A few noteworthy details about Gingerbread in AOSP:
-Gingerbread requires a 64-bit JDK 1.6 (which implies that you need a 64-bit host to build it). The instructions at source.android.com are outdated, and 64-bit Ubuntu 10.4 is the preferred environment. We'll be updating those instructions in the coming weeks.
-You should expect that Gingerbread will use at least 12GB of disk space after syncing and building. The number will be higher if you build for multiple hardware targets.
-Android likes to be built on machines with lots of RAM. There are benefits up to at least 12GB of RAM (and more if you routinely work in multiple branches simultaneously).
-The toolchain in android-2.3_r1 is known to work well for ARMv7 targets, but it sometimes generates incorrect ARMv5 code. The toolchain in the gingerbread branch contains a fix for the ARMv5 code generation, but hasn't been tested nearly as much.

Thanks JBQ. This makes it easy to switch completely to 10.6 post-Gingerbread.
On the same note, Would 32-bit Ubuntu host be un-supported on Gingerbread? Wondering what would be your recommendation to handle two builds (post/pre Gingerbread) on the same linux machine. thanks, -Jey

You can build froyo and gingerbread on the same linux host by having Sun JDK 1.5 installed and default, and Sun JDK 1.6 installed (but not default).
In that case, the envsetup.sh from gingerbread will switch to the 1.6 JDK. Caveat: once you do that in a terminal, you won't be able to use the same terminal for froyo any more.

I am hoping the lower layer pieces from external vendors can work this way too. There are issues (probably non-AOSP code) that I see on 32-bit Linux that I will have to figure out.

I've downloaded and built the gingerbread source (thanks!). I executed the resulting system.img on the emulator and it works.
Now I'm trying to set up my Eclipse environment. I decided to take a walk on the wild side and use Eclipse version "Helios" (3.6.1-linux-gtk-x86_64) configured to use JRE java-6-sun-1.6.0.22.
5. Select "Create project from existing source", enter the path...
There is no "Create project from existing source" option in Helios. I found some instructions on the net that said:
uncheck the "Use default location" box. browse to the location where you extracted the source # I assumed this is the directory where I copied the .classpath file
I hit "Finish" and the wizard and Eclipse just sat there a long time and then correctly populated my workspace.
But there was a red exclamation point next to my project in the package explorer and in the Problems window there are 3 errors:
project 'ginger' is missing required library: 'out/target/common/obj/JAVA_LIBRARIES/google-common-intermediates/javalib.j a r project 'ginger' is missing required library: 'out/target/common/obj/JAVA_LIBRARIES/gsf-client-intermediates/javalib.jar The project cannot be built until build path errors are resolved.
I having an issue with prelinking in gingerbread. Apriori compiles
with warnings http://pastebin.com/0zpqJLgw and only 3 modules listed
in prelink map actually end up prelinked. The rest are picked up as
not prelinked and were verified with isprelinked. Any ideas I've never
had this issue with froyo or before and just switched to x64 distro to
build gingerbread.

I have successfully built froyo with full_passion as target on my new 64bit ubuntu 10.04 host (AMD 6-core CPU, much faster than my previous 32bit host).
I only installed JDK 1.6. The only tricky point is to comment line 104-132 in build/core/main.mk which is used to check java version.

You need to be aware of two things when building froyo with JDK 1.6:
-This hasn't been tested by Google. While unlikely, there's a possibility that subtle differences in the toolchain could creep up as bugs.
-If you're sharing your source tree with other people, you need to be very careful to not use @Override on interface methods, as JDK 1.5 doesn't support that.
