[SAC-HELP] HowTo compile SAC under Cygwin

[Andreas Wuestefeld]

Hi everybody


As of SAC version 101.1 the SAC development team made some adoptions to
ease installation under CYGWIN (http://www.cygwin.com/)

If you want to compile SAC under CYGWIN, you mainly need to have
installed several packages. Use the CYGWIN setup utility!

I list the necessary packages here by category (as of CYGWIN1.5):
=====================================================
1) Packages which *need* to be installed
Devel:
    * gcc-g++
    * libncurses-devel
    * make
    * readline
Libs:
    * sunrpc
X11:
    * xorg-x11-devel

=====================================================
2) some nice-to-haves (but *not* required!!!)
Editors:
    * nedit
    * nano
Shells:
    * rxvt (terminal with copy-paste function)
System:
    * util-linux (collection of linux utils, e.g. "more")
=====================================================


After you installed these, you should be able to compile SAC as
described in the readme.buildsac file

$> cd /path/to/unzipped/sac/
$> ./configure
$> make
$> make install

SAC is now installed under /usr/local/sac
The only thing left, is to set your environment variable in the .bashrc
according to the readme-file (Attention: SACAUX=${SACHOME}/winaux under 
CYGWIN)

     export SACHOME=/usr/local/sac
     export PATH=${PATH}:${SACHOME}/bin
     export SACAUX=${SACHOME}/winaux
     export SAC_USE_DATABASE=0
     export SAC_PPK_LARGE_CROSSHAIRS=1


Now, to run SAC, you need an XWindow server running in the background.
This is already installed, you just have to start it. I have set an
alias in my .bashrc
alias X='XWin -multiwindow -clipboard -silent-dup-error -logverbose 0 &'
(type   XWin --help   for more information)

Be sure, you also have the DISPLAY environment varible set in your .bashrc:
     export DISPLAY=127.0.0.1:0.0

Now, the first time you start sac in a session type
$> X
$> sac
Try it:
SAC> fg
SAC> plot

At least, that worked for me :-)


Good luck
