Hi,
I'm trying to build an application embeding Gecko.
I am following the information obtained from
http://www.mozilla.org/projects/embedding/
but I am finding myself a little lost.
This is a run down of what I have attempted so far, feel free to point
out anything that
is wrong or just plain stupid.
(I apologise in advance for the interleaving of explanations and output
messages)
I downloaded the mozilla source tree from:
ftp://ftp.mozilla.org/pub/mozilla.org/mozilla/releases/mozilla1.7.13/source/mozilla-1.7.13-source.tar.bz2
<ftp://ftp.mozilla.org/pub/mozilla.org/mozilla/releases/mozilla1.7.13/source/mozilla-1.7.13-source.tar.bz2>
I then created a .mozconfig file in ~/Desktop/mozilla/ containing:
ac_add_options --enable-default-toolkit=gtk2
I then proceeded to build the source by:
make -f client.mk <http://client.mk> build
An hour and a half later the build finished without any apparent errors.
I then proceeded as follows to make an embedding build:
cd ~/Desktop/mozilla/embedding/config
make
Lots of output scrolls by, some of which as follows might be of interest:
cp: cannot stat `./all.js': No such file or directory

I then proceeded to try and run TestGtkEmbed
$ cd ~/Desktop/mozilla/dist/Embed/
$ ./run-mozilla.sh ./TestGtkEmbed

Looking in EmbedPrivate.cpp on line 264 we have:
// get the native drawing area
GdkWindow *tmp_window =

And thats where i am now. Any information on what i have done wrong,
what i need to do, or further links to resources about embeding Gecko
into applications would be appreciated.
Thanks,
Lance Fitz-Herbert.
