I would not waste more time on this; the bit that requires LiE is only
a very small part of the total functionality, and this dependency will
go away in 2.x anyway. Just disabling that test is fine with me.

Weird, this test went through fine on a VM which I installed from
scratch with Debian 8.6 and then upgraded to testing.

As this test depends on the 'lie' program, it may well a be a problem
in the interaction with that package. For the time being, I am fine
with disabling this specific test for Debian testing.

I have tagged the github repo with 1.46; have left the test active
there.

I have finally had the time to install Debian Testing and fix the
remaining issues. Version 1.46 is on github.com/kpeeters/cadabra now,
and builds/tests without issues with gcc-6.

Many thanks to all for helping out with this. Axel, it would be much
appreciated if you can still push this into the next stable.

Cheers,
Kasper

An 'apt-get update' and 'apt-get dist-upgrade' still does not bring me
6.2.x. Do I need to do anything else to get it on testing?

Hi Axel,

I have just tried building cadabra 1.45 on a fresh install of Testing,
so that's with gcc 6.1.1 (not using the pbuilder, but direct on the
hardware). No problem. Any idea why it doesn't build on your machine
but does on mine?

Cheers,
Kasper

Shouldn't be too difficult to fix, but I'll need a Debian install here
to be able to play. Tried 'testing' in a VirtualBox this weekend but
that just boots to a black screen. What's the best/recommended way to
get gcc6 on a Debian 8.6 system?

Cheers,
Kasper

Sorry, forgot to push the tags, now done.

I have now fixed all compilation issues with recent libraries and
compilers in 1.45, available from http://github.com/kpeeters/cadabra.
This one builds and works on Ubuntu 16.04 with gcc 5.4.0.

If any of you could bring this back to life in Debian, that would be
much appreciated!

Cheers,
Kasper

I haven't had a chance to test this with gcc 5 or 6 yet though; it may
need a bit of further tweaking for those compilers. It will not work
with clang (will fail somewhere else with issues which I solved for 2.x
but do not want to backport for lack of time).

Bug#808634: cadabra: FTBFS: manipulator.hh: fatal error: sigc++/object.h: No such file or directory

[Kasper Peeters]

Author here. Replacing

  #include 

with

  #include 

in src/manipulator.hh solves the problem without changing the
dependencies. I have pushed 1.44 to the github repository
at http://github.com/kpeeters/cadabra .

If anyone can bring this back to life, that would be much 
appreciated.

Bug#574232: cadabra: package purge (after dependencies removal) fails

[Kasper Peeters]

Thanks for reporting that. The problem is the 'postrm' (and 'postinst')
scripts, which build the TeX ls-R files, but get called much later than
I thought. 

The proper way to fix this is to 

  - remove debian/postrm and debian/postinst
  - add 'dh_installtex' in debian/rules, below 'dh_installman'.

Guerkan, can you make these changes and upload them? Or should this go
through a different channel?

Cheers,
Kasper
