As outlined in [1], the build-infra project would like to push the
current work into jdk8 in order to expose it to a wider audience.
The webrevs are made against the jdk8/build forest. In each
repository, there are two kinds of changes: <br>
<br>
1. Changes to old makefiles and source code to be compatible with
the new build.<br>
2. The new makefiles<br>
<br>
For corba, jaxp and jaxws, all changes of category 1 have already
gone in. For langtools, we are awaiting one more change for
introducing the GenerateNativeHeader annotation. For hotspot, all
necessary changes have been pushed into hotspot-rt. For jdk, there
are two webrevs, one with everything and one with just the category
1 changes, to make it easier to see them. Finally for the root
repository there are only new files in the common subdir.<br>
<br>
root, configure script and makefiles:<br>

<br>
langtools, 1 new makefile:<br>
<a moz-do-not-send="true"

<br>
langtools, GenerateNativeHeader annotation (this is already going in
through tools, but adding it here for reference as the jdk changes
depend on it)<br>
<a moz-do-not-send="true"
href="http://cr.openjdk.java.net/%7Eerikj/build-infra-m1/webrev-langtools-nativeheader/">http://cr.openjdk.java.net/~erikj/build-infra-m1/webrev-langtools-nativeheader/</a><br>
<br>
corba, 1 new makefile:<br>
<a moz-do-not-send="true"
href="http://cr.openjdk.java.net/%7Eerikj/build-infra-m1/webrev-corba-new/">http://cr.openjdk.java.net/~erikj/build-infra-m1/webrev-corba-new/</a><br>
<br>
jaxp, 1 new makefile<br>
<a moz-do-not-send="true"
href="http://cr.openjdk.java.net/%7Eerikj/build-infra-m1/webrev-jaxp-new/">http://cr.openjdk.java.net/~erikj/build-infra-m1/webrev-jaxp-new/</a><br>
<br>
jaxws, 1 new makefile<br>
<a moz-do-not-send="true"
href="http://cr.openjdk.java.net/%7Eerikj/build-infra-m1/webrev-jaxws-new/">http://cr.openjdk.java.net/~erikj/build-infra-m1/webrev-jaxws-new/</a><br>
<br>
jdk, just the changes to old files<br>
<a moz-do-not-send="true"
href="http://cr.openjdk.java.net/%7Eerikj/build-infra-m1/webrev-jdk-other/">http://cr.openjdk.java.net/~erikj/build-infra-m1/webrev-jdk-other/</a><br>
<br>
jdk, all changes including a partial copy of the old makefiles.<br>
<a moz-do-not-send="true"
href="http://cr.openjdk.java.net/%7Eerikj/build-infra-m1/webrev-jdk-new/">http://cr.openjdk.java.net/~erikj/build-infra-m1/webrev-jdk-new/</a><br>
<br>
Of course, if you prefer you can look at the new makefiles directly
in the build-infra/jdk8 repository forest too.<br>
<br>
These changes should not affect the old build at all. To build using
the new build system, change directory to "common/makefiles" and:<br>
<br>
../autoconf/configure<br>
make<br>
(make images)<br>
<br>
State of the new build (the old build should of course be
unaffected):<br>
<ul>
<li>Linux 32bit: Works<br>
</li>
<li>Linux 64bit: Works</li>
<li>Windows 32bit: Works<br>
</li>
<li>Windows 64bit: Works</li>
<li>Solaris i586: Builds but launchers currently unusable</li>
</ul>
Some notes:<br>
<ul>
<li>The old and new build (on linux x64) produce very close to
equal results. There is a comparison script in
common/bin/compareimage.sh with which this can be checked.</li>
<li>Not all makefiles in jdk have been converted yet, for those
that haven't been, a copy of the old files are used.</li>
<li>Not all promised features in the java compilation are active
and ready in this milestone. Most notably, it's still not using
more than one cpu and the nifty new dependency tracking is
disabled. A clean build is still pretty fast, but incremental
builds aren't as good as they will be yet.</li>
<li>On windows, only cygwin is currently supported. <br>
</li>
</ul>
Now please share your feedback!<br>
