how to install OpenCASCADE in Ubuntu

I use the following procedure...

First, get yourself the build tools from Ubuntu! Specifically, the following should get everything you need:

$ sudo apt-get libtool autoconf automake gfortran gdebi

(gfortran is GNU FORTRAN). If you got any of those tools from their home web sites, get rid of them before installing the Ubuntu versions, or much confusion may result! (The beauty of a distro is that they take care of making sure that this automake works with this autoconf works with...)

Now your procedure should look like

$ sudo -i

# Now move to the directory where the target file is
$ cd foo-x.y.z

$ tar xf foo-x.y.z.tar.gz
$ cd ros
$ ./build_configure
$ ./configure
$ make
$ cp /usr/local/draw.sh /usr/local/draw.sh.old
$ rm /usr/local/draw.sh

# At this point, it may be useful to delete the old version of
# Open Cascade if you haven't yet, and install the new.

# You can remove it from your system anytime using:

dpkg -r opencascade

$ checkinstall make install |& tee build.log

if this command has problems, you can check build.log
for errors

You may see the following...

"...is not a
*** Warning: debian policy compliant one.
Please specify an alternate one"

Press ENTER

During the MAKE function on the last line, you will probably be told the value you've entered can't be accepted. This is a version number. Enter any number from 0-9, you'll get a chance to change it later.

You MUST have a version number!

This package will be built according to these values:

0 - Maintainer: [ root@desktop ]
1 - Summary: [ OpenCascade660 ]
2 - Name: [ opencascade ]
3 - Version: [ 660 ]
4 - Release: [ 1 ]
5 - License: [ GPL ]
6 - Group: [ checkinstall ]
7 - Architecture: [ amd64 ]
8 - Source location: [ ros ]
9 - Alternate source location: [ ]
10 - Requires: [ ]
11 - Provides: [ ros ]
12 - Conflicts: [ ]
13 - Replaces: [ ]

When shown your version of the table above, pay attention to lines 1, 2, and 3. If those lines are in the form shown you should do alright. If you don't know what any of the entries are, leave them alone.

When you have the table above the way you want it, and have pressed ENTER, the "checkinstall make install" command tar will finish.

When the "checkinstall make install" line is done, you'll have a file named like, "OpenCASCADE654.tar.gz" in the ros directory. Right-Click this file from your desktop, and use GDEBI to install it.

What's happening here is that the build_config script is preparing the kit to the point where you could roll it back up into a new tar ball for distribution, with directions to the user to do the ./configure && make && make install with the kit. The whole autoconf/automake facility makes it possible to provide packages that will (ultimately) build and compile on systems as diverse as Windows, Linux and other Unix variants, and some proprietary operating systems.

Hi, i tried to install opencascade, but i have no idea what do i have to do, tried to understand but failed. 
is there an easy way to run the software? 

thanks

IT WOULD BE FORMABLE THAT OPENCASCADE 7.3 WAS AVAILABLE ON deb-multimedia.org, IT WOULD BE A GREAT RELIEF FOR THE DESIGN STUDENT USER, I ALSO BELIEVE THAT OPENCASCADE IS AN APPLICATION TO THE HEIGHT OF solidworks OR siemens-nx OR EVEN BETTER, STILL I HAVE NOT HAD LIKE TO TRY IT.
