[MACTCL] Converting simple Tcl extension from IRIX to Mac OS X

[Smith, M. T <MSmith@SIKORSKY.COM>]

Hello,

I am new at OS X development, coming from a strictly UNIX
background.

I have a simple program written in Tcl/Tk with a C++ backend
which I use on my IRIX machine.

Taking the program to Mac OS X has been mostly simple,
but, I can't seem to get AquaTcl8.4.2 to load the .so file.

when i try:

<wish prompt> load ./logbook.so logbook

I get a message about logbook.so is not a Mach-o library.

The makefile is below.  The weird thing is a friend's G4 with wish8.3
it worked fine.

I am using 10.2.4, G4 1.25 dual Firewire800
with the 10.2.3 developer tools disk.

Thanks
Todd Smith
