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 On Mon, Apr 27, 2015 at 8:23 AM, Bryan C.
