Building Opencascade from source for I386 for Ubuntu Linux. Continued even a little more

Recapping.. I downloaded the tar source, unzipped it compiled it.
Now then the deb package gets deployed it supposed to stick everything into the “Linux Filesystem Hierarchy Standard (FHS) locations: libraries in /usr/lib, headers in /usr/include, executables in /usr/bin.”
Apparently since the open cascade had so many header files they were place in /usr/include/opencascade instead of /usr/include/ I think this will have some implications that I don’t fully understand at the moment

(in the directory where the .debs are).
sudo dpkg -i *.deb

jonas@unbuntu2:~$ cd OCC_orig_tar
jonas@unbuntu2:~/OCC_orig_tar$ ls

Ok, now I’m a little curious about what is getting put where.
You can find this out by doing this:

Description: OpenCASCADE CAE platform shared library
OpenCASCADE is a suite for 3D surface and solid modeling, visualization, data
exchange and rapid application development. It is an excellent platform for
development of numerical simulation software including CAD/CAM/CAE, AEC and
GIS, as well as PDM applications.
This package contains the shared library.

There’s a lot more I just got it out there.

Now just a quick test to see if one of these files is really there.
jonas@unbuntu2:~/OCC_orig_tar$ sudo updatedb
[sudo] password for jonas:
jonas@unbuntu2:~/OCC_orig_tar$ locate
Yep all there…. I think I must have been from Missouri in a past life… There are so many files in the OCC_orig_tar sub-folders I’m loosing the trees in the forest.
I still need to get the non-platform dependant .deb files from. Going back to the original instructions:

For me the problem was I don’t have a amd64 processor… So that’s why I needed to build from source.
I think I’m going to put the _all.deb files into a different sub-directory and backup on my thumb drive..
(I’m planning on whipping my drive again and re-install with the next version of ubuntu… and summarize with a nice set of install directions on my web page… oops digressing here
jonas@unbuntu2:~$ mkdir OCC_all_deb

opencascade-doc_6.2.0-7_all.deb opencascade-examples_6.2.0-7_all.deb

I guess all is have to do know is to install the packages and check for missing dependencies:

jonas@unbuntu2:~/OCC_all_deb$ dpkg -i *.deb
dpkg: requested operation requires superuser privilege
jonas@unbuntu2:~/OCC_all_deb$ sudo dpkg -i *.deb

Wow… now that just seemed way to easy….
Now I want to get an idea where all this stuff got put..
dpkg-deb –contents opencascade-doc_6.2.0-7_all.deb
Tells me basically everything gets dumped under:
Manually checking: Yep all there 🙂

Now checking the other file:
dpkg-deb –contents opencascade-examples_6.2.0-7_all.deb
Tells me that everything gets dumped into:
Looks like it did that..

Ok…. Now here’s the magic moment….
Will DRAWEXE fire up from a fresh terminal session and can I pload ALL (which loads in all the plugins..)
Answer is:
jonas@unbuntu2:~$ DRAWEXE
the CASROOT variable is mandatory to Run OpenCascade
No default file
% % pload ALL
Plugin file name has not been specified. Defaults to DrawPlugin
Failed to load plugin: Neither CSF_DrawPluginDefaults, nor CASROOT variables have been set

Not quite yet…. I think I know what to do, more in the next instalment.
