libipopt not compiled against MUMPS as claimed

[Zach Harris]

Binary package hint: coinor-libipopt0

The following bug:

    http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=590434

was addressed in Debian but apparently (from what I can tell) not in Ubuntu. When I try to use ipopt with Maverick I get:

    Exception of type: OPTION_INVALID in file "IpAlgBuilder.cpp" at line 360:
     Exception message: Selected linear solver MUMPS not available.

The source code reveals that this error can only occur if the compiler macro COIN_HAS_MUMPS was undefined at compile time. However, "aptitude show coinor-libipopt0" (again, in Maverick) says:

      The Debian package is compiled against MUMPS (as it is the only one of the available solvers that is Free Software and included in Debian).

Also, libmumps-seq-4.9.2 is provided as a dependency of coinor-libipopt0. It seems that someone simply failed to ensure that COIN_HAS_MUMPS was configured correctly when libipopt was compiled.

  Incidentally, in my current Debian (squeeze) installation, ipopt does work correctly with the default mumps linear solver.

Also: my Debian machine is 64-bit, just like the reported and closed/fixed case in

    http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=590434.

However, my Maverick VM is 32-bit. So perhaps the problem is not an Ubuntu vs. Debian issue, but rather that the Debian compiler configuration bug (regarding COIN_HAS_MUMPS) was only fixed in the amd64 package, but not the i686 package.

The Natty i386 coinor-libipopt0 package works for me. So the failure to have compiled with COIN_HAS_MUMPS seems just to belong (as far as my experience goes) to the Maverick (and earlier?) i386 binary.

Marking as Fix Released because the problem is resolved in Natty.
