arianepaolaHi HeikoS, I have a question related to https://github.com/shogun-toolbox/shogun/issues/313119:29
arianepaolaDidn't see besser82 around. The rpm package building works if I use a stable version, e.g. 4.1.0 of shogun. I am looking for a way to tell rpmbuild not to complain and build a version from git. There are some of the notes in the ticket.19:30
@HeikoSthis is great!19:31
@HeikoSI dont really understand the problem you have19:32
@HeikoSyou download shogun from git but then get a version mismatch?19:32
@HeikoSmismatch for what?19:32
@HeikoS(I am not an expert on these things btw)19:32
arianepaolaI have a master.cfg working with Ubuntu 16.04, Fedora 23 for source compilation and testing using ninja build and another one for Fedora.19:32
@HeikoS(BTW viktor is on holiday but will be back tomorrow or so)19:32
@HeikoSthat is great news19:33
@HeikoSthese are really helpful steps towards the installation19:33
@HeikoSmaybe check back for björn and viktor for your concrete questions19:34
arianepaolaWhen everything is in place, the last step is to run rpmbuild, but even if I change the spec files, it still does only build for 4.1.0 shogun releases, so that I can't change to any git version.19:34
arianepaolaHeikoS: ok, sure19:34
@HeikoSI see19:34
@HeikoSgood work btw19:34
arianepaolaHeikoS: The other issue to build a Python package, I have it kind of working. I am a bit stuck of how to proceed with cmake.19:35
arianepaolathanks :-)19:35
@HeikoSI know a bit about cmake19:35
@HeikoSso shoot19:35
arianepaolaFor the Python package, I have first tried the following. Run cmake, then I used ninja and ninja installed to a local directory to see the shogun files and everything that would be installed. I got that in a basic python package that it could be installed.19:36
arianepaolaIt is possible to use a wrapper and inject information from cmake into the setup.py file and then copy it into the final location and run python setup.py bdist19:36
@HeikoSarianepaola: I guess that it possible19:37
arianepaolaBut it should be the other way around so that when running python package creation, the package script will call cmake and build everything, that is where I am stuck19:37
@HeikoSwe generate shogun/lib/config.h from cmake19:37
@HeikoSthat is a c++ header that has all the #HAVE_NLOPT etc macros defined19:38
@HeikoSwait not sure I get the problem19:38
@HeikoSso currently you use a wrapper?19:38
arianepaolaI just do as if I would install and then run the Python stuff19:39
@HeikoSI see19:39
@HeikoSso yes it should be the other way around19:39
arianepaolae.g. ninja install to a directory callled ./installed and then package19:39
arianepaolayes19:39
@HeikoSif you say install sklearn, it compiles all sorts of c-code19:39
@HeikoSmaybe look for inspiration there? I know they build at least LibSVM19:39
@HeikoSso they have to call some configure/make at some point from setup.poy19:40
arianepaolaI will look more there19:40
@HeikoSarianepaola: try to share a prototype early btw19:41
@HeikoSand the improve it while it is visible19:41
@HeikoSthis way we can have a look, potentially help, and you work is visible to us19:41
arianepaolaok, btw I am still wondering where I can add the things for the Fedora RPM nightly and buildbot19:41
@HeikoSwhere as in?19:42
arianepaolaViktor said to look in the configs branch19:42
arianepaolathere wasn't anything buildbot related19:42
@HeikoSarianepaola: yeah it is incomplete, viktor will know the answer. I don't think our buildbot configs are public at the moment19:43
arianepaolaThe issue on github has the snippet that makes it work, the rest is configs related to building on Ubuntu and Fedora.19:44
@HeikoSokay19:45
@HeikoSarianepaola: btw we are also looking for general ideas to make shogun installation easier, and input is welcome on this19:45
arianepaolabtw, while figuring things out, I sent a pull request to buildbot19:45
@HeikoSbinary packages are one good way to simplify this obviously19:45
@HeikoSbut building shogun from scratch should also be less confusing19:45
@HeikoSif you have any ideas, let us know19:46
arianepaolarelated to cmake, there is still one thing not working as they have added a cmake wrapper two weeks ago.19:46
@HeikoSwho is "they"?19:46
arianepaolasorry, the buildbot developers added a cmake wrapper in the master branch19:46
arianepaolaFound some issues and sent a PR there.19:47
@HeikoSah I see19:47
@HeikoSarianepaola: hey that is great19:47
@HeikoScan you send me the link?19:48
arianepaolaDo you use ninja instead of make? It was much faster for me vs make -j19:48
@HeikoSarianepaola: never used it in fact19:49
arianepaolait is very very fast!!!19:49
@HeikoSarianepaola: with ccache things are quite fast19:49
@HeikoSdo you have that enabled?19:49
arianepaolayes19:49
@HeikoSok cool, I should check that out19:49
arianepaolatry: cmake -G ninja && ninja all19:49
@HeikoSI wonder how that comes?19:49
@HeikoStrying19:49
@HeikoSCMake Error: Could not create named generator ninja19:50
@HeikoSseems like I should instlal some things ;)19:50
arianepaolaninja scales automatically the number of cpus and I when verifying if there are previous build files it is much faster, maybe it does that also in parallel19:50
arianepaolaSorry, it is: cmake -GNinja19:50
arianepaolacmake -GNinja .. && ninja19:51

arianepaolathis is one from buildbot for the docs19:51
arianepaolahttps://github.com/buildbot/buildbot/pull/208819:51
arianepaolaand I will send another when I find the fix for not loading the  cmake buildbot module in the master.cfg19:52
@HeikoSah i see19:52
@HeikoStrying19:52
@HeikoSwow seems qiuck19:53
arianepaolabtw, I would like to add some of my notes to the Wiki page, e.g. development setup on Ubuntu 14.04 & 16.04 and Fedora 23 with all packages and commands <-- getting started in a few seconds19:53
@HeikoSI see, it is in particular when things are already compiled19:53
@HeikoShttp://hamelot.io/programming/make-vs-ninja-performance-comparison/19:53
arianepaolayes19:53
@HeikoSarianepaola: that would be great, the problem is that github doesnt accept PRs for the WIKI at the momenbt19:53
arianepaolayes19:54
@HeikoSbut if you can edit the files and them post them somewhere, I can feed that in19:54
