/b Hints by strick:

PolyWorld by Larry Yaeger is available on SourceForge
at http://sourceforge.net/projects/polyworld/ .
The authors usually run it on Mac OSX.
It took a little work to run it on Linux.


 I compiled on Fedora Core 4
/tt [gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)].

First, build and install Qt4.0.1.   Since FC4 already
has version 3.3.4 of Qt, install it in /usr/new:

/pre(
./configure --prefix=/usr/new
make
su
make install
exit
/pre)


Then you can download and build Polyworld.
The file
/link http://sourceforge.net/project/showfiles.php?group_id=127235&package_id=139284&release_id=364985 polyworld_1.0.zip
does NOT have a toplevel directory named
"polyworld" so you want to make one first.
You also need to apply this patch file:
/file polyworld-1.0-patch-linux1.txt


/pre(
mkdir polyworld
cd polyworld
unzip ~/Desktop/polyworld_1.0.zip
patch -p1 < ~/Desktop/polyworld-1.0-patch-linux1.txt
/pre)



The README says to use ./buildit but
that just runs "qmake" and then "make".
I prefer to run "qmake" then "make" myself.
(If you make changes to Makefile, you don't want to run "qmake" again, or you clobber them;
just rerun "make".)

/b You must add ```/usr/new/bin''' to the front of your PATH before runing the "qmake" step,
so that the /usr/new version of Qt will be used.

/pre(
export PATH=/usr/new/bin:$PATH
qmake
make
./Polyworld -geometry 250x250
/pre)

When I run ./Polyworld without specifying a geometry, I get an empty black main window.
Specifying a smaller geometry (like
/tt ./Polyworld -geometry 250x250
), I get a working display.

More Hints:
/list(
* Edit the file ```worldfile''' to change parameters.
* Here is Larry Yaeger's page for PolyWorld: http://www.beanblossom.in.us/larryy/PolyWorld.html
* This PDF gives detail about its features: http://www.beanblossom.in.us/larryy/Yaeger.ALife3.pdf

/subsection Bugs:

Unfortunately, I just found out Menus are missing.
I didn't know they were there!
What I see is like this:
