Bug#713592: timemachine: FTBFS: ld: main.o: undefined reference to symbol 'pow@@GLIBC_2.2.5'

[David Suárez]

Source: timemachine
Version: 0.3.3-1
Severity: serious
Tags: jessie sid

Justification: FTBFS on amd64

Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

Maybe you need to add explicitly the offending lib to LD flags.

Relevant part:

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
