[geomview-users] Current status of Cygwin for Geomview.

[<L....@su...>]

Have just built Geomview 1.9.4 under latest Cygwin 1.7 (and updated my instructions at:
http://sat-net.com/L.Wood/software/SaVi/building-under-Windows/ 
as I go along - Cygwin's change in X server means removing all X11R6 references, etc.)

Geomview builds fine even with opengl (though the xforms modules didn't build even though I installed latest xforms where it should be in geomview-1.9.4/xforms and also did make install - odd, need to look into that), but using opengl results in very flickery output and then kills the Xserver with SaVi about ten seconds after loading a constellation and animating. Unsurprising, but slightly better than it was a year ago, when it didn't even get that far.

geomview -noopengl is usable, but slow.

(yes, I know these instructions really should live on www.geomview.org. But Sourceforge has made updating the content hosted websites via logging into the server really painful, unless there's a way of slaving content and mirroring from some master elsewhere that could be set up that I'm missing. And I'm the only person attempting to use Geomview under Cygwin that I know of...)

Noticed this:

(echo 'char builddate[] = "'"`date +%Y%m%d%H%M`"'";'; \
         echo 'char buildinfo1[] = "'"  By `whoami`@`hostname`[`uname -s`-`uname -r`]"'";'; \
         echo 'char buildinfo2[] = "'"  On `date`"'";'; \
        ) > buildinfo.c

../../../../libtool: line 1935: cd: yes/lib: No such file or directory
libtool: link: cannot determine absolute directory name of `yes/lib'

Didn't stop the (hours-long; Cygwin filesystem performance still v. sucky under Win7) build. Any clues?

Other stuff like:

gcc -DHAVE_CONFIG_H -I. -I../../../.. -I../../../../include    -g -O2 -MT polymerge.o -MD -MP -MF .deps/polymerge.Tpo -c -o polymerge.o polymerge.c

seems harmless.

So, Cygwin's still in the 'use with Geomview only if you really have to' camp; Ubuntu under Virtualbox is still way better.

cheers,
