%description

Dyninst is an Application Program Interface (API) to permit the insertion of
code into a running program. The API also permits changing or removing
subroutine calls from the application program. Run-time code changes are
useful to support a variety of applications including debugging, performance
monitoring, and to support composing applications out of existing packages.
The goal of this API is to provide a machine independent interface to permit
the creation of tools and applications that use run-time code patching.

%package doc
Summary: Documentation for using the Dyninst API
Group: Documentation
%description doc
dyninst-doc contains API documentation for the Dyninst libraries.

%package devel
Summary: Header files for compiling programs with Dyninst
Group: Development/System
Requires: %{?scl_prefix}dyninst = %{version}-%{release}
Requires: boost-devel
Requires: tbb-devel

%description devel
dyninst-devel includes the C header files that specify the Dyninst user-space
libraries and interfaces. This is required for rebuilding any program
that uses Dyninst.

%package static
Summary: Static libraries for the compiling programs with Dyninst
Group: Development/System
Requires: %{?scl_prefix}dyninst-devel = %{version}-%{release}
%description static
dyninst-static includes the static versions of the library files for
the dyninst user-space libraries and interfaces.

%package testsuite
Summary: Programs for testing Dyninst
Group: Development/System
Requires: %{?scl_prefix}dyninst = %{version}-%{release}
Requires: %{?scl_prefix}dyninst-devel = %{version}-%{release}
Requires: %{?scl_prefix}dyninst-static = %{version}-%{release}
Requires: glibc-static
%description testsuite
dyninst-testsuite includes the test harness and target programs for
making sure that dyninst works properly.
