=== Install needed Applications (see also directories above) ===
* install MS Platform SDK, MS .NET Framework, .NET SDK
* install cygwin
* install Eiffel build
 
=== Install Gobo ===
'''DOS'''
<pre>cd %EIFFEL_SRC%\library
tar xvfz %EIFFEL_SRC%\free_add_ons\gobo\gobo_34_win.tgz
</pre>
 
'''Bash'''
<pre>cd $EIFFEL_SRC/library
tar xvzf $EIFFEL_SRC/free_add_ons/gobo/gobo_34_win.tgz
</pre>
 
=== Compile Libraries ===
* Preparation:
rename C:\Eiffel57\soft-arch\C\CONFIGS\windows-msc-x86 to 'windows-msc-x86 old'
download [http://origo.ethz.ch/pipermail/es-devel/attachments/20060424/e5afb9a9/windows-msc-x86-2005.obj windows-msc-x86-2005.obj] into C:\Eiffel57\soft-arch\C\CONFIGS\ and rename it to windows-msc-x86
 
* Compilation:
** Compiling run-time
 
'''DOS'''
<pre>cd %EIFFEL_SRC%/C
configure win32 m</pre>
 
'''Bash'''
<pre>cd $EIFFEL_SRC/C
./configure.bat win32 m</pre>
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'''
<pre>configure clean</pre>
'''Bash'''
<pre>./configure.bat clean</pre>
 
** Compiling C code from libraries
'''DOS'''
<pre>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</pre>
'''Bash'''
<pre>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</pre>
 
** Compiling C code from C_library
'''DOS'''
<pre>cd %EIFFEL_SRC%/C_library/zlib
make_msc.bat
cd %EIFFEL_SRC%/C_library/libpng
make_msc.bat</pre>
'''Bash'''
<pre>cd $EIFFEL_SRC/C_library/zlib
./make_msc.bat
cd $EIFFEL_SRC/C_library/libpng
./make_msc.bat</pre>
 
 
** Compiling C code from compiler
'''DOS'''
<pre>cd %EIFFEL_SRC%/Eiffel/library/cli_writer/Clib
nmake</pre>
'''Bash'''
<pre>cd $EIFFEL_SRC/Eiffel/library/cli_writer/Clib
nmake</pre>
 
 
=== Start Eiffel Studio ===

Revision as of 17:23, 16 June 2006


Overview

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

Eiffel Studio

Step by Step build installation

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


  • 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


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 (take a look at Doc builder)


  • 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)
