I'm trying it on my Linux x64 now. The first feeling is that my computer
is slowed down a lot more than the old build. The 4 CPUs all show a near
100% usage (it's building hotspot now). The guide says I can adjust it
with --with-num-cores, but it's only available for configure time and
not make, right?
Also, the build output directory name is
build/linux-x64-normal-server-release/, the executables are in
build/linux-x64-normal-server-release/jdk/bin, and images in
build/linux-x64-normal-server-release/images/j2sdk-image. All my
existing scripts need to be modified.
Thanks

The build-infra project [1] has been working for a while with creating a new

improved build performance and improved ease of use.
The first part of this project has now been pushed to the jdk8 master forest.
This means that the new build system is available for you to try out! The old
build system is still there, and if you want to continue to use it, you will
notice no difference (for now...).
But if you are interested in trying the new build system, we welcome you to
experiment with it! The basic operation is:
cd common/makefiles
../autoconf/configure
FYI...
I had to adjust this to:
chmod a+x ../bin/*
bash ../autoconf/configure
The OpenJDK repositories do not allow any files with execute permissions.
-kto
make
More information is available in the new build README [2]. If you want to try
the new build system, please read it first.
Please note that the new build system is not yet complete. We do not yet have
full platform support, nor are all parts of the old build converted (but then
we fall back on the old build system), and there are likely to be bugs. Most of
all, we need to have exposure on a wide range of different build systems, since
the reality is always so much messier than you'd want to believe. :-) Please
help us to resolve such issues early by trying the new build system!
Any questions or discussions on the new build system should be sent to
[email protected].
