[Caml-list] Aqua ocamlbrowser on Mac OS X

[Caml-list] Aqua ocamlbrowser on Mac OS X

[Shivkumar Chandrasekaran]

Following Trevor's suggestions (see 
http://caml.inria.fr/archives/200211/msg00163.html) I am now able to 
get *my* labltk programs to run in native Mac OS X Aqua mode (using 
TclTkAquaBI-8.4.5.0.dmg from 
http://www.maths.mq.edu.au/~steffen/tcltk/TclTkAqua/). Thanks, Trevor!!

What follows is what I did to get ocamlbrowser to run as a native Aqua 
app. First I followed Trevor's suggestions. That did not work if I 
double-clicked on Ocamlbroswer.app. I then tried from the command line

open -a Ocamlbrowser

That at least let ocamlbrowser display its error message that the 
options to the command line were at fault. All the Console showed in 
the log was a dreaded "RegisterProcess failed (error -50)" message.

So I edited the source file ..../otherlibs/labltk/browser/main.ml and 
essentially commented out the command line argument parsing step. I did 
"make" and moved the new binary into OCamlbrowser.app/Contents/MacOS/ 
and everything works pretty nicely now. The only problem I have noticed 
is that clicking in the scroll bar does not work. You have to catch the 
scroll-button and move it with the mouse. Everything else seems to work 
too.

If somebody needs the modified source I can email it. I hope some 
similar hack can make labltk work too.

To make this complete we must find some way of passing the command line 
options, but that is for somebody else to do.

I should add that I can still only get it to run from the Terminal via

open -a Ocamlbrowser

I debugged the following when getting a version of Unison running in 
Aqua:

     /* When you click-start or use the open command, the program is 
invoked with
        a command-line arg of the form -psn_XXXXXXXXX.  The XXXXXXXX is 
a "process
        serial number" and it seems to be important for Carbon programs. 
  We need
        to get rid of it if it's there so the ocaml code won't exit.  
Note, the
        extra arg is not added if the binary is invoked directly from 
the command
        line without using the open command. */
     if (argc == 2 && strncmp(argv[1],"-psn_",5) == 0) {
         argc--;
         argv[1] = NULL;
     }

I just put that in main before calling caml.  (I am calling caml from 
ObjC.)
