Package: src:python-demgengeo
Version: 1.4-7
Severity: important
Tags: sid forky ftbfs
User: debian-devel at lists.debian.org
Usertags: boost1.90

Dear Maintainer,

python-demgengeo FTBFS with boost 1.90. Note that the FTBFS may not necessarily be
connected to boost - please check the build log for the actual cause.

Ubuntu has started the rebuild and the status can be tracked here:
https://transitions.ubuntu.com/html/boost1.90.html#!good,bad,partial,unknown,!notintesting
Thanks to them. Please find your package there, after that you can see the logs from
the failing build.

Note: This ticket severity will be increased to RC bug when
boost-defaults is switched to 1.90.

Additional information: The boost system library was removed upstream in 1.89 and is empty since 1.69.
If your package depends on or build-depends on libboost-system-dev, remove it from
build-depends and the build system. See https://www.boost.org/releases/1.89.0/ for cmake instructions.

Note that libboost-system-dev is "virtually" provided by libboost-dev_1.90,
but it is better to drop it from build-depends as this will be removed in the future.


Here is the most probably relevant part of the failing build log:
