Hi fellow cctbx developers, unless I am missing something, nobody has written a “setup.py” to install the cctbx with distutils in Python standard site-packages? If so, I am planning to contribute one as this would make it easier for us at Bruker. I am just asking in case I would duplicate existing work. Best wishes, Luc
Luc Not aware of anyone who has done it, but I have met about 10^4 people who think this would be *a good thing* so please keep us posted on progress; I have met people for whom this is a reason *not* to use cctbx Thank you in advance :) Graeme -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Luc Bourhis Sent: 09 May 2016 09:26 To: cctbx mailing list Subject: [cctbxbb] Installation with distutils?

Hi Graeme,
Not aware of anyone who has done it, but I have met about 10^4 people who think this would be *a good thing* so please keep us posted on progress; I have met people for whom this is a reason *not* to use cctbx
Yes, I have had the same experience too.
Thank you in advance :)
So first thing is to sort out the dependencies. I have just noticed that ccp4io_adaptbx does not feature any licence. Since it needs to be distributed along with ccp4io, boost and scons to get a distro which can be installed with distutils out of the box, can I add the usual BSD licence to ccp4io_adaptbx?
Hi Luc, this would be a great thing to have, could you write more about your plans? I guess you'll wrap the existing scons-based build system rather than starting from scratch? How are you going to implement "setup.py install"? We considered adding setup.py here, but I thought it's not worth the effort and it won't work well anyway. I'd like to be proved wrong. My thinking was that - redoing everything without scons is a lot of effort for little benefit, and it would quickly get out-of-sync with the main build system if it's not actively maintained - wrapping cctbx/scons build system won't work well because distutils options won't map well to the scons options. And additional layer of indirection would be confusing. I mean distutils-like system that doesn't really work like distutils could be more frustrating than having to explicitly use cctbx build commands. But maybe I'm wrong here. Marcin
Hi Marcin, I will indeed just wrap up our beloved configure and build steps within setup.py. My plan is to install the following hierarchy: site-packages |—— cctbx_distro | |—— cctbx_build | |—— cctbx_project |—— cctbx.pth where cctbx.pth would contain cctbx_distro/cctbx_build/lib cctbx_project/boost_adaptbx cctbx_project/libtbx/pythonpath Finally, I would add to site-packages/sitecustomize the following: import os; os.environ[‘LIBTBX_BUILD’] = path/to/site-packages I just need to refresh my mind about how to get at those paths!

Total agreement here.

I do not plan to support the wealth of setuptools command-line options, like building in place, or creating those fancy development installation. But 99% of the time people are just interested in % python setup.py install so I think there is a case for providing that. That would be the first milestone. The second milestone would be to make sure the cctbx can then be installed with easy_install or pip, which may require a bit more support for the arcanes of setuptools. I don’t think it will be inordinately difficult. Best wishes, Luc
