Bug#1065489: mongo-c-driver: FTBFS on armhf: format ‘%ld’ expects argument of type ‘long int’, but argument 4 has type ‘__suseconds64_t’ {aka ‘long long int’}

[Emanuele Rocca]

Source: mongo-c-driver
Version: 1.26.0-1.1
Severity: serious
Tags: ftbfs
User: debian-...@lists.debian.org
Usertags: time-t

Dear Maintainer,

mongo-c-driver fails to build from source on armhf. The failure may be
explained with the build flags introduced for the time64 migration,
which are on by default on armhf:

 -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_TIME_BITS=64 
-Werror=implicit-function-declaration
