[Debian-med-packaging] Bug#1145354: gdcm: FTBFS with swig 4.5.0

[Rafael Laboissière]

Source: gdcm
Version: 3.0.24-13
Severity: serious
Tags: ftbfs sid forky
Justification: Policy 4.9
User: rafael at debian.org
Usertags: swig-4.5.0

Dear Maintainer,

The gdcm package FTBFS with swig 4.5.0, which is currently in unstable. An excerpt of the build log is shown below.

This is due to the removal of the Python 2 compatibility macros in version 4.5.0. According to the SWIG authors, these macros were retained in the generated code (pyhead.swg) solely for user typemaps. Any typemap using these macros must be updated to call the Python 3 C API directly.

Best,

Rafael Laboissière
