Bug#1066487: libgpiv: FTBFS: ../../lib/img.c:939:16: error: implicit declaration of function ‘gets’; did you mean ‘fgets’? [-Werror=implicit-function-declaration]
Source: libgpiv
Version: 0.6.1-7.2
Severity: serious
Justification: FTBFS
Tags: trixie sid ftbfs

Hi,
During a rebuild of all packages in sid, your package failed to build
on amd64.
This is most likely caused by a change in dpkg 1.22.6, that enabled
-Werror=implicit-function-declaration. For more information, see
https://wiki.debian.org/qa.debian.org/FTBFS#A2024-03-13_-Werror.3Dimplicit-function-declaration
Relevant part (hopefully):
