Ok I have made some progress. After reading some of the other posts
about dlls/libs - i decided to add all the libs. i.e. Proj.
Properties->Linker->Input->Additional Dependancies
I am left with just 4 unresolved dependencies which I can't seem to get
rid of. Do I have to link to any other libraries other than what's in
the lib folder?
Maybe someone can point out which lib the following functions reside in
(looks to me like xpcom or one of its associated libs).
Linking...

Hi Niky,
Thanks for the response.
I am using the latest source from cvs - if I can't get it working I a
might try drop back to 1.5.
I don't have the option of using Single Thread.. all options are Multi.
It is interesting to note that if I change to MD it gives me a different
error - but I don't think this has anything to do with it.

Hi Niky,
Thanks for the instructions - has helped alot.
I am just at the point where I can nearly build my own test
application - but am getting some linking errors. It seems that it
cannot find the proper dll's (xpcom.dll etc.)
I followed your instructions and done the following -
- built mozilla
- setup my VS environment to include the appropriate headers. (Proj.
Properties->C/C++ -> General->Additional Include Directives
- added libraries to be linked to the app (Proj.
Properties->Linker->Input->Additional Dependancies)
- added \mozilla\dist\bin to my path
- Told linker to ignore LIBCD.lib/LIBC.lib (Proj.
Properties->Linker->Input->Ignore Specific Libraries)
In addition I have done the following to make my application compile -
- Added the preprocessor tag MOZILLA_INTERNAL_API (Proj.
Properties->C/C++ -> Preprocessor->Preprocessor Definitions)
- Changed runtime library to MT (Proj. Properties->C/C++ ->Code
Generation->Runtime Library)
- Changed buffer security check to no (Proj. Properties->C/C++ ->Code
Generation->Buffer Security Check)
- Change so it is not using precompiled headers (Proj.
Properties->C/C++ ->Precompiled Headers->Create/Use Precompiled Header)
- Told linker to ignore MSVCRT.lib (Proj.
Properties->Linker->Input->Ignore Specific Libraries)
Below is a snippet of the linking errors I am getting (I think
problem with linking to xpcom.dll) -
Linking...

build an embedded windows app.
My accomplishment :
- I managed to compile mozilla tree on windows.
But now, i am kinda stuck. What do i do next?
- I can build and run mfcembed.exe by using "make" from cygwin
- I cannot load mfcembed project files in VS 2005 (corrupt dsp file)
- How do i use visual studio 2005 to build an embedding app?
- What kind of project within VS2005? I am guessing either mfc
or CLR.
- Is it better to build a CLR windows forms app that embeds
mozilla or MFC?
Ravi,
Well, you have two ways to go about it really. You can use the
Mozilla Active X from John Lock...or you can implement the
interfaces yourself. The Active X control doesn't send back all the
events, so really its best for just displaying web pages...not
reacting to events like clicks and key presses (unless it's been
updated recently). I choose to implement the interfaces myself, it
takes a bit longer to get it setup, but you have more control over
it. Which one are you going to use? In either case...below are
some instructions that I've put together over the few times I've had
to setup my environment for embedding Gecko (Win 2K & VS 2003). I'm
not sure exactly how far along you are (I see you were able to make
from cygwin the mfcembed.exe) so I'll start from the beginning, hope
this helps!!
NOTE*** I've only tried this with the 1.0.7 code, not 1.5 yet.
--You've probably done all the way to step 12.
1) Download and unzip the mozilla source code
2) Download Cygwin (http://www.cygwin.com) and run...install the
following packages
a) 'make' under the 'Devel' category
b) 'perl' under 'Interpreters' category
c) 'unzip' under 'Archive' category
d) 'zip' under 'Archive' category
3) Download Netscape's wintools.zip from
http://ftp.mozilla.org/pub/mozilla.org/mozilla/source/wintools.zip
and put that in a 'Tools' directory...or some other name you want to
use. Unzip there.
a) Run the install.bat file under the "buildtools\windows"
directory
4) Next, go to
ftp://ftp.mozilla.org/pub/mozilla.org/mozilla/libraries/win32/ and
download the glib and libIDL version 7.1 (I THINK it's the same for
VS 2005) and extract to the same dir as you did your wintools.zip file
5) Now you have to setup your environment variables for the user
(right click on "My Computer" -> Properties, Advanced tab,
Environment Variables button)
GLIB = <where ever you unzipped glib>\vc71
LIBIDL = <where ever you unzipped libIDL>\vc71
MOZ_TOOLS = <where ever you unzipped wintools>\windows
PATH = %GLIB%\bin;%LIBIDL%\bin;%MOZ_TOOLS%\bin
HOME = <Where ever the base dir of your project resides> //This
is for CYGWIN so it knows what it's home directory is
//Optional
XPCOM_DEBUG_BREAK = warn
6) Create yourself a ".mozconfig" file...easiest way I've found to
do it is do a "copy con" command in the cmd window just to create
the file...once created, open with notepad and edit. Windows
doesn't like to create names that start with a period in the explorer.
7) Mozilla.org has some good tools on creating a .mozconfig
file...here is the one I use to make a browser...very simple
#-----------------------------------------------------------------
# For building firefox, this needs to be included
.. $topsrcdir/browser/config/mozconfig
# Options for client.mk.
mk_add_options MOZ_CO_PROJECT=browser
# Options for 'configure' (same as command-line options).
ac_add_options --enable-application=browser
ac_add_options --enable-crypto
#-----------------------------------------------------------------
8) Make a shortcut to vsvars32.bat created by the VS.Net app, this
will setup some things for building
9) Rename the link.exe in your Cygwin/bin to something else...like
link.exe.old
10) run the vsvars32.bat, browse to where you installed Cygwin and
run the Cygwin.bat file.
11) Once it's up and running, navigate to the mozilla dir (where you
unzipped the mozilla code) and run "./configure"
12) Once that is done, run "make -f client.mk build" to start the
building process.
Now to setup the VS environment to build...I use straight Win32, so
I create a blank project when I start this.
After you have your blank project setup, do the following:
Directories the project needs to know where to search for include
files:
\mozilla\dist\include\layout
\mozilla\dist\include\dom
\mozilla\dist\include\uriloader
\mozilla\dist\include\profdirserviceprovider
\mozilla\dist\include\string
\mozilla\dist\include\necko
\mozilla\dist\include\gfx
\mozilla\dist\include\docshell
\mozilla\dist\include\widget
\mozilla\dist\include\webbrwsr
\mozilla\dist\include\windowwatcher
\mozilla\dist\include\embed_base
\mozilla\dist\include\nspr
\mozilla\dist\include\xpcom
These libraries also need to be linked to your app
xpcom.lib
embed_base_s.lib
nspr4.lib
profdirserviceprovider_s.lib
Also add \mozilla\dist\lib to the list of directories it looks in
for libraries for the project
Also add \mozilla\dist\bin to your PATH environment variable so it
will know where to find xpcom.dll, etc...
Tell the linker to ignore LIBCD.lib (Debug mode)/LIBC.lib (Release
mode)
Whew...okay, I think thats it. My notes are a little old so they
may be a little quirky but that is the basic steps of what I do to
get my environment setup for embedding gecko. Good Luck!!
