Hi All,

I've been working on a general c/c++ astrodynamics library. It is strictly a work in progress, and so far only includes the basic astronomy routines. Next up will be the orbit propagators, and tracking stuff. Anyway, its time for it to see the outside world. It can be downloaded from here:

http://homepage.mac.com/pclwillmott/GAL/index.html

Its released under GPL 2 and was developed under OSX using the GNU development tools, so should compile OK on UNIX / GNU Linux / and under cygwin in Windows.

The routines are primitives, and it is deliberatly not framework based, so you can rip bits for your projects without lots of baggage.

Please let me know any comments.

Hi Paul, I had a go at your GAL package on my Debian 4.0 hppa box. Download, unpack, configure, make and make install work well but make check barfs with the trace you'll see quoted below. I don't have the programming skills to do anything with it but I'm always glad to try and break software :-) .
