[Debian-med-packaging] Bug#907819: jellyfish: FTBFS randomly (ld: cannot find -ljellyfish-2.0)

[Santiago Vila]

Package: src:jellyfish
Version: 2.2.8-3
Severity: serious
Tags: ftbfs

Dear maintainer:

I tried to build this package in sid and it failed with this error:

--------------------------------------------------------------------------------
/usr/bin/ld: cannot find -ljellyfish-2.0
collect2: error: ld returned 1 exit status
error: command 'x86_64-linux-gnu-g++' failed with exit status 1
--------------------------------------------------------------------------------

I'm building on amd64 and this error happens randomly for me
(sometimes it fails, sometimes it does not), but it happened at least
once in the official autobuilders in another architecture:

https://buildd.debian.org/status/fetch.php?pkg=jellyfish&arch=powerpc&ver=2.2.8-3&stamp=1531093335&raw=0

so it seems that the error is not architecture-specific and we can
assume it will also fail randomly on the official buildds too.

I've put all my failed build logs (buster and sid) here:

https://people.debian.org/~sanvila/build-logs/jellyfish/

(but some of those failures are not linking failures).

If this is really a bug in one of the build-depends, please use
reassign and affects, so that this is still visible in the BTS web
page for this package.

Thanks.
