Debian's libpoco-dev is falsely marked multi-arch

[Dick Hollenbeck]

I am unable to install libpoco-dev using a multi-arch configuration of apt beyond the install of the first architecture. There are files which are included in more than one arch, so they clash on installation of the second arch.

I discovered this when building hub.docker.com image softplc/toolkit. In order to get multiple archs versions of libpoco.dev on that image, ugly hacks had to be employed.

This should be sent upstream to the maintainer.

Hi Dick,

can you give a list of files that are you think conflict?
Also which Ubuntu version did you use?
Assuming it is not this:

Finally, note that you can't install multiple versions of libpoco-dev at the same time as libmariadb-dev is not Multi-Arch compatible, see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=920365
