steps installing starlink gaia

1. download latest starlink distribution (hikianalia, of writing):

   http://starlink.jach.hawaii.edu/starlink/hikianaliadownload

2. uncompress .tar.gz. new star directory created. can move other place (for instance, /users/shared/star, or /star)

   1. as installer 0.7gb, might want delete after installation has been successful.

3. depending on default shell:

   1. for c (csh, tcsh) shells:

      1. create starlink_dir environment variable pointing star directory left (i.e., /users/shared/star):

         setenv starlink_dir /users/shared/star 

      2. source chsrc files

         source $starlink_dir/etc/login source $starlink_dir/etc/cshrc 

      3. you can combine steps above creating alias called start_starlink add .cshrc file, start starlink libraries when needed:

         alias start_starlink 'setenv starlink_dir /users/shared/star; source $starlink_dir/etc/login; source $starlink_dir/etc/cshrc' 

   2. for bourne (sh, bash, zsh) shells:

      1. create starlink_dir environment variable pointing star directory left (i.e., /users/shared/star):

         export starlink_dir=/users/shared/star 

      2. source chsrc files

         . $starlink_dir/etc/profile 

      3. you can combine steps above creating alias called start_starlink add .cshrc file, start starlink libraries when needed:

         alias start_starlink='export starlink_dir=/users/shared/star; . $starlink_dir/etc/profile' 

so, after typing start_starlink, can type gaia launch starlink gaia.

fixing missing gfortran

in x86_64 systems, if launching gaia fails message:

dyld: library not loaded: /usr/local/lib/libgfortran.3.dylib referenced from: /users/jdsant/downloads/star/bin/gaia/gaia_wish reason: image not found 

you need make sure have gfortran libraries installed, , gaia expects them.

you can try use locate libgfortran.3.dylib, , copy /usr/local/lib , or make symlink it. see, instance, http://starlink.jach.hawaii.edu/starlink/hikianaliadownload#snowleopard64-bitdistribution
