Overview

The aim of this project is to enhance Vision with a support for multiple screens.

Eiffel Studio

• I'll give you here a step for step instruction at how I got a vision2 project to work under windows

Download

• build 59623 from cur Eiffel builds old Eiffel builds
• If you don't already have it installed:

MS Platform SDK Microsoft .NET Framework Version 2.0 Redistributable Package (x86) .NET 2.0 SDK for x86

• cygwin with bash

How I chose the Directories (just change everywhere I use them adequatly) =

• C:\Eiffel57\ - Eiffel instal directory
• C:\Eiffel57\soft-arch\ - svn checkout
• C:\Program Files\Microsoft.NET\ - Microsoft.NET Framework
• C:\Program Files\Microsoft Platform SDK\ - Microsoft Platform SDK
• C:\cygwin\ - Cygwin Installation

needed SVN checkout

• https://eiffelsoftware.origo.ethz.ch/svn/es/branches/soft-arch/Src into C:\Eiffel57\soft-arch\
• https://eiffelsoftware.origo.ethz.ch/svn/es/branches/soft-arch/Delivery into C:\Eiffel57\soft-arch\Delivery
• https://eiffelsoftware.origo.ethz.ch/svn/es/branches/soft-arch/free_add_ons into C:\Eiffel57\soft-arch\free_add_ons

set Environment Variables

set PATH=C:\Programme\Microsoft.NET\SDK\v2.0\Bin;C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727;C:\Programme\Microsoft Platform SDK\bin;C:\Programme\Microsoft Visual Studio 8\VC\bin;C:\Programme\Microsoft Visual Studio 8\Common7\IDE;C:\Programme\Microsoft Visual Studio 8\VC\vcpackages;C:\Programme\Microsoft Platform SDK\Bin;C:\Programme\Microsoft Visual Studio 8\VC\bin;%PATH%;C:\cygwin\bin

set INCLUDE=C:\Programme\Microsoft.NET\SDK\v2.0\include;C:\Programme\Microsoft Platform SDK\Include;C:\Programme\Microsoft Platform SDK\Include\crt;C:\Programme\Microsoft Platform SDK\Include\crt\sys;C:\Programme\Microsoft Platform SDK\Include\mfc;C:\Programme\Microsoft Platform SDK\Include\atl;C:\Programme\Microsoft Visual Studio 8\VC\include

set LIB=C:\Programme\Microsoft.NET\SDK\v2.0\Lib;C:\Programme\Microsoft Platform SDK\Lib;C:\Programme\Microsoft Visual Studio 8\VC\lib;

set ISE_EIFFEL=C:\Eiffel57\

These last Variables I'm not sure are needed...

set EIFFEL_SRC=C:\Eiffel57\soft-arch\

set ISE_PLATFORM=windows

set ISE_C_COMPILER=msc

Install needed Applications (see also directories above)

• install MS Platform SDK, MS .NET Framework, .NET SDK
• install cygwin
• install Eiffel build

Install Gobo

DOS

cd %EIFFEL_SRC%\library
tar xvfz %EIFFEL_SRC%\free_add_ons\gobo\gobo_34_win.tgz

Bash

cd $EIFFEL_SRC/library
tar xvzf $EIFFEL_SRC/free_add_ons/gobo/gobo_34_win.tgz

Compile Libraries

• Preparation:

rename C:\Eiffel57\soft-arch\C\CONFIGS\windows-msc-x86 to 'windows-msc-x86 old' download windows-msc-x86-2005.obj into C:\Eiffel57\soft-arch\C\CONFIGS\ and rename it to windows-msc-x86

• Compilation:
  • Compiling run-time

DOS

cd %EIFFEL_SRC%/C
configure win32 m

Bash

cd $EIFFEL_SRC/C
./configure.bat win32 m

If you are using a 64Bit Machine change the win32 to win64

On Windows 32 bits to clean up all the generated files you do: DOS

configure clean

Bash

./configure.bat clean

• • Compiling C code from libraries

DOS

cd %EIFFEL_SRC%/library/net/Clib
make_msc.bat
cd %EIFFEL_SRC%/library/vision2/Clib
make_msc.bat
cd %EIFFEL_SRC%/library/wel/Clib
make_msc.bat

Bash

cd $EIFFEL_SRC/library/net/Clib
./make_msc.bat
cd $EIFFEL_SRC/library/vision2/Clib
./make_msc.bat
cd $EIFFEL_SRC/library/wel/Clib
./make_msc.bat

• • Compiling C code from C_library

DOS

cd %EIFFEL_SRC%/C_library/zlib
make_msc.bat
cd %EIFFEL_SRC%/C_library/libpng
make_msc.bat

Bash

cd $EIFFEL_SRC/C_library/zlib
./make_msc.bat
cd $EIFFEL_SRC/C_library/libpng
./make_msc.bat

• • Compiling C code from compiler

DOS

cd %EIFFEL_SRC%/Eiffel/library/cli_writer/Clib
nmake

Bash

cd $EIFFEL_SRC/Eiffel/library/cli_writer/Clib
nmake

Start Eiffel Studio

You should be able now to create a vision2 project and compile it !!!

Resources

• In order to be able to change the library code you have to delete the 'readonly="True"' in the library tags of the project's acex file

• C# screen class interface

• Gdk - Resources:
  • class GdkDisplay
  • class GdkScreen

• WEL - Resources:
  • NONE

• Win32 API - Resources:
  • look at the platform SDK under 'Win32 API'
  • Wel uses a loopback function to get access to all fonts (it's pretty much the same that we have to do)
    • in the SDK you find the EnumFontFamilies function under 'Graphics Device Interface' -> 'Fonts and Text' -> '... Reference' -> '... Functions'
    • look at %Eiffel%\library\wel\clib\enumfold.c
    • look at class wel_font_family_enumerator - especially at feature cwin_enum_font_families

• Team SVN Rep: You need to backup and remove the directories 'vison2' and 'wel' in your '/Eiffel57/library/' directory and run a svn checkout from https://eiffelsoftware.origo.ethz.ch/svn/es/branches/soft-arch/TeamMultiScreenSupport .

Implementation

class EV_SCREEN:

• allscreenslist [EV_MULTISCREEN]
• primaryscreen : EV_MULTISCREEN

class EV_MULTISCREEN (inherits EV_SCREEN):

• create class
• redefine inherited features for mutliscreen as needed

class EV_SCREEN_IMP (inherits EV_SCREEN_I):

• add multiscreen features as needed

class EV_SCREEN_I:

• add new deferred features from EV_SCREEN_IMP

class GDK_EXTERNALS:

• add multiscreen features as needed

Milestones

M1: June 1st

• needed gdk features
• decide upon implementation

M2: May ???

• To be completed by the team

To do

• Fabio:
  • find needed WEL features (and underlying routines - WIN32 API)
  • create svn-dir (done. see resources)
  • look at Win32API and get dummy prog to work (see resources)

• Pascal:
  • look at Win32API and get dummy prog to work (see resources)

• Pawi
  • find out how to do the docu

• Dario
  • find out how works 'external' (done. works under linux)
  • create Class EV_MULTISCREEN (inherits EV_SCREEN)
  • look at Win32API and get dummy prog to work (see resources)
