[webkit-dev] VS2010 compilation

[forumer at smartmobili.com]

Hi,

I am trying to compile webkit on the following platform
Windows 7 Pro x64
Intel i5 2500K - 3.3 GHz
Microsoft Visual Studio 2010 Ultimate -ENU Version 10.0.30319
Microsoft Visual Studio 2010 Service Pack 1 Version 10.0.40219
Microsoft Visual Studio 2010 SDK SP1 Version 10.0.40219
Cygwin 1.7.15-1 installed in C:\Developer\cygwin

using VS2010 Ultimate with SP1 on a windows platform (Windows 7 x64 - 
Intel i5 2500K - 3.3 GHz) folllowing this blog :
http://blog.ashodnakashian.com/2012/01/building-webkit-on-windows-7-with-vs2010/
but unfortunately it nevers succeeds.
I would be curious to know if you are using cygwin 1.5 or 1.7 and what 
version of gcc?
For people interested here is my personal investigations about how to 
progress on this subject :


0) Check you don't have any visual open and zombie process MSBuild.exe

1) Install cygwin 1.7 with the following packages (perl, python, make, 
curl, unzip).(Personaly I like to install it inside c:\Developer\cygwin)
    We need an additional perl dependency Http/Datep.pm so let's install 
it too:

    $ perl -MCPAN -e shell
    $ install 'Http::Date'


2) Edit /etc/profile and comment the 3 lines like this
ORIGINAL_TMP=$TMP
ORIGINAL_TEMP=$TEMP
#unset TMP TEMP
tmp=$(cygpath -w "$ORIGINAL_TMP" 2> /dev/null)
temp=$(cygpath -w "$ORIGINAL_TEMP" 2> /dev/null)
#TMP="/tmp"
#TEMP="/tmp"

3) Launch cygwin and enter the following commands (I have modified 
original script from ashodnakashian to allow
    more configurations ie check if cygwin is installed or not in the 
default path, ...)

$ mkdir tmp && cd tmp
$ curl -k 
http://builds.nightly.webkit.org/files/trunk/src/WebKit-r123220.tar.bz2 
 > WebKit-r123220.tar.bz2
$ curl -k  http://www.smartmobili.com/downloads/WebKit-vs201x-Patch.zip 
 > WebKit-vs201x-Patch.zip
$ tar xvf WebKit-r123220.tar.bz2
$ mv WebKit-r123220/Tools/Scripts/pdevenv 
WebKit-r123220/Tools/Scripts/ORG_pdevenv
$ unzip -d WebKit-r123220 WebKit-vs201x-Patch.zip


Ok so now we are ready to launch the compilation, go to Start 
Menu\Microsoft Visual Studio 2010\Visual Studio Tools
and right-click on Visual Studio Command Prompt (2010) and click on Run 
as Administrator

>cd C:\Developer\cygwin\home\Vincent\WebKit-r123220
>vs201x-build-env.cmd

If everything goes well you should see something like :

Setting up Cygwin directory...
Note: Using custom cygwin path
Lien symbolique créé pour C:\cygwin <<===>> C:\Developer\cygwin
Setting up WebKit directory...
Exporting environment varibles...
Note: Remember to set devenv.exe to run as administrator!
Running Cygwin...

and now you are in cygwin.

$ build-webkit --wincairo 2>&1 | tee build.txt

And now I am a bit stuck with this error :

already been added. Key in dictionary: 'TMP'  Key being added: 'tmp'
3>------ Build started: Project: JavaScriptCoreGenerated,

The first error is weird because when I have a look at 
Source\WTF\WTF.vcproj\copy-files.cmd I can see the following line 
starting by #

# FIXME: Why is WTF copying over create_hash_table?

The second error is about cl and duplicated key and I know it has 
something to do with cygwin way of declaring tmp and TMP and I thought
my modification would fix it but it seems it's not the case
Like suggested on the original blog I have also renamed 
Tools\vcbin\cl.exe and midl.exe to use the ones from Visual Studio, 
could it explain this problem ?


Any help would be appreciated.

Thanks
