Some comments on "Getting OOPIC working on Mac OS X":

1). Xoopic works fine with gcc 3.3 on Linux these days. There should
not be too much trouble when using gcc 3.3 on OS X.

2). XGrafix used not to work with Tcl/Tk 8.4 due to a problem in the
Tcl scripts that come with it. This has since been fixed, so you can
safely use Tcl 8.4 if it is already on your system. No need to go
through the trouble of instaling Tcl/Tk 8.3. (Note that Tcl/Tk 8.3
and earlier also still work.)

3). The problem with the "single capital letter variables" may have
more to do with the dummy arguments used in many constructors and
accessors than with the variable name itself. (Thanks to Brad Shadwick,
who dug this out.) For example, many accessors look like this:
void setA(Scalar _A) {A = _A;}
The symbol "_A" is reserved for the implementation, as all symbols
starting with an underscore are. On Mac OS X, <ctype.h> uses the
symbols "_A" and "_B", which clashes with the "illegal" use of these
symbols in Xoopic. Fortunately, a lot of such cases seem to have been
dealt with by now.

4). Building XGrafix used to generate lots of warnings. A recent
code clean-up took care of most of them. The remaining ones are
probably pretty harmless. (Only xgprintgif.h might need some changes
some day.)

A brief howto on getting oopic working on
Mac OS X (thanks go to Scott Kovaleski):

1).  Install X11R6/XDarwin (can obtain most up to date version from 
Fink)

2).  Use "sudo gcc_select 3.1", to switch to the gcc3.1 compilers.  I 
don' t know if gcc3.3 will work or not.

3).  Download and install Tcl/Tk 8.3.5 (the Unix version, NOT the Mac 
version).  I had to do this from source...  Fink distributes 8.4.5, 
which didn't work.  I recommend doing this from a directory hung off of 
"/" (like "/Download", for instance) especially if you have multiple 
partitions (as I do).  The use of spaces in path names (which Mac 
allows) can cause some infuriating problems in the configure and make 
steps.

4).  Fink has some of the other optional packages, like FFTW and HDF5, 
if you want that capability.

5).  Get and unpack xgrafix and xoopic.

6).  Configure, make, and install xgrafix.  You will probably need to 
use all of the "--with-XXX" flags for the newly installed Tcl and Tk.  
You should get warnings but no errors.

7).  Configure xoopic.  Use the "--with-XXX" flags again for Tcl and Tk.

8).  In order to "make", some minor surgery must be done to a few of 
the source files.  Basically, the compiler doesn't like variables with 
a single, capital letter (e.g. Scalar Q).  It will return an error if 
these are found.  I edited the source and header files, and changed 
those single capital letter variables to something else (e.g. "Scalar 
Q" and other occurrences of Q become "Scalar Q1".  The errors are thus 
eliminated.  I have included what I think is a complete list of the 
files I changed.  Look for variables in them like "A", "B", "Q", "R", 
"L", "C", "I".  If an error comes up, look in the offending source file 
for a single capital letter and add a one to it (or something else).  
(You can just run make, as I did, and the compiler will tell you which 
files are a problem and the line number of the problem).

9).  After making those changes, make and make install should run 
without incident... and you are ready to go.
