This is the *very* reason for which -dev packages shouldn't contain the
soversion...


Given that you are using cowbuilder, which respects the alternative
build-dependencies, just put the all separated by |, in the meantime hoping
they will become unversioned in the future.

Re: build-depends for different distro releases

[Dan Kegel]

I put 'em all on separate lines so I can add comments;
my control tends to look like this for packages that build on multiple
versions of ubuntu:

Build-Depends: debhelper (>= 7),
# libpng12-dev for ubuntu 16.04, libpng-dev for ubuntu 17.10 and up
   libpng12-dev | libpng-dev,
   libvtk6-dev | libvtk5-dev,
...

It's a fragile approach, but works well enough here.  Sometimes I have
to add version
specifiers or depend on proxy packages just to test which platform.  Ugh.

build-depends for different distro releases

[Daniel Sperka]

   I'm updating the packaging for a software package for debian and ubuntu
(via neurodebian). The src package will build (using cowbuilder) under
ubuntu xenial and debian jessie.

   Under stretch, the build fails while updating build-deps:

 pbuilder-satisfydepends-dummy :
 Depends: libvtk5-dev which is a virtual package and is not provided by
any available package
 Depends: libpng12-dev which is a virtual package and is not provided
by any available package

   It seems that under stretch, libvtk5 has been replaced by libvtk6, and
libpng12 by libpng16.

   How can I express this in a single control file? In other words, my
control file has the following (which works under debian/jessie and
ubuntu/xenial):

Under xenial/jessie the following is in debian/control:

Build-Depends: debhelper (>= 5), libqt4-dev (>= 4.3), libqt4-opengl-dev |
libqt4-dev (<< 4.4.0), libqwt5-qt4-dev, libvtk5-dev, libminc-dev,
libqtassistantclient-dev, libpng12-dev, cmake

It seems that I need to have this line be different under debian/stretch:

Under xenial/jessie the following is in debian/control:

Build-Depends: debhelper (>= 5), libqt4-dev (>= 4.3), libqt4-opengl-dev |
libqt4-dev (<< 4.4.0), libqwt5-qt4-dev, libvtk6-dev, libminc-dev,
libqtassistantclient-dev, libpng16-dev, cmake
