[Debian-med-packaging] Bug#557495: [treinen at free.fr: Bug#557495: libtowitoko-dev and libctapimkt0-dev: error when trying to install together]

[Andreas Tille]

Hi,

I realised that there are all in all three packages in Debian which
are acceccing a CT-API and providing a file ctapi.h:

$ apt-file search ctapi.h
libctapimkt0-dev: /usr/include/ctapi.h
libopenct1-dev: /usr/include/openct/ctapi.h
libtowitoko-dev: /usr/include/ctapi.h

While libopenct1-dev uses a subdirectory and thus does not create
a conflict to the other two I wonder how to solve this conflict
reasonably.  The upstream author of libctapimkt0 told me that in
principle ctapi.h would have the same content and thus all libraries
might be able to share the same file.  If this is true this would
IMHO the best solution - the only remaining question would be from
which source this file should be taken and into which common
devel package it should go to enable the other package depend from
it.

The other solution would be to move libctapimkt0-dev header files into a
subdirectory or if this makes no sense to simply conclict with
libtowitoko-dev - but I have no idea whether this is reasonable or
needed.

I admit I have no idea about this CT-API at all and really need to relay
on your expertise in this question.  For me ths current solution looks
quite confusing and it should be solved in a reasonable way.

Kind regards

       Andreas.
