Hi - is there a group of people working on OpenJDK 8 for OpenBSD?

[Bryan C. Everly]

So here are my steps to reproduce (I'm using the method of building from
source I found at
http://snatverk.blogspot.com/2014/02/how-to-install-java-18-from-source-code.html).
You can see where I hit a wall at the bottom of this email.

Any good ideas on how to proceed?

1.  Install OpenJDK 7

pkg_add jdk
echo "export JAVA_HOME=/usr/local/jdk-1.7.0" >> ~/.profile
export JAVA_HOME=/usr/local/jdk-1.7.0

2.  Install mercurial

pkg_add mercurial

3.  Install Antlr

pkg_add antlr
echo "export CLASSPATH=$CLASSPATH:/usr/local/share/java/classes/antlr3.jar"
>> ~/.profile
export CLASSPATH=$CLASSPATH:/usr/local/share/java/classes/antlr3.jar

4.  Install Ant

pkg_add apache-ant

5.  Install bash

pkg_add bash

6.  Install CUPS

pkg_add cups

7.  Clone the repository (I do this in a ~/work subdirectory)

hg clone http://openjdk.java.net/jdk8/jdk8

8.  Get the source code (this takes a long time):

cd jdk8
bash ./get_source.sh

9.  Run the configuration utility:

bash ./configure


*** HERE IS WHERE I HIT MY FIRST PROBLEM ***
The configure.sh script is looking for cups.h in /usr/include/cups/cups.h
and I couldn't find a way to override it.  This file lives in
/usr/local/include/cups instead.  To temporarily work around this, I
created a symlink in /usr/include so that the file could be "found" where
it is expected.  Any ideas on how to override this?

sudo ln -s /usr/local/include/cups /usr/include/cups
bash ./configure

10.  Clear out your current Java environment variables:

unset CLASSPATH
unset JAVA_HOME

11.  Build

gmake all

*** HERE IS WHERE I HIT MY SECOND PROBLEM ***
I get this weird error complaining about:

/usr/local/bin/gmake: invalid option -- 8
/usr/local/bin/gmake: invalid option -- /
/usr/local/bin/gmake: invalid option -- a
/usr/local/bin/gmake: invalid option -- /
/usr/local/bin/gmake: invalid option -- c

Did some Google searching and came up with this being a problem caused by
some regex trying to change something and that GMake 3.81 was ok with it.
I was skeptical but I downloaded the source for GMake 3.81, built it and
spliced it into my /usr/local/bin directory (preserving version 4.0 to roll
back to after this):

cd ~/work
wget https://ftp.gnu.org/gnu/make/make-3.81.tar.gz
tar -xzf make-3.81.tar.gz
rm make-3.81.tar.gz
cd make-3.81
bash ./configure
make
sudo mv /usr/local/bin/gmake /usr/local/bin/gmake.4
sudo cp make /usr/local/bin/gmake

cd ~/work/jdk8
gmake all

*** HERE IS WHERE I RAN OUT OF IDEAS ***
While compiling "../generated/adfiles/ad_x86_64_gen.cpp", I got the
following error:

cc1plus:  out of memory allocating 4072 bytes after a total of 110297968
bytes

The weird thing is that I had "vmstat -w 1" running in a separate XTerm
window and free memory was typically around 14 G so I don't really think I
ran out of ram in the system.  Is there some sort of heap size limitation
in the C++ compiler that we need to pass a parameter to expand?


Thanks,
Bryan
