Build instruction for OC5.1 on Mac OS X

Instructions for porting opencascade to OS X (10.3). The intructions to follow are relative to our own testing and environment. The computer used is a dual G5 running OS X.3.

- install fink

- install required packages through fink including tcl, tk, tix, fltk

- uncompress the opencascade source for Intel Linux. We couldn't get the graphical installer to unpackage things on OS X. so we had to switch to Intel Linux to unpack the source code. This is for OpenCascade 5.1. Copy the tarball to OS X and unpack using the command: tar -xvf.

- Use the provided diff file to make modifications in a few source files. NB: I ran the diff between the working OC5 folder and the uncompressed sources. So please make sure that your modify yours considering your own environment and file paths. The left arrow is the modification the right is the original source. Make sure that your put the full path ending with OpenCASCADE5.1/ros as CASROOT in the env.csh file.

- run configure using the installed tcl/tk, the mac java and the X11 gl libraries, as follows:
./configure --with-tcl=/sw/lib --with-tk=/sw/lib --with-gl-include=/usr/X11R6/include --with-gl-library=/usr/X11R6/lib --with-java-include=/System/Library/Frameworks/JavaVM.framework/Headers --prefix=/where/you/want/to/install/
Using the "--prefix" is optional. if not used then the executable by default will be installed in /usr/local/

-upon successful configuration, if you are running csh and want to output to a file, run make as follows:
make |& tee filename

-upon successful make, run a make install
make install |& tee filename

-if everything is done successfully, now you are ready to run the env.csh file to set the environment variables: run "source env.csh" in the Opencascade directory and you are ready to run TTOPOLOGY...

NB: From here there are two major bugs we are trying to fix.
1) memory allocation problem when running extended draw
2) running OC5 from X11 on a remote computer. This only runs locally.
