[pkg-netfilter-team] Bug#947176: libiptc.pc non-functional

[Michael Biebl]

Package: libip4tc-dev
Version: 1.8.4-1
Severity: serious

Hi,

for some background, see the related bug report
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=946149#10

libiptc.pc was moved from libiptc-dev to libip4tc-dev and
libiptc-dev is now an empty dummy package (which is scheduled to be
removed).

I think this move was incorrect.

The libiptc-dev package should remain and continue shipping libiptc.pc.
The libiptc-dev package should continue to depend on libip4tc-dev and
libip6tc-dev.
I assume moving the header files from libiptc-dev to libip4tc-dev is
find though.

So, why should libiptc-dev remain?

libiptc.pc contains:
Requires:      libip4tc libip6tc

So, for libiptc.pc to be functional, libip4tc-dev and libip6tc-dev need
to be installed.
Making libip4tc-dev depend on libip6tc-dev doesn't really make sense. If
you do that, you can just as well merge libip6tc-dev and libip4tc-dev
into a single libiptc-dev package which contains all development files.

We basically have two sensible options:

1/ Have a single libiptc-dev package which contains all development files
2/ Have a libip6tc-dev package which contains all development files
related to libip6tc, have a libip4tc-dev package which contains all
development files related to libip4tc and have libiptc-dev (convenience)
package which contains libiptc.pc and depends on both libip6tc-dev and libip4tc-dev


The current setup breaks packages which have a pkg-config check for
libiptc, like systemd:
