I found two points when installing OpenCASCADE6.3.0 on Ubuntu Intrepid Ibex. The outdated ltmain.sh led to a heavily memory leaking libtool which crashed the system. This can be solved by using the system libtools ltmain.sh. The second is a small file creation problem in WOKUnix.
I would like to also build a debug library. Should I just copy the source over to a new directory (e.g. OpenCASCADE6.3.0-dbg) and perform the steps anew (with debug enabled)? Do I need to specifically define a new installation (make install) directory as well in order to keep both the production and debug versions?
you have to run configure/make/make install again with a new --prefix option.
