# This script creates a directory structure below /usr/lib/jvm and populates
|
||
|
|
# it with symlinks to GCC binaries.
|
||
|
|
# This will work as a compatibility layer to emulate an Oracle JDK/JRE.
|
||
|
|
# This emulation is required in order to compile OpenJDK using GNU java.
|
||
|
|
#
|
||
|
|
# The same can automatically be achieved in Slackware's gcc packages if
|
||
|
|
# the 'configure' command is called with the following additional parameters:
|
||
|
|
# --enable-java-home \
|
||
|
|
# --with-java-home=/usr/lib$LIBDIRSUFFIX/jvm/jre \
|
||
|
|
# --with-jvm-root-dir=/usr/lib$LIBDIRSUFFIX/jvm \
|
||
|
|
# --with-jvm-jar-dir=/usr/lib$LIBDIRSUFFIX/jvm/jvm-exports \
|

|

# --with-arch-directory=$LIB_ARCH \
