We need help with fixing Darwin packages .

|  NixOS Moderation Bot banned @jykrwn_bot:matrix.org (disagreement). | 10:26:51 |
 r-burns | Big closure reduction for lots of geospatial packages that depend on hdf4 (usually via gdal). Would appreciate a review: https://github.com/NixOS/nixpkgs/pull/517513 | 19:20:34 |

 nh2 | I'm adding CloudCompare and Meshlab to the team, please say in case anybody doesn't want that:
- https://github.com/NixOS/nixpkgs/pull/518721
- https://github.com/NixOS/nixpkgs/pull/518723
I am also packaging e57inspector which is extremely useful because in contrast to CloudCompare, it can read E57 metadata without reading the whole file (which can be 100s of GB):

| Ivan Mincik (imincik) | Few packages are still failing to build on Linux
- cloudcompare (cc nh2 )
- folium
- osmnx

| Ivan Mincik (imincik) | Situation on Darwin is much worse | 05:00:00 |

QGIS is failing due to qtwebengine not building after upgrade
| 05:27:28 |
| autra | mmhhh fixing laszip import in cloudcompare is easy enough ("-DLASZIP_INCLUDE_DIR=${lib.getInclude laszip}/include/laszip"), but then it chokes on a type (vector) not found. It's odd because it seems upstream is missing a "std::". Either I'm missing something, or upstream didn't really test building the release with las support | 10:02:35 |
| autra | with laZ support, actually | 10:02:45 |
| autra | what do you think if the geospatial team also adopts ifcopenshell? (tool to read ifc files, containing buildings information, may or may not be georeferenced) | 10:03:43 |
| autra | also the martin upgrade (that you started sikmir ) seems to not be easy :-/ | 10:04:13 |
| autra | ah for cloudcompare, we need https://github.com/CloudCompare/CloudCompare/commit/8e1c0562a7c19fd26ccd0c23bb05fb7c36980e0c | 10:17:44 |
| autra | Adoption of ifcopenshell and cartopy https://github.com/NixOS/nixpkgs/pull/520390 | 10:48:55 |
| autra | cloud compare fix https://github.com/NixOS/nixpkgs/pull/520391 | 10:54:20 |
| nh2 | autra: thank you, merged!
A small request for the future would be to always include name = "cloudcompare-Name-of-the-patch-here.patch"; in fetchpatches so that one can actually see in the download / nix-store -q --tree what the hell that derivation is on which something depends, but I didn't want to block the PR on that | 14:15:09 |
| autra | oh you're right! sorry for missing that | 14:15:41 |
| nh2 | autra: Does that need a 26.05 backport? | 15:05:28 |
| autra | nh2: If I'm not mistaken, release is created from master in like 3 days, so I guess not? | 15:06:26 |
| autra | but I'm not sure of tihs | 15:07:04 |
| Ivan Mincik (imincik) | Great thanks for fixes @autra:trancart.eu | 19:11:47 |

 sikmir | https://github.com/NixOS/nixpkgs/pull/520750 | 08:31:35 |
| nh2 | Makes sense then, I haven't checked the calendar yet | 20:48:43 |
| nh2 | I made deterministic VLM screenshot analysis tests.
I think this can help test GUI applications that are difficult to judge automatically otherwise.
Initially for cloudcompare and e57inspector.
