        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.)
