| RP | mithro: whilst I only have finite time, I am happy to give pointers on specific issues if it would help | 15:25 |
| mithro | RP: Yeah - one big question is requirement checking is a big thing | 15:26 |
| mithro | RP: IE Checking you have Xilinx toolchain and stuff installed | 15:26 |
| RP | mithro: that is basically what sanity.bbclass does for things like git being present and of the right version | 15:27 |
| RP | mithro: bitbake generates events at different parts of the build and you can do pretty much anything in an event handler | 15:27 |
| mithro | RP: This file? https://github.com/openembedded/openembedded/blob/master/classes/sanity.bbclass | 15:29 |
| RP | mithro: yes | 15:30 |
| RP | mithro: its complicated by caching and compatibility porting code to upgrade old builds to new formats, it'd be possible to do something much simpler | 15:31 |
| mithro | RP: What would be an example to check for Xilinx? | 15:32 |
| mithro | RP: Our shell script does this -> https://github.com/timvideos/litex-buildenv/blob/master/scripts/download-env.sh#L165-L266 | 15:32 |
| yann | I can't seem to find why bitbake wants to rebuild a given package, while it takes it from shared-state on another machine (with the same sstate, and that's a pyro-based build) - how can I dig into that ? | 15:35 |
| khem | yann: such cases, usually mean there is some unwanted host dependency that crept into variable references used to calculate sstate hash, you can dump the signatures and compare them bitbake-diffsigs is handy this page might be helpful too https://wiki.yoctoproject.org/wiki/TipsAndTricks/Understanding_what_changed_(diffsigs_etc) | 15:39 |
| yann | thx khem, digging that | 15:40 |

| RP | mithro: INHERIT += "sanity2" in distro config to enable. You'd call your script check-xlinx-toolchain, or you could put a shell function in that class | 15:43 |
| RP | mithro: its made ugly by having the sanity events mechanism to report back problems, really should just mkae that the default and simplfy the code but never got around to that | 15:44 |
| *** khem <khem!~khem@unaffiliated/khem> has joined #yocto | 15:44 | |
| RP | mithro: oh, that code probably needs to give the handler another name so it doesn't clash with sanity.bbclass | 15:45 |
| yann | khem: I'm still not sure that the particular package i'm looking at is not getting rebuilt because one of its deps has been - is there a quick way to check this ? | 15:49 |
| khem | yann: I would suggest to do build from exact metadata on the offending machine then ideally it should not rebuild anything and if it does runinto do_compile tasks then you take the first do_compile task appearing in logs and chase it | 15:52 |
| RP | khem: safe trip back? | 15:52 |
| RP | khem: still here and its still raining :) | 15:52 |
| yann | thx | 15:53 |
| yann | khem: clearing tmp/work should be enough for such a test, right ? | 15:55 |
| khem | yes | 15:58 |
| khem | RP: my flight got cancelled and they let me in because when I was doing security it was not yet cancelled, apparantly I was first one to checkin for that flight, and luckily another flight to SF was delayed and I ran 200m dash to reach there and beg them to put me in that flight luckily I got in and was sitting on last row but yeah reached safely, | 16:00 |
| khem | btw. air canada send me a notice of cancellation and rebooking me to same flight on saturday, and just this morning I got notified that even the saturday flight is cancalled haha | 16:01 |

| khem | yeah, | 16:07 |
| khem | mithro: this is layername which you should find in layer.conf of meta-oe | 16:08 |
| yann | oh, after moving tmp/work away bitbake thinks it can compile ncurses-native without even fetching it - a bit scary :) | 16:08 |

| yann | hm, strange - I could get past the ncurses-native issue when I realized I had recently added a do_install_append for ncurses and omitted to make it class-target. But now (with a clean tmp/work or with my original) it's trying to rebuild gcc-cross-initial-aarch64 without running fetch first | 16:27 |
| RP | yann: gcc recipes are special in that they have a gcc-source recipe to handle the sourcecode | 16:29 |

| yann | even when creating a new build dir (same local.conf so same sstate), its first task ever is gcc-cross-initial_6.4.bb:do_compile, tmp/work isn't even created | 16:35 |
| yann | I probably messed up something, can't see another reason why it would suddently break so badly | 16:36 |

| yann | hm, apparently my immediate problem was that when switching from one build to another just re-sourced oe-init-build-env and some old values are apparently not rewritten | 16:48 |
| yann | so now a brand new build dir decides quilt-native must be compiled, so I now have sigdata for this host - however, the well-behaved one taking artifacts from sstate only has rm_work.sigdata as non-empty - I'm a bit at a loss about what to compare | 17:00 |
| khem | RP: I figured that its because this builders python = python3 but some recipes are expecting python = python2 | 17:21 |

| yann | if I take the sigdata generated by a spurious glic rebuild today, and compare it to the siginfo stored in the sstate (generated on another machine)... bitbake-diffsigs does not see any difference (yet the files have different size) | 19:22 |
| yann | no new sstate was stored for this compile state, which seems to confirm the sstate was here and should have been used, no ? | 19:26 |
