%description
CSDP is a library of routines that implements a predictor corrector
variant of the semidefinite programming algorithm of Helmberg, Rendl,
Vanderbei, and Wolkowicz.  The main advantages of this code are that it
is written to be used as a callable subroutine, it is written in C for
efficiency, the code runs in parallel on shared memory multiprocessor
systems, and it makes effective use of sparsity in the constraint
matrices.

%package devel
Summary:        Header files for CSDP
Group:          Development/Libraries
Requires:       %{name}%{?_isa} = %{version}-%{release}

%description devel
This package contains the header files necessary to develop programs
that use the CSDP library.

%package tools
Summary:        Command line tools for working with CSDP
Group:          Applications/Engineering
Requires:       %{name}%{?_isa} = %{version}-%{release}

%description tools
This package contains command-line wrappers around the CSDP library,
including a solver, a program for computing the Lovasz Theta number of a
graph, and some graph manipulation programs.

Note that "csdp-" has been prefixed to some of the binary names, due to
the generic nature of the names.

%package octave
Summary:        Octave interface to CSDP
Group:          Applications/Engineering
Requires:       %{name}-tools = %{version}-%{release}, octave
BuildArch:      noarch

%description octave
This package contains an Octave interface to the C library for
SemiDefinite Programming.

%build
# We can't use the shipped build system.  First, a static library is built,
# but we want a shared library.  Second, parallel make is broken; there are no
# explicit dependencies between subdirectories.  Third, the CFLAGS need to be
# altered in various more-or-less drastic ways.  Fourth, the existing makefiles
# link all binaries with the entire set of libs, but not all binaries need all
# libs.  We build by hand to contain the pain.
