Re: [deal.II] OpenCASCADE Technology (OCCT) 7.2.0 coming to Debian - implications for deal.II

Kurt, 

in principle deal.II does not require OCE. It can work also with OCCT (it will 
use whatever it finds available, unless someone changed this behaviour).

When OCCT will be packaged into debian, I’m sure we can make dealii use that 
instead of OCE.

Best,
Luca.

[deal.II] OpenCASCADE Technology (OCCT) 7.2.0 coming to Debian - implications for deal.II

2018-03-10 Thread Kurt Kremitzki
Hello,

I work with the FreeCAD project and have been working on getting OCCT 7.2.0 
back into Debian (for those not aware, it was removed from license reasons 
and replaced with OCE.) However development on OCE has slowed while the 
pace has picked up for OCCT, resulting in several improvements we'll need 
for our upcoming 0.17 release.

Since deal.II depends on OCE, I wanted to reach out to all of you to let 
you know that at some point Debian will likely want to replace liboce in 
the repositories altogether with libocct. FreeCAD, netgen, and deal.II are 
the only dependencies there that I know of; since FreeCAD uses netgen, I've 
already successfully built the first 2 from libocct.

However, I am not familiar with deal.II so my introductory attempt to build 
using libocct didn't work. While I will eventually have some time to look 
at it further, I was hoping that by announcing this in advance someone in 
the deal.II community could take a look before there's any pressure for the 
removal of liboce in Debian.

By the way, the packages are not in Debian Sid yet, but I hope/assume they 
will be soon. For the time being they need to be built from the git 
repository at https://salsa.debian.org/kkremitzki-guest/opencascade.
