Fop Trunk Fails to Build (Linux, Ubuntu 9.04, x86_64, jdk1.6.0_14)

[Tom Browder]

I am getting lots of warnings errors building Fop (trunk, r784614), among them:

...

y-axis value.
    [javac]                                        ^

...

    [javac] The system is out of resources.

Ideas welcome.

Hi Tom,

I can build FOP without any problem on the same system (ok, jdk1.6.0_13
instead of jdk1.6.0_14 but that shouldn’t change anything really).

Are you sure you are actually running the Sun jdk? This is the usual
trap on Debian-based systems. Run ‘update-alternatives --display javac’
in a terminal. If it is not set to Sun’s jdk, you can set it like this:
    sudo update-java-alternatives -s java-6-sun

HTH,
Vincent

Thanks, Vincent.  That shows I'm not running the correct one all
right, but the second command didn't work.

Vincent, I don't understand the command.  I can trace the links back
to another javac.  My environment variables are:

JAVA_HOME=/opt/sun/java/latest
JAVABINDIR=/opt/sun/java/latest/bin

I can try to updated the links manually, but I'ld rather not.  This
appears as another piece of the java environment I'm not aware of.
What is "<jname>" supposed to refer to?  It's not a whole path, what
is the magic ID for a java installation? I''ll bet I have at least 10
around with various packages installed!

Thanks.

Regards,

-Tom

Ah, I see what /etc/alternatives is.   I've never been aware of that!

I know this is off topic, but what provides the /usr/lib/jvm/.*.jinfo file?

I think I can build my own, but that doesn't seem like it's something
a user should do.  Surely there exists one each for all standard Sun
Java packages.

Thanks and regards,

-Tom

That is all set now, but I still get the same errors.

Any more ideas?

Note that I cannot find directory "tools/com/sun/tools/javac" anywhere
on my system other than my build of the latest gcc.

See this message:

P.S.  Would someone like a test docbook xml file to give fop -pdf a
good workout?

Seems like a badly encoded 'smart quote'... I checked the file in my  
IDE, and noticed a similar substitution. I just replaced it with a  
regular apostrophe and committed the change: http://svn.apache.org/viewvc?rev=784924&view=rev

Well... The fact that your system has 4GB available does by no means  
guarantee that the JVM will use all of it, if it has to. Can you do  
anything to monitor the process closer?

I'll get that--thanks.

I'll try, but I have very little java experience (the only reason I'm
doing this is because I need to see if trunk/fop can -pdf gnucash
docbook xml docs, 0.95 can't; I don't know yet where that problem
is--I'm just trying to narrow the problem).

Hi Tom,

I assumed you installed the standard Debian package that provides the
Sun jdk, but if it is in /opt/sun/something this is probably not the
case. Any reason why you would need your own Sun Java installation?
Otherwise you can install the sun-java6-jdk package, and then you can
choose your favourite jvm using the update-java-alternatives command.

Also, you don’t need to set the JAVA_HOME and JAVABINDIR environment
variables at all.

I don’t know what the /usr/lib/jvm/.*.jinfo files are, but after years
of working on Debian-based systems I’ve never felt the need to know :-)

Make sure you are running the correct jvm by typing ‘javac -version’ on
the terminal.

Like Andreas said the jvm doesn’t usually use all the memory that’s
available on your system. You can set the maximum amount of memory
allocated to the jvm using the -Xmx parameter, but I’ve never had to do
that for building FOP. I’d first check that you are running the right
jvm, and then we can get back to how to use that switch later on.

HTH,
Vincent

I now have the debian jdk package installed, and it is apparently the
right one, but I'm getting the same problems.

I'll unset them and see if that makes any difference.  Note that over
the years there have been different sets of instructions with every
jvm and, for a non-java user, that has probably led to subtle system
conflicts that may be cropping up now.

My thought was trying to shoehorn the other jdk into the same group.

Will do.

You're always welcome to send FO files you're having problems with.  
Note: we'd rather not get the source XML, since that is strictly  
speaking out of scope for FOP. You could perform the initial XSLT  
stage using xsltproc or any other XSLT processor, then send the  
resulting file.
If the file is significantly large, please consider mailing it to us  
off-list or make it available otherwise, just to avoid bothering all  
list-subscribers with the attachment.


As to your initial problem: like Vincent, I've never run into memory-
related issues while /compiling/ FOP. I'd check (if possible) whether  
any restrictions are imposed at the level of the OS with respect to  
the maximum amount of memory any one process can consume at any given  
point. It may simply be that the JVM would expand the heap, but it  
cannot, since it is not allowed to do so...



HTH!

Okay, I still have the same problems with building from the trunk (r785169).

I have downloaded fop-0.95 and have different problems: build and test
errors.  A quick look indicates I may be missing something or have a
pre-req too old.  I will have to investigate later.  I will report
back.

Great, I'll do that.  If it's large, how about a zipped attachment?
If off-list, to whom?

You can send it to me (since I was the one who proposed to do so)

Well, I just tried to make the gnucash guide (from trunk) in pdf and
it worked.  However, there are some notes and warnings about features
not implemented, etc.  So it may make a good test case if you're still
interested.

I had difficulties running the JUnit-Tests included in the
default ant target, and I always run out of memory while
building javadocs on debian-amd64 using any sun jdk I tried.
Gcj was worse, it usually failed already at the codegen target
with rather strange errors (e.g. "illegal character in XML
file" WTF?) Maybe this is fixed now, I haven't tried for a
year or so.
I never had this kind of problems while building FOP on
Windows.

I'm still having heap space problems running fop on Ubunto 9.04..
Anyone have any ideas about what to do next?

Am I getting this correctly? You managed to build FOP, but now have  
memory issues while formatting a document?

If so, we have a number of things to look out for:

Yes, Andreas, I can build fop 0.95 (but with test failures, missing
fonts primarily).

I get heap space errors when trying to create a complex pdf document.
I will try the memory option to see what that does.
