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:xraylib, so that this is still
visible in the BTS web page for this package.

Thanks.

This issue is caused by 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.

I submitted a patch for fixing the issue as a merge request at Salsa [2]. It was taken from the upstream Git repository (commit 09dcb897 [3]). This commit is included in the newest upstream release 4.3.0, so it should also be possible to get rid of the FTBFS bug by upgrading the Debian package.

Best,

Rafael Laboissière
