Re: [Ekiga-devel-list] Cross-compiling ekiga for win32

[Michael Rickmann <mrickma gwdg de>]

Yes things have changed a week ago with "Split ekiga into an exec and
helper libs". This has been done to make the Win32 version Ekiga-plugin
capable, eventually.

Could you test whether attached diff also works for you it is similar to
yours with respect to the _win32_sysconfdir and fixes the ekiga-rc.o
trouble right from the beginning.

That Window is absolutely harmless. It is caused by some code in Opal
when debug output is selected and should only contain messages from the
h264_video_pwplugin_helper.exe. Ekiga's debug output should be contained
in a file ekiga-stderr.txt which should appear on your desktop. This
change of file location has become necessary because of security
features of newer Windows versions. I start Ekiga in debug mode from an
extra shortcut symbol with -d 4 added to the command line.
