gnulliver.c<br /> |Homepage URL=http://www.ephemeris.com/software.html<br /> |VCS checkout command=<br /> |Computer languages=C<br /> |Documentation note=User README included and available from http://www.ephemeris.com/README.txt<br /> |Paid support=<br /> |IRC help=<br /> |IRC general=<br /> |IRC development=<br /> |Related projects=Planet_Finder<br /> |Keywords=position,astronomy,planet,solar system,ephemeris,NASA,JPL<br /> |Is GNU=n<br /> |Last review by=Janet Casey<br /> |Last review date=2008-01-07<br /> |Submitted by=Database conversion<br /> |Submitted date=2011-04-01<br /> |Version identifier=1.0<br /> |Version date=2004-05-22<br /> |Version status=beta<br /> |Version download=http://www.ephemeris.com/ephcom-1.0.tar.gz<br /> |License verified date=2004-05-24<br /> |Version comment=1.0 beta released 2004-05-22<br /> }}<br /> {{Person<br /> |Role=Maintainer<br /> |Real name=Paul Hardy<br /> |Email=unifoundry@unifoundry.com<br /> |Resource URL=<br /> }}<br /> {{Resource<br /> |Resource audience=Bug Tracking<br /> |Resource kind=VCS Repository Webview<br /> |Resource URL=http://www.ephemeris.com/software.html<br /> }}<br /> {{Resource<br /> |Resource audience=Bug Tracking,Developer,Support<br /> |Resource kind=E-mail<br /> |Resource URL=mailto:bugs@ephemeris.com<br /> }}<br /> {{Resource<br /> |Resource audience=Help<br /> |Resource kind=E-mail<br /> |Resource URL=mailto:mystars@ephemeris.com<br /> }}<br /> {{Software category<br /> |Interface=library<br /> |Science=astronomy<br /> |Use=science<br /> }}<br /> {{Project license<br /> |License=LGPLv2.1<br /> |License verified by=Janet Casey<br /> |License verified date=2004-05-24<br /> }}<br /> {{Software prerequisite<br /> |Prerequisite kind=Required to build<br /> |Prerequisite description=make<br /> }}</div>
