[BUG?] alienbob openjdk.SlackBuild
 
I'm building openjdk for current with the slackbuild of alienbob

I notice that line:
Code:

cp -a $PKG1/usr/lib${LIBDIRSUFFIX}/java/jre/lib/fontconfig.{Ubuntu,}.properties.src
This line create the file /usr/lib/java/jre/lib/fontconfig..properties.src
Is this correct or is a bug?
notice: the fontconfig.properties.src (with one only dot) already exists.


Some other notices:
I'm building in bootstrap mode, using gcc-java. In this mod gcc give me an error linking a library.
I correct this adding before "make" row:
Code:

sed -i -e 's/-o native-ecj/-lgcj -o native-ecj/' Makefile
Compiling on -current also there is not the "keytool" tools, so:
Code:

# Generate a cacerts file from the certificates installed through our
# ca-certificates package - the "cacerts" in the OpenJDK sources is empty.
# This will only work if we already have a proper JDK/JRE installed:
if which keytool 1>/dev/null 2>&1 ; then
...
else
  echo "** Not installing a proper cacerts file !"
  echo "** Missing keytool program (do you really have a Java installed?)"
fi

but, as workaround, I can do
Code:

perl generate-cacerts.pl ../openjdk.build/j2re-image/jre/bin/keytool all.crt
so I can popolate cacerts.

Another bug in package openjre:

Code:

# Symlinks are present in Slackware historically:
( cd $PKG2/usr/lib${LIBDIRSUFFIX}/java
  ln -sf jre jre${VERSION}
) || exit 1

should be
Code:

# Symlinks are present in Slackware historically:
( cd $PKG2/usr/lib${LIBDIRSUFFIX}
  ln -sf java jre${VERSION}
) || exit 1

as the slackware 13.37 jre6:
lrwxrwxrwx 1 root root 4 Apr 20 20:51 /usr/lib/jre1.6.0_27 -> java/

Not a bug. Do not compare the old Slackware package using Oracle binaries and my OpenJDK. I did this for a reason. There are some wrapper scripts that expect these directories. I did this on purpose.

Yes, that is a bug. There is a dot too many, I wanted to let the Ubuntu properties file overwrite the default one.

Never noticed this on Slackware 13.37 which was where I built the bootstrap version. I can add this to the SlackBuild if that helps people bootstrapping on Slackware-current. Now that there is a "final" version of OpenJDK there should not be a need for a bootstrap. I will see what happens when I bootstrap OpenJDK on ARM again sometime later.

For the bootstrap package, you do not need the cacerts file, so I did not bother with this. You don't want to run the bootstrap package on a daily basis. You should use the OpenJDK which is compiled against itself, because that is the only version which allows you to use icedtea-web. Once you have a proper OpenJDK package, you also have keytool.

I compare it becouse:
Code:

# Symlinks are present in Slackware historically:
Sound strange that a program expect the JRE in $JAVA_HOME/jre$VERSION/bin/java

Slackware 13.37 does not use gcc 4.7
This is a common problem for many software (and for many software are needed patch for gcc4.7). Now gcc require to explicitly specify some library to link.

who install slackware-current have no a jdk/openjdk installed.

After build openjdk with bootstrap I MUST to rebuild it with the newer openjdk?
I see that, when I start in bootstrap mode, that icedtee create openjdk.build-boot containing the openjdk compiled with gcc-java and then the openjdk.build compiled with the bootstrapped openjdk.
Code:

# ./openjdk.build/bin/javac -version
javac 1.7.0_05
# ./openjdk.build-boot/bin/javac -version
javac 1.7.0_05

Which are the differences with a version compiled without bootstrap?
For now I'd not compiled icedtea-web, so I can't verify

This is the log of the build.

You are interpreting that comment incorrectly. Slackware has versioned symlinks historically. But the location is not dictated by history. I only added a versioned symlink.

Yes. And the "sed" fix was mentioned in a comment by David Spencer on my blog post for the Update5: http://alien.slackbook.org/blog/upda...k-7-available/ . It will be present in the openjdk.SlackBuild when I compile the next JDK release.

Quote:

Yes, but you do not have to build this from source. Why do you think I provide a package already? If you want to bootstrap the build you have to respect the fact that that is not meant to be used in production.

A bootstrap build uses the java compiler of the GCC suite, which does not implement the full Java API as does the Oracle java compiler. Once you have the bootstrap build, you can rebuild OpenJDK and know that all the tools you need are installed. That is all I want to do. I have no real interest to keep building bootstrap packages. Once I had one JDK7 package, the bootstrap build was no longer needed. That will change once again, when OpenJDK moves to version 8 - OpenJDK can only be built using an existing OpenJDK of the same version, or else you have to do a bootstrap build.

I've tried but failed to do a bootstrap build on ARM because gcj needs so much memory. So I stole the Debian binaries and used them for a non-bootstrap build. This actually builds ok on x86_64! But on ARM it dies when something or other can't find JVM_SetNativeThreadName. Upstream is working on this, see http://blog.fuseyism.com/index.php/2...-zero-sort-of/, where your work has been noticed :) I tried to build with this fix from the Mercurial repo but got another build error when cacao rejected the -client control arg. Any further progress will probably be slow and painful.

TL;DR: if you value your time and sanity wait for icedtea 2.3 before you try it.
