Hi Jane, 
I was trying to build occ 6.5.1 on mcs network, but I had to modify the file 
src/OSD/OSD_MAllocHook.cxx 
according to this patch: 

diff -urp ros/src/OSD/OSD_MAllocHook.cxx ../OCC651/ros/src/OSD/OSD_MAllocHook.cxx 
--- ros/src/OSD/OSD_MAllocHook.cxx 2011-05-19 06:24:52.000000000 -0500 
+++ ../OCC651/ros/src/OSD/OSD_MAllocHook.cxx 2011-12-12 11:52:45.193338446 -060 
0 
@@ -14,6 +14,7 @@ 

#include <set> 
#include <map> 
+#include <stdlib.h> 

#ifndef SIZE_MAX 
#define SIZE_MAX UINT_MAX 

... 

Otherwise, it errors out about missing atol() definition in this file. 

What compilers are you using ? 
I configured with this command: 

./configure --enable-shared --enable-static --with-gl=/usr --with-xmu=/usr --with- 
tcl=/usr/lib --with-tk=/usr/lib --disable-debug --enable-production --prefix=/home 
s/fathom/3rdparty/occ/OpenCASCADE6.5.1/gcc CXXFLAGS=-I/homes/fathom/3rdparty/FTGL/ 
lib/include/FTGL --with-ftgl=/homes/fathom/3rdparty/FTGL/lib --with-freetype=/home 
s/fathom/3rdparty/freetype-2.3.7/lib 


Thanks, 
Iulian

New Revision: 5257 

Modified: 
cgm/trunk/geom/OCC/occ_patches_6.5.1 
Log: 
Temporally fixed the mcnp2cad/INP-complement case, it's been there for quitely a long time that whenever it detected a curve curve intersection at middle point, it came out with a crash for finding next intersection of the intersect function in OCC, the code there said it's impossible, but it quite often happen. I know this might not be a best fix, but by not crash out and allow the flow going on, it returns the next intersection if it indicates so, will file a bug report, don't know if they will accept since it's an internal process, no UI command corresponding to this function.
