Scott Mozilla Build
Alright, so after a lot of fighting with Windows Vista I finally caved in and built Mozilla on Windows XP instead. Firefox built and ran on the first try on XP. The problem I had with Vista wasn't the build of Firefox itself. The start batch files from Mozilla Build simply refused to work. I had to do a lot of registry editing to enter the keys it was looking for (the path to my Visual Studio was not in the registry where Mozilla Build was looking). Eventually I hit a wall:
"Unexpected \Microsoft"
Great... no idea how to fix that.
I'll fight with Vista later. Here's my build from XP using the following mozconfig:
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/obj-firefox
mk_add_options MOZ_CO_PROJECT=browser
ac_add_options --enable-application=browser
ac_add_options --disable-optimize
ac_add_options --enable-debug
ac_add_options --disable-tests
ac_add_options --disable-vista-sdk-requirements
