<title>Installation of <application>J2SDK</application></title>

<para>Both versions will be installed in parallel. You may choose to keep 
either or both.</para>

<para>Installation of the precompiled <acronym>JDK</acronym> is easy, change 
the executable bit for the downloaded file, change to the directory where you 
want it installed and execute the downloaded file.</para>

<para>The binary version is now installed.</para>

<para>If you don't want to compile the source, skip ahead to the configuration
section.</para>

<para>Add the recently compiled <acronym>JDK</acronym> to the path.</para>

<para>Unzip and patch the source:</para>

<screen><userinput><command>VERSION=&j2sdk-src-version; &amp;&amp;
V=`echo $VERSION | sed -e "s/\./_/g"` &amp;&amp;
unzip j2sdk-${V}-src-scsl.zip &amp;&amp;
unzip j2sdk-${V}-mozilla_headers-unix.zip &amp;&amp;

patch -Np1 -i j2sdk-${VERSION}-syntax-fixes.patch &amp;&amp;
patch -Np1 -i j2sdk-${VERSION}-use-included-motif.patch</command></userinput></screen>

<para>Set some vars which affect the build:</para>
<screen><userinput><command>export ALT_BOOTDIR="$JAVA_HOME" &amp;&amp;
unset JAVA_HOME &amp;&amp;
unset CLASSPATH
unset CFLAGS
unset CXXFLAGS
unset LDFLAGS
export ALT_DEVTOOLS_PATH="/usr/bin" &amp;&amp;
export BUILD_NUMBER="blfs-`date +%s`" &amp;&amp;
export DEV_ONLY=true &amp;&amp;
export ALT_MOZILLA_PATH=$PWD &amp;&amp;
export INSANE=true &amp;&amp;
export MAKE_VERBOSE=true &amp;&amp;
export ALT_CACERTS_FILE=${ALT_BOOTDIR}/jre/lib/security/cacerts</command></userinput></screen>

<para>Additionally, if you would like to make in parallel, add the following 
(adjust <envar>MAKE_PARALLEL</envar> to your liking):</para>
<screen><userinput><command>export HOTSPOT_BUILD_JOBS=$MAKE_PARALLEL</command></userinput></screen>

<para>The included <application>Motif</application> doesn't build properly with 
the current <application>Glibc</application>/<application>XFree86
</application>. A solution is to build the <application>Motif</application> 
library before compiling the <application>J2SDK</application>. Note that
the <application>Motif</application> build fails during the first run owing to 
some syntax error. The brute force and easiest solution is to rerun the
<command>make</command> command:)</para>

<screen><userinput><command>cd motif/lib/Xm &amp;&amp;
make || make &amp;&amp;
cd ../../..</command></userinput></screen>

<para>Make and Install <application>J2SDK</application> with the following 
commands. There will be a lot of messages about missing files that look like 
errors. As long as the build doesn't stop, the messages are harmless, so ignore 
them.</para>

<screen><userinput><command>cd control/make &amp;&amp;
make &amp;&amp;
cd ../.. &amp;&amp;
cd control/build/linux-i?86 &amp;&amp;
cp -a j2sdk-image /opt/j2sdk/j2sdk-&j2sdk-src-version;</command></userinput></screen>
