| adds68 | Hi there, i'm trying to install buildstream into a virtualenv, when i pull down buildstream, enable site packages and run pip install, i receive an error: | 09:10 |
| adds68 | BuildStream requires OSTree >= v2017.8 with Python bindings. Install it using your package manager (usually ostree or gir1.2-ostree-1.0). | 09:10 |
| adds68 | how do i update OsTree, to this latest version, the OSTree docs lead to a dead github link | 09:11 |

| tristan | adds68, sorry have been in a meeting... which will continue in a moment :-/ | 09:32 |
| tristan | adds68, https://github.com/ostreedev/ostree should be the right place... | 09:32 |
| tristan | hopefully we're going to improve the docker user story very soon, which would help for the moment while we require such a new version of ostree :-/ | 09:33 |
| adds68 | Hi tristan, thanks for the link, i'm a little confused by the "recursive git script" section | 09:33 |
| adds68 | The "this code" link takes me to a 404 page, so should i just download the project as a zip and try and install it from source? | 09:34 |
| tristan | oh weird, I never used that | 09:49 |
| tristan | just init and update the submodules and it builds | 09:49 |
| tristan | adds68, ok so, with a docker image that already contains ostree we wont have this building issue, but yes for now I just build it on my host | 09:50 |
| tristan | One can use an alternative prefix in a home dir, I've added `export GI_TYPELIB_PATH=${prefix}/lib/girepository-1.0` to my .bashrc | 09:52 |
| adds68 | tristan, so should i use the docker image or try and install the latest ostree locally? | 09:55 |
| adds68 | tristan, I'm not too sure what that command is doing above also^ sorry | 09:55 |
| tristan | what is your distro ? | 09:56 |
| tristan | jonathanmaw, do you still use a docker image to build ? | 09:56 |
| jonathanmaw | tristan: I'm not using a docker image, no. | 09:56 |
| tristan | hmm :-/ | 09:56 |
| tristan | I never use docker and dont know enough to confidently guide someone through it | 09:57 |
| adds68 | tristan, i'm running debian stretch | 09:57 |
| adds68 | debian 4.9.30 | 09:57 |
| gitlab-br-bot | buildstream: Tristan Maat created branch 48-incorrect-pipeline-total-element-count-for-bst-track | 09:57 |
| tristan | Me too :) | 09:57 |
| adds68 | If i can compile and install the latest OStree then my python virtualenv should work | 09:58 |
| adds68 | I'm just not clear on how to install it from their docs | 09:58 |
| adds68 | =/ | 09:58 |
| tristan | adds68, Ok that I can help with I think hehe... | 09:58 |
| tristan | So, with debian I believe /usr/local is clean for the user to play with (except for python which is just, really weird) | 09:59 |
| tristan | So I personally just super user install into /usr/local (debian installs ostree directly into /usr) | 10:00 |
| tristan | first of all, git clone https://github.com/ostreedev/ostree | 10:00 |
| tristan | cd ostree | 10:00 |
| tristan | git submodules init | 10:00 |
| tristan | sorry | 10:00 |
| tristan | git submodule init | 10:00 |
| tristan | git submodule update | 10:00 |
| tristan | So, that will give you the latest ostree ready to build | 10:01 |
| tristan | After that | 10:01 |
| tristan | ./configure && make && sudo make install ... would install it into /usr/local | 10:01 |
| tristan | And, you need to have the line: export GI_TYPELIB_PATH=/usr/local/lib/girepository-1.0 | 10:02 |
| tristan | in your .bashrc (to make sure it keeps working) | 10:02 |
| tristan | adds68, that by itself should be enough | 10:02 |
| adds68 | Excellent, thanks very much :) i shall try these steps and see how far i get | 10:02 |
| tristan | Afaics, I'm using debian's packaged bubblwrap without issue | 10:02 |
| adds68 | Could explain what GI_TYPELIB_PATH is | 10:03 |
| adds68 | ?* | 10:03 |
| tristan | adds68, sure, we use ostree via the gobject introspection bindings for python | 10:03 |
| tristan | So thats "GObject Introspection" typelib path | 10:03 |
| tristan | The typelibs is a thing (a binary) that C libraries install, to allow foreign languages to easily call into the C library basically | 10:04 |
| adds68 | tristan, ahh ok so GObject allows you to call Ostree from python? | 10:05 |
| *** jonathanmaw has quit IRC | 10:06 | |
| tristan | the "python3-gi" distro package which is needed specifically... is to let python interact with libraries which provide GObject introspection data | 10:06 |
| tristan | adds68, basically yes :) | 10:06 |
| adds68 | Thanks tristan, i suspect many more questions will arise, but it all sounds very interesting | 10:07 |
| tristan | I hope it doesnt take too much effort to get off the ground :) | 10:08 |
| *** jonathanmaw has joined #buildstream | 10:08 | |
| tristan | fwiw I think next week we'll have someone looking into making the docker approach easy | 10:08 |
| adds68 | tristan, would the docker image be a sort of "playground" or an actual install to use locally? | 10:13 |
| tristan | it should let you run buildstream locally without having to install the requirements on your machine itself | 10:15 |
| tristan | with a script that makes it kind of transparent | 10:15 |
| tristan | I guess similar to activating a venv | 10:15 |
| adds68 | tristan, have you looked into Pipenv? | 10:16 |
| adds68 | tristan, https://pipenv.readthedocs.io/en/latest/ | 10:16 |
| tristan | adds68, that looks like its part of the whole misguided packaging approach from hell that is prevailant in python yeah :) | 10:17 |
| adds68 | tristan, hahahaha, it's a neat way of managing a virtualenv install though | 10:18 |
| tristan | it wouldnt do better than a venv anyway, it will assume that the whole world is written in pure python, and everything you could possible need is in /usr/lib/python{version}/ :) | 10:18 |
| * adds68 is still very new and naive :P | 10:18 | |

| adds68 | I have ostree installed running v2017.12, yet the buildstream pip install is still complaining that my version is not up to date? | 16:05 |
| adds68 | Processing /home/adamjones/buildstream | 16:05 |
| adds68 | Complete output from command python setup.py egg_info: | 16:05 |
| adds68 | OSTree not found | 16:05 |
| adds68 | BuildStream requires OSTree >= v2017.8 with Python bindings. Install it using your package manager (usually ostree or gir1.2-ostree-1.0). | 16:05 |
| adds68 | 16:05 | |
| adds68 | ---------------------------------------- | 16:05 |
| adds68 | Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-ap1jk9fk-build/ | 16:05 |
| tlater | Do you also have an up-to-date gir1.2-ostree-1.0 installed? | 16:22 |
| tlater | adds68: Sorry, slow | 16:22 |
| adds68 | hi tlater, yes i do | 16:22 |
| adds68 | I've looked into the setup.py and run the import statement where it fails in a python shell and the import works? | 16:23 |
| adds68 | So i'm not sure why setup.py is failing? | 16:23 |
| tlater | Including the bit where it checks what version ostree reports? | 16:24 |
| tlater | python3/python2? | 16:25 |
| adds68 | tlater, python3 ahh sorry it seems to be this line that is failing | 16:25 |
| adds68 | try: | 16:26 |
| adds68 | 67 gi.require_version('OSTree', '1.0') | 16:26 |
| adds68 | 68 from gi.repository import OSTree | 16:26 |
| adds68 | 69 except: | 16:26 |
| adds68 | 70 exit_ostree("OSTree not found") | 16:26 |
| tlater | That looks like you don't have gir1.2-ostree-1.0 | 16:26 |
| adds68 | I've just run those commands inside ipython and again no errors? | 16:27 |
| adds68 | I can import OSTree and tab complete on the commands etc | 16:27 |
| adds68 | Python 3.5.3 | 16:28 |
| tlater | Hm. Do you run python in a fancy way since you manually compiled those packages? | 16:28 |
| adds68 | tlater, no i just installed python from apt-get | 16:29 |
| adds68 | created a virtualenv using my default python3 and then run tried to run setup.py | 16:29 |
| tlater | Do you run the python shell in the same virtualenv? | 16:29 |
| tlater | When you try those commadns? | 16:30 |
| adds68 | yea i activate the env, then navigate to buildstream dir | 16:30 |
| adds68 | Yep, ipython is running inside my buildstream env | 16:30 |
| tlater | That's... Strange. | 16:30 |
| adds68 | IKR :( | 16:31 |
| tlater | Can you run the setup.py from within ipython? | 16:31 |
| * tlater is not entirely sure what sorcery would be required for that, probably an import | 16:31 | |
| adds68 | ttributeError: 'gi.repository.OSTree' object has no attribute 'YEAR_VERSION' | 16:32 |
| adds68 | trace back from ipython | 16:32 |
| tlater | That means it's outdated | 16:32 |
| tlater | Though it should report an exception first... | 16:33 |
| tlater | Did you have ostree installed before building it manually, and if yes, is that package/gir1.2-ostree-1.0 perhaps still installed? | 16:33 |
| adds68 | Yea, i tried following the suggested package manager steps | 16:34 |
| adds68 | but i removed it after installing manually, so should i try and remove gir1? | 16:34 |
| tlater | Ah, yes, you'll have to remove git1.2-ostree-1.0 and then build that from source | 16:34 |
| tlater | That's what I meant earlier | 16:35 |
| tlater | Should be a bit easier as it's a python package, but again, I just installed an unstable package so not entirely sure if you'll need to manually build gobject-introspection or something. | 16:36 |
| adds68 | if this doesnt work, i'll just try and follow the sid way | 16:37 |
| adds68 | Why the stable package so out of date? | 16:37 |
| tlater | Because *stability* ;P | 16:38 |
| adds68 | i cant find where i would get package/gir1.2-ostree-1.0 to compile again from source | 16:58 |
| adds68 | so i'm just going to remove this and installed from sid in the morning | 16:58 |
| tristan | Do you have GI_TYPELIB_PATH set in your environment like I recommended ? | 17:00 |
| tristan | when running setup.py ? | 17:00 |
| tristan | adds68, you installed gir1.2-ostree-1.0 or whatever, when you built and installed ostree (or, maybe building ostree didnt build gobject introspection data if you didnt have gobject-introspection devel package available when you built ostree) | 17:02 |
| tristan | but make install should have given you ostree stuff inside /usr/local/lib/girepository-1.0 | 17:03 |
| tristan | the end of the ./configure output of ostree will tell you if GObject Introspection was enabled for the build | 17:03 |
| tristan | if not, it needs to be built with gobject introspection devel package available on your system | 17:03 |
| * tlater completely misunderstood how ostree was packaged, sorry adds68 | 17:08 | |
