OpenPegasus is being developed and maintained under the auspices of The Open Group. OpenPegasus is maintained under the license defined in the doc directory of this release. The specific file is: pegasus/doc/license.txt. This licensing is intended to support as wide a distribution as possible with minimal demands on the users.
More information on this project, access to the CVS, and documentation is available from the OpenPegasus web site.
Note
that all references in this readme to files in the OpenPegasus source
tree are of the form pegasus/..., where "pegasus" is the top-level
directory and also the name of the OpenPegasus module in CVS.
CVS write accounts are managed by Martin Kirk of The Open Group (m.kirk@opengroup.org)
OpenPegasus is regularly tested against a
variety of platforms by the
development group. The results of the nightly tests can be found
here on our Nightly
Build and Test Status page. The Release Notes provide
additional details
regarding the platforms.
PEP 287 contains the Release Notes for the 2.6.0 release.
We have worked to minimize the dependence of OpenPegasus on other software packages and tools. Currently OpenPegasus has the following dependencies:
NOTE:
A set of the required
tools for building on the Windows platform is available on the
OpenPegasus Tools
web page.
The manpages for each of the commands are in the pegasus/rpm/manLinux/ directory (from CVS).
To see simple help for each command,
invoke it with the "--help" option.
Much
of
OpenPegasus
is documented in the Pegasus
Enhancement Process (PEPs) which are the basis for approval of
OpenPegasus functionality, changes, plans, etc. The approved PEPs
are publicly available on the OpenPegasus web site.
Other documentation available is an api document (creatable from the source tree, see pegasus/doc/apidoc) and other miscellaneous documentation in the doc directory. Also, there is a set of Release Notes for each release in the pegasus root source directory of CVS.
Note that the OpenPegasus web site will be the source of most documentation in the future, and today is the source of most discussion and design documentation.

Refer to the Availability
section for instructions on obtaining source code.
If you want to install pre-built Pegasus
executables instead of building from source code, then refer to the RPM installation instructions.
Before
you build, install, or run OpenPegasus, be sure you have the proper set
of software
it depends on. Refer to the section Dependencies
for
the complete list.
Before building, installing, or running
OpenPegasus, some environment variables may
have to be defined or updated. See PEP 277 for the full list of
environment variables and configuration options for OpenPegasus. The
minimum set is:
Before using OpenPegasus you must populate the repository. Typically,
this
is done during the build process by the 'make repository' target. However,
you
can also compile MOF (Managed Object Format) code manually with the
cimmof compiler.
The 'make repository' target in pegasus/Makefile does several things:
OpenPegasus registers Providers using a set of provider registration classes encoded in MOF. This set of classes is close to, but not exactly the same as, the experimental DMTF definition (See the DMTF Interop schema, experimental versions starting with 2.6). This will be harmonized in the future when the DMTF schema is moved to final status.
Registration is performed by creating instances of the registration classes that represent the provider module, providers, capabilities, etc. to be registered. The easiest way to create a new registration today is to copy from one of the existing registration MOFs. See the src/Providers/sample/Load directory for examples of several registration instance implementations that do work with OpenPegasus today.
To build OpenPegasus on Linux, ensure that you you have the necessary
environment
variables set (eg. PEGASUS_HOME, PEGASUS_ROOT, PEGASUS_PLATFORM).
For
32 bit linux, the definition of PEGASUS_PLATFORM is normally
LINUX_IX86_GNU. Use the g++
compiler to compile and link the executables.
Use of Windows 2000 SP3 or later is recommended. OpenPegasus is regularly tested on both Windows 2000 and Windows XP using the Microsoft Visual C++ compilers.
Today we build OpenPegasus on Windows using a set of Makefiles contained in the source distribution, the Microsoft compilers (DevStudio 5.x is not supported, Visual Studio 6.0 (SP5) or later is supported) and the GNUMAKE make utility. Note that you MUST have the OpenPegasus mu.exe utility compiled and available before trying to compile OpenPegasus on the normal windows platform. The following is the basic setup steps for the environment.
Setup the environment variables and path for the Micrososft Visual C compiler. Typically this can be done by running the VCVARS32.BAT file supplied with Microsoft Visual C++. (contained in the same directory as cl.exe).
For Windows, try the following for an example environment:
REM call the standard Microsoft .bat for VC 6 setup.
call 'C:/Program Files\Microsoft Visual Studio\VC98\Bin\Vcvars32.bat'
REM Set debug to something if you want to compile in debug mode
set PEGASUS_DEBUG=true
REM set PEGASUS_ROOT to top of source tree
set PEGASUS_ROOT=C:/cimom/pegasus (Note: The '/' characters are intentional and required by the OpenPegasus build system)
REM set PEGASUS_HOME to where you want repository and executables, it can be the same as PEGASUS_ROOT
set PEGASUS_HOME=%PEGASUS_ROOT%
REM set PEGASUS_PLATFORM for Windows
set PEGASUS_PLATFORM=WIN32_IX86_MSVC
REM setup the path to the runtime files.
set path=%path%;%PEGASUS_HOME%\bin
In order to provide a consistent build structure across multiple platforms, we developed a utility to provide a consistent set of functions across these platforms. The MU utility is a simple utility that contains many commands. For example:
C:\> mu rm myfile.cpp yourfile.cpp
You may type "mu" to get a list of valid commands. Here are some of them:
rm, rmdirhier, mkdirhier, echo, touch, pwd, copy, move, compare depend
The MU utility supports globing (expansion of wildcards) so you can do things like this:
C:\> mu rm *.obj *.exe
MU is required to build under the Windows
environment. MU is
available as part
of the distribution of OpenPegasus.
To build with SSL you need the OpenSSL libraries and header files. They
are NOT distributed with OpenPegasus. Make sure you have them in a
standard
directory so OpenPegasus can find them. If that's not
the case, set the environment variable OPENSSL_HOME= to point where
your OpenSSL
installation is (refer to PEP 277
for more details on build variables).
You must also have the PEGASUS_HAS_SSL variable defined. Then when you build OpenPegasus, it will include the SSL support.
OpenPegasus includes an extensive set of test facilities as part of the CVS environment, including:
ICU (International Components for
Unicode) refers to the set of
libraries that OpenPegasus uses to run with globalization support. For
example, these
libraries are used
to
load messages in different languages, format currency and numbers
according to
a specific locale etc. In order to enable globalization, OpenPegasus
must be built with ICU enabled, ie. the right environment variables
must be
set prior to running "make". Refer to the GlobalizationHOWTO.htm in the
pegasus/docs
directory for details.
When users run "make servertests"
to verify the integrity of an OpenPegasus download, a series of tests
are
run that
require the CIM Server to be running. These tests currently depend on
specific
messages returned from the CIM Server. When ICU is enabled, all
messages
come from the resource bundles and these usually do not match the
hardcoded default messages within OpenPegasus. These hardcoded default
messages are what the various test programs expect in order to complete
successfully. If the ICU-enabled CIM Server is started without
disabling message loading from the bundles, "make servertests"
will
fail.
In order to run "make servertests"
successfully with ICU enabled, an
environment variable called PEGASUS_USE_DEFAULT_MESSAGES must be
defined
prior to
starting OpenPegasus. Once
this is defined, when OpenPegasus starts,
all
messages generated will be the default hardcoded messages. This will
enable
"make servertests"
to complete successfully. Once "make
servertests"
is
complete, you should stop OpenPegasus and
then undefine
PEGASUS_USE_DEFAULT_MESSAGES. If this variable is left defined,
OpenPegasus
will not be able to load messages
using ICU resource bundles.
When
running the "make unittests"
command with ICU enabled, the PEGASUS_MSG_HOME
environment variable must be set to the home directory where the ICU
resource bundles are built. By default the resource bundles are built
into directories below PEGASUS_HOME/msg, so that should be the setting
for PEGASUS_MSG_HOME.
