enabling javascript
cyril giraudon
I've succeeded in embedding gecko 1.9 in a wxWidget window.
It is a very simple beginning.
However, when the "http;//developer.mozilla.org" is loaded, I can see
the noscript element :
<div id="noscript"><p>Some features of this site require JavaScript.</
p></div>.
That is to say, javascript is disabled. When I click on hyperlink, the
application crashes.
What is to be done to enable javascript ?
Is it necessary to handle a profile like the ".vendor / app /
profile.file " created by xulrunner ?
Thanks a lot,
Cyril.

You can perhaps look into this, which I got to work.

Thanks a lot Martin,
I try to compile minimal with the following commands :
> ls
> unzip minimal.zip
> ls
minimal minimal.zip
> mkdir build
> cd build
> cmake -version
cmake version 2.4-patch 3
> cmake ../minimal -DCBS_BUILD=1
I obtain the error :
"""

Can Minimal be compiled or is it an example to be read ?
What is the cmake version you use, BULD_EXECUTABLE is recognized with
2.4-patch 3 ?
I use a mandriva 2007 linux box.
Thanks,
Cyril.

makefile.
Minimal works fine, three little issues :
- gecko dimensions are initially very little and gecko is localized
in the left upper corner (it is ok after the first OnSize event);
- When I exit the application, there's a segmentation fault.
- When the about window is shown, gecko disappears in the left right
corner.
I will look at that.
Thanks again.
Cyril.
