How to build Firefox on Windows 64-bit machine with Visual Studio 2010

I thought you might want to know what are the instructions how to generate a Windows 64-bit build of Firefox with VS2010.

Setup instructions

1. Install Visual Studio 2010 Pro (4/12/2010, vs_proweb.exe)
2. Install Windows 7 SDK (winsdk_web.exe - v7 - 7/24/2009 )  
3. Install MozillaBuild 1.4
4. Download into your Mozilla Build installation directory (e.g. C:\mozilla-build) the following files:
• start-msvc10-x64.bat 
• guess-msvc.bat (you will have to replace current one)
5. Rename or delete this file:
• 
  
  

  C:\mozilla-build\vim\vim72\install.exe

NOTE: At the time of posting MozillaBuild 1.5 has not yet been released. Steps 4 and 5 should not apply with the new version.

 Now let's build

• Start Mozilla Build with start-msvc10-x64.bat
• Use for instance this mozconfig 

. $topsrcdir/browser/config/mozconfig

ac_add_options --target=x86_64-pc-mingw32
ac_add_options --host=x86_64-pc-mingw32 

# Once we fix jemalloc for VC10 + x64 - bug 569375
export WIN32_REDIST_DIR="C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\redist\x64\Microsoft.VC100.CRT"

•  and then:

make -f client.mk build

NOTE: The WIN32_REDIST_DIR is because we don't have jemalloc support for VS2010; we do have support for it in VS2008 and VS2005 (therefore you won't need the WIN32_REDIST_DIR line). For VS2005 use start-msvc8-x64.bat and for VS2008 use start-msvc9-x64.bat (NOTE I have not tested it myself).

I hope this helps you out,
Armen

EDIT: I had to switch VS2005 and VS2008 in the last note of this post. I had them switched. Thanks Makoto!
