Debian, Ubuntu, Linspire, Mint etc. users, please download and try out my .deb packages for OpenCASCADE at http://lyre.mit.edu/~powell/opencascade/ .
The package should be complete and usable, but is not ready for upload yet. The primary TO-DO item is to add the samples, then split it up properly; see the debian-science mailing list archives for details. Please test it hard, we want to know what works and what doesn't, what could be improved, etc.
The .dsc and .changes files are signed with my key in the Debian keyring. If you have the inclination, please build the orig.tar.gz using the build instructions in the package, and unpack it and compare with the unpacked upstream sources. I want to make sure the description is thorough and accurate, so people can verify the packaging.
I am using it now to a build a new Salomé package, which is almost ready, but has runtime issues; see the Salomé forum for details.
Sylvestre Ledru has applied for an alioth site and SVN repository, so this package will be team-maintained in the future.
