        Building the VC++ Windows Configuration Tool
        ============================================

NOTE: this tool is no longer supported. Users wanting a graphical
configuration tool under Windows should instead consider the
wxWindows-based tool, ../wxwin/ReadMe.

The graphical configuration tool can be built using a Developer Studio
project, tools/ecosconfig/standalone/win32/Configtool.dsw
Even if building the host tools from Visual Studio, it is still
necessary to install Cygwin and Tcl 8.x. Additionally, there is a
dependency on either the Microsoft Platform SDK or the Microsoft HTML
Help Workshop. The latter is available at:
http://msdn.microsoft.com/library/tools/htmlhelp/wkshp/download.htm

To prepare the machine for the build, it is necessary to:

1) Set the TCLHOME environment variable to the root of the Tcl
installation. (For example, TCLHOME=C:\tcl) This can be set from the
Enviroment Variables dialog on the Advanced tab of the System
Properties dialog.

2) It is also necessary to add several directories to Visual Studio's
default file search paths. This is set from the Directories tab in the
Options menu.

The following entries will need to be added (full paths are shown for
clarity, the actual path may be different):

        a) Executable Files
                c:\cygwin\bin
        b) Include Files
                c:\tcl\include
                c:\program files\microsoft platform sdk\include _OR_
                c:\program files\html help workshop\include
        c) Library Files
                c:\tcl\lib
                c:\program files\microsoft platform sdk\lib _OR_
                c:\program files\html help workshop\lib

3) The build process as setup by default in the sources available from
CVS is setup to build the host tools on the DOS v:\ drive. If this
drive doesn't exist, it may be preferable to do a "subst v:\ c:\temp"
command from a Windows command shell. This will effectively create a
virtual disk which is located at c:\temp, and the build process will
place all intermediate and build files in this location.
(Alternatively, it is possible to go through the project settings in
Visual Studio and adjust the drive letters manually.)

4) If you have installed a version of Tcl other than version 8.2, it
will be necessary to change the names of libraries linked with the
projects. This can be done by:

a) Selecting "Settings..." on the ChangeLog file in the cdl project in
the Configtool workspace, you will see the custom build step for the
project. At the end of the first line of the custom build step, there
is an option --with-tcl_version=82. Change this value (82) to
correspond to the version of Tcl installed on the machine.

b) Selecting "Settings..." on the Configtool project in the workspace,
you should go to the Link tab in the right-hand pane. In this pane you
will see a line listing all the Libraries with which the project is
being linked. Change the tcl82.lib entry to the name appropriate for
the version of Tcl installed.

(NOTE: These settings must be applied to all configurations you intend
to build separately. The eCos host tools as shipped by RedHat were
built using the "Win32 ANSI Release" Configuration. If you build the
"Win32 Release" Configuration, you will also need to have the Unicode
version of the MFC libraries and DLLs.)

5) Click "Build... (F7)". The compiled binaries will be located in the
Configtool folder on the V:\ drive.


NOTES:

1) When using WinCVS, make sure to use the default Windows mode to get
the tools. Using UNIX mode will break the Visual Studio project files
and you won't be able to open them. (It is preferable, in general, to
use Windows mode for all eCos files.)

2) There will be many warnings related to STL header compilation.
These are benign. There are also some warnings related to missing help
files at the beginning of the Configtool project compilation. These
can also be ignored.

3) To build the other Win32 projects in the host tools, it may be
necessary to repeat step 4.b) above. (Again, this depends on which
version of Tcl is in use.)
