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

cryptic version) allows automatic installation.</para>

<warning><para>Setting CFLAGS/CXXFLAGS/LDFLAGS is guaranteed to make the build fail.

<para>Additionally, if you would like to make in parallel, add the following

<para>If the included <application>Motif</application> doesn't build properly, the

library before compiling the <application>J2SDK</application>.</para>

<para>Make and Install <application>J2SDK</application> with the following

them.</para>
