Bug 1197488

I think that the package
    https://admin.fedoraproject.org/pkgdb/package/cppad/
provides all the necessary functionality.

There may be an two issue here. 

1. CppAD, as configured for Fedora, does not test its use with Ipopt, because it does not need to depend on Ipopt. If Ipopt is present in the system, it is possible to build and run the CppAD Ipopt tests.

2. There is a deprecated cppad_ipopt object library that I do not think is being used by coin.

I think we should begin by just trying to use the current fedora / redhat install of CppAD to build the other coin packages that depend on it. If there are problems with this, then we can consider how to proceed.

I mean at first, but most cosmetically add extra provides:

$ rpm -q --provides cppad-devel
cppad = 20150000.4-3.fc22
cppad-devel = 20150000.4-3.fc22
pkgconfig(cppad) = 20150000.4

to also have:

coin-or-cppad = 20150000.4-3.fc22
coin-or-cppad-devel = 20150000.4-3.fc22


I can check what packages may use cppad, AFAIK none
has it as a "hard" requires.

About Ipopt, there is an issue, rooted at MUMPS where
there are two coin-or-Ipopt runtimes, one using
openmpi (parallel) and one not using it (serial).
For the coin-or-* packages that require Ipopt, I
added a build time option to use either, but
defaults to the serial one, for example, see the
with_mpi macro in
http://pkgs.fedoraproject.org/cgit/coin-or-Bonmin.git/tree/coin-or-Bonmin.spec

So you are suggesting that I add the following lines to the cppad spec file ?
    Provides: coin-or-cppad%{version}-%{release}
    Provides: coin-or-cppad-devel%{version}-%{release}

I think I have made the changes you requested. See the changes to cppad.spec in
http://pkgs.fedoraproject.org/cgit/cppad.git/commit/?id=ab35867f883d9fa854d3f1ab78e90f4741fa9610

Hi Brad,

Sorry for only today going to get back on this, while
working on updating, and new coin-or packages...
But the change was incorrect, the lines should be added
to the cppad-devel package, not to the empty cppad
"metapackage" package.

$ rpm -q --provides cppad-devel
cppad = 20150000.9-1.fc23
cppad-devel = 20150000.9-1.fc23
pkgconfig(cppad) = 20150000.9

$ rpm -q --changelog cppad-devel | grep coin-or
- 3: Add Provides coin-or-cppad.
- https://projects.coin-or.org/CppAD/changeset/1698
- https://projects.coin-or.org/CppAD/changeset/1664
- Change download directory to standard coin-or location.

Cut&paste of the diff that would work.

I think I have done as requested; see
http://pkgs.fedoraproject.org/cgit/cppad.git/commit/cppad.spec?id=5a2fbeade281c94f7ffbd5a11a70ba3f38e0e34d

I downloaded the packages from koji (was not yet in mirrors),
"rpm -Fvh" them, and now it works as expected:

$ sudo rpm -Fvh ~/Downloads/cppad-d*

Nothing to do.
Complete!

I would like make sure that this works the way that CppAD is used by the rest of the coin packages. The normal system install of CppAD puts cppad.hpp in
   /usr/include/cppad/cppad.hpp
I am worried that the coin packages are expecting it to be in
   /usr/include/coin/cppad/cppad.hpp

I think it did just work. As far as I remember, coin-or-OS
(Optimization Services) has a hard requires on CppAD, and
it is building fine, so I suppose it is a good enough
directory, that coin-or-OS finds in in configure.

Just in case you use this with an older version that rawhide,

I pushed the change to the f22 branch; see
http://koji.fedoraproject.org/koji/taskinfo?taskID=9464332

and the f21 branch; see
http://koji.fedoraproject.org/koji/taskinfo?taskID=9465472

Just to confirm as well :)
