Dear maintainer:

During a rebuild of all packages in unstable, this package failed to build.

Below you will find the last part of the build log (probably the most
relevant part, but not necessarily). If required, the full build log
is available here:

https://people.debian.org/~sanvila/build-logs/202608/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you cannot reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:kicad, so that this is still
visible in the BTS web page for this package.

Thanks.

Hi,

The current bug is due to the removal of the Python 2 compatibility macros in version 4.5.0 of SWIG. [1]

According to the SWIG authors, these macros were retained in the generated code (pyhead.swg) solely for user typemaps. All typemap using these macros are updated to call the Python 3 C API directly.

Please note that the kicad uptream authors removed the Python bindings in commit 65a442b1 [2]. This is planned for version 11 of kicad, which is currently in development. [3]

I have submitted a patch to fix the bug in the form of a merge request to the package repository at Salsa [4]. You might want to merge the commit in the meantime to resolve the FTBFS issue for version 10.x of KiCAD.

Best,

Rafael Labossisère
