[pylucene-dev] Re: PyLucene install errors [was: JCC install errors]

[Alessandro Magni]

The ongoing problems continue:

1) I've been able to build/installed JCC, thanks to my (surprising!) 
discovery that I needed Sun's version of Java

Having installed it / setup the java alternatives, it worked by 
modifying the setup.py lines:

INCLUDES = {
...
    'linux2': ['/usr/lib/jvm/java-1.6.0-sun-1.6.0.04/include/',
                '/usr/lib/jvm/java-1.6.0-sun-1.6.0.04/include/linux'],
...
}

LFLAGS = {
...
    'linux2': [ 
'-L/usr/lib/jvm/java-1.6.0-sun-1.6.0.04/lib/i386:/usr/java/jdk1.6.0_04/jre/lib/i386/',
                 
'-Wl,-rpath=/usr/lib/jvm/java-1.6.0-sun-1.6.0.04/lib/i386:/usr/lib/jvm/java-1.6.0-sun-1.6.0.04/lib/i386
/client:/usr/java/jdk1.6.0_04/jre/lib/i386/'],
...
}

notice that I removed '-ljava' from LFLAGS - with it it didnt work: 
libjava.so not found, even if I have it in the indicated paths:
-rwxr-xr-x 1 root root 185K Dec 14 10:32 
/usr/java/jdk1.6.0_04/jre/lib/i386/libjava.so

... anyway, it compiled/installed, so why complain?


2) Then, I'vre removed one stumbling block from the PyLucene Makefile:
my problem was that "make" gave the result:

...
/usr/src/PyLucene-2.3.0-1/lucene-java-2.3.0/common-build.xml:474: Unable 
to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "/usr/java/jdk1.6.0_04/jre"
...

while, in fact, that variable is correct:
echo $JAVA_HOME
/usr/lib/jvm/java-1.6.0-sun-1.6.0.04/bin


Inspired by the "WINDOWS" section, I modified (in "linux2") the line so:

ANT=JAVA_HOME=/usr/lib/jvm/java-1.6.0-sun-1.6.0.04;ant


don't ask me why, but now the compile proceed much more (could you maybe 
update the Makefile with this change?)


BUT - it's not finished yet:

after working a lot, the make process stops here:

I don't understand the reason - I feel it may be related to my erasing 
the '-ljava' line in the setup.py of JCC.

What do you think about it?
