JDK-1.5.0_11

The instructions below install both the binary and source versions. You may stop after installing the binary version or continue on installing the source version. You can choose to keep either or both.

Normally in BLFS, the files are unpacked into a subdirectory and the starting point for the installation procedures is that location. For this application only, start in the directory where all the downloaded files are located.

Install the precompiled JDK with the following commands:

install -m755 jdk-1_5_0_11-linux-i?86.bin jdk-mod.bin &&
sed -i "s:^PATH=.*::" jdk-mod.bin &&
./jdk-mod.bin &&
rm jdk-mod.bin

Now, as the root user:

cd jdk1.5.0_11 &&
install -v -m755 -d /opt/jdk/jdk-precompiled-1.5.0_11 &&
mv -v * /opt/jdk/jdk-precompiled-1.5.0_11 &&
chown -v -R root:root /opt/jdk/jdk-precompiled-1.5.0_11 &&
ln -v -sf motif21/libmawt.so \
    /opt/jdk/jdk-precompiled-1.5.0_11/jre/lib/i386/ &&
cd ..

The binary version is now installed.

If you don't want to compile the source or are not in a position to download the source owing to license restrictions, skip ahead to the configuration section.

Save the existing path, and append the recently installed JDK.

export JAVA_HOME=/opt/jdk/jdk-precompiled-1.5.0_11 &&
export PATH_HOLD=${PATH} &&
export PATH=${PATH}:${JAVA_HOME}/bin

The source code is contained in self-extracting jar files. You will need to be in a windowed environment to extract the sources. Create a directory to store the extracted sources. Choose the newly created jdk-build directory when prompted for the target directory.

mkdir jdk-build &&
cd jdk-build &&
for JAR in ../jdk-1_5_0_11*.jar
    do java -jar ${JAR}
done

Apply all the patches downloaded above:

for PATCH in ../jdk-1.5.0_11*.patch
    do patch -Np1 -i ${PATCH}
done

If your X Window System is installed into any prefix other than /usr/X11R6, execute the following command, replacing <PREFIX> with the installation prefix of the X Window System:

find . -type f -exec sed -i 's@/usr/X11R6@<PREFIX>@g' {} \;

Set/unset some variables which affect the build:

export ALT_BOOTDIR=${JAVA_HOME} &&
export CLASSPATH_HOLD=${CLASSPATH} &&
unset JAVA_HOME CLASSPATH CFLAGS CXXFLAGS LDFLAGS &&
export ALT_DEVTOOLS_PATH="/usr/bin" &&
export BUILD_NUMBER="update-10" &&
export DEV_ONLY=true &&
export ALT_MOZILLA_HEADERS_PATH=${PWD}/share/plugin/ &&
export INSANE=true &&
export MAKE_VERBOSE=true &&
export ALT_CACERTS_FILE=${ALT_BOOTDIR}/jre/lib/security/cacerts

Additionally, if you would like to make in parallel, add the following:

export HOTSPOT_BUILD_JOBS=<3>

Build the JDK with the following commands. There will be a few messages about missing files that look like errors. These are caused by not meeting the expected build environment (Red Hat). As long as the build doesn't stop, the messages are harmless.

pushd control/make &&
make &&
popd

To test the results, you can run one of the provided demo programs using the newly created java binary. Issue the following commands:

pushd control/build/linux-i?86/j2sdk-image/demo/jfc/Java2D &&
../../../bin/java -jar Java2Demo.jar &&
popd

Now, as the root user, install the JDK:

pushd control/build/linux-i?86 &&
cp -v -a j2sdk-image /opt/jdk/jdk-1.5.0_11 &&
chown -v -R root:root /opt/jdk/jdk-1.5.0_11 &&
ln -v -sf motif21/libmawt.so  /opt/jdk/jdk-1.5.0_11/jre/lib/i386/ &&
find /opt/jdk/jdk-1.5.0_11 \
     -type f -perm 600 -exec chmod -v 644 {} \; &&
find /opt/jdk/jdk-1.5.0_11 \
     -name "*.so" -exec chmod -v 755 {} \; &&
chmod -v 755 /opt/jdk/jdk-1.5.0_11/jre/bin/* &&
popd

Restore the unprivileged user's environment using the following commands:

export JAVA_HOME=${ALT_BOOTDIR} &&
export CLASSPATH=${CLASSPATH_HOLD} &&
export PATH=${PATH_HOLD} &&
unset ALT_BOOTDIR CLASSPATH_HOLD ALT_DEVTOOLS_PATH BUILD_NUMBER &&
unset DEV_ONLY ALT_MOZILLA_HEADERS_PATH INSANE MAKE_VERBOSE &&
unset ALT_CACERTS_FILE PATH_HOLD
