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
Surprising ??
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
Removing -ljava is going to cause the problem you reported below.
... anyway, it compiled/installed, so why complain?
Yeah, complaining is not going to help either way.
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
Just as was suggested yesterday on this list. But, normally, you
shouldn't have to set JAVA_HOME at all. Ant can figure it out. Then,
maybe on redhat or on your install, it can't, in which case setting it
can work that around but without 'bin'.
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:

So you got ant to compile Lucene from sources. Now, you need to to
back to setup.py and add -ljava back to LFLAGS and rebuild jcc. This
missing symbol is in that libjava library you removed and jcc is not
going to function without it.
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?
You have the right feeling. If the jcc build failed with -ljava then
you've probably got a bug in LFLAGS in the
-L flags which tell the linker where to find the libs.
