[erlang-patches] Re: Fixes for building erlang under windows

[Davide Marquês]

Hi Mazen,
Simply going through the steps in README.win32 doesn't seem to be enough for
configure to pick up the wxWidgets installation/libraries.

These were the steps I took:
- run the wxWidgets-2.8.10 installer;
- edit <wxWidgets dir>/include/wx/msw/setup.h and enable:
- wxUSE_GLCANVAS
- wxUSE_POSTSCRIPT
- wxUSE_GRAPHICS_CONTEXT
- open <wxWidgets dir>/build/msw/wx.dsw (letting VC convert the projects)
- build the "Unicode Release" and "Unicode Debug" configurations
- open <wxWidgets dir>/contrib/build/stc/stc.dsw (letting VC convert the
projects)
- build the "Unicode Release" and "Unicode Debug" configurations
After which the C:\Program Files\wxWidgets-2.8.10\lib\vc_lib folder contais
195MB of .lib goodness (wxbase28d.lib, wxbase28u.lib, wxbase28d_net.lib,
wxbase28u_net.lib, ...).

This is the relevant part of the configure output:

The wx-config didn't exist at this point. As there was a wx-config.in file I
ran configure to create it. But that didn't help much.

Here are some of its outputs:

VC2008: wxWidgets-2.8.10 $ ./wx-config --libs-L/c/Progra~1/wxWidgets-2.8.10/lib
  -lwx_msw_richtext-2.8 -lwx_msw_aui-2.8 -lwx_msw_xrc-2.8 -lwx_msw_qa-2.8
-lwx_msw_html-2.8 -lwx_msw_adv-2.8 -lwx_msw_core-2.8 -lwx_base_xml-2.8
-lwx_base_net-2.8 -lwx_base-2.8

VC2008: wxWidgets-2.8.10 $ ./wx-config --static --libs

  Warning: No config found to match: ./wx-config --static --libs

  library build.  If this is part of an automated configuration
  test and no other errors occur, you may safely ignore it.
  You may use wx-config --list to see all configs available in
  the default prefix.


VC2008: wx $ wx-config --unicode --debug=yes  Warning: No config found to
match: /c/Progra~1/wxWidgets-2.8.10/wx-config --unicode --debug=yes
           in /c/Progra~1/wxWidgets-2.8.10/lib/wx/config

  library build.  If this is part of an automated configuration

The configure fails after this last check:

I'm obviously clueless. Any tips? :)
