Xfractint is the Unix port of fractint, which runs under X.
Fractint is an IBM PC program to generate fractals, and was written by
the the Stone Soup Group. The Unix port was done by Ken Shirriff.
To compile, do:
make xfractint
If you are compiling under SunOS, Ultrix, AIX, or HPUX, read the Makefile and
uncomment the approprite lines.
To find out what features are new in this version, look at the "versions" file.
NOTES ON POTENTIAL PROBLEMS:
Important: if you report a bug, _please_ specify what version of xfractint
you are using.
Xfractint won't compile unless your compiler handles function prototypes.
You have the best chance of compiling xfractint if you use gcc. SunOS cc
does not work.
To check if your compiler handles prototypes, try compiling the following
two line program:
int foo(int bar);
main() {}
If you get line 1: syntax error at or near type word "int"
then your compiler doesn't handle prototypes, so you won't be able to
compile xfractint. (One person managed to use "unproto" from
comp.sources.misc volume 26 to strip out the prototypes, so the standard
Sun compiler would work. You can try this, but I'm not supporting it.)
If you get "gcc: unrecognized option `-target'" when you compile, the
problem is probably that you are using an old version of gcc (1.36). You
need a newer version.
If xfractint hangs in the title screen, the problem is probably that your
display cannot update fast enough for the scrolling. The solution is to
use the -slowdisplay flag.
If you are using Openwindows and can't get xfractint to accept input, add
to your .Xdefaults file:
OpenWindows.FocusLenience: True
To use all 256 colors, use the -private flag, discussed in the man page.
If you cannot view the GIFs that xfractint creates, the problem is that
xfractint creates GIF89a format and your viewer probably only handles
GIF87a format. Run "xfractint gif87a=y" to produce GIF87a format.
The program is a straight port from the IBM PC, and it thus uses the IBM style
user interface. See the man page for more details, and a description of
what to use for ctrl-pageup, etc.
Running "make makedoc" will create a file fractint.doc, which contains the
online documentation in ascii form.
