Prepare fat universal OpenJDK libraries
<ul>
<li>Open a terminal in your home folder, e.g. <i>/Users/jogamp</i></li>
<li>The OpenJDK library folder of each target platform, x86_64 or aarch64, is <i>/Library/Java/JavaVirtualMachines/temurin-17.jdk/Contents/Home/lib</i></li>
<li>Transfer the x86_64 OpenJDK library folder to <i>temurin-17.jdk.amd64.lib</i><li>
<li>Transfer the aarch64 OpenJDK library folder to <i> temurin-17.jdk.arm64.lib</i></li>
<li>Run the script <i>gluegen/make/scripts/make.macosx.jdk_lipo_libs.sh</i></li>
<li>Fat universal OpenJDK libraries are produced into <i>temurin-17.jdk.fat.lib</i></li>
</ul>
Now we have to tell the <i>gluegen</i> build framework to use <i>temurin-17.jdk.fat.lib</i>,
by adding an <i>ant</i> macro in <i>$HOME/gluegen.properties</i>
<pre>
java.lib.dir.platform=/Users/jogamp/temurin-17.jdk.fat.lib
</pre>
Replace <i>jogamp</i> with your user name.

<h2>Build Steps</h2>
<hr/>
<p>
Here are the steps that are required in order to build GlueGen.
</p>
<ol>
<li><b>Optain the source code</b> using git:
<ul>
<li><a href="http://jogamp.org/git/?p=gluegen.git">Gluegen Dev GIT Repo</a></li>
</ul><br/>
It is crucial that you checkout the source code under a common root directory:
<pre>
/home/dude/projects/jogamp> git clone --recurse-submodules git://jogamp.org/srv/scm/gluegen.git gluegen
</pre>
Now you should have following directory structure:
<pre>
/home/dude/projects/jogamp
/home/dude/projects/jogamp/gluegen
</pre>
<p>
Note-1: The GlueGen source must be fetched using <i>-recurse-submodules</i>,
which imports <i>JCPP</i>, now used as the default C preprocessor.
</p>
</li>
<li> <b>Unset your CLASSPATH environment variable:</b> <br/>
The Ant build requires that the GlueGen jars not be visible on the classpath. On Unix, type
<code> unsetenv CLASSPATH </code> into a csh or tcsh shell, or <code> unset CLASSPATH </code>
into a Bourne shell. On Windows, type <code> set CLASSPATH= </code> into a command prompt.
</li>
<li> <b>Optional</b> <i>Copy and edit <b>gluegen.properties</b>:</i> <br/>
To specify different basic options for components and compilers,<br/>
copy <b>gluegen/make/gluegen.properties</b> into your home directory (pointed to by the Java system property <b>user.home</b>). <br/></li>
<li> <b>Build the source tree:</b> <br/>
Open a command shell in the "gluegen/make" directory of the source tree and invoke <code>ant</code>
with the given properties as follows
<pre>
cd /home/dude/projects/jogamp/gluegen/make/
ant
</pre>
Optionally you can also set certain build features via properites or environment variables
<pre>
Feature Property or Environment Variable
developer-zip-archive: build.archiveon=true BUILD_ARCHIVE=true
Native Debug Code: c.compiler.debug=true
Java Debug Code: javacdebuglevel="source,lines,vars"
</pre>
</li>
<li> <b>Test your build:</b> <br/> Stay in your command shell in the "gluegen/make" directory of the source tree and invoke <code>ant</code> with above properties or environment variables and use the target <code>junit.run</code>.</li>
<li> <b>Build Javadoc:</b> <br/> Stay in your command shell in the "gluegen/make" directory of the source tree and invoke <code>ant</code> with above properties or environment variables and use the target <code>doxygen.public</code> or <code>doxygen.all</code>.
This will produce the end-user documentation for GlueGen along with some auxiliary utility packages.
</li>
</ol>
Note that there might be a few warnings produced by ANTLR about the
C grammar and our modifications to some of the signatures of the
productions; the C grammar warnings have been documented by the
author of the grammar as having been investigated completely and
harmless, and the warnings about our modifications are also
harmless.
<h2> Common build problems </h2>
<ol>
<li>
<b>Your CLASSPATH environment variable appears to be set (some GlueGen classes are currently visible to the build.)</b>, and $CLASSPATH isn't set.
An older version of GlueGen was installed into the extension directory of the JDK you're using to build the
current GlueGen. On Windows and Linux, delete any ANTLR jars from jre/lib/ext, and on Mac OS X, delete them from
/Library/Java/Extensions. It is generally not a good idea to drop GlueGen directly into the extensions directory,
as this can interfere with upgrades via Java Web Start.
</li>
<li>
<b>CharScanner; panic: ClassNotFoundException: com.jogamp.gluegen.cgram.CToken</b>
This occurs because ANTLR was dropped into the Extensions
directory of the JRE/JDK. On Windows and Linux, delete any ANTLR jars from jre/lib/ext,
and on Mac OS X, delete them from /Library/Java/Extensions. Use the antlr.jar property in the build.xml
to point to a JRE-external location of this jar file.
</li>
</ol>
