Yes, they are shared objects, but they also should be recognized by configure.

If you use configure with " --enable-occ --with-occ-prefix=/home2/oswald/extlib/OpenCASCADE/OpenCascade_6_2_0/ros/Linux/ ", does it recognize OCC ?


If it works, what you can do is to put in your /home2/oswald/extlib/OpenCASCADE/OpenCascade_6_2_0/ directory a symbolic link from  lib  to  ros/Linux/lib  and one from inc  to ros/inc , then configure again with " --enable-occ --with-occ-prefix=/home2/oswald/extlib/OpenCASCADE/OpenCascade_6_2_0/ " , and if it works, make ...

Cheers,

Dave
